[0026] Figure 1 It is a flow chart of the workpiece processing control method provided by an embodiment of the present invention. The workpiece processing control method provided by an embodiment of the present invention can be applicable to the scenario of using machine tools to process high-precision workpieces. The workpiece processing control method can be executed by the workpiece processing control device provided by an embodiment of the present invention, and the device can be implemented in software and / or hardware. The workpiece processing control device can be integrated into an electronic device, and the electronic device can be a personal computer, a computer, a server, etc. In this embodiment, the electronic device can be integrated into the machine tool equipment as a control system of the machine tool equipment, and can also be used as a back-end device that has a communication connection relationship with the machine tool to control the operation of the machine tool. The following embodiment takes the integration of the workpiece processing control device in the electronic device as an example, refer to Figure 1 The workpiece processing control method of this embodiment may include the following steps:

[0027] Step 110, monitoring the real-time operating temperature of the machine tool.

[0028] Among them, the machine tool is a machine for manufacturing machines and machinery. In this embodiment, the machine tool is mainly a CNC EDM machine tool, which belongs to electrical processing equipment. The principle of EDM machine tool processing workpieces is: use conductive materials (such as copper, graphite, etc.) as electrodes, the electrodes are at positive potential, the workpiece is at zero potential, and a high-frequency pulse voltage is applied between the electrode and the workpiece. When the distance between the two is very close, electric sparks will be generated between the two. The high-temperature electric sparks cause the workpiece material to partially melt and vaporize, and are removed with the working fluid.

[0029] Specifically, when a machine tool is needed to process a workpiece, or during the processing, a temperature monitoring device can be used to monitor the real-time working temperature of the machine tool. Exemplarily, the temperature monitoring device can be a temperature sensor, a thermometer, or a temperature tester. In addition, the temperature monitoring device can be installed in the working area of ​​the machine tool, or in the key component area, to monitor the real-time working temperature of the machine tool. Optionally, one or more temperature monitoring devices can be installed at each key component of the machine tool to accurately monitor the real-time working temperature of the machine tool.

[0030] In this embodiment, by monitoring the real-time working temperature of the machine tool, when using the machine tool to process high-precision workpieces, the change of the working temperature can be determined in time, and corresponding compensation measures can be taken to cope with the temperature change, thereby ensuring the stability of the processing process and improving the processing quality. In addition, the real-time working temperature can provide a data basis for the subsequent determination of the processing control method of the workpiece.

[0031] Step 120, determining the deformation amount of the machine tool at the real-time working temperature, and determining the deformation amount of the workpiece processed on the machine tool at the real-time working temperature.

[0032] Among them, the deformation refers to the amount of change in the shape of an object when its shape changes. In this embodiment, the deformation of the machine tool refers to the amount of change in the stroke of the key parts in the machine tool, that is, the size change of the key parts in the machine tool. For example, the key parts are instruments on the machine tool for measuring the size of the workpiece. The deformation of the workpiece refers to the size change of the workpiece. In this embodiment, deformation includes expansion and contraction. Too high a temperature will cause the material to expand, and too low a temperature will cause the material to contract.

[0033] Specifically, since different materials have different material temperature coefficients or deformation expansion coefficients, machine tools made of different materials and workpieces made of different materials will have different degrees of deformation when working at different working temperatures. Therefore, it is necessary to determine the deformation amount of the machine tool at the real-time working temperature based on the material temperature coefficient of the machine tool material, and to determine the deformation amount of the processed workpiece at the real-time working temperature based on the material temperature coefficient of the processed workpiece material.

[0034] For example, in one implementation, a high-precision measuring instrument is directly used to measure the deformation of the machine tool and the workpiece, for example, a laser instrument is used to measure the deformation. In another implementation, since each material has a corresponding material temperature coefficient or deformation expansion coefficient, the material temperature coefficient or deformation expansion coefficient corresponding to the machine tool can be directly determined according to the material of the machine tool, and the deformation of the machine tool at the real-time working temperature can be determined. And, the material temperature coefficient or deformation expansion coefficient corresponding to the processed workpiece is directly determined according to the material of the processed workpiece, and the deformation of the processed workpiece at the real-time working temperature is determined. Among them, the material temperature coefficient is an indicator to measure the change of the physical properties of the material with temperature. The deformation expansion coefficient characterizes the degree of change of the length, area, and volume of the object when it is heated. In another implementation, the machine tool and the processed workpiece can be experimented or tested in advance. For example, the deformation of the machine tool at different temperatures is determined, and the mapping relationship between the deformation of the machine tool and the temperature is determined based on the deformation of the machine tool at different temperatures. And, the deformation of different workpieces at different temperatures is determined, and the mapping relationship between the deformation of different workpieces and the temperature is determined based on the deformation of different workpieces at different temperatures. The mapping relationship can be presented in the form of a table, a curve, a function, or other forms. After the change mapping relationship is determined through experiments or tests, the deformation amount of the machine tool at the real-time working temperature and the deformation amount of the workpiece at the real-time working temperature can be determined directly based on the real-time working temperature and the change mapping relationship.

[0035] For example, since the machine tool and the workpiece may be made of different materials, only one of the machine tool and the workpiece may be deformed at the real-time working temperature. Therefore, the calculated deformation amount of the machine tool at the real-time working temperature or the deformation amount of the workpiece at the real-time working temperature may be zero.

[0036] In this embodiment, the deformation of the machine tool at the real-time working temperature is determined, and the deformation of the workpiece processed on the machine tool at the real-time working temperature is determined. By determining the degree of deformation of the machine tool and the processed workpiece during the processing in real time, the deformation monitoring of the machine tool and the processed workpiece during the processing is realized. This not only ensures that the deformation degree of the machine tool and the processed workpiece will not exceed the normal deformation degree during the processing, but also provides data support for determining the processing control method based on the deformation degree of the two.

[0037] Step 130 , calculating the difference between the deformation of the tool machine at the real-time working temperature and the deformation of the workpiece at the real-time working temperature, and obtaining the deformation difference.

[0038] Specifically, since the materials of the machine tool and the workpiece may be different, the deformation of the machine tool and the workpiece are different at the same real-time working temperature during the actual processing. At this time, in order to ensure the working accuracy of the machine tool when processing the workpiece, it is necessary to determine the change difference of the deformation of the machine tool and the workpiece at the real-time temperature.

[0039] Exemplarily, the deformation of the machine tool at the real-time working temperature minus the deformation of the workpiece at the real-time working temperature can obtain the deformation difference. Among them, the deformation difference may be positive, negative or zero. If the deformation difference is a positive value, it means that the deformation of the machine tool at the real-time working temperature is greater than the deformation of the workpiece at the real-time working temperature. If the deformation difference is a negative value, it means that the deformation of the machine tool at the real-time working temperature is less than the deformation of the workpiece at the real-time working temperature. If the deformation difference is zero, it means that the deformation of the machine tool at the real-time working temperature is equal to the deformation of the workpiece at the real-time working temperature.

[0040] It is worth noting that the deformation of the workpiece at the real-time working temperature minus the deformation of the machine tool at the real-time working temperature can also be calculated to obtain the deformation difference. In this case, the situation where the deformation difference is positive or negative is the opposite of that described in the above embodiment.

[0041] In this embodiment, the difference between the deformation of the machine tool at the real-time working temperature and the deformation of the workpiece at the real-time working temperature is calculated to obtain the deformation difference, thereby determining the difference in the degree of change of the machine tool and the workpiece at the real-time working temperature. Based on the difference in the degree of change, the precision error between the machine tool and the workpiece during processing caused by the change in working temperature can be accurately determined.

[0042] Step 140, adjusting the movement feed of the machine tool according to the deformation difference.

[0043] The term "feeding" refers to the process of moving the workpiece toward the tool or the tool toward the workpiece during continuous operation. In this embodiment, the term "movement feeding" is used to indicate the movement amount of the machine tool to move the workpiece toward the tool or the tool toward the workpiece.

[0044] Specifically, since the real-time working temperature may have different effects on the machine tool and the workpiece, there will be an error between the movement amount in the actual processing process and the movement amount determined in the theoretical calculation. Therefore, it is necessary to determine the movement feed adjustment amount of the machine tool based on the difference in deformation between the machine tool and the workpiece at the real-time working temperature, so that the machine tool can control the tool to accurately process the workpiece according to the movement feed adjustment amount.

[0045] Exemplarily, it can be determined first based on the deformation difference that the real-time working temperature has a greater influence on the machine tool and the workpiece under the real-time working temperature. For example, if the deformation difference is a positive value, it means that the deformation of the machine tool is greater than the deformation of the workpiece. Therefore, the influence of the real-time working temperature on the machine tool is greater than the influence on the workpiece. Therefore, in the actual processing process, the actual processing movement will be longer than the movement determined in the theoretical calculation, so it is necessary to reduce the movement feed of the machine tool based on the deformation difference to compensate for the processing error caused by the deformation difference of the machine tool more than the workpiece. If the deformation difference is a negative value, it means that the deformation of the machine tool is less than the deformation of the workpiece. Therefore, the influence of the real-time working temperature on the machine tool is less than the influence of the workpiece. Therefore, in the actual processing process, the actual processing movement will be shorter than the movement determined in the theoretical calculation, so it is necessary to increase the movement feed of the machine tool based on the deformation difference to compensate for the processing error caused by the deformation difference of the machine tool less than the workpiece. If the deformation difference is zero, it means that the deformation of the machine tool is equal to the deformation of the workpiece. Therefore, the real-time working temperature has the same impact on the machine tool as the workpiece. At this time, since the machine tool and the workpiece move at the same time and move the same distance, there is no need to adjust the moving feed amount.

[0046] In this embodiment, the movement feed of the machine tool is adjusted according to the difference in deformation amount, so as to compensate for the deformation difference caused by temperature and reduce the requirement for working temperature, so that workpieces meeting the precision requirement can be processed at various temperatures. The problem of high cost caused by using ultra-high precision air conditioning to ensure constant temperature during processing is solved, and the cost is reduced. The problem of low control precision due to the difficulty in achieving constant temperature during processing based on controlling the air conditioner is solved, and the control precision is improved.

[0047] In this embodiment, the real-time working temperature of the machine tool is monitored, and the real-time working temperature can provide a data basis for the subsequent determination of the processing control method of the workpiece; the deformation of the machine tool at the real-time working temperature is determined, and the deformation of the workpiece processed on the machine tool at the real-time working temperature is determined. By determining the deformation degree of the machine tool and the processed workpiece during the processing in real time, the deformation monitoring of the machine tool and the processed workpiece during the processing is realized, which not only ensures that the deformation degree of the machine tool and the processed workpiece will not exceed the normal deformation degree during the processing, but also provides data support for determining the processing control method based on the deformation degree of the two. The difference between the deformation of the machine tool at the real-time working temperature and the deformation of the workpiece at the real-time working temperature is calculated to obtain the deformation variable The difference can be used to determine the difference in the degree of change of the machine tool and the workpiece in the real-time working temperature. Based on the difference in the degree of change, the precision error caused by the change in the working temperature between the machine tool and the workpiece during processing can be accurately determined; the movement feed of the machine tool is adjusted according to the deformation difference, which realizes the compensation for the deformation difference caused by temperature and reduces the requirement for working temperature, so that workpieces that meet the precision requirements can be processed at various temperatures, which solves the problem of high cost caused by using ultra-high precision air conditioning to ensure constant temperature during processing, reduces costs, and solves the problem of low control accuracy due to the difficulty in achieving constant temperature during processing based on controlling air conditioning, thereby improving control accuracy.

[0048] The following further describes the workpiece processing control method provided by the embodiment of the present invention. Figure 2 As shown, the method of this embodiment includes:

[0049] Step 201 , using temperature sensors provided at various components of the machine tool to monitor the temperature at the corresponding components, and obtaining multiple temperatures.

[0050] Among them, the various components of the machine tool may be important parts of the machine tool, such as a spindle, a worktable, a lead screw, and a guide rail.

[0051] Specifically, a temperature sensor may be provided at each important component of the machine tool, and the temperature at each important component is monitored based on the temperature sensor to obtain the temperatures at multiple components.

[0052] Step 202, determining the real-time operating temperature based on multiple temperatures.

[0053] Specifically, after obtaining the temperatures at multiple components, in one implementation, the average temperature of the multiple temperatures can be calculated based on the temperatures at the multiple components, and the average temperature can be determined as the real-time working temperature of the machine tool. In another implementation, the temperature corresponding to the most important component can be directly used as the real-time working temperature of the machine tool based on the importance of each component. For example, a component in a machine tool that measures the amount of moving feed. Alternatively, the temperature with the largest temperature value among the multiple temperatures can be used as the real-time working temperature of the machine tool. Among them, the importance of each component can be determined based on the degree of influence of temperature on the deformation of each component, the degree of use of each component in the processing process, and the distance of each component from the processing center.

[0054] In this embodiment, the temperature sensors provided at various parts of the machine tool are used to monitor the temperature at the corresponding parts, and multiple temperatures are obtained. The real-time working temperature is determined based on the multiple temperatures, so that the temperature monitoring of different parts in the machine tool is realized. Based on the temperature monitoring of different parts, the change of the working temperature is determined, and corresponding compensation measures are taken based on the real-time working temperature to cope with the temperature change, thereby ensuring the stability of the processing process and improving the processing quality. In addition, the real-time working temperature can provide a data basis for the subsequent determination of the processing control method of the workpiece.

[0055] Step 203, determining the standard operating temperature of the machine tool according to the material of the machine tool.

[0056] Among them, at the standard operating temperature, the object of this material can ensure stable operation without invisible variables. The standard operating temperature is usually a temperature value. Optionally, the material of the machine tool is generally gray cast iron.

[0057] Specifically, in one implementation, the standard operating temperature of the machine tool can be determined directly based on the material temperature coefficient or deformation expansion coefficient of the machine tool material. In another implementation, the relevant personnel determine the degree of change of the machine tool at different temperature values ​​through experiments or tests based on machine tools of different materials, and directly determine the standard operating temperature of machine tools of different materials. The standard operating temperatures of machine tools of different materials are preset or directly stored, and when it is necessary to determine the standard operating temperature of the machine tool, the preset or stored standard operating temperature is directly obtained.

[0058] Step 204, determine whether the standard operating temperature of the machine tool is the same as the real-time operating temperature; if so, return to execute S201; if not, execute S205.

[0059] Specifically, when the standard operating temperature of the machine tool is determined, it is determined whether the standard operating temperature of the machine tool is the same as the real-time operating temperature. If the standard operating temperature value of the machine tool is the same as the real-time operating temperature value, it means that the machine tool will not be deformed, and the process returns to the step of "using the temperature sensors provided at each component of the machine tool to monitor the temperature at the corresponding component to obtain multiple temperatures". If the standard operating temperature value of the machine tool is different from the real-time operating temperature value, it means that the machine tool will be deformed, and the process continues to execute the step of "calculating the difference between the standard operating temperature of the machine tool and the real-time operating temperature to obtain the first temperature difference".

[0060] Optionally, step 203-step 204 is to judge the working temperature of the machine tool. In the actual process, the working temperature of the workpiece can also be judged. Exemplarily, the standard working temperature of the workpiece can be determined according to the material of the workpiece, and it can be judged whether the standard working temperature of the workpiece is the same as the real-time working temperature; if so, return to execute S201; if not, execute S205. Among them, the material of the workpiece is generally steel, the method for determining the standard working temperature of the workpiece can be the same as the method for determining the standard working temperature of the machine tool, and the method for judging whether the standard working temperature of the workpiece is the same as the real-time working temperature can be consistent with the method for judging whether the standard working temperature of the machine tool is the same as the real-time working temperature.

[0061] It is worth noting that the step of "determining the standard operating temperature of the machine tool" can be executed in parallel with the step of "determining the standard operating temperature of the workpiece", and the step of "determining whether the standard operating temperature of the machine tool is the same as the real-time operating temperature" can be executed in parallel with the step of "determining whether the standard operating temperature of the workpiece is the same as the real-time operating temperature". In addition, only when it is determined that the standard operating temperature of the machine tool is the same as the real-time operating temperature, and the standard operating temperature of the workpiece is the same as the real-time operating temperature, that is, neither the machine tool nor the workpiece will be deformed, can the process return to S201. Otherwise, the process will continue to execute S205.

[0062] Step 205, calculating the difference between the standard operating temperature and the real-time operating temperature of the tool machine to obtain a first temperature difference.

[0063] Specifically, if the standard operating temperature of the machine tool is different from the real-time operating temperature, it means that the machine tool may have generated a deformation amount. Therefore, the difference between the standard operating temperature of the machine tool and the real-time operating temperature can be calculated, and the difference can be used as the first temperature difference. The first temperature difference can be a positive value or a negative value.

[0064] Step 206, determining the temperature deformation coefficient of the machine tool according to the material of the machine tool.

[0065] Specifically, the temperature deformation coefficient of the machine tool is determined according to the material of the machine tool. A preset mapping relationship may be queried based on the material of the machine tool to obtain the temperature deformation coefficient of the machine tool.

[0066] The preset mapping relationship includes mapping relationships between various materials and temperature deformation coefficients. For example, the mapping relationships between various materials and temperature deformation coefficients included in the preset mapping relationship can be obtained based on the various methods mentioned above to determine the temperature deformation coefficient of the machine tool, and stored as a preset mapping relationship for subsequent use.

[0067] Step 207, calculating the deformation amount of the machine tool at the real-time working temperature according to the size of the machine tool, the temperature deformation coefficient and the first temperature difference.

[0068] In this embodiment, the size of the machine tool may refer to the size of each key component in the machine tool, or may refer to the size of a component in the machine tool that measures the moving feed amount.

[0069] Specifically, the size of the machine tool is obtained, and the size can be determined based on the rated data of the machine tool, or can be determined by measuring with a high-precision measuring tool. After the size of the machine tool, the temperature deformation coefficient of the machine tool, and the first temperature difference are determined, the deformation amount of the machine tool when the temperature changes by one degree can be determined based on the temperature deformation coefficient of the machine tool and the size of the machine tool. And based on the deformation amount of the machine tool when the temperature changes by one degree and the first temperature difference, the deformation amount of the machine tool at the real-time working temperature is determined.

[0070] For example, assuming that the machine tool material is gray cast iron, its corresponding temperature deformation coefficient is 9×10 -6 , that is, when the temperature rises by 1 degree, the gray cast iron with a length of 100 mm will expand to 100.0009 mm. Assuming that the first temperature difference is 2 degrees, the expansion length of the machine tool is 0.0018 mm at the first temperature difference.

[0071] In this embodiment, when it is determined that the standard operating temperature of the machine tool is different from the real-time operating temperature, the first temperature difference between the standard operating temperature of the machine tool and the real-time operating temperature is calculated, the temperature deformation coefficient of the machine tool is determined according to the material of the machine tool, and the deformation amount of the machine tool at the real-time working temperature is calculated according to the size of the machine tool, the temperature deformation coefficient and the first temperature difference. This realizes the accurate calculation of the deformation amount of the machine tool at the real-time working temperature based on the temperature change of the machine tool, the temperature deformation coefficient reflecting the relationship between the temperature change and the deformation amount, and the size of the machine tool.

[0072] Step 208, determining the standard operating temperature of the workpiece according to the material of the workpiece, and calculating the difference between the standard operating temperature and the real-time operating temperature of the workpiece to obtain a second temperature difference.

[0073] Specifically, the standard operating temperature of the workpiece may be determined based on a method such as “determining the standard operating temperature of a machine tool”, and the temperature difference between the standard operating temperature and the real-time operating temperature of the workpiece may be calculated to obtain the second temperature difference.

[0074] Step 209, determining the temperature deformation coefficient of the workpiece according to the material of the workpiece.

[0075] Specifically, the temperature deformation coefficient of the workpiece is determined according to the material of the workpiece. A preset mapping relationship may be queried based on the material of the workpiece to obtain the temperature deformation coefficient of the workpiece.

[0076] For example, the preset mapping relationship can be obtained based on the various methods mentioned above to determine the temperature deformation coefficient of the workpiece, and stored as a preset mapping relationship for subsequent use. In addition, the preset mapping relationship can include the mapping relationship between machine tools of various materials and workpieces of various materials and temperature deformation coefficients.

[0077] Step 210, calculating the deformation amount of the workpiece at the real-time working temperature according to the size of the workpiece, the temperature deformation coefficient and the second temperature difference.

[0078] Specifically, the size of the workpiece is obtained, and the size of the workpiece can be obtained in the same way as the size of the machine tool. After determining the size of the workpiece, the temperature deformation coefficient of the workpiece, and the second temperature difference, the deformation amount of the workpiece when the temperature changes by one degree can be determined based on the temperature deformation coefficient of the workpiece and the size of the workpiece. And based on the deformation amount of the workpiece when the temperature changes by one degree and the second temperature difference, the deformation amount of the workpiece at the real-time working temperature is determined.

[0079] For example, assuming that the workpiece material is steel, its corresponding temperature deformation coefficient is 13×10 -6 , that is, when the temperature rises by 1 degree, a 100mm long steel workpiece will expand to 100.0013mm. Assuming that the second temperature difference is 1 degree, the expansion length of the workpiece under the second temperature difference is determined to be 0.0013mm.

[0080] Step 211, calculating the difference between the deformation of the tool machine at the real-time working temperature and the deformation of the workpiece at the real-time working temperature, and obtaining the deformation difference.

[0081] Specifically, the deformation difference can be obtained by subtracting the deformation of the workpiece at the real-time working temperature from the deformation of the machine tool at the real-time working temperature.

[0082] Exemplarily, following the above example, by subtracting the deformation of the workpiece at the real-time working temperature, which is 0.0018 mm, from the deformation of the machine tool at the real-time working temperature, which is 0.0013 mm, it can be determined that the deformation difference is 0.0005 mm.

[0083] In this embodiment, the difference between the deformation of the machine tool at the real-time working temperature and the deformation of the workpiece at the real-time working temperature is calculated to obtain the deformation difference, thereby determining the difference in the degree of change of the machine tool and the workpiece at the real-time working temperature. Based on the difference in the degree of change, the precision error between the machine tool and the workpiece during processing caused by the change in working temperature can be accurately determined.

[0084] Step 212: when the deformation difference indicates that the deformation of the machine tool at the real-time working temperature is less than the deformation of the workpiece at the real-time working temperature, the movement feed of the machine tool is increased according to the deformation difference.

[0085] Specifically, if the deformation difference indicates that the deformation of the machine tool at the real-time working temperature is smaller than the deformation of the workpiece at the real-time working temperature, it means that the actual processing path of the workpiece is smaller than the theoretically calculated processing path. Therefore, the mobile feed of the machine tool needs to be increased to compensate for the precision error caused by the deformation of the workpiece and the machine tool due to temperature. At this time, the deformation difference can be added to the original mobile feed path length to obtain the adjusted mobile feed value of the machine tool.

[0086] For example, following the above example, assume that the difference in deformation between the machine tool and the workpiece is -0.0004mm, that is, the deformation of the machine tool at the real-time working temperature is less than the deformation of the workpiece at the real-time working temperature. At this time, if the mobile feed value before adjustment is 100mm, the mobile feed value after adjustment is 100mm+0.0004mm=100.0004mm.

[0087] Step 213, when the deformation difference indicates that the deformation of the machine tool at the real-time working temperature is greater than the deformation of the workpiece at the real-time working temperature, the movement feed of the machine tool is reduced according to the deformation difference.

[0088] Specifically, if the deformation difference indicates that the deformation of the machine tool at the real-time working temperature is greater than the deformation of the workpiece at the real-time working temperature, it means that the actual workpiece processing path is greater than the theoretically calculated processing path. Therefore, the machine tool's mobile feed amount needs to be reduced to compensate for the precision error caused by the deformation of the workpiece and the machine tool caused by temperature. At this time, the deformation difference can be subtracted from the original mobile feed path length to obtain the adjusted machine tool mobile feed value.

[0089] For example, following the above example, assume that the difference in deformation between the machine tool and the workpiece is 0.0004 mm, that is, the deformation of the machine tool at the real-time working temperature is greater than the deformation of the workpiece at the real-time working temperature. At this time, if the mobile feed value before adjustment is 100 mm, the mobile feed value after adjustment is 100 mm-0.0004 mm=99.9996 mm.

[0090] Optionally, the deformation difference can also be 0, that is, the deformation difference indicates that the deformation of the machine tool at the real-time working temperature is equal to the deformation of the workpiece at the real-time working temperature. In this case, there is no need to adjust the movement feed amount of the machine tool.

[0091] In this embodiment, the movement feed of the machine tool is adjusted according to the difference in deformation, so as to compensate for the deformation difference caused by temperature, reduce the requirements for working temperature, and enable workpieces that meet the precision requirements to be processed at various temperatures, thereby solving the problem of high cost caused by the need to ensure constant temperature during processing and using ultra-high precision air conditioners, thereby reducing costs. In addition, the problem of low control accuracy due to the difficulty in achieving constant temperature during processing based on controlling air conditioners is solved, thereby improving control accuracy.

[0092] In this embodiment, the temperature sensors provided at various components of the machine tool are used to monitor the temperature at the corresponding components to obtain multiple temperatures, and the real-time working temperature is determined based on the multiple temperatures, thereby realizing temperature monitoring of different components in the machine tool, and based on the temperature monitoring of different components, providing a data basis for the subsequent determination of the processing control method of the workpiece; based on the standard working temperature and the real-time working temperature of the machine tool, it is determined whether the machine tool is currently in a non-deformed state, and when it is determined that the standard working temperature of the machine tool is the same as the real-time working temperature, it is realized to continue to monitor the temperature of various components of the machine tool, thereby ensuring real-time monitoring of temperature changes; when it is determined that the standard working temperature of the machine tool is different from the real-time working temperature, the first temperature difference between the standard working temperature of the machine tool and the real-time working temperature is calculated, the temperature deformation coefficient of the machine tool is determined according to the material of the machine tool, and the deformation of the machine tool at the real-time working temperature is calculated according to the size of the machine tool, the temperature deformation coefficient and the first temperature difference, thereby realizing the temperature change according to the machine tool. The deformation of the machine tool at the real-time working temperature is accurately calculated by measuring the temperature deformation coefficient that reflects the relationship between temperature change and deformation, and the size of the machine tool; the difference between the deformation of the machine tool at the real-time working temperature and the deformation of the workpiece at the real-time working temperature is calculated to obtain the deformation difference, thereby determining the difference in the degree of change of the machine tool and the workpiece at the real-time working temperature. Based on the difference in the degree of change, the precision error caused by the change in the working temperature between the machine tool and the workpiece during processing can be accurately determined; the movement feed of the machine tool is adjusted according to the deformation difference, compensation for the deformation difference caused by temperature is realized, the requirements for the working temperature are reduced, and workpieces that meet the precision requirements can be processed at various temperatures, which solves the problem of high cost caused by using ultra-high precision air conditioning to ensure constant temperature during processing, reduces costs, and solves the problem of low control accuracy due to the difficulty in achieving constant temperature during processing based on controlling air conditioning, thereby improving control accuracy.
