[0050] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0051] Secondly, it should be noted that in the description of the embodiments of this application, the terms "inner" and "outer" and other terms indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0052] Furthermore, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] With the rapid development of machining technology, accurate control of process parameters in actual production and manufacturing can greatly improve the quality of machined parts, and has a significant impact on extending tool life and improving enterprise production efficiency. Among them, machining includes CNC machining, which refers to a process method of machining parts on CNC machine tools.

[0055] This application takes deep hole drilling as an example. In the prior art, when drilling with a drilling tool, such as a deep hole drill, the feed rate of the deep hole drill is set in advance in the CNC (Computer Numerical Control) program in the CNC machine tool programming software based on the size of the deep hole drill, the depth of the hole, whether there is a through hole, and other processing parameters, as well as the experience of the process personnel. When the deep hole drill performs drilling operations according to the CNC program, it drills at the set constant feed rate.

[0056] However, drilling is a non-linear, time-varying process with complex dynamic characteristics. Current technologies lack any feedback on actual conditions during drilling operations, consistently maintaining a constant feed rate. This can easily lead to chipping or even tool breakage during deep hole drilling, reducing processing efficiency.

[0057] Therefore, to address the aforementioned technical problems of the prior art, this application proposes a drilling control method, apparatus, equipment, and medium. By collecting the real-time power of the machine tool spindle during drilling operations, and based on the real-time power, an adjustment algorithm is used to calculate the real-time feed rate of the drilling tool during drilling operations. Based on the real-time feed rate, the real-time feed speed of the drilling tool is controlled to ensure that the drilling tool performs drilling at the specified feed speed. This application, through real-time control of the drilling tool's feed speed during drilling operations, reduces the occurrence of tool chipping or breakage during operation, extends the service life of the drilling tool, and improves processing efficiency.

[0058] This application can be used in machining hole scenarios, such as machining deep holes with deep hole drilling, reaming with twist drills, and machining center holes with center drills. By adaptively controlling the feed rate of the drilling tool during the drilling process, stable drilling is achieved, extending the service life of the drilling tool. It is understood that the drilling control method proposed in this application includes, but is not limited to, the above-mentioned drilling scenarios, and the listed scenarios are not intended to limit this application.

[0059] The principles and features of the embodiments of this application are described below with reference to the accompanying drawings. The examples given are only used to explain the embodiments of this application and are not intended to limit the scope of the embodiments of this application.

[0060] It should be noted that the embodiments of this application do not limit the actual form of various devices in the application scenario, nor do they limit the interaction method between devices. In the specific application of the solution, it can be set according to actual needs.

[0061] In this application, the executing entity of the drilling control method can be a CNC system, or a device or equipment integrating hardware or software with CNC system functions. This application uses a CNC system as an example for illustration. The CNC system is a program control system that can logically process the CNC machining program input into the system, control the movement of the CNC machine tool, and machine parts.

[0062] Figure 1 This is a flowchart illustrating a drilling control method provided in Embodiment 1 of this application, as shown below. Figure 1 As shown, the method specifically includes the following steps:

[0063] S101. Collect the real-time power of the machine tool spindle during drilling operations.

[0064] In the CNC system of this embodiment, its basic components include, but are not limited to, a CNC machine tool, a testing device, a computer numerical control (CNC) device, a spindle servo drive device, and a feed servo drive device. The machine tool spindle is connected to a drilling tool and is used to drive the drilling tool to drill holes. The CNC device of the CNC system has an embedded computer numerical control program, which contains relevant calculation formulas or algorithms required during the drilling operation. The drilling tool can be a deep hole drill, etc., and this application does not limit the type of drilling tool.

[0065] The detection device can be a high-precision current sensor, which is used to collect the real-time power of the machine tool spindle during drilling operations.

[0066] Specifically, the current sensor collects the current of the machine tool spindle and the voltage of the machine tool spindle driver. Based on the relationship between power, current and voltage, the real-time power of the machine tool spindle can be calculated.

[0067] Alternatively, the detection device can also be a power sensor, which can directly collect the real-time power of the machine tool spindle during the drilling operation of a deep hole drill. This application does not limit the specific physical device of the detection device. Any physical device that can indirectly or directly collect the real-time power of the machine tool spindle and has a certain degree of compatibility with the CNC system is acceptable.

[0068] It is understandable that the change in the spindle power of the machine tool indicates that the torque between the deep hole drill and the workpiece has changed, further demonstrating that the drilling process is a nonlinear, time-varying process with complex dynamic characteristics.

[0069] S102. Based on the real-time power, calculate the real-time feed rate of the drilling tool during the drilling operation using an adjustment algorithm.

[0070] The computer numerical control program stores relevant programs and algorithms for drilling, including an adjustment algorithm. This adjustment algorithm is specifically used to calculate the real-time feed rate of the drilling tool based on the real-time power collected by the current sensor.

[0071] S103. Based on the real-time feed ratio, control the real-time feed speed of the drilling tool to control the drilling tool to perform drilling at the feed speed.

[0072] In the CNC system, the preset feed rate for deep hole drilling has been set based on empirical values ​​of the feed rates required for machining other workpieces.

[0073] It is important to note that when setting the preset feed rate, it is necessary to consider whether other workpieces have the same or similar material as the workpiece being machined, and whether the drilling tools used when machining other workpieces are the same as those used for the workpiece being machined.

[0074] After calculating the real-time feed ratio of the drilling tool in step S102, the real-time feed speed of the drilling tool is controlled according to the relationship between the real-time feed ratio and the real-time feed speed.

[0075] Specifically,

[0076] The real-time feed rate is obtained by multiplying the preset feed rate by the real-time feed rate.

[0077] The feed rate of the drilling tool is controlled based on the real-time feed rate.

[0078] One feasible implementation is:

[0079] Based on the real-time feed rate, the drilling tool is controlled to drill at the real-time feed rate via an embedded programmable controller. This programmable controller can be a PLC (Programmable Logic Controller), etc.

[0080] Another feasible implementation is:

[0081] Based on the real-time feed rate, the drilling tool is controlled to drill at the real-time feed rate via an external adjustable rate switch.

[0082] In the above embodiments of this application, the real-time power of the machine tool spindle during drilling is collected, and the real-time feed rate of the drilling tool is calculated using an adjustment algorithm based on the real-time power. Based on the real-time feed rate, the real-time feed speed of the drilling tool is controlled to ensure that the drilling tool performs drilling at the specified feed speed. This method, through real-time control of the drilling tool's feed speed, effectively extends the service life of the drilling tool, reduces chipping and even breakage during machining, and improves machining efficiency.

[0083] Furthermore, based on the above embodiments, the following, in conjunction with Figure 2 Through specific examples, this paper provides a detailed explanation of the process of calculating the real-time feed rate of the drilling tool during drilling operations using an adjustment algorithm based on real-time power.

[0084] Figure 2 This is a flowchart illustrating a method for calculating the real-time feed rate of a drilling tool during a drilling operation, as provided in Embodiment 2 of this application. Figure 2 As shown, the method includes the following steps:

[0085] S201. Obtain the starting power of the machine tool spindle that drives the drilling tool when the drilling operation starts.

[0086] The starting power of the machine tool spindle when the deep space drill starts drilling is obtained by collecting data through a current sensor.

[0087] S202. Set the power of the computer tool spindle according to the starting power.

[0088] Specifically,

[0089] The set power of the computer tool spindle can be calculated using the following formula:

[0090] Sset = Ps(1+K)

[0091] Where Sser is the set power; Ps is the initial power when the drilling tool contacts the workpiece; K is an empirical coefficient set according to the workpiece material, empirical feed rate and drilling tool size, which is generally a decimal between 0 and 1.

[0092] S203. Based on the set power and real-time power, use the control curve function to calculate the real-time feed rate of the drilling tool during the drilling operation.

[0093] Specifically,

[0094] Calculate the real-time feed rate of the drilling tool during the drilling operation using the following control curve function:

[0095]

[0096] Where Uc is the real-time feed rate; Kp and Kq are adjustment coefficients; Sm is the real-time power of the machine tool spindle, and Sm < Smax, where Smax is the preset maximum power value of the machine tool spindle; and Us is the feed rate control reference offset value.

[0097] In the above embodiments of this application, the initial power of the machine tool spindle driving the drilling tool is obtained when the drilling operation starts, and the set power of the machine tool spindle is calculated based on the initial power. Finally, based on the set power and the real-time power, the real-time feed rate of the drilling tool during the drilling operation is calculated using a control curve function. This prepares for the next step of accurately controlling the real-time feed speed of the drilling tool based on the real-time feed rate.

[0098] It should be noted that the methods of Embodiment 1 or Embodiment 2 described above are more suitable for drilling single workpieces, i.e., workpieces without learning samples. Because single workpieces are unique, the drilling process parameters for each workpiece are almost entirely different; for example, the hole depth and size vary. Therefore, during the drilling process, it is impossible to control the feed rate of the drilling tool based on a fixed learning sample. Thus, the method of this application is more suitable for drilling workpieces without learning samples.

[0099] Drilling multiple workpieces with existing learning samples is typically used for batch production. For example, the machining process of several normal workpieces is usually selected as a reference to obtain the same feature values. A neural network algorithm can then be used to adjust the feed rate of the drilling tool through self-learning. Of course, the method described in this application can also be used for batch drilling of workpieces.

[0105] Obtain the initial power of the machine tool spindle that drives the drilling tool when the drilling operation starts.

[0108] In one possible implementation, the computing module 302 is further used for:

[0109] The set power of the computer tool spindle can be calculated using the following formula:

[0111] Where Sset is the set power; Ps is the initial power when the drilling tool contacts the workpiece; and K is the set coefficient.

[0112] In one possible implementation, the computing module 302 is further used for:
