Description

Technical Field

[0001] This application relates to the field of grinding control technology, and particularly to a method, system, device and medium for grinding wheel thickness management. Background Art

[0002] During the use of a grinding wheel for grinding, since the thickness of the grinding wheel is closely related to its remaining life, it is necessary to monitor the thickness change of the grinding wheel in real time. When the compensation amount reaches the threshold after automatic or manual compensation of the grinding wheel thickness, it indicates that the service life of the grinding wheel has been reached. At this time, an alarm mechanism is triggered to remind to replace the grinding wheel. However, the existing method for monitoring the grinding wheel thickness is to set a fixed alarm threshold as the alarm trigger condition for the compensation amount. However, since the thickness of the grinding wheel gradually decreases after each dressing compensation, based on the new grinding wheel thickness, the corresponding alarm threshold should be adjusted accordingly. However, if a fixed alarm threshold is used, it is difficult to accurately predict the remaining life of the grinding wheel, which easily leads to workpiece out-of-tolerance due to excessive wear of the grinding wheel. Summary of the Invention

[0015] Determine whether the actual upper limit value of the thickness is less than or equal to the dynamic alarm threshold. If so, send an alarm message. If not, return to obtaining the cumulative compensation amount and the average compensation amount after each dressing compensation of the target grinding wheel according to the initial thickness.

[0016] Optionally, the expression of the attenuation correction model is:

[0017] T max =T·e -λ·N ;

[0018] In the formula, T max is the actual upper limit value of the thickness, T is the initial thickness, e is the natural constant, λ is the attenuation coefficient, and N is the cumulative dressing compensation times.

[0021] Determine whether the wear rate V is greater than a preset safety warning value. If so, reduce the dynamic alarm threshold by 5% - 10%. If not, proceed to the next step.

[0023] In the formula, C 总 is the cumulative compensation amount, N is the cumulative dressing compensation times, Z i is the compensation amount for the i-th automatic dressing compensation, and S i is the compensation amount for the i-th manual dressing compensation;

[0024] C 平 =C 总 / N;

[0025] In the formula, C 平 is the average compensation amount.

[0026] Optionally, the expression of Z i is:

[0027] Z i =K·ΔT;

[0036] The beneficial effects that the present application can achieve are as follows:

[0037] This application first obtains basic data such as the initial thickness and initial alarm threshold of the target grinding wheel. According to the initial thickness, the cumulative compensation amount and average compensation amount after each dressing compensation of the target grinding wheel can be obtained. Since the average compensation amount obtained after each dressing compensation is dynamically changing, the basic parameters of the initial alarm threshold and the dynamic parameters of the average compensation amount are jointly input into a preset threshold dynamic adjustment model, and the initial alarm threshold can be dynamically adjusted, so as to calculate the dynamically changing dynamic alarm threshold. When the cumulative compensation amount of the target grinding wheel in the current dressing compensation cycle is greater than or equal to the dynamic alarm threshold, it indicates that the service life of the grinding wheel has been reached. At this time, an alarm message is sent to notify the management personnel to replace the grinding wheel in time. To sum up, this application can dynamically calculate the corresponding dynamic alarm threshold based on the threshold dynamic adjustment model, so as to flexibly adapt to the thickness parameter changes after each dressing compensation of the grinding wheel, accurately predict the remaining life of the grinding wheel, and reduce the risk of workpiece out-of-tolerance caused by excessive wear of the grinding wheel.

[0047] Embodiment 1

[0048] Refer to Figure 1 , Figure 1 is a schematic structural diagram of a computer device for the hardware operating environment involved in the solution of this embodiment. As Figure 1As shown in the figure, the computer device may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wireless-Fidelity (WI-FI) interface). The memory 1005 may be a high-speed Random Access Memory (RAM) or a stable Non-Volatile Memory (NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0049] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the computer device, and it may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements.

[0050] As Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and an electronic program.

[0051] In Figure 1 the computer device shown in the figure, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the computer device of this embodiment may be set in the computer device, and the computer device calls the grinding wheel thickness management system stored in the memory 1005 through the processor 1001 and executes the grinding wheel thickness management method provided in this embodiment.

[0052] Referring to Figure 2 , based on the aforementioned hardware environment, this embodiment provides a grinding wheel thickness management method, including the following steps:

[0053] Obtain the initial thickness and the initial alarm threshold of the target grinding wheel;

[0054] According to the initial thickness, obtain the cumulative compensation amount and the average compensation amount of the target grinding wheel after each dressing compensation;

[0055] Input the initial alarm threshold and the average compensation amount into a preset threshold dynamic adjustment model to obtain a dynamic alarm threshold;

[0056] Determine whether the cumulative compensation amount of the target grinding wheel in the current dressing compensation cycle is greater than or equal to the dynamic alarm threshold. If so, send an alarm message; if not, return to obtaining the cumulative compensation amount and the average compensation amount of the target grinding wheel after each dressing compensation according to the initial thickness.

[0057] In this embodiment, basic data such as the initial thickness and the initial alarm threshold of the target grinding wheel are first obtained. According to the initial thickness, the cumulative compensation amount and the average compensation amount of the target grinding wheel after each dressing compensation can be obtained. Since the average compensation amount obtained after each dressing compensation is dynamically changing, the basic parameter of the initial alarm threshold and the dynamic parameter of the average compensation amount are jointly input into a preset threshold dynamic adjustment model, so that the initial alarm threshold can be dynamically adjusted, and thus the dynamically changing dynamic alarm threshold can be calculated. When the cumulative compensation amount of the target grinding wheel in the current dressing compensation cycle is greater than or equal to the dynamic alarm threshold, it indicates that the service life of the grinding wheel has been reached. At this time, an alarm message is sent to notify the management staff to replace the grinding wheel in time. To sum up, based on the threshold dynamic adjustment model, this embodiment can dynamically calculate the corresponding dynamic alarm threshold, so as to flexibly adapt to the thickness parameter changes of the grinding wheel after each dressing compensation, accurately predict the remaining life of the grinding wheel, and reduce the risk of workpiece out-of-tolerance caused by excessive wear of the grinding wheel.

[0058] It should be noted that the setting of the initial alarm threshold here is related to the initial thickness of the target grinding wheel. Let the initial alarm threshold be C and the initial thickness be T, and its expression is C = δ·T, where δ is a safety factor, and the value of the correlation coefficient δ is related to the material of the grinding wheel (for example, 1 / 3 for resin grinding wheels and 1 / 4 for diamond grinding wheels). All kinds of information data of the grinding wheel are stored in the power-off holding area. Even if the grinding machine is powered off and then powered on again, all data can be restored; when the alarm message is triggered and the manipulator returns to the initial feeding position, the equipment stops and waits for the operator to replace the new grinding wheel.

[0059] As an optional implementation manner, the expression of the threshold dynamic adjustment model is:

[0060] C' = C - α·Q' + β·S;

[0061] In the formula, C' is the dynamic alarm threshold, C is the initial alarm threshold, α is the wear influence factor, Q' is the average compensation amount, β is the manual compensation weight value, and S is the manual compensation value.

[0062] In this embodiment, since the average compensation amount after each dressing compensation changes to a certain extent, and a wear influence factor α is introduced at the same time. This wear influence factor α can characterize the adjustment coefficient of each compensation amount to the threshold value (generally taken as 0.1 - 0.5). Considering the situation of manual intervention for correction compensation each time, a manual compensation value S and a manual compensation weight value β (generally taken as 0.1 - 0.2) are also introduced here. When there is no manual intervention, then β·S = 0. Based on the above formula, the dynamic adjustment of the initial alarm threshold can be realized, so as to accurately calculate the corresponding dynamic alarm threshold after each compensation.

[0063] As an alternative embodiment, if it is determined that the cumulative compensation amount of the target grinding wheel in the current dressing compensation cycle is less than the dynamic alarm threshold, it further includes:

[0064] Obtain the cumulative dressing compensation times of the target grinding wheel;

[0065] Input the cumulative dressing compensation times and the initial thickness into a preset attenuation correction model to obtain the upper limit value of the actual thickness of the target grinding wheel;

[0066] Judge whether the upper limit value of the actual thickness is less than or equal to the dynamic alarm threshold. If so, send an alarm message. If not, return to obtaining the cumulative compensation amount and the average compensation amount of the target grinding wheel after each dressing compensation according to the initial thickness.

[0067] In this embodiment, since each time the grinding wheel is dressed and compensated, the base material of the grinding wheel will be reduced due to loss, that is, the upper limit value of the actual thickness will decrease with the increase of the compensation times. Therefore, when the cumulative compensation amount of the target grinding wheel in the current dressing compensation cycle is less than the dynamic alarm threshold, in order to further improve the prediction accuracy of the remaining grinding wheel life, an attenuation correction model is introduced here. Inputting the cumulative dressing compensation times and the initial thickness into this attenuation correction model, the upper limit value of the actual thickness can be calculated. The upper limit value of the actual thickness represents the maximum available thickness that the grinding wheel can still maintain after multiple dressing compensations, and is generally affected by the dressing times and material attenuation. Therefore, when it is calculated that the upper limit value of the actual thickness is less than or equal to the dynamic alarm threshold, an alarm can also be triggered, further improving the safety.

[0068] As an alternative embodiment, the expression of the attenuation correction model is:

[0069] T max =T·e -λ·N ;

[0070] In the formula, T max is the upper limit value of the actual thickness, T is the initial thickness, e is the natural constant (taken as 2.7), λ is the attenuation coefficient, and N is the cumulative dressing compensation times.

[0071] In this embodiment, based on the above formula, after inputting the initial thickness T and the cumulative dressing compensation times N, for example, T = 30 mm, N = 5, and λ is taken as 0.02, then T max = 30·e -0.02·5 ≈ 27.14 mm. The more the cumulative dressing compensation times N are, the lower the actual upper limit value of the thickness is. The calculation is reliable and has strong reference and guiding significance.

[0072] As an alternative embodiment, after inputting the initial alarm threshold and the average compensation amount into a preset threshold dynamic adjustment model to obtain the dynamic alarm threshold, it further includes:

[0073] Obtaining the wear rate V of the target grinding wheel after dressing compensation in the current round; where V = Q' / t, and t is the time of a single grinding cycle;

[0074] Judging whether the wear rate V is greater than a preset safety warning value. If so, reducing the dynamic alarm threshold by 5% - 10%. If not, proceeding to the next step.

[0075] In this embodiment, to improve the adjustment accuracy of the dynamic alarm threshold, the influence of the wear rate V of the target grinding wheel is also considered here. The wear rate V can be calculated by the ratio of the average compensation amount to the time of a single grinding cycle. When the wear rate V is too fast, it means that the consumption speed of the grinding wheel service life is faster than expected. Here, a safety warning value is set. If the wear rate V is greater than this safety warning value, the dynamic alarm threshold calculated by the threshold dynamic adjustment model will be further reduced by 5% - 10% to obtain a new dynamic alarm threshold, and then proceed to the next step (i.e., judging whether the cumulative compensation amount is equal to the dynamic alarm threshold). Otherwise, directly proceed to the next step. Therefore, the dynamic alarm threshold can be adaptively corrected by the wear rate V here, further improving the prediction accuracy of the grinding wheel service life.

[0076] As an alternative embodiment, the expressions for the cumulative compensation amount and the average compensation amount are respectively:

[0077] In the formula, C 总 is the cumulative compensation amount, N is the cumulative dressing compensation times, Z i is the compensation amount for the i-th automatic dressing compensation, and S i is the compensation amount for the i-th manual dressing compensation;

[0078] C 平 = C 总 / N;

[0079] In the formula, C 平 is the average compensation amount.

[0080] In this embodiment, the cumulative compensation amount is the sum of the compensation amounts of multiple dressing compensations. When calculating the cumulative compensation amount, both automatic compensation and manual compensation methods are taken into account. If both compensation methods exist, the total sum of the compensation amounts of both is measured simultaneously. If only one of the compensation methods is adopted, only the total sum of the compensation amounts of that compensation method needs to be measured. The average compensation amount is the ratio of the cumulative compensation amount to the cumulative number of dressing compensations, and the calculation is reliable, ensuring the validity of the data.

[0081] As an alternative embodiment, the expression of Z i is:

[0082] Z i = K·ΔT;

[0083] K is the compensation coefficient, which is set according to the type of the target grinding wheel, and ΔT is the thickness change amount of the target grinding wheel.

[0084] In this embodiment, when calculating the automatic compensation amount, based on the above formula, with the thickness change amount ΔT (i.e., the thickness wear amount of the grinding wheel during the wear process) as the leading parameter factor, and introducing the compensation coefficient K for correction, the value of the corresponding automatic compensation amount can be calculated.
