[0057] The following will clearly describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present application.

[0058] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0059] The following will, with reference to the accompanying drawings, describe in detail the data processing method, workpiece processing method, device and electronic device provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0060] Refer to Figure 1 , Figure 1 which is a flowchart of a data processing method provided by an embodiment of the present application. The method includes:

[0061] Step 101, obtain first detection data of a target workpiece, where the first detection data includes dimension data obtained by detecting the target workpiece;

[0062] Step 102, determine compensation data for processing the target workpiece based on the first detection data;

[0063] Step 103, perform fitting processing on the compensation data to obtain compensation values at N positions on the processing trajectory of the target workpiece, where N is an integer greater than 0;

[0064] Step 104, send the compensation values at the N positions to a processing device, where the compensation values at the N positions are used to adjust the displacement of the grinding wheel in the normal direction at the contact point with the target workpiece and process the target workpiece according to the corresponding compensation values when the grinding wheel of the processing device processes to the N positions.

[0065] Among them, the target workpiece is a workpiece to be processed, and the workpiece can currently be in an unprocessed state or only partially processed state.

[0066] The target workpiece is detected by a detection device to obtain dimension data of the target workpiece. The dimension data can include contour data of the target workpiece. Based on the dimension data, the processing trajectory, compensation data, etc. of the target workpiece can be determined.

[0067] When processing the target workpiece, when the contour of the target workpiece is non-circular, for example, when there are concavities and convexities in the contour, different compensation values are used to compensate the contour of the workpiece at the concave and convex parts. Therefore, the compensation data at these two positions on the contour need to be obtained separately.

[0068] In some embodiments, after obtaining the dimension data of the target workpiece, taking the inverse based on the dimension data of the target workpiece can obtain the compensation data.

[0069] In some embodiments, based on the dimension data of the target workpiece and the target dimension data for processing, determine the data that needs to be compensated for the target workpiece to obtain the compensation data.

[0070] Since the obtained compensation data are multiple discrete data corresponding to multiple positions, fitting processing is performed based on the above compensation data to obtain a compensation value corresponding to any position on the machining trajectory of the outer contour of the target workpiece.

[0071] In some embodiments, the above fitting processing may be to establish a functional relationship between position and compensation value based on multiple compensation data, so as to obtain a compensation value corresponding to any position.

[0072] In some embodiments, the above fitting processing may be to draw a curve based on multiple compensation data, so as to obtain a continuous compensation data curve based on the discrete multiple data.

[0073] Based on the above compensation data curve, a compensation value corresponding to any position on the machining trajectory can be obtained, and the above compensation value is sent to the machining equipment.

[0074] The compensation values at the above N positions may be one or more compensation values among multiple compensation curves obtained according to the compensation curve.

[0075] For example, with the axis of the workpiece as the origin, the circular cross-section of the workpiece is divided into 360°, and each angle (1°, 2°, 3°...) corresponds to a compensation value, obtaining 360 compensation data. Based on the above compensation data for fitting processing, a compensation value corresponding to any angular position can be obtained. For example, the compensation data corresponding to intermediate angular data such as 1.5° and 2.2° can improve the accuracy of obtaining the compensation value, thereby improving the machining accuracy.

[0076] When it is necessary to obtain the compensation data corresponding to any angular position, it can be determined based on the fitted compensation data. In this way, when compensating the workpiece, the machining accuracy can be improved.

[0077] When the grinding wheel of the machining equipment processes to each position, the compensation value corresponding to that position is obtained, and the grinding wheel is moved along the normal direction of the grinding wheel based on the compensation value. During actual compensation, it can be moved along the direction towards the center of the grinding wheel or away from the center of the grinding wheel according to the positive or negative of the compensation value.

[0078] Through the embodiments of the present application, it is possible to process the detection data of the workpiece to obtain the compensation data of each position of the workpiece, so that the machining equipment compensates the workpiece according to the compensation data, which can improve the machining accuracy. And the compensation data obtained by the data fitting method is more complete. When using the above compensation data to adjust the displacement of the grinding wheel to compensate the target workpiece, the machining accuracy of the target workpiece can be further improved.

[0079] Optionally, the compensation data includes M compensation values corresponding to M positions on the machining trajectory of the target workpiece, where M is an integer greater than 0; the fitting process of the compensation data to obtain the compensation values at N positions on the machining trajectory of the target workpiece includes:

[0080] Performing a fitting process on the M compensation values corresponding to the M positions to obtain a compensation curve, where the compensation curve includes the correspondence between the N positions and the N compensation values;

[0081] Obtaining the N compensation values corresponding to the N positions based on the compensation curve.

[0082] Based on the M compensation values corresponding to the M positions, a correspondence between the positions and the compensation values can be established, and a fitting curve can be obtained based on this correspondence.

[0083] In some alternative embodiments, a compensation curve is established with the angle corresponding to the position on the machining trajectory as the abscissa and the compensation value as the ordinate. For example, assuming that the abscissa includes 360 angle values obtained by dividing 360°, and the ordinate includes the corresponding 360 compensation values, performing a fitting process on the compensation values can obtain 720 compensation values corresponding to 720 angles.

[0084] In some alternative embodiments, a compensation curve is established with the position corresponding to the position to be machined on the machining trajectory as the abscissa and the compensation value as the ordinate. For example, assuming that the abscissa corresponds to 100 positions and 100 compensation values. Performing a fitting process on the 100 compensation values can obtain 300 compensation values corresponding to 300 positions.

[0085] In some alternative embodiments, performing a fitting process on the compensation data to obtain a compensation curve around the axis of the target workpiece, where the compensation curve is a curve formed by the N compensation values corresponding to the N positions on the machining trajectory of the target workpiece; obtaining N intersections of the compensation curve and N lines, where the N lines are the lines connecting the axis to the N positions respectively; determining the N compensation values corresponding to the N intersections on the compensation curve as the compensation values at the N positions.

[0086] Through the above method, the compensation value corresponding to any position on the machining trajectory of the target workpiece can be obtained.

[0087] Optionally, the performing a fitting process on the M compensation values corresponding to the M positions to obtain a compensation curve includes:

[0088] Obtain the M angular values corresponding to the M positions on the machining trajectory on the target workpiece, where the M angular values are the angles of rotation of the M lines connecting the M positions to the axis of the target workpiece relative to a reference line, and the reference line is the line connecting a preset reference position on the machining trajectory to the axis;

[0089] Based on the correspondence between the M angular values and the M compensation values, perform a fitting process on the M compensation values to obtain a compensation curve, where the compensation curve includes the correspondence between the N angular values and the N compensation values;

[0090] The obtaining of the N compensation values corresponding to the N positions based on the compensation curve includes:

[0091] Based on the correspondence between the N angular values and the N compensation values, obtain the N compensation values corresponding to the N angular values.

[0092] Obtain the M angular values corresponding to the M positions on the target workpiece, with each position corresponding to one angular value. Taking the line connecting the preset reference position to the axis as the reference line, when the reference line is rotated by the target angle a around the axis, the intersection point A of the rotated reference line and the workpiece arc contour (machining trajectory) is the position A on the workpiece corresponding to the target angle a. In other words, the target angle a is the angle of position A on the workpiece.

[0093] Through the above method, the correspondence between the angle and the position can be obtained. Based on the position-angle correspondence and the correspondence between the position and the compensation value, the correspondence between the angle and the compensation value can be obtained.

[0094] For example, divide 0° to 360° into multiple angles. Taking each angular value as the abscissa and the compensation value corresponding to each angle as the ordinate, a compensation curve extending along the abscissa direction is obtained. Draw a straight line perpendicular to the horizontal axis at the position of 20° on the abscissa. The intersection point of this straight line and the compensation curve is the compensation value of the position on the workpiece corresponding to the angle of 20°.

[0095] Optionally, the M positions include a first position; the obtaining of the M angular values corresponding to the M positions on the machining trajectory includes:

[0096] Obtain the first line connecting the first position on the machining trajectory to the axis;

[0097] Determine the angle value of the rotation of the first line relative to the reference line.

[0098] The positions on the machining trajectory can be represented by angles.

[0099] For example, when the workpiece rotates around its axis in a cylindrical shape, for any position A on the machining trajectory of the cylindrical surface, it can be regarded as the position A on a circular arc in the cross-section. Taking the angle corresponding to the reference line as 0°, when the reference line is rotated around the center of the circle until it intersects with position A, the rotated angle a is the angle value corresponding to position A on the workpiece.

[0100] Through the above method, the angle value corresponding to each position can be obtained, thereby determining the position on the machining trajectory of the workpiece.

[0101] Optionally, before obtaining the first detection data of the target workpiece, the method further includes:

[0102] Setting a reference compensation value;

[0103] The obtaining of the first detection data of the target workpiece includes:

[0104] Obtaining the first detection data after machining the target workpiece. The first detection data is the detection data of the target workpiece obtained after adjusting the displacement of the grinding wheel according to the reference compensation value and machining the target workpiece. The first detection data includes the reference detection data corresponding to the reference compensation value;

[0105] The method further includes:

[0106] Determining the preset reference position of the target workpiece based on the reference detection data.

[0107] Before machining the target workpiece, first set a reference compensation value and use the reference compensation value to machine the target workpiece.

[0108] For example, since during machining, the angle value corresponding to the starting position of machining does not necessarily coincide with the angle corresponding to the above-mentioned reference position, before machining, a compensation value is set at a specific angle position corresponding to the target workpiece. When machining the target workpiece using the data corresponding to this compensation value, based on the shape of the target workpiece obtained after compensation, the actual position where the reference position is located can be determined on the target workpiece.

[0109] After determining the reference position, make the reference position correspond to the reference detection data in the compensation data, so that the accuracy of the data can be improved.

[0110] Optionally, the determining of the compensation data for machining the target workpiece based on the first detection data includes:

[0111] Performing a negation operation on the value of the first detection data to obtain the compensation data for machining the target workpiece.

[0112] After obtaining the detection data of the target workpiece, these data reflect the actual machining deviation or error of the workpiece. According to the required dimensions of the target workpiece, the data to be compensated can be determined, that is, the above-mentioned compensation data.

[0113] Perform an inversion operation based on the detected dimensional data. For example, when the distances from the first position and the second position of the outer contour of the workpiece to the axis are 11 mm and 9 mm respectively, and the machining target for these two positions is 10 mm, during compensation, the compensation value for the first position is -1 mm, and the compensation value for the second position is 1 mm.

[0114] In practical applications, the data obtained after performing the inversion operation on the detection data can be adjusted to meet the compensation requirements of the machining equipment.

[0115] The above data processing method of this embodiment can be applied to a terminal device. After the terminal device processes the data to obtain the compensation value, the compensation value is sent to the machining equipment, and the machining equipment performs compensation based on the compensation value, thereby improving the machining accuracy of the workpiece to solve the problem that the current machining equipment cannot compensate the workpiece.

[0116] And through the above method, the compensation data of the machined workpiece can be obtained, and the cost of the machining equipment can be reduced.

[0117] See Figure 2 , Figure 2 This is a workpiece machining method provided by this application and is applied to a machining equipment. As Figure 2 shown, a workpiece machining method includes:

[0118] Step 201, receive the compensation value sent by the terminal device, where the compensation value is the compensation value of N positions on the machining trajectory of the target workpiece, and the compensation value of the N positions is obtained by fitting the compensation data, and the compensation data is determined based on the detection data of the target workpiece, and N is an integer greater than 0;

[0119] Step 202, when machining the target workpiece to the N positions, adjust the displacement of the grinding wheel in the normal direction at the contact point with the target workpiece according to the compensation value;

[0120] Step 203, machine the target workpiece based on the grinding wheel with the adjusted displacement.

[0121] Based on the compensation value obtained in the above embodiment, the above compensation value is sent to the machining equipment. For example, the compensation data sent by the terminal device is obtained through transmission via the Internet Protocol Interface (IP) interface of the numerical control machine tool. Among them, the above compensation value includes the correspondence between multiple positions and multiple compensation values.

[0122] When the processing equipment processes to any one of the N positions, obtain the corresponding compensation value and adjust the position of the grinding wheel.

[0123] The grinding wheel adjusts its displacement on the X-axis (the axis where the line connecting the contact point and the center of the grinding wheel lies) according to the compensation value until the entire outer contour of the workpiece is compensated.

[0124] Optionally, the compensation values corresponding to the N positions are the compensation values corresponding to the angular values of the N positions on the target workpiece;

[0125] Wherein, the angular value is the angular value of the connection line between each of the N positions and the axis of the target workpiece rotating relative to the reference line, and the reference line is the connection line between the axis and the preset reference position on the processing trajectory.

[0126] The processing equipment can obtain the correspondence between the angular value and the compensation value, and determine the corresponding compensation value based on the angular value.

[0127] When processing to the position corresponding to any angular value of the workpiece, obtain the compensation value corresponding to the angular value of this position. Wherein, the angular value here can be understood as the angle of the connection line between position A on the outer contour (processing trajectory) of the workpiece and the axis rotating relative to the reference line.

[0128] The embodiments of the present application have the following beneficial effects:

[0129] 1) The processing equipment compensates the workpiece by obtaining the compensation value, which can reduce the dependence of the detection system on hardware, improve the detection stability, relieve the maintenance pressure of the later detection system, and improve the product cost performance;

[0130] 2) It can adapt to the detection data output by various measurement and detection devices, and process the detection data through the above data processing method, reducing the difficulty and learning cost of manually processing detection data.

[0131] 3) It can adapt to the grinding scenarios of various workpieces including standard contours and free contours, and can automatically output the adapted compensation data points to the compensation positions according to the compensation method according to the shape of the grinding contour.

[0132] To facilitate further understanding of this embodiment, the following is an example in combination with specific implementation manners.

[0133] As Figure 3 shown, the workpiece processing method includes the following processes:

[0134] Step 1: Through parameter setting, input the correct dimensions of the workpiece contour, draw the basic contour and check whether the contour is correct.

[0135] Step 2: Based on the cutting cycle settings and non-cutting parameter settings, implement the parameter input of the machining trajectory.

[0136] Step 3: Turn on the compensation function, set the reference compensation parameters, and use the position corresponding to 60 degrees as the reference position.

[0137] Step 4: Based on Steps 2 and 3 above, generate the machining trajectory to obtain the compensation values corresponding to the respective angle values of the workpiece. Check whether the trajectory is correct. If it is correct, proceed to the next step; otherwise, go back to Step 2 to reset the parameters.

[0138] Step 5: Output the Numerical Control (NC) code for the generated machining trajectory, input the NC code into the machining equipment for machining, and perform inspection and measurement after machining is completed.

[0139] Step 6: Check the inspection data, find the position corresponding to the highest grinding point obtained based on the settings of the reference position, align this position with the reference position corresponding to 60 degrees, based on the reference position.

[0140] Step 7: Turn on the compensation function again, import the data obtained in Step 6 into the compensation module, and determine the compensation values corresponding to the respective angles.

[0141] Step 8: Regenerate the machining trajectory based on the data after angle alignment, and output the corresponding NC code for the machining trajectory. Use the NC code to input into the machining equipment for machining.

[0142] Step 9: Perform inspection and measurement on the machined workpiece, check the change in machining accuracy and whether it is within the qualified range. If it is unqualified, go back to Step 7 to perform compensation settings for machining new workpieces until it is adjusted to the qualified range.

[0143] Step 10: If it is qualified, end the adjustment and enter the batch machining mode.

[0144] In the above process, after obtaining the inspection data of the workpiece, perform data processing on the inspection data to obtain compensation data.

[0145] As Figure 4 shown, the method for processing based on the inspection data includes the following steps:

[0146] Step 1: Through reference setting, artificially set a reference compensation point at a specified angle and add it to the machining NC. Use this data for machining to obtain the machined workpiece.

[0147] Step 2: After machining is completed, perform inspection on the workpiece using a measuring instrument and output the inspection data. The inspection data may include dimensional data based on the angle of the workpiece. Here, the division and measurement order of the angles are not limited.

[0148] Step 3: Import the above detection data, analyze the highest compensation point in the detection data, which is obtained by setting the reference compensation data. After finding this point, correspond it to the angular position of the initial reference compensation to achieve re - sorting and processing of the entire detection data.

[0149] Step 4: Perform an inversion operation on the detection data to obtain the compensation data for the corresponding angles.

[0150] Step 5: Perform a fitting process on the above - mentioned compensation data to obtain the corresponding relationship between the angles and the compensation data, and generate a machining trajectory.

[0151] Step 6: Based on the angular division of the trajectory calculation, respectively obtain the intersection values of the corresponding angles and the compensation curve and save them. For example, taking each angle corresponding to 0° to 360° of the workpiece as the X - coordinate and the compensation value as the Y - coordinate, generate a compensation curve. For any angle on the abscissa, the corresponding compensation value can be obtained.

[0152] Step 13: Recalculate the trajectory, calculate the trajectory contact points at each angle, inversely calculate the corresponding angle values according to the positions of the contact points, and then extract the corresponding compensation values from the compensation data.

[0153] Step 16: Add the extracted compensation values to the normal direction of the line connecting the corresponding contact points and the center of the grinding wheel, and then adjust the displacement of the grinding wheel on the X - axis until the entire contour compensation is completed.

[0154] Step 19: After the calculation is completed, output the compensated NC machining program for on - machine machining.

[0155] Step 22: Perform inspection after machining, and judge whether re - compensation processing is required according to the inspection results. If compensation is required, re - enter Step 1, otherwise end.

[0156] In the related art, by configuring a measuring instrument on the machine tool, calling the measuring instrument for in - machine inspection after machining, then processing the compensated data and adjusting the original machining NC program, and re - machining, the accuracy of the machining contour is ensured through repeated iteration. However, this solution has a high hardware cost for the machining equipment. After configuring the measuring instrument, the cost of the machine tool will increase significantly, and requirements for the model of the CNC system and the compensation function are needed, which is not convenient for maintenance.
