Specifically, the specific working principle of the above-mentioned management and control system 10 for numerical control machining and detection can be referred to the following text description about the management and control method for numerical control machining and detection.

Referring to fig. 6, fig. 6 is a flowchart illustrating a method for managing and controlling numerical control machining and detection according to an embodiment of the present disclosure; in the present embodiment, a management and control method for numerical control machining and detection is provided, which can be specifically executed by the management and control system 10 for numerical control machining and detection; the method specifically comprises the following steps:

step S11: the production management and control device determines the machine tool according to the workpiece processing work order instruction and calls the corresponding detection probe, the calibration ball and/or the cutter of the machine tool from the detection equipment in the numerical control machine control module so as to be installed on the machine tool.

Specifically, the production control device 14 receives a workpiece processing work order instruction of a workpiece to be processed issued by a user; then the production management and control device 14 acquires the current states and specifications of all the machine tools 21 and the information of the tools and the detection probes 41 of the machine tools from the data storage device 13, and automatically determines the machine tools 21 according to the received work order instructions for processing the workpiece, the current states and specifications of all the machine tools 21 and the information of the tools and the detection probes 41 of the machine tools; then, the production management and control device 14 calls the corresponding tool, the detection probe 41 and the calibration ball 42 of the machine tool from the detection device in the numerical control machine control device 11 to be installed on the machine tool 21, and simultaneously issues the workpiece processing work order instruction to the data collector 120 corresponding to the current machine tool 21, and after the current machine tool 21 receives the instruction of the data collector 120, waits for the work order to carry out formal processing and detection.

In a specific embodiment, the process of retrieving the corresponding tool, the detection probe 41 and the calibration ball 42 of the machine tool from the detection device by the production management and control device 14 further includes sending parameter information data of the machine tool 21 to the tool management device 17, and the tool management device 17 retrieves the corresponding tool, the detection probe 41 and the calibration ball 42 of the machine tool according to the parameter information data of the machine tool 21 to install on the machine tool 21.

Specifically, when a work order for processing a workpiece is started, the production control device 14 determines the size and the type of the detection probe 41, the calibration ball 42 and/or the tool of the machine tool according to the processing process information of the workpiece, analyzes the running states of all the machine tools 21 in the workshop through the industrial data stored in the data storage device 13, and allocates the most appropriate machine tool 21 to perform automatic production scheduling of the work order; then, cleaning the machine stations of the machine tool 21 distributed by the work order, and clamping and positioning the workpiece; and simultaneously clamping and fixing the detection probe 41, the calibration ball 42 and/or a tool of the machine tool called from the detection equipment.

The calibration ball 42 may be made of a super-hard ceramic material, and has high toughness, high strength, high hardness, high wear resistance, good corrosion resistance, good insulating property, and static electricity resistance, and is periodically replaced.

Step S12: and the controller in the numerical control machine tool control device switches the detection probe to a processing main shaft of the machine tool, and detects the calibration ball by using the detection probe according to the input first detection program so as to obtain the abrasion error value of the detection probe.

Specifically, referring to fig. 7, fig. 7 is a sub-flowchart of step S12 in fig. 6; step S12 specifically includes:

step S121: and a controller in the numerical control machine tool control device switches the detection probe to a processing spindle of the machine tool.

Step S122: the production control device calls a first detection program from the data storage device according to the preset detection point of the calibration ball, and sends the first detection program to a controller corresponding to the machine tool through the data acquisition device.

Specifically, the preset detection points of the calibration ball 42 are automatically generated according to the number of the preset detection points of the calibration ball 42 and the type of the machine tool 21, then the corresponding first detection program is generated according to the preset detection points of the calibration ball 42, when the preset detection points on the calibration ball 42 need to be detected, the first detection program is called from the data storage device 13, and the first detection program is sent to the controller corresponding to the machine tool 21 through the data collector 120 corresponding to the machine tool 21 in the data collection device 12.

Step S123: the controller detects the plurality of preset detection points of the calibration ball by using the detection probe according to the input first detection program to obtain the measured data of each preset detection point of the calibration ball.

Specifically, the first position of the detection probe 41 contacts one of the preset detection points in the calibration ball 42, and the current preset detection point of the calibration ball 42 is automatically detected under a first detection program, and actual measurement data of the current preset detection point of the calibration ball 42 is obtained; then, a second position of the detecting probe 41, which is different from the first position, is brought into contact with another preset detecting point of the calibration ball 42 and detected to obtain measured data corresponding to another preset detecting point of the calibration ball 42, and the above steps are repeated until the detecting probe 41 detects all the preset detecting points on the calibration ball 42. The contact position between the detecting probe 41 and the calibration ball 42 is a detecting point on the detecting probe 41, and it can be understood that a plurality of detecting points on the detecting probe 41 correspond to a plurality of preset detecting points on the calibration ball 42 one to one.

Step S124: and the production control device calculates and acquires the abrasion error value of each detection point of the detection probe according to the actual measurement data of each preset detection point of the calibration ball and the theoretical detection data of each preset detection point of the calibration ball.

Specifically, each preset detection point of the calibration ball 42 corresponds to a theoretical detection data, and in the specific implementation process, the difference between the actual measurement data of each preset detection point of the calibration ball 42 and the theoretical detection data of the corresponding preset detection point of the calibration ball 42 is obtained by comparing the actual measurement data with the theoretical detection data to obtain the difference, which is the wear error value of the detection point corresponding to the detection probe 41. Specifically, the measured data and the theoretical detection data corresponding to each preset detection point of the calibration ball 42 may be three-dimensional coordinate data, which is taken as an example in the following embodiments.

Specifically, the wear error value of the detection point of the detection probe 41 specifically refers to an error value of the detection point of the detection probe 41 in three directions.

Specifically, each preset detection point of the calibration ball 42 and the corresponding theoretical detection data thereof may be automatically generated according to the parameters input by the user and stored in the data storage device 13.

The following description will be made in detail with reference to a specific embodiment.

For example, referring to fig. 8, fig. 8 is a schematic diagram illustrating a contact position between a detection probe and a calibration ball according to an embodiment of the present application; the calibration ball 42 is provided with two preset detection points, namely a preset detection point A1 and a preset detection point A2, the detection point of the detection probe 41 contacting with the preset detection point A1 is B1, and the detection point contacting with the preset detection point A2 is B2; wherein, the theoretical detection data corresponding to the first predetermined detection point A1 is (X)₀，Y₀，Z₀) The actual measurement data detected by the detection probe 41 is (X)₁，Y₁，Z₁) The second predetermined detection point A2 corresponds to the theoretical detection data of (X)₂，Y₂，Z₂) The actual measurement data detected by the detection probe 41 is (X)₃，Y₃，Z₃) (ii) a The abrasion error value at the detection point B1 of the detecting probe 41 is (X)_δ1、Y_δ1、Z_δ1) Wherein X is_δ1＝X₀-X₁，Y_δ1＝Y₀-Y₁，Z_δ1＝Z₀-Z₁The wear error value at the detection point B2 of the detection probe 41 is (X)_δ2、Y_δ2、Z_δ2) Wherein X is_δ1＝X₃-X₂，Y_δ1＝Y₃-Y₂，Z_δ1＝Z₃-Z₂。

Step S13: the controller switches the tool of the machine tool to the machining spindle of the machine tool, and drives the machine tool to machine the workpiece with the tool of the machine tool according to the input first machining program.

Specifically, a tool of the machine tool is clamped and fixed on a processing spindle of the machine tool 21, the production control device 14 calls a first processing program (for example, a G code file) of the workpiece from the data storage device 13 according to the processing process information of the workpiece, and sends an instruction to the data collector 120 and the controller corresponding to the machine tool 21 through the data collection device 12; the controller drives the machine tool 21 to machine the workpiece by calling a first machining program (for example, a G code file) to obtain a machined file.

Step S14: the controller switches the detection probe to a machining main shaft of the machine tool, and utilizes the detection probe to perform on-machine detection on the machined workpiece according to the input second detection program so as to acquire measured data of the machined workpiece.

Specifically, after the machined workpiece 43 is obtained, a key detection position influencing the size of the workpiece is selected as a preset detection point of the machined workpiece 43 according to the machining track of the workpiece, then, a corresponding second detection program (for example, a G code file) is generated according to the preset detection points of the processed workpiece 43, when the machined workpiece 43 needs to be inspected, the production management and control device 14 calls the second inspection program from the data storage device 13, and sends the second detection program to the controller corresponding to the machine tool 21 through the data collector 120 corresponding to the machine tool 21 in the data collection device 12, so that the controller performs on-machine detection on the workpiece according to the input second detection program, thereby obtaining the actual measurement data of each preset detection point of the workpiece, and at the same time, the actual measurement data of each preset detection point of the workpiece is transmitted to the data storage device 13 through the data collector 120.

Specifically, during the process of detecting the machined workpiece 43, each detection point of the detection probe 41 is contacted with each preset detection point on the workpiece, so as to obtain the measured data of each preset detection point of the workpiece. Specifically, both the actual measurement data of the machined workpiece 43 detected by the detection probe 41 and the theoretical detection data of the machined workpiece 43 may be three-dimensional coordinate data, and this is taken as an example in the following embodiments.

Step S15: the data acquisition device acquires parameter information data of the machine tool, a wear error value of the detection probe and actual measurement data of the machined workpiece, and stores the parameter information data of the machine tool, the wear error value of the detection probe and the actual measurement data of the machined workpiece in the data storage device.

Step S16: the production control device analyzes and processes theoretical detection data of the processed workpiece, the abrasion error value of the detection probe and actual measurement data of the processed workpiece.

Wherein, the theoretical detection data of the processed workpiece 43 is the preset detection data of the final finished product of the workpiece; the actual measurement data is detection data of the workpiece 43 after machining detected by the detection probe 41.

Specifically, the production control device 14 analyzes theoretical detection data of the processed workpiece 43, the wear error value of the detection probe 41, and actual measurement data of the processed workpiece 43 to determine whether the current workpiece is qualified for processing, and when the determination result is qualified, takes down the workpiece, and counts the working time performance, the cost accounting, collects processing detection data, and maintains the equipment machine and the tool according to the data stored in the data storage device 13; when the judgment result is unqualified and the judgment result is not over-cut, the workpiece is reprocessed until the requirement of a work order is met or the over-cut is met, then the workpiece is taken down, the working hour performance, the cost accounting and the processing detection data are counted according to the data stored in the data storage device 13, and equipment tables, cutters and the like are maintained; and when the judgment result is unqualified and the workpiece is over-cut, directly taking down the workpiece, counting the work-hour performance, carrying out cost accounting, collecting processing detection data, maintaining equipment tables, cutters and the like according to the data stored in the data storage device 13. Specifically, the production control device 14 calculates the work time performance, the cost accounting, the quality record, and the maintenance of the machine tool 21 based on the parameter information data and the like of the machine tool 21 stored in the data storage device 13.

Whether the machined workpiece 43 is over-cut specifically means whether the data such as the size, the angle and the like of the machined workpiece 43 are smaller than a preset threshold value; for example, a workpiece with a length of 5cm and a width of 3cm is pre-processed, and if the actually processed workpiece 43 has a length of 4cm and a width of 3cm, it is determined that the processed workpiece 43 is over-cut; if the length of the actually processed workpiece 43 is 6cm and the width thereof is 3cm, it is determined that the processed workpiece 43 is not over-cut (i.e., not over-cut), and it may be further processed to satisfy a preset condition.

In the management and control method for the numerical control machining and detection provided by the embodiment, the production management and control device 14 determines the machine tool 21 according to the workpiece machining work order instruction and calls the corresponding detection probe 41, calibration ball 42 and/or the tool of the machine tool from the detection equipment in the numerical control machine 11 to install on the machine tool 21; then, the detection probe 41 is switched to the processing spindle of the machine tool 21 by the controller in the numerical control machine tool control device 11, and the calibration ball 42 is detected by the detection probe 41 according to the input first detection program to obtain the wear error value of the detection probe 41; then the controller switches the tool of the machine tool to the processing spindle of the machine tool 21, and drives the machine tool 21 to process the workpiece by using the tool of the machine tool according to the input first processing program to obtain a processed workpiece 43; then the controller switches the detection probe 41 to the processing spindle of the machine tool 21, and performs on-machine detection on the processed workpiece 43 by using the detection probe 41 according to the input second detection program to acquire actual measurement data of the processed workpiece 43; the data acquisition device 12 acquires parameter information data of the machine tool 21, a wear error value of the detection probe 41, and actual measurement data of the machined workpiece 43, and stores the parameter information data of the machine tool 21, the wear error value of the detection probe 41, and the actual measurement data of the machined workpiece 43 in the data storage device 13; the production control device 14 analyzes and processes theoretical detection data of the processed workpiece 43, the wear error value of the detection probe 41, and actual measurement data of the processed workpiece 43, so that not only can the processing and on-machine detection of the workpiece be realized, but also the workpiece can be monitored and managed in real time, and simultaneously all machine tools 21 in the whole workshop can be monitored and managed in real time.

Specifically, the specific implementation process of the steps S21 to S25 is the same as or similar to the specific implementation process of the steps S11 to S15 in the numerical control machining and detecting control method provided in the foregoing embodiment, and the same or similar technical effects can be achieved.

Step S26: the production control device judges whether the processed workpiece is qualified or not according to theoretical detection data of the processed workpiece, the abrasion error value of the detection probe and actual measurement data of the processed workpiece.

Specifically, when the determination result is qualified, step S29 is executed; when the determination result is not good, step S27 is executed.

Step S27: and judging whether the processed workpiece is over-cut or not.

Specifically, when the determination result is the over-cut, it is determined that the processed workpiece 43 is not qualified, and step S29 is executed; when the judgment result is that there is no over-cut, step S28 is executed.

Compared with the numerical control machining and detection control method provided by the embodiment, the method for controlling numerical control machining and detection further comprises the steps of judging whether the machined workpiece 43 is qualified or not by the production control device 14 according to theoretical detection data of the machined workpiece 43 stored by the data storage device 13, the abrasion error value of the detection probe 41 and actual measurement data of the machined workpiece 43, switching the detection probe 41 to the machining spindle of the machine tool 21 by the controller when the workpiece is unqualified in machining and not over-cut, driving the machine tool 21 to re-machine the machined workpiece 43 by using the cutter of the machine tool according to an input compensation machining program until the machined workpiece is qualified or over-cut, so as to realize on-machine detection and machining of the workpiece; then, the production management and control device 14 counts the working hour performance, the cost accounting, the quality recording, the maintenance of the machine tool 21 and the like according to the parameter information data of the machine tool 21 and displays the results on the display unit 124, so that the workers can check and process the results in time, and then real-time monitoring and management of numerical control machining and detection are realized.

Referring to fig. 10, fig. 10 is a flowchart illustrating a method for managing and controlling numerical control machining and detection according to another embodiment of the present disclosure; in the present embodiment, a management and control method for numerical control machining and detection is provided, which can be specifically executed by the management and control system 10 for numerical control machining and detection; specifically, the method may comprise:

step S31: the production management and control device determines the machine tool according to the workpiece processing work order instruction and calls a corresponding detection probe, a calibration ball and/or a cutter of the machine tool from detection equipment in the numerical control machine tool control device so as to be installed on the machine tool.

Step S32: and the controller in the numerical control machine tool control device switches the detection probe to a processing main shaft of the machine tool, and detects the calibration ball by using the detection probe according to the input first detection program so as to obtain the abrasion error value of the detection probe.

Step S33: the controller switches the tool of the machine tool to the machining spindle of the machine tool, and drives the machine tool to machine the workpiece with the tool of the machine tool according to the input first machining program.

Step S34: the controller switches the detection probe to a machining main shaft of the machine tool, and utilizes the detection probe to perform on-machine detection on the machined workpiece according to the input second detection program so as to acquire measured data of the machined workpiece.

Step S35: the data acquisition device acquires parameter information data of the machine tool, a wear error value of the detection probe and actual measurement data of the machined workpiece, and stores the parameter information data of the machine tool, the wear error value of the detection probe and the actual measurement data of the machined workpiece in the data storage device.

Specifically, the specific implementation process of the steps S31 to S35 is the same as or similar to the specific implementation process of the steps S21 to S25 in the management and control system for numerical control machining and detection provided in the above embodiment, and the same or similar technical effects can be achieved.

Step S36: and the production control device calculates and acquires final error values of all preset detection points of the processed workpiece according to the wear error values of all detection points of the detection probe, the actual measurement data of the processed workpiece and the theoretical detection data of the processed workpiece.

Specifically, the real-time detection data of each preset detection point of the processed workpiece 43 is obtained according to the actual measurement data of each preset detection point of the processed workpiece 43 detected by the detection probe 41 and the wear error corresponding to each detection point of the detection probe 41, and then the real-time detection data of each preset detection point of the processed workpiece 43 is compared with the corresponding theoretical detection data to obtain a difference value therebetween, where the difference value is a final error value of the corresponding preset detection point on the processed workpiece 43. The real-time detection data of each preset detection point of the machined workpiece 43 is corresponding detection data when the detection point of the detection probe 41 is not worn.

It can be understood that, when the detection probe 41 detects the processed workpiece 43, data detected by the detection probe 41 is obtained, and the data is measured data; however, since there may be wear at the detection points of the detection probe 41, when acquiring real-time detection data of the processed workpiece 43, the data that should be actually detected by the processed workpiece 43, that is, the real-time detection data corresponding to the preset detection point of the processed workpiece 43, should be obtained by adding a wear error value of the corresponding detection point to the actual measurement data detected by the detection probe 41.

The process is illustrated below: for example, referring to fig. 11, fig. 11 is a schematic view illustrating a contact position between a detection probe and a processed workpiece according to an embodiment of the present disclosure; the machined workpiece 43 includes two preset detection points, namely a preset detection point C1 and a preset detection point C2; when the detection probe 41 detects the machined workpiece 43, the detection point B1 of the detection probe 41 contacts and detects the preset detection point C1 on the machined workpiece 43, and the preset detection of the machined workpiece 43 is obtainedThe measured data at the point C1 is (X)₄、Y₄、Z₄) If there is no wear at the detection point B1 of the detection probe 41, the real-time detection data corresponding to the preset detection point C1 of the processed workpiece 43 is (X)₄、Y₄、Z₄) (ii) a If there is wear at the probing point B1 of the probing tip 41, the wear error value is (X)_δ1、Y_δ1、Z_δ1) The real-time detection data corresponding to the preset detection point C1 of the processed workpiece 43 is (X)₅、Y₅、Z₅) Wherein X is₅＝X₄+X_δ1，X₅＝Y₄+Y_δ1，X₅＝Z₄+Z_δ1(ii) a The detection point B2 of the detection probe 41 is contacted with the preset detection point C2 on the workpiece and detected, and the obtained actual measurement data at the preset detection point C2 of the workpiece is (X)₆、Y₆、Z₆) If there is no wear at the detection point B2 of the detection probe 41, the real-time detection data corresponding to the preset detection point C2 of the processed workpiece 43 is (X)₆、Y₆、Z₆) (ii) a If there is wear at the detecting point B2 of the detecting probe 41, and the wear error value corresponding to the detecting point B2 of the detecting probe 41 is (X)_δ2、Y_δ2、Z_δ2) If the preset detection point C2 of the workpiece corresponds to the real-time detection data (X)₇、Y₇、Z₇) Wherein X is₇＝X₆+X_δ2，Y₇＝Y₆+Y_δ2，Z₇＝Z₆+Z_δ2. Wherein, if the theoretical detection data corresponding to the preset detection point C1 of the processed workpiece 43 is (X)₈、Y₈、Z₈) The theoretical detection data corresponding to the preset detection point C2 of the machined workpiece 43 is (X)₉、Y₉、Z₉) The final error value corresponding to the predetermined detection point C1 of the processed workpiece 43 is (X)₁₀、Y₁₀、Z₁₀) Wherein X is₁₀＝X₄+X_δ1-X₈，X₁₀＝Y₄+Y_δ1-Y₈，X₁₀＝Z₄+Z_δ1-Z₈(ii) a Presetting of workpiecesThe final error value corresponding to the detection point C2 is (X)₁₀、Y₁₀、Z₁₀) Wherein X is₁₀＝X₆+X_δ2-X₉，X₁₀＝Y₆+Y_δ2-Y₉，X₁₀＝Z₆+Z_δ2-Z₉。

Step S37: and judging whether the final error value of each preset detection point of the processed workpiece is smaller than or equal to the preset error value or not, and whether the included angle between the vector direction of the final error value of each preset detection point of the processed workpiece and the loss at the corresponding preset detection point is smaller than a preset angle or not.

The preset error value may be 0.002mm, and the preset angle may be 90 °.

Specifically, when the final error value of each preset detection point of the workpiece is less than or equal to the preset error value, and the included angle between the vector direction of the final error value of each detection point of the workpiece and the loss at the corresponding detection point is less than the preset angle, it is determined that the processed workpiece 43 is qualified, and step S40 is executed; if not, the processed workpiece 43 is determined to be defective, and step S38 is executed.

The final error value of each preset detection point of the workpiece is smaller than or equal to the preset error value, specifically, the error values in three directions corresponding to the final error value are smaller than or equal to the preset error values; for example, the final error value corresponding to the predetermined detection point C1 of the workpiece is (X)₁₀、Y₁₀、Z₁₀) Then X₁₀、Y₁₀And Z₁₀Are required to be less than or equal to the predetermined error value.

It should be noted that whether an included angle between a vector direction of a final error value at each detection point of the processed workpiece 43 and a normal error at the corresponding detection point is smaller than a preset angle specifically means whether included angles between vectors in three directions (X, Y, Z directions) of the final error values at each detection point of the processed workpiece 43 and the normal error are smaller than the preset angle; for example, the default detection point C1 of the workpiece corresponds to the loss (A)₁、B₁、C₁) If the final error value corresponding to the predetermined detection point C1 of the workpiece is (X)₁₀、Y₁₀、Z₁₀) Then X₁₀、Y₁₀And Z₁₀Corresponding vector and normal (A)₁、B₁、C₁) The included angles between the two should be smaller than the preset angle.

The following describes, with reference to a specific embodiment, a manner of obtaining an included angle between a vector direction of a final error value at one of the preset detection points of the processed workpiece 43 and a normal error at the corresponding preset detection point; specifically, the obtaining manner of the included angle between the vector direction of the final error value of the other preset detection points of the processed workpiece 43 and the normal error corresponding to the preset detection points is similar, and is not repeated here.

For example, the final error value corresponding to the preset detection point C1 of the processed workpiece 43 is (X)₁₀、Y₁₀、Z₁₀) Corresponding loss is (A)₁、B₁、C₁) (ii) a The vector corresponding to the X direction is associated with the normal (A)₁、B₁、C₁) The specific acquisition mode of the included angle is as follows: if X₁₀If the vector is positive, the vector corresponding to the X direction is associated with the normal (A)₁、B₁、C₁) The included angle between the vector (1, 0, 0) and the vector (A1, B1, C1); the calculation method of the included angle between the two vectors is a mathematical formula and a common method, and is not described herein again; if X₁₀If the vector is negative, the vector corresponding to the X direction is associated with the normal (A)₁、B₁、C₁) The included angle between the vector (-1, 0, 0) and the vector (A1, B1, C1); x₁₀0, the vector corresponding to the X direction is associated with the normal (A)₁、B₁、C₁) The included angle between the two is 0; similarly, the calculation method of the included angle between the Y direction and the Z direction is similar to the calculation method of the X direction, and is not described herein again.

Step S38: and judging whether the processed workpiece is over-cut or not.

Specifically, it is determined whether the final error value of the processed workpiece 43 has an absolute value of an error value in at least one direction larger than a preset error value in X, Y, Z three directions, and an included angle corresponding to the direction is smaller than a preset angle; if so, it is determined that the machined workpiece 43 is not over-cut, step S39 is executed, and if not, it is determined that the machined workpiece 43 is over-cut, and step S40 is executed.

Step S39: and the controller switches the detection probe to a machining main shaft of the machine tool and drives the machine tool to reprocess the machined workpiece by using the cutter according to the input compensation machining program.

Specifically, after the compensation machining is completed, the process returns to step S34 to perform the workpiece re-inspection and the machining result determination until the determination result is a machining pass or an over-cut (fail).

Step S40: and finishing processing and detection.

Specifically, other specific implementation processes of the steps S38 to S40 are the same as or similar to the specific implementation processes of the steps S27 to S29 in the numerical control machining and detecting control method provided in the foregoing embodiment, and the same or similar technical effects can be achieved.
