[0002] Hard alloy is widely used in cutting tools, molds and other fields due to its extremely high hardness and wear resistance, but its high hardness (HRC can exceed 70 degrees) and brittleness make its processing extremely difficult, and currently mainly relies on electric erosion processing methods such as electric spark and wire cutting, as well as grinding machine processing methods, which have low processing efficiency and high cost.

DETAILED DESCRIPTION

[0030] The concept, specific structure and generated technical effects of the present application will be described clearly and completely in combination with the embodiments and the drawings below, so as to fully understand the purpose, scheme and effect of the present application.

The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any combination of one or more related listed items.

[0033] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of the present disclosure, the first element can also be referred to as the second element, and similarly, the second element can also be referred to as the first element. It can be understood that the test tool 100 of the present application is made of hard alloy material, and further, the machining hardness of the test tool 100 of the present application is more than HRC 60 degrees or more than HRC 70 degrees.

[0034] Referring to Figures 1 to 5 The test tool 100 for testing the hard alloy machining machine tool of the technical scheme of the present application comprises a combined surface light texture inspection area 110, a vehicle lamp curved surface machining performance inspection area 120, a diamond surface machining performance inspection area 130, a grooving capacity test area 140 and a stamping die diversity inspection area 150. Further, the combined surface light texture inspection area 110 comprises a machining surface combined by any two or more of a plurality of machining surfaces such as bevel, round surface and flat curved surface.

[0035] Referring to Figures 1 to 5, the combined surface light grating fineness test area 110, the car lamp curved surface machining performance test area 120 and the diamond surface machining performance test area 130 are parallel strip areas extending from one side of the test tool 100 to the other side. The slotting capacity test area 140 is arranged between the strip area and the stamping tool die diversity test area 150, and forms a recess. Such a layout makes the machine tool machining spindle efficiently test back and forth in the combined surface light grating fineness test area 110, the car lamp curved surface machining performance test area 120 and the diamond surface machining performance test area 130, saving test time. Moreover, considering that the combined surface light grating fineness test area 110, the car lamp curved surface machining performance test area 120 and the diamond surface machining performance test area 130 are three areas with great differences in test machining mode with the stamping tool die diversity test area 150, therefore, the slotting capacity test area 140 is used for partitioning, so that the three areas and the stamping tool die diversity test area 150 do not interfere with each other, reducing the influence of machining debris on each other, thereby improving the machine tool detection effect. Preferably, referring to Figure 4 and Figure 5 , the strip area composed of the combined surface light grating fineness test area 110, the car lamp curved surface machining performance test area 120 and the diamond surface machining performance test area 130 can form a house type transition surface, so as to better detect the multi-axis machining linkage performance of the hard alloy machining machine tool in the machining process of the curved surface.

[0036] Referring to Figures 1 to 5 , the test method for testing the hard alloy machining machine tool of the technical scheme of the present application comprises:

[0037] S100, inputting a plurality of test areas of the test tool 100 and machining processes corresponding to the test areas to the machine tool to be tested;

[0038] S200, after determining the current test area and the current machining process by the machine tool to be tested, starting the machine tool to machine the current test area;

[0039] S300, according to the machining effect of the current test area, combining the preset machining effect and the machine tool performance test standard, judging whether the corresponding performance of the machine tool to be tested is qualified, and determining the performance of the machine tool to be improved;

[0040] S400, repeating steps S200 to S300 until the machine tool to be tested completes the machining of all test areas of the test tool 100.

[0041] The present application can be used to check whether the machine tool meets the requirements of cemented carbide machining, which combines surface machining, light curve machining, diamond surface machining, slotting machining and stamping tool die machining of the machine tool on the test tool 100 of cemented carbide material, and judges whether the machine tool meets the requirements of cemented carbide machining according to the machining result, and determines the performance deficiency of the machine tool according to different adverse effects, so as to improve the machine tool deficiency.

[0042] Compared with ordinary metal material machining, cemented carbide machining has very high process threshold, and the current machine tool, tool and machining process are not mature in the cemented carbide machining industry. The existing cemented carbide machining mainly has discharge, wire cutting and grinding machine and other ways. According to the processing difficulty of cemented carbide and the characteristics of the machine tool required for processing, the present application designs a test tool 100 containing multiple test areas to judge whether the machine tool meets the requirements of cemented carbide machining according to the real machining effect, and to determine which aspects of the machine tool performance need to be improved, so as to realize that CNC equipment can be used for cemented carbide machining.

[0043] Specifically, in the traditional machine tool debugging and machining, the technician first processes the raw material according to the product shape. Because the product machining shape has uncertainty, the technician can only judge which aspect of the machine tool performance is the problem according to the machining effect and combined with his own experience, and then adjust the performance and verify the machining again. If the technician's above judgment is incorrect, it is necessary to find the reason again and verify the machining again. The verification process is repeated and tedious, and it depends on the technician's technical level, and it is difficult to control the length of the debugging cycle. In the test method of the present application, the machining area of the test tool 100 is designed in advance, and the corresponding area is machined by the machine tool. Because the adverse effects of machining and the corresponding machine tool performance are known in advance, for example, the oversteering of the negative angle of the diamond surface machining is because the machine tool does not control the micro deceleration at the corner, so that the technician can determine which aspect of the machine tool performance needs to be adjusted after completing the machining of the test tool 100, which saves the process of artificial judgment and machining verification, provides effective basis for evaluating the machining capacity of CNC machine tool, and provides reliable basis for process optimization and quality control.

[0044] Further, the present application is designed according to the defects existing in the prior art, combined with the processing difficulties of hard alloy, and combined with the required machine tool processing characteristics, a testing tool 100 including a combined surface light line fineness test area 110, a vehicle light curved surface processing performance test area 120, a diamond surface processing performance test area, a slotting ability test area 140 and a stamping tool die diversity test area 150, so as to test the performance of the machine tool, and according to the preset machine tool performance test standard corresponding to the processing effect of the test tool 100, quickly judge whether the machine tool meets the hard alloy processing requirement, and which aspect performance needs to be improved. According to the processing effect of the different test areas of the test tool 100, the performance of the machine tool can be comprehensively evaluated.

[0045] In some embodiments, the combined surface light line fineness test area 110 is used for light line fineness test of any combination of inclined surface, curved surface, flat curved surface and other processing surfaces. Specifically, the present application first performs three-axis parallel finishing of any combination of surfaces on the combined surface light line fineness test area 110 of the test tool 100 by the machine tool to be tested, to test whether the tool marks of the three-axis linkage processing hard alloy are consistent and whether the bright and dark lines phenomenon occurs. When the machining material hardware reaches HRC65 or above, the tool is prone to vibration, tool change and other conditions during cutting, resulting in tool marks disorder, tool marks roughness and other phenomena on the combined surface. The present application judges the processing performance of the machine tool according to the processing effect of the test tool 100, but when the above tool marks disorder, tool marks roughness and other adverse effects occur, it can be reasonably judged that the machine tool is not suitable for processing hard alloy materials.

[0046] In an application embodiment, the method of the present application analyzes the processing performance of the machine tool to be tested according to the processing effect of the test tool 100, and judges whether the machine tool meets the hard alloy combined surface processing requirements. For example, according to the effect of the tool marks, such as tool mark disorder, tool mark roughness, etc., it can be judged that when the machine tool processes materials with high hardness, due to the insufficient rigidity of the Z-axis and the main shaft, micro-vibration occurs during cutting, resulting in different bright and dark lines on each processing surface. Further, due to the insufficient vibration suppression of the machine tool to be tested, the vibration during processing is too large, resulting in easy wear of the tool, and further tool mark disorder phenomenon, so that the performance of the main shaft and Z-axis of the machine tool to be tested can be targetedly strengthened according to the above test results.

[0047] In some embodiments, when the vehicle lamp curved surface machining performance test area 120 is machined, the present application performs three-axis linkage finishing machining on the vehicle lamp curved surface machining performance test area 120 by the machine tool to be tested, so as to test whether the sharp corner position of the machined surface appears corner collapse, becomes a round corner, and the like, and test whether the machined surface can normally appear a reflection effect, that is, test the uniformity of the surface reflection of the machined surface. When an adverse situation occurs, it can be judged that the machine tool is not suitable for machining hard alloy materials. Specifically, because the arc surface inside the vehicle lamp is very small and cannot be processed in the later period, the consistency of each lamp surface is required to be very high. When an adverse situation occurs in one of the lamp surfaces, the entire vehicle lamp surface needs to be reprocessed, so the overall stability of the machine tool is required to be very high for machining the vehicle lamp curved surface. Preferably, a light source and a detection camera for testing the surface reflection brightness of the machined surface can be arranged above the testing tool 100.

[0048] In an application embodiment, the present application judges whether the three-axis dynamic performance, spindle vibration performance, and thermal stability performance of the machine tool to be tested meet the requirements of hard alloy vehicle lamp curved surface machining according to the actual machining effect of the machine tool to be tested on the testing tool 100. For example, when the reflection of the vehicle lamp curved surface is not uniform, it can be judged that the overall thermal performance of the machine tool does not meet the requirements of machining hard alloy. Specifically, the key components such as the spindle and guide rail of the machine tool are deformed due to heating, which causes the tool path to deviate, thereby causing the reflection characteristics of the machined vehicle lamp curved surface to be poor. Therefore, the cooling system or the thermal compensation process of the control system of the machine tool to be tested needs to be optimized. For example, because hard alloy has the characteristics of being hard and brittle, when the spindle vibration is too large, the corner collapse phenomenon is prone to occur in the vehicle lamp curved surface machining performance test area 120. When the dynamic response performance of the servo of the machine tool, the rigidity of the machine tool, and the dynamic response performance of the tool compensation are insufficient, the round corner phenomenon is prone to occur in the vehicle lamp curved surface machining performance test area 120. The present application can improve the overall thermal performance, spindle vibration, and dynamic response performance of the machine tool to be tested according to the machining effect of the vehicle lamp curved surface machining performance test area 120.

[0049] In some embodiments, when the diamond surface machining performance test area is machined, the present application performs three-axis linkage finishing machining on the diamond surface machining performance test area by the machine tool to be tested. Because it is necessary to continuously switch between the sun angle (acute angle ≤ 30°) and the shade angle (R0.1-R0.5 mm), the continuous change of the slope causes the complexity of the machining path to increase dramatically. When continuously reversing, the shade angle is prone to overshoot, and the sun angle is prone to become a round corner due to the dynamic response lag of the machine tool. When the tool tip is used to machine the shade angle, it is also difficult to keep the upper and lower surfaces of the shade angle consistent. Therefore, according to the machining effect of the diamond machining performance test area of the testing tool 100, it can be judged whether the acceleration and deceleration control of the machine tool is reasonable. In particular, according to the machining effect when the Z-axis is high-strength reversed, it can be judged whether the selection of the servo motor and driver of the machine tool is qualified.

[0050] In an application embodiment, the present application judges whether the performance of the machine tool can meet the requirements of hard alloy diamond face machining according to the machining effect of the diamond face machining performance test area of the test tool 100. For example, when machining the male and female corners of the diamond face, continuous acceleration and deceleration is required. According to the machining effect of the test tool 100, it can be determined whether the speed adjustment scheme is reasonable and whether the matching consistency of each movement axis meets the requirements. Moreover, for diamond face machining, in addition to the male and female corners, the surface finish of the flat bevel is also important. When the Z-axis moves up and down continuously, the tool wear will be accelerated, thereby affecting the bevel finish. Specifically, to make the machine tool run more smoothly, when the machine tool needs to control the speed, it needs to decelerate slightly in advance at the corner to avoid overcutting of the female corner or rounding of the male corner, or leaving vibration marks due to vibration, and to reduce the three-axis combined speed to reduce the garbage points (redundant points) of the program, thereby avoiding the appearance of ripples or uneven roughness on the flat bevel. Therefore, according to these machining effects of the diamond face machining performance test area, the dynamic performance of the machine tool to be tested, tool life management, and system speed control algorithm need to be improved to adapt to the requirements of hard alloy machining.

[0051] In some embodiments, when machining the slotting capacity test area 140, the present application tests whether the tool can effectively cut and whether the tool produces resonance, and whether the machine tool produces high-frequency harsh sound during cutting, by rough slotting of the slotting capacity test area 140 by the machine tool to be tested under the machining state of full stress of the tool in the axial and radial directions. For the slotting function, the overall performance matching of the machine tool is required to be very high, and the axial stiffness and radial stiffness need to be highly matched, and both are indispensable.

[0052] In an application embodiment, the present application judges whether the machine tool meets the machining requirements of the hard alloy slotting process according to the machining effect of the slotting capacity test area 140 of the test tool 100. For example, when slotting hard alloy, the three-axis rigidity of the machine tool is required to avoid adverse phenomena such as tool withdrawal or structural deformation. When the cutting force is not enough, the test tool 100 will have defects such as corner collapse and edge collapse, and when high-frequency harsh noise occurs during machining, the machining parameters need to be adjusted in time to avoid excessive vibration and produce defective products. Therefore, according to the machining effect of the slotting capacity test area 140 of the machine tool to be tested, the axial and radial stiffness matching of the machine tool and the machining parameter setting can be improved to adapt to the requirements of hard alloy machining.

[0053] In some embodiments, when the stamping die diversity test area 150 is processed, the present application tests the stamping die diversity of the stamping die diversity test area 150 by the testing machine tool. Although the carbide die has a high service life in stamping, it is also difficult to process, and the cutting edge is prone to notches, uneven cutting edge, etc. Especially when the cutting force is too large, it is easy to cause notches on the cutting edge. Therefore, the flatness and surface finish of the die have a decisive effect on the cutting quality of the product, so the vibration suppression performance and the inter-axis linkage performance of the machine tool are required to be higher, and the current fluctuation amount needs to be strictly controlled in system and drive debugging.

[0054] In an application embodiment, according to the processing effect of the stamping die diversity test area 150 of the test tool 100, it is judged whether the machine tool meets the processing requirements of the stamping die diversity. Specifically, the stamping die diversity test area 150 is provided with a plurality of arc-shaped processing paths with different curvatures. For example, when the test tool 100 has a cutting edge notch or uneven cutting edge, the vibration source of the machine tool can be handled first, and the spindle dynamic balance, rigid clamp, etc. are adjusted to suppress the vibration of the machine tool. Secondly, the linkage synchronization performance of each motion shaft needs to be finely adjusted, and the current fluctuation amount needs to be supplemented in real time, and the cutting parameters need to be optimized to reduce the cutting force and increase the linear speed, so that the suppression performance, motion control performance and processing parameter setting of the machine tool can meet the processing requirements of the carbide.

[0055] In some embodiments, in order to speed up the test speed of the carbide, after the processing test, the rigidity tester is used to analyze the rigidity of the machine tool, and the vibration tester is used to analyze the overall frequency of the machine tool. When the tool is allowed to cut during processing, the spindle characteristics are analyzed. When the edge collapses, the angle is missing, and the vibration marks appear during processing, the oscilloscope is used to split the curves of the three axes.

[0056] It should be noted that, unlike the existing debugging method, the present application can determine which aspect of the machine tool performance is insufficient according to the processing effect, and perform targeted debugging, that is, the present application can obtain the mechanical data from the processing effect, obtain the mechanical deficiencies from the defects, and understand how the vibration marks are generated during debugging. It can be understood that when the hardness is high, the traditional single debugging method is difficult to subdivide the processing problems, because when processing high-hardness materials, there will be more problems that cannot be seen, for example, when the tool contacts the workpiece, is the tool allowed to cut, or is the tool already bent, which is difficult to reflect from the electrical debugging. After the test tool 100 is tested by the test method of the present application, the specific defects of the machine tool can be obtained from the processing defects, and the specific defects obtained are used as the starting point for targeted improvement of the machine.

[0057] By simulating the actual machining working condition of three-axis simultaneous force, the rigidity, vibration suppression performance and micro-vibration characteristics of the machine tool can be comprehensively evaluated, the three-axis linkage synchronization and system resonance tendency can be effectively detected, and the current waveform curve visualization technology can provide data support for the optimization of machine tool dynamic performance. The unique design not only verifies the feasibility of cemented carbide in CNC milling machining, breaks through the technical limitations of traditional electro-erosion and grinding machining, significantly reduces the machining process and improves the production efficiency by more than 30%, and more importantly, establishes a process specification system for cemented carbide milling machining. The test piece provides a key research and development verification tool for machine tool manufacturers, and through quantitative analysis of the stress state and vibration spectrum characteristics of the stamping die blade, guides the optimization of machine tool structure and debugging of control system, so as to improve the core technical competitiveness of machine tool manufacturers in the field of high-end cemented carbide machining equipment.

[0058] The test tool 100 and test method for testing the cemented carbide machining machine tool of the present application provide a general test tool 100 that can test whether the machine tool can process cemented carbide during processing, so that the machine tool development technician can determine whether the machine tool part stability meets the processing requirements during the design process, and can effectively evaluate the rigidity and vibration suppression of the machine tool, and provide effective basis for improving micro-vibration. Using the test method of the present application to perform the set processing procedure, the processing effect of the test tool 100 of the present application under the three-axis simultaneous force working condition can be used to quickly determine whether the machine tool is prone to resonance when processing cemented carbide. In system debugging, the three-axis linkage synchronization, the visualization of the current waveform curve, and the influence on the stamping die blade provide real effect basis for the machine tool to determine whether the machine tool meets the cemented carbide processing performance. By testing the cemented carbide processing effect of the CNC machine tool through the present application, the current situation that cemented carbide can only be processed by electro-erosion and grinding can be changed, and the processing inspection steps can be reduced and the processing efficiency can be improved. In addition, according to the principle and test method of the test tool 100, the processing method and processing requirements in the processing of cemented carbide are summarized, so that the CNC machine tool can truly mill cemented carbide.
