Problems solved by technology

[0002] In aviation, aerospace, shipbuilding and other industries, there are some early versions of Siemens CNC system horizontal five-coordinate CNC machining centers, these early versions do not support advanced processing modes such as TRAORI tool tip tracking, and CNC programming needs to know the table surface to the horizontal flip axis The height difference between the center lines (hereinafter referred to as the height of the flip point) and the height of the fixture during processing can only be generated after calculation by inputting these values ​​into the post file. If the flip height or the height of the fixture is Adjustment, the original NC program cannot be used, and the NC program must be regenerated according to the new height value for replacement, and the NC program cannot be solidified; at the same time, if there are multiple CNC machines of the same type in a workshop, but due to the difference in the turning height of the worktable, the processing For the same type of parts, it is necessary to compile a set of CNC programs for each machine tool, which is time-consuming and laborious, affects production arrangements, and subsequent management is also very troublesome. If the CNC system is replaced with a new version, the cost is very high and the cycle is very long. Few companies are willing Investing a lot of cost to improve these old machine tools requires the development of a programming method based on the old CNC system to eliminate the above-mentioned unfavorable factors

Embodiment Construction

[0017] An embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] In the embodiment of the present invention, such as figure 1 As shown, after the part is rotated at the same angle at position 1 (flip origin) and any position 2, the position of the tool position in the machining track relative to the programming coordinate zero point of the part is the same, and there is only difference with the origin G54 of the machining coordinate system, as long as the The difference between them can realize that the NC program has nothing to do with the fixture and the turning height; in the figure, 2 indicates the turning point, 3 indicates the programming coordinate zero point, 4 indicates the machining coordinate system G54, and 5 indicates the machining position of the tool;

[0019] In the embodiment of the present invention, the CNC machine tool processing method for eliminating the difference in height and position...

Abstract

A numerical control machine tool processing method capable of eliminating height position difference belongs to the technical field of numerical control processing. According to the method, by determining a sampling point of which the A-axis angle changes in the process path of a cutter, extracting the A-axis angle value corresponding to the point, obtaining a new processing coordinate system zero position according to the extracted A-axis angle value and an original processing coordinate system zero position and translating the original processing coordinate system zero to the new processing coordinate system zero position, the process path of the machine tool cutter is always related to the coordinate zero of parts only. By adopting the method, the problem that the machine tool utilization rate is low and the height of a workbench and the height of a clamp must be taken into consideration during programming and processing as the old-version Siemens numerical control system machine tool has no cutter point tracking function is solved, and the amount of programming and the management risk are reduced. The method has been popularized and applied in exterior profile processing of complex crankcase parts. The numerical control efficiency of the numerical control machine tool is improved greatly, the waiting time for the machine tool is reduced, and arrangement of workshop production tasks is facilitated.
