Abstract

The invention provides a method and a device for performing multi-section characteristic generating four-axis codes used for processing parts. The method comprises the following steps: 1, picking up the profile curves of multiple sections, setting the technological parameters of the multi-section characteristic processing; 2, dispersing the profile curve of each section into evenly distributed discrete points with equal number according to the technological parameters; 3, connecting the corresponding discrete points of adjacent sections into a processing trace for the multi-section characteristic processing according to line segments; and 4, generating the four-axis codes according to the processing trace of the multi-section characteristic processing. The invention effectively solves the processing of parts with multi-section characteristic and the problem of four-axis programming, reduces the difficulty and risk of operation, enhances the security of processing, improves the qualification rate of product processing, shortens the preparation time of processing, improves the production efficiency, saves money and lowers cost.

Description

technical field [0001] The invention relates to a method and a device for generating codes, in particular to a method and a device for processing multi-section features and generating four-axis codes. Background technique [0002] As the performance of CNC machine tools develops towards high-speed, high-precision, and compound aspects, fully developing and utilizing the functions of machine tools has become the work content of CNC programmers and CNC processing personnel. For CNC lathes, generally only X-axis and Z-axis linkage interpolation can be performed, thus limiting the processing range of parts. The two-axis CNC lathe can only realize the linkage between the X-axis and the Z-axis, and process parts such as discs and shafts. It cannot process parts with multi-line section profiles, nor can it process parts with multi-section profiles. In order to meet the production requirements of complex parts, it is necessary to make full use of the four-axis capabilities. The C ...

For CNC lathes, generally only X-axis and Z-axis linkage interpolation can be performed, thus limiting the processing range of parts

The two-axis CNC lathe can only realize the linkage between the X-axis and the Z-axis, and can process parts such as discs and shafts. It cannot process parts with multi-line section profiles, nor can it process parts with multi-section profiles.

The two-axis lathe can only process simple rotary bodies, which is far from meeting the needs of production

Four-axis lathes have been widely used in workshops, but because the matching processing code generation software has not yet been released, many four-axis lathes are idle or only used as simple CNC lathes, which have not been fully utilized, seriously affecting production efficiency

[0006] 1) Manually writing processing codes takes a long time, is prone to errors, and cannot be competent for programming parts with complex shapes

According to foreign statistics, when manual programming is used, the ratio of the writing time of a program to the actual time of processing on the machine tool is about 30:1 on average, and 20% to 30% of the reasons why the CNC machine tool cannot be started are Due to the difficulty in programming the machining program, the programming time is longer

[0007] 2) It is difficult to write four-axis programs, there is no special four-axis code generation software, many four-axis CNC lathes are idle or only used as ordinary CNC lathes, and have not been fully utilized
