Numerical control code converting method

Abstract

The invention discloses a numerical control code converting method which comprises the following steps of: judging the type of a machine tool which has the same machining method with a source system; judging the type of a machine tool which has the same coordinate system with the source system; carrying out convertible judgment of shaft and coupling conditions; carrying out the optimal selection of the machine tool type; obtaining a multiple element of a numerical control code function in a numerical control program, and carrying out the similarity judgment of functions and program formats; finishing the optimal selection of the functions and formats; carrying out the difference judgment of code functions, and solving the difference by using a characteristic quantity value converting method and a function decomposing and combining method to call a kernel problem; and realizing the code conversion by using a code generating algorithm of the STEP (Standard for the exchange of product model data) and an algorithm of generating an ISO6983 standard numerical control code by using STEP neutral files.

Description

Technical field [0001] The invention relates to a conversion method, in particular to a numerical control code conversion method. Background technique [0002] Although the existing numerical control processing equipment of different manufacturers all adopt ISO6983 standard code as the numerical control program format, many programming details are still different. That is to say, the NC machining program code applicable to a certain NC system may not be fully applicable to another NC system, and the respective NC programs must use their own system-specific interpreter to run. In order to solve the problem of NC code sharing between different systems, the basic technologies currently used are: [0003] 1. Reverse the 3D model from the NC code to regenerate a new NC program [0004] Main technique: [0005] According to the existing processing code, using the existing 3D modeling software, reverse engineering can be used to reverse the existing CNC processing code to reconstruct the ...

Problems solved by technology

[0008] (2) This method often causes distortion of the reconstructed 3D model, especially the existing code based on the ISO6983 standard is based on the machining process and machine tool action, and lacks an accurate description of the topological relationship of geometric elements, so it will produce large conversion error

[0009] (3) Poor confidentiality

[0010] (4) High requirements for operators

[0018] (2) There is no effective and unified representation of the information and knowledge contained in the NC code

[0019] (3) Most general-purpose CNC code compilers involve the conversion to low-level computer languages, such as compiling into assembly language, which is bound to consider hardware, which increases the difficulty of designing the system

[0020] (4) Lack of consideration of the latest STEP and STEP-NC standard CNC interpreter, artificially creating another form of special compiler

[0025] (1) It can be seen from the above that as a standard, STFP-NC is far from perfect, and the NC interpreter based on this standard is still in the exploratory stage. Therefore, for a long time in the foreseeable future, the mainstream NC The program code is still based on the ISO6983 standard
