Numerical control program converter of three-coordinate measuring machine

Abstract

The invention relates to a numerical control program converter of a three-coordinate measuring machine. The numerical control program converter includes a measuring machine configuration module (1), a measuring head and measuring seat definition information extraction and angle conversion module (2), a detection coordinate system definition and transform information extraction module (3), a to-be-measured characteristic definition information extraction module (4), a measurement point extraction and path generation module (5), a dimension and tolerance definition information extraction and processing module (6), a detection point compensation and storage mode selection module (8) and a detection program output module (9). Compared with the prior art, and according to the control code converter of the invention, DMIS control codes generated by off-line programming software are converted to control codes meeting the requirements of measuring equipment through a measuring machine structure, measuring seat types, a detection coordinate system in CAD software, size tolerance and measuring paths. The numerical control program converter is suitable for any three-coordinate measurement equipment. With the numerical control program converter adopted, the increase of related equipment can be avoided, and financial and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of computer aided manufacturing and detection, in particular to a numerical control program converter for a three-coordinate measuring machine. Background technique [0002] There are mainly two programming methods for three-coordinate detection: self-learning online programming and offline programming. Self-learning on-line programming is the main programming method at present, but it is not conducive to the large-scale application of three-coordinate detection technology in model production. Self-learning on-line programming is a method that needs to be programmed on the control terminal (computer) connected to the measuring machine. The method is to control the movement of the measuring machine while programming, which takes a long time and has limited functions. The off-line programming method is based on the CAD model, does not require a measuring machine or an actual workpiece, and can be completed be...
