Abstract

The invention relates to a STEP-NC decoder development method of an open numerical control system based on Linux. Through analysis of an STEP-NC data model structure, a decoding method of STEP-NC codes of an open type numerical control system based on Linux is researched, a decoding working process of an STEP-NC decoder is designed, and functional modules such as a reading module, a data mapping module, a storage module and a planning module of the STEP-NC decoder are developed. The STEP-NC decoder is integrated in the open type numerical control system based on Linux, so that the configurable NC decoding mode is realized. The STEP-NC decoder developed by the method can identify 2.5 D manufacturing features defined in the ISO 14649 standard, extract geometric information and processing information, and generate a tool path which can be used for actual processing.

Description

technical field [0001] The invention relates to the technical field of numerical control automation, in particular to a method for developing a STEP-NC decoder of an open numerical control system based on Linux. Background technique [0002] NC decoding is an important part of realizing the automation of the NC system. It can realize the decoding of the NC program code, obtain relevant NC processing information, and realize the automatic processing of the NC system. At present, the two most commonly used NC decoding schemes at home and abroad are based on ISO 6983 standard code (G / M code) and ISO 14649 standard code (STEP-NC code). Since the G / M code does not contain information about workpiece characteristics such as part material, part geometry, and tool trajectory planning, its shortcomings have gradually been revealed in the development of high-precision CNC, which limits the improvement of production efficiency. The data model of the STEP-NC code is oriented to the wor...
