Abstract

The post-processor is an important interface that transforms cutter location data into numerical control (NC) data. The data compensation in a five-axis machine is quite complex, because of a variety of the machine centers and the computerized numerical control (CNC) system. Since most work on the five-axis post-processor method has dealt primarily with the generation of NC code, this study breaks with tradition and introduces a post-processor with optimization tool radius compensation and a general machine configuration. Furthermore, a practical method for optimizing the NC code is presented that is based on further study of tool compensation and tool wear. The proposed post-processor is validated for various five-axis machine centers using a generalized kinematic model and various cutting tool models. The results of the verification tests showed that proposed post-processor approach can be used to accurately convert the cutter location into NC codes, and the optimized NC code generated by the optimization tool radius compensation method demonstrates the practical value of the proposed approach for improving processing quality and reducing the total machining time and cost.
