Minimum vicinity interpolation algorithms for calculation of trajectory processing for a model of CNC machine tool

Abstract

This article aims to present two interpolation algorithms (linear and circular) based on minimum vicinity method, developed and tested by the authors, required in the trajectory processing for CNC machine tools. The algorithms for linear and circular interpolation using the minimum vicinity method is part of the algorithms that calculate a function. The points that are chosen are the closest to the calculated circular or linear trajectory. Testing and validation of algorithms has been achieved by implementing a model of machine tool using a computing system that consists of a PC/104 computer type, a data acquisition system and control ADA1100 and for the model of machine tool was used an X-Y recorder.
