Machine Coordinate Values Exchange Model Design and Analysis

Abstract

Continuing improvements in computer and machine tool technology have led to many new and fascinating applications in CAD/CAM systems. One of the most fruitful areas of CNC machine research is kinematic analysis, which describes the mapping between the set of cutter position and orientation and the set of joint variables. There has thus far been relatively little research into the mapping between the set of joint variables of machine tool and set of joint variables of another machine tool. In this thesis we develop a method called machine coordinate values exchange (MCVE) model, which aims to deal with this kind of analysis. This proposed methodology is a mathematical form, applicable to both academic research and production, and enables the direct and rapid generation of joint variables. This study also presents a novel graph, called an isometric schematic, to conceptualize the prototype of multi-axis machine, and establishes and shows the feasibility of the MCVE model for two different types of machine tools.
