A study of the Volumetric Error Compensation and Virtual Machining System in a Machine Tool

공작기계의 체적오차 보정과 가상가공 시스템에 관한 연구

The objective of this study is to estimate and to compensate for the volumetric error of a machine tool. In this paper, the volumetric error is defined and error synthesis model is presented. Then, the volumetric error of workpiece is compared through the virtual machining and a new tool-path is generated to compensate for the error in the post-processor of CAM system using the error synthesis model. By this method, the error is compensated without modification or replacement of a machine tool being in use.
