Method and apparatus for calculating working data

加工データ算出方法及び装置

Abstract

【課題】加工工具の形状変化量を考慮して、より高い加工精度が得られるようにする。 【解決手段】加工工具により被加工物を研削又は研磨加工する場合の加工工具の移動軌跡である加工データを算出する方法であって、加工工具の加工距離又は加工開始からの経過時間に基づいて、加工工具の形状変化量を予測する第1の予測工程7と、第1の予測工程において予測された加工工具の形状変化量に基づいて、加工工具の形状変化がないとした場合の加工データに補正を加えるデータ補正工程9とを具備する。 【選択図】 図1
<P>PROBLEM TO BE SOLVED: To obtain a higher working precision by taking a variation in shape of a working tool into consideration. <P>SOLUTION: A method for calculating working data which is a moving locus of the working tool when grinding or polishing an article to be worked by the working tool includes a first prediction step 7 for predicting the variation in shape of the working tool based on a working distance of the tool or elapsed time from the start of working, and a data correction step 9 for correcting the working data when no variation in shape of the tool is recognized based on the variation in shape of the tool predicted in the first prediction step. <P>COPYRIGHT: (C)2005,JPO&NCIPI
