Research on NC machining technology based on cutting tool creep-feed in feed direction

摘要

【中文文摘】通过对数控加工中存在的问题分析,提出了一种在数控加工中,刀具在被加工工件曲面上沿进给方向蠕动式切削加工的方法,通过刀具与工件时续分离和切削,改善了工艺系统的刚性,从而使工件的加工精度得到改善,并具体从被加工工件的几何形状、切削过程中刀具受力情况及切削区的切削热释放情况方面,分析了采用该方法对加工精度的改善情况。【英文文摘】Based on analyzing problems that general NC machinining process exists, this paper proposes a machining method cutting tool creep-feed machining work piece in feed direction .When cutter is fed toward and away from work piece,it can improve the rigidity of mechanics system,so that machining precision is improved. Other advantages of this process include a superior surface finish,low tool pressure, and cutting heat released easily in the cutting section.
