摘要
数控加工刀具运动轨迹是确定数控加工工艺的重要环节。刀具运动轨迹设计质量的好坏,将直接影响零件的加工质量及加工成本。以切削力波动最小为目标,加工屏凸模表面刀具切削路径优先选择三维偏置法,其次选择最佳等高法。球头刀铣削切削力实验表明切削力波动与曲面曲率变化有关,随着被加工表面曲率的增大,切削力在减小,加工时应选取曲面曲率最大的方向作为刀具运动轨迹方向。
Tool path of NC machining is one of the important parts to determine NC machining process. Whether the tool path quality is good or bad will directly affect the machining quality and the machining cost of part. Aiming at little fluctuation of cutting force of glass bulb panel' s surface, the best tool path is three dimension and the second is furthest highness. From the experiment of ball - end milling cutting tool, we can see that with the increase of the surface' s curvature, cutting force decreases, so we should choose the biggest curvature as our tool path.
