Optimization of Hard Milling Processing for Convex Surface Joining Die with Milling Force Control

  • 摘要: 机械加工对于模具结构的要求日益复杂,导致在模具自由型面上存在大量沟槽、凸凹等结构,容易出现磨损严重、拉毛拉裂等问题。对于模具不同位置所需要的应力特征不同,多采用镶块式模件拼接后整体铣削加工。而拼接处存在铣削力的突变导致刀具磨损过快和型面精度不高问题。本文通过阐述球头刀铣削凸曲面拼接模具表面形成机理,分析了铣削过程中不同位置的刀具-工件的接触关系;并且以球头铣刀加工不同硬度的淬硬钢Cr12MoV凸曲面拼接模具试验为对象,揭示切削深度、切削速度、每齿进给量及刀具铣削方向对拼接处铣削力突变的影响规律;以铣削力突变最小为目标进行正交试验研究,得到考察指标的主次影响规律和最优参数组合。
