切削力对长轴类零件产生最大径向误差的计算

The Calculation of Largest Radial Error for Cutting Force on the Long Axis Parts

分析车削长轴类零件时,车削工艺系统的刚度随切削分力Fy作用点位置不同而引起的工件径向误差变化规律,整理出其函数关系式,并采用最优化技术,快速获得工件径向误差的精确值。

The rigidity of turning system changes with the different acting position of radial cutting force when turning long axis parts, and it results in workpiece radial error. The variation of workpiece radial error with radial cutting force was discussed, the function formula was deduced, by using optimization technology, the precise value of the radial error was got rapidly.
