NC工作機械の工具移動軌跡に生ずる誤差とその入力適応系

抄録

This paper reveals the cause of the machining error of free form the surface when providing the NC command by continuous short blocks. This paper proposes a method to decide a limit value of the distribution to realize the machining error within allowable tolerance, and also a method of acceleration and deceleration of the motion that machines faster as possible as under those limitations. The proposed methods can be installed not only into NC. equipment but also into personal computer that process CAM data out of NC., and are able to increase twice the productivity of existing machine tool by small additional costs.
