Abstract

A working control device for controlling a machine tool having spindles and moving a tool relative to a workpiece. The working control device (3) has tool trajectory generation means (34) for generating a first tool-trajectory, partial trajectory calculation means (35) for splitting the first tool-trajectory into partial trajectories such that the greater the curvature of each trajectory, the smaller the length of the trajectory, spindle control data calculation means (36) for obtaining a change in the speed of each spindle for each partial trajectory, and simulation means (38) for drawing a second tool-trajectory based on the change in speed of each spindle. The first tool-trajectory is generated based, for example, on a product shape to be formed on a workpiece.
