Abstract

PURPOSE:To repetitively display a desired area by reversing temporarily the simulation during its execution. CONSTITUTION:The presence or absence is checked for a command given from an operation switch (S1). If no command is received from the operation switch, a working program is read out of a memory in the same way as conventional for interpolation arithmetic and at the same time the position of a tool is displayed on a CRT display device 24. Then the contents of the operation which are analyzed with push of this switch and the simulation of the tool is traced back along its hitherto locus (S4). When such a command is supplied for simulation of the tool so that the moving direction of the tool is reversed in terms of time, the coordinate position set when said command is received is defined as a start point and the start point of a block under interpolation arithmetic is replaced with an end point. For instance, a command is received at a position Pi as shown in the diagram. Then the position Pi is defined as a start point and a start point P2 of a block B is replaced with an end point.
