ABSTRACT:
When a position of a tool blade tip for displaying the work shape, tool shape and tool locus is calculated by an interpolation arithmetic operation based on the interpolation instruction and feed speed instruction within a numerical control data, the calculated position of the tool blade tip is compared with the display scope every time an interpolation arithmetic operation is conducted; a determination is made as to whether or not the tool shape and tool locus to be displayed are inside of the display scope, and when they exist outside, uses a higher speed as the feed speed for the interpolation arithmetic operation. Therefore, even when an operator tries to check numerical control data by reducing the display scope for local graphic display, the interpolation outside the display scope can be conducted at a higher speed to thereby allow the operator to check the numerical control data quickly and immediately.
