NUMERICAL CONTROLLER HAVING DISPLAY FUNCTION FOR TRAJECTORY OF TOOL
First Claim
1. A numerical controller comprising:
- a numeric controlling part which controls at least one drive axis of a machine tool;
a tool coordinate calculating part which calculates a first feedback trajectory of a representative point of a tool based on position feedback of the drive axis and information of a mechanical structure of the machine tool;
a tool trajectory storing part which stores the first feedback trajectory; and
a displaying part which displays the first feedback trajectory,wherein the displaying part displays at least one past second feedback trajectory which is stored in the tool trajectory storing part on the first feedback trajectory displayed on the displaying part so that the second feedback trajectory is overlapped with the first feedback trajectory.

Abstract
A numerical controller capable of visually and accurately analyzing a change of the tool trajectory before and after changing a processing condition, whereby a parameter of a drive axis can be properly adjusted. The numerical controller comprises a numeric controlling part which controls each drive axis based on a predetermined position command; a position data obtaining part which obtains position data of each drive axis controlled by the numerical controlling part; a tool coordinate calculating part which calculates a coordinate of a tool center point based on position feedback or obtained position data of each drive axis and information of a mechanical structure of a machine tool; a tool trajectory storing part which stores the calculated coordinate of the tool center point as a feedback trajectory; and a displaying part which displays the stored feedback trajectory on a display.
