Numerical controller facilitating measure to be taken after detection of interference

摘要

A numerical controller controls driving of an axis installed in a machine based on an instruction of a program, and when predictive detection of occurrence of interference between a movable part which moves by the driving of the axis and another object is made, the numerical controller decelerates and stops movement of the movable part. Further, the numerical controller changes a display attribute of information display relating to the axis based on an operation state of the axis which is being driven when predictive detection of occurrence of interference is made, and displays a coordinate value according to the display attribute that is changed by the attribute change processing part.
