Abstract
A numerical controller for performing table-format-data-based operation control includes a reading unit that analyzes a command block read from table format data to acquire a reference value and a coordinate value of a control point and outputs the reference value and the coordinate value, a segment distinction unit that divides movement to the control point into acceleration/deceleration segments and a constant speed segment, a feed speed calculation unit that calculates a feed speed in the constant speed segment, and a distribution process unit that calculates the travel of a controlled axis for each control cycle so that acceleration/deceleration is applied in the acceleration/deceleration segments and the feed speed calculated by the feed speed calculation unit is achieved, and delay in the coordinate value with respect to the reference value based on the acceleration/deceleration control is corrected by using the feed speed calculated by the feed speed calculation unit.
