Abstract
A numerical controller for controlling a multi-axis machine calculates an axis-dependent translation error amount and an axis-dependent rotation error amount based on a command axis position. Translation and rotation compensation amounts are calculated based on the axis dependent translation and rotation error amounts, respectively. The translation and rotation compensation amounts are added to command linear and rotary axis positions, respectively. Three linear axes and three rotary axes are driven to the added positions, individually. Thus, there is provided a numerical controller that enables even machining with a side face of a tool or boring to be in commanded tool position and posture (orientation) in the multi-axis machine.
