Numerical controller

Abstract

A numerical controller includes: a control unit that interprets a machining program including tool information for identifying a tool to control the axis of a machine tool; a feedback information acquisition unit that acquires, from the machine tool, feedback information indicating the position of the axis; a tool change information acquisition unit that acquires, from the machine tool, change information indicating that the tool has been changed; a synthesis information generation unit that synthesizes the feedback information with the tool information and change information acquired by the tool change information acquisition unit; a shape information storage unit that stores shape information indicating the shape of the tool; a machining simulation unit that executes workpiece machining simulation on the basis of the synthesis information and the shape information; and an output unit that outputs machined shape information indicating the shape of the machined workpiece.
