摘要

PROBLEM TO BE SOLVED: To provide a controller and method allowing a sure operation of a machine tool. Ž

SOLUTION: This controller 18 for controlling the machine tool 23 driving a plurality of tools 12a, 12b, 12c has: a storage device 3 for storing movement limit values vamax, vbmax, vcmax, respectively by one, characteristic to the respective tools 12a, 12b, 12c, or the movement limit values vamax, aamax, vbmax, abmax, vcmax, acmax, respectively by a plurality, characteristic to the respective tools 12a, 12b, 12c; a target value generating unit 1 for generating a target value vsollfor controlling the movement of the tool 12a; and a limitation unit 2. The limitation unit 2 limits a target value vsoll, based on one or the plurality of characteristic movement limit values allocated to the tool 12a driven each time, and determines a plurality of target values vsollbnot to exceed the one or plurality of movement limit values, when moving the tool 12a.
