Numerical controller and machining system

Abstract

The objective of the present disclosure is to provide a means capable of performing clamping and unclamping operations at appropriate times. In a machining system 1 provided with a rotary table device 10, a numerical controller 30 according to an embodiment of the present disclosure controls the rotary table device 10 in accordance with a machining program including a plurality of statements, said rotary table device 10 including a table 11, drive mechanisms 12, 13 that rotate and position the table 11 around an axis, and clamping mechanisms 14, 15 that restrain the rotation of the table 11. The numerical controller 30 is provided with: an unclamping addition unit 35 which adds an unclamping operation for releasing the restraint of the table 11 immediately before execution of a table rotation statement that is included in the machining program and that specifies the operation of the drive mechanisms 12, 13; and a clamping addition unit 36 which adds a clamping operation for restraining the table 11 immediately after the execution of the table rotation statement.
