A numerical controller configured for simultaneous control such as to cut a workpiece in order in the direction of a rotary axis by a plurality of tools, in a machine having a plurality of cutter holders fitted individually with the tools and capable of lathe turning, generates movement command data for locating the plurality of tools so as to cut the workpiece with the same depth of cut and controlling respective relative speeds and relative positions of the plurality of tools so that respective cutting points of the tools move back and forth in order; generates interpolation data based on the movement command data; and controls a motor for driving the machine, based on the interpolation data.

Numerical controller for continuous cutting control

A numerical controller includes a division setting unit which sets division information for dividing a machining region into a plurality of areas, an area division unit which divides a machining region into a plurality of areas based on division information, a program division unit which generates divided programs respectively used for machining control in the areas, an area coordinate system setting unit which sets a virtual coordinate system in the plurality of areas, and an operation precision setting unit which sets operation precision, and performs internal operation for controlling an operation of a machine in accordance with the virtual coordinate system and the operation precision to control each axis of the machine.

Numerical controller enabling increase in number of analysis digits of program instruction

A numerical controller that shortens time required for transferring control of a spindle between control systems. When the spindle control command is included, the command is carried out and information on designation of the spindle, commanded rotational velocity and direction is stored in a case of a velocity control mode, and information on designation of the spindle, commanded rotational position and velocity is stored in a case of a position control mode. When a command to cancel the control of spindle is read, the control of the designated spindle and also the stored information on the control status of the spindle are transferred to the other control system. A command to acquire the control of the spindle is read in a machining program for the other control system, the control of the designated spindle is started by the other control system according to the transferred control status of the spindle.
