Abstract
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.
Claims3
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, the numerical controller comprising:
- an analyzer configured to generate 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;
- an interpolator configured to generate interpolation data based on the movement command data;
- and
- a servo controller configured to control a motor for driving the machine, based on the interpolation data.
