Abstract
A numerical controller drives motors for respective axes of a machine tool by using an NC program and table-format data that command positions of those axes with reference to a position of a reference axis. The numerical controller generates, based on a movement command commanded by the NC program, interpolation data for an axis to be controlled by the movement command, generates, based on the table-format data, interpolation data for an axis to be controlled by the table-format data, and further generates interpolation data obtained by selection from or superposition of these two pieces of interpolation data.
Claims2
A numerical controller that drives a motor for each axis of a machine tool by using an NC program and table-format data that commands a position of each axis with reference to time or a position of a reference axis, the numerical controller comprising:
- a first interpolation data generation unit that generates, based on a movement command commanded by the NC program, first interpolation data that is interpolation data for an axis to be controlled by the movement command;
- a second interpolation data generation unit that generates, based on the table-format data, second interpolation data that is interpolation data for an axis to be controlled by the table-format data;
- and
- a third interpolation data generation unit that generates third interpolation data obtained by selection from or superposition of the first interpolation data generated by the first interpolation data generation unit and the second interpolation data generated by the second interpolation data generation unit.
