Numerical controller operating from table-format data

A numerical controller performing an operation based on table-format data by using table-format data that designates the position of each control axis or an auxiliary function on the basis of a time, the position of an axis, or the position of a spindle thereby to control the position of a control axis or an auxiliary function in synchronization with the time, the position of an axis, or the position of the spindle, which provide references, the numerical controller performing an operation based on table-format data, comprising:

• a table management unit that selects a plurality of tables of table-format data used for a machining operation;
• a table readout unit that reads out the plurality of tables of table-format data selected by the table management unit;
• a distribution processing unit that generates, for each of the tables of table-format data, distributed interpolation data for an axis to be controlled on the basis of the table-format data according to the plurality of tables of table-format data read out by the table readout unit;
• a selection and superimposition unit that selects and superimposes, for each control axis, the plurality of tables of distributed interpolation data generated by the distribution processing unit;
• and
• a motor control unit that controls the position of the control axis on the basis of the superimposed distributed interpolation data.
