In numerically controlling a machine tool having a plurality of movable members controlled by respective programs, the programs are automatically altered to reliably avoid collision between the movable members. Labor and time required for the operator to alter the programs are reduced.

Method and apparatus for preventing tool collison

Method of creating NC program for pocket machining

For reliably and easily judging whether or not a cutting locus is correct, which locus has been set in a cutting locus or tool path control program, which program has a step of commanding the rotational angle of a rotary table carrying a workpiece and a step of commanding the locus of a cutter corresponding to each rotational angle commanding step. A rotational angle range for displaying the locus of the cutter is set through a keyboard or the like. A CPU causes a display only if the locus of the cutter is within the set range.

Numerical control apparatus

A numerical control method, and a numerical control device for subjecting a workpiece to a predetermined machining operation on the basis of a machining program. When a specified signal is generated during a machining operation under the control of the machining program, a subprogram, to which the numerical control device responds to execute processing in accordance with the specified signal, is stored in memory beforehand. Machining in progress under the control of the machining program is interrupted temporarily by the generation of the specified signal. At the same time, the subprogram is read from memory and is utilized in the processing of predetermined process steps. Following such processing, machining under the control of the machining program is resumed from the point of interruption or from an earlier point.
