Abstract
A machining control device for a machine tool reads a machining program for each predetermined reading unit, controls a machining operation of a machine tool based on the read machining program, performs a machining simulation by sequentially reading out the read machining program, and discriminates a buffer state based on the result of the machining simulation. If insufficient buffering is discriminated in the control of the machining operation, control is performed to stop machining on a non-machining path short of the position of occurrence of the insufficient buffering.
Claims11
A machining control device for a machine tool configured to perform machining control for a workpiece using a machining program including a machining path and a non-machining path, comprising:
- a machining program acquisitor configured to read the machining program for each predetermined reading unit;
- a machining controller configured to control a machining operation of the machine tool based on the machining program read by the machining program acquisitor;
- a simulation executor configured to perform a machining simulation by sequentially reading out the machining program read by the machining program acquisitor;
- and
- a buffer state discriminator configured to discriminate a buffer state of the machining program acquisitor, based on the result of the machining simulation,
- the machining controller being configured to perform control to stop machining on the non-machining path short of the position of occurrence of insufficient buffering if the insufficient buffering is discriminated by the buffer state discriminator.
A machining control method for a machine tool configured to perform machining control for a workpiece using a machining program including a machining path and a non-machining path, comprising:
- reading the machining program for each predetermined reading unit,
- in controlling a machining operation of the machine tool based on the read machining program, the method further comprising:
- performing a machining simulation by sequentially reading out the read machining program and discriminating a buffer state of the machining program based on the result of the machining simulation;
- and
- stopping machining on the non-machining path short of the position of occurrence of insufficient buffering if the insufficient buffering is discriminated.
