A preceding-check processing sequence is provided separately from a machine-control processing sequence for an actual machine control, to make it possible to perform a collision check at an accurate position from an operation restart time of a machining program even when an operator interrupts an operation in the middle of the machining program or when the operator interrupts the operation as having detected a collision. This preceding-check processing sequence performs a collision possibility check ahead of an actual machine control. In this arrangement, there is provided a control-state synchronizing unit that matches a state of the preceding-check processing sequence with a state of the machine-control processing sequence during a period from when a machine stops until when the machine restarts an operation.

Numerical control method and apparatus therefor

A numerical control system improves safety when asynchronously operating systems are operated as a single control unit. A machine control system outputs a command generated by interpreting a program with a command number assigned thereto, sends it to a collision detection system, and receives check result data therefrom, whereby when the number of commands for which check result data are obtained is more than or equal to a preset second threshold, a command number assigned to the check result data is output when it is determined that there is no probability of collision. When the result of a check on the probability of collision for a command received from a linkage data sending and receiving section is returned, the collision detection system returns check result data to the linkage data sending and receiving section by assigning a command number given to the checked command to the check result data.
