Abstract
Abstract A numerical control system controls a plurality of axes with a plurality of channels (10, 20, 30). When a machining program for a first channel (10) is interrupted after a single block in response to a single block signal (6), the feeding of commands of a machining program for other channels (20, 30) is held. The machining programs are thereby executed in synchronism with each other. The machining processes are prevented from being unbalanced, and machining interference is avoided.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
75 words
A numerical control system for controlling a plurality of axes with a plurality of channels, comprising: means for receiving machining programs; means for receiving a single block signal; means for interrupting a machining program of a first channel in response to said single block signal being received; and single block control means for controlling the channels so that when the machining program for the first channel is interrupted, machining programs for other channels are suspended.
Claim 2
Dependent Claim
75 words
A numerical control system for controlling a plurality of axes with a plurality of channels, comprising: means for receiving machining programs; means for receiving a single block signal; means for interrupting a machining program of a first channel in response to said single block signal being received; and single block control means for controlling the channels so that when the machining program for the first channel is interrupted, machining programs for other channels are suspended.
Claim 3
Dependent Claim
23 words
A numerical control system according to claim 1, further comprising: means for providing said single block signal commonly to all of the channels.
Claim 4
Dependent Claim
23 words
A numerical control system according to claim 1, further comprising: means for providing respective single block signals to corresponding ones of the channels.
