Abstract
Abstract A numerically controlled machining system in which plural simultaneous machining operations can be carried out. A display is effected in matrix form of all combinations of machining operations which can be performed by various tools of the machining system, for instance, a lathe. The operator can readily select among the various possible combinations to make maximum use of the available machining tools.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
114 words
A numerically controlled machining system including a machining device having a plurality of turrets for performing plural machining operations, said machining device being controlled by a numerical control device, comprising: means for storing in a memory of said numerical control device data indicating combinations of possible simultaneous operations of said turrets; means for displaying, in response to the data stored in the memory, an image including indications of permitted and non-permitted combinations of simultaneous operations of two of said turrets; means for modifying said displayed indications and for rewriting said memory in accordance with said modifications; and means for determining an order of performing machining operations in response to the content of said memory.
Claim 2
Dependent Claim
114 words
A numerically controlled machining system including a machining device having a plurality of turrets for performing plural machining operations, said machining device being controlled by a numerical control device, comprising: means for storing in a memory of said numerical control device data indicating combinations of possible simultaneous operations of said turrets; means for displaying, in response to the data stored in the memory, an image including indications of permitted and non-permitted combinations of simultaneous operations of two of said turrets; means for modifying said displayed indications and for rewriting said memory in accordance with said modifications; and means for determining an order of performing machining operations in response to the content of said memory.
