Abstract
Abstract A numerical control can be performed on one or more independently controllable objects on the basis of existence of such objects and the control itself is performed selectively on the axis and other objects which are not axes. Therefore, it is possible to control one to all of various objects which are to be operated simultaneously independently, by means of a single numerical control apparatus. Thus, a plurality of objects can be controlled independently from other objects, resulting in high producibility of products.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A numerical control apparatus for controlling at least one pair of a first object (7) having an axis to be controlled by an axis control instruction and a second object (8) having a variable member other than an axis to be controlled by an auxiliary control instruction, comprising: a control instruction allocation circuit (9) for deciding an existence of said pair of objects and allocating said axis control instruction and said auxiliary control instruction thereto, and a control portion (3a) responsive to said axis control instruction and said auxiliary control instruction for controlling said pair of objects.
Claim 2
Dependent Claim
97 words
A numerical control apparatus for controlling at least one pair of a first object (7) having an axis to be controlled by an axis control instruction and a second object (8) having a variable member other than an axis to be controlled by an auxiliary control instruction, comprising: a control instruction allocation circuit (9) for deciding an existence of said pair of objects and allocating said axis control instruction and said auxiliary control instruction thereto, and a control portion (3a) responsive to said axis control instruction and said auxiliary control instruction for controlling said pair of objects.
Claim 3
Dependent Claim
19 words
The numerical control apparatus as claimed in claim 1, wherein said control portion selectively controls only said first object.
Claim 4
Dependent Claim
19 words
The numerical control apparatus as claimed in claim 1, wherein said control portion selectively controls only said second object.
Claim 5
Dependent Claim
47 words
The numerical control apparatus as claimed in claim 1, wherein said control portion comprises an axis/auxiliary instruction control discrimination circuit (10) capable of selecting either or both of said axis control instruction and said auxiliary control instruction such that an arbitrary combination of controls can be performed.
Claim 6
Dependent Claim
53 words
The numerical control apparatus as claimed in claims 1, 2, 3 or 4, wherein a plurality of pairs of said first object and said second object are provided and a corresponding number of said control portions operate to select one or more of said pairs and control each said pair simultaneously and separately.
