Abstract
Abstract Execution format data required by a specific C-axis machining function such as a lead machining function are prepared by a custom macro, which has been stored in a ROM (102), based on data set by an operator through use of setting means such as a keyboard (104), and high-speed distribution data for controlling the machine tool are provided whenever necessary by setting parameters similar to those in ordinary milling. This makes it possible to realize a specific machining function which requires high-speed interpolation for machine movement command data.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A numerical control apparatus for controlling a machine tool having a machining function for movement of a tool relative to a workpiece along a rotational axis of the workpiece to machine the workpiece to a predetermined shape, comprising: data setting means for setting a relation between a rotational angle of the workpiece and a position of the tool relative to the workpiece; processing means for deciding an amount of tool movement and a rotational velocity of the workpiece in accordance with the relation; and drive control means for distributing at high-speed decided move command data to said machine tool.
Claim 2
Dependent Claim
99 words
A numerical control apparatus for controlling a machine tool having a machining function for movement of a tool relative to a workpiece along a rotational axis of the workpiece to machine the workpiece to a predetermined shape, comprising: data setting means for setting a relation between a rotational angle of the workpiece and a position of the tool relative to the workpiece; processing means for deciding an amount of tool movement and a rotational velocity of the workpiece in accordance with the relation; and drive control means for distributing at high-speed decided move command data to said machine tool.
Claim 3
Dependent Claim
37 words
A numerical control apparatus according to claim 1, further comprising graphic display means for displaying a program prepared on the basis of data inputted from said data setting means, and a machining path based on the program.
Claim 4
Dependent Claim
85 words
A numerical control apparatus according to claim 1, wherein said processing means includes: means for calling a custom macro program in which the set relation between the rotational angle of the workpiece and the position of the tool relative to the workpiece serves as a parameter; means for preparing, in accordance with said macro program, execution format data for deciding the amount of tool movement and the rotational velocity of the workpiece; and means for determining move command data necessary for a lead machining function.
Claim 5
Dependent Claim
55 words
A numerical control apparatus according to claim 1, further comprising: means for preparing execution format data for deciding the amount of tool movement and the rotational velocity of the workpiece; means for indirectly accessing the execution format data by setting a value of a variable in a custom macro instruction inserted in a machining program.
Claim 6
Dependent Claim
28 words
A numerical control apparatus according to claim 1, wherein said drive control means distributes the decided move command data based on the rotational velocity of said machine tool.
