Abstract
The operation of positioning a machine by a numerical control apparatus is completed when it is determined that a current feedback value of a motor, which varies in response to deflection of the machine, is in a given range.
Claims8
A numerical control method for determining whether a positioning operation of a machine has been completed, said method comprising:
- (a) receiving machining information for a block of a machining program to be executed;
- (b) interpolating the machining information for the block;
- (c) determining whether an in-position check is to be performed for the machining information;
- (d) receiving a current feedback value when the in-position check is to be performed;
- (e) determining whether the current feedback value is within a given range;
- and
- (f) completing the position operation of the machine when the current feedback valve is determined to be within the given range, by repeating steps (a)-(e) until all the blocks of the machining program have been executed.
