NC Program Generating Apparatus Considering Power Saving

摘要

An NC program generating apparatus includes a standby state analyzing unit 12 analyzing an NC program to determine whether a block in which an operation unit is brought into a standby state is present, and when such a block is present, determining whether a power source 39, 45, 46 corresponding to the operation unit can be stopped at the time of execution of the block to specify a stoppable block, and a power operation code inserting unit 13 inserting an operation code for stopping the corresponding power source 39, 45, 46 at the time of execution of the stoppable block into the NC program and inserting an operation code for restarting the power source 39, 45, 46 after the execution of the block into the NC program.

主权项

1. An NC program generating apparatus considering power saving which generates, for an NC machine tool including a plurality of operation units each having a power source, an NC program for controlling the operation units, comprising:
a standby state analyzing unit which is connected to another NC program generating apparatus or an NC program storage unit storing therein an already generated NC program and which analyzes an NC program generated by the another program generating apparatus or the NC program stored in the NC program storage unit to determine whether, among a plurality of blocks forming the NC program, a block in which at least one of the operation units is brought into a standby state is present or not, and when a block in which at least one of the operation units is brought into a standby state is present, determines whether or not a power source corresponding to the operation unit can be stopped by interrupting or restricting power supplied to the power source at a time of execution of the block, thereby specifying a block at which the power source can be stopped; and a power operation code inserting unit which, when a block at which the power source can be stopped is specified by the standby state analyzing unit, inserts an operation code for stopping the power source at a time of execution of the block into the NC program and inserts an operation code for restarting the power source after the execution of the block into the NC program.
