Abstract
A machining apparatus for machining a workpiece by moving a tool in direction relative to the workpiece comprises, tool moving means for moving the tool in the direction relative to the workpiece, tool movable range setting means for setting a movable range for the tool to inhibit the workplace from exceeding a reference size by inputting the reference size, and halting means for halting a movement of the tool when a position of said tool exceeds the tool movable range set by said tool movable range setting means.
Claims7
A machining method for machining a workpiece by manual control comprising the steps of:
- (a) setting an oversize amount which is an amount of machining remaining to be performed on the workpiece to provide a strict tolerance;
- (b) tentatively setting a movable range of a tool based upon said oversize amount and a desired size of the workpiece;
- (c) moving the tool in a direction relative to the workpiece;
- and
- (d) halting movement of the tool in the event that a position of the tool exceeds said movable range.
