Abstract
The nominal configuration of a workpiece is stored in a multiaxis numerically controlled machine. The workpiece is probed in the machine to determine an offset from the nominal configuration. The workpiece is then shifted by the offset to correspond with the nominal configuration. The workpiece is then machined according to the nominal configuration.
Claims22
A method of machining a workpiece in a multiaxis numerically controlled machine comprising:
- storing in said machine a nominal configuration of said workpiece deined by a plurality of contour points represented by coordinates of said multiple axes;
- probing said workpiece in said machine to determine a common offset of said workpiece from said nominal configuration;
- shifting said workpiece by said common offset to correspond with said nominal configuration;
- and
- machining said shifted workpiece according to said nominal configuration while maintaining said common offset.
