An automatic method of trimming portions of a workpiece such as a casting includes moving a trimming tool along the contour of the workpiece while imparting linear or rotary cutting motion to the tool, detecting the deflection of the tool as it follows the contour, and using signals representative of the deflection detection to control the contour-following tool motion. Apparatus for performing this method includes proximity detectors in the tool support or elastic deformation sensors such as strain gauges, in various embodiments. The tool itself acts as a pattern follower as well as the trimmer, using the workpiece as the pattern.
