ABSTRACT:
An active measurement and control system for a material cutting apparatus. The apparatus comprises a cutting tool which may be pivoted for cutting a workpiece in a cutting area at a selectable angle. The cutting area defines a datum plane, and a feed table with a shuttle vise is used to move the workpiece toward the cutting area. A controller controls the feed distance of the shuttle vise and the cutting angle of the tool in response to a signal from a sensor used for sensing a transverse dimension of the workpiece relative to the datum plane. In this way, the feed distance and cutting angle are adjusted to compensate for variations in the transverse dimension. This transverse dimension can include a displacement from the datum plane of a distal and/or proximate surface of the workpiece. A method of cutting a workpiece is also disclosed.
