ABSTRACT:
A cutting tool insert is mounted on a flexure member that is mounted on the end of a boring bar. The construction of the flexure member is such that it is compliant along a radial axis perpendicular to the direction of tool advancement, but relatively stiff along a feed axis in the direction of tool feed, and along a cutting axis in the direction of tool rotation. Any displacement of the flexure member and cutting tool insert as a result of workpiece engagement or boring bar deflection is sensed by laser detectors. Signals from the laser detectors are coupled to a computer that rotates with the boring bar and are used to provide feedback signals to an actuator in contact with the flexure member. The actuator displaces the flexure member to correct the position of the tool insert.
