ABSTRACT:
A tool holder constituting an adaptive machining control system to automatically manipulate tool rake angle using in-process force feedback. The tool holder includes a rotatable member for holding a cutting member which cuts a workpiece, a motor to rotate the holding member, and a sensor and control logic to sense cutting forces and activate the motor to rotate the holding member and change the tool rake angle. The cutting member is held so that it rotates about an axis through its cutting tip to change the rake angle without varying the depth of cut on the workpiece. In an alternative embodiment, a manually operated tool holder is manipulated to similarly rotate a cutting member to vary the rake angle.
