Abstract

See full text

An apparatus (100) and method (200) of contact machining having applications in profiling operations utilizes at least one static cutting tool (101) and turret (102) driven by rotary motion (103) about a support mechanism (109) for providing sufficient force to achieve deformation by controlled fracturing (523). This allows the separation of material from a workpiece (105) without imposing axial symmetry upon either the cutting tool (101) or the workpiece (105). The apparatus and method mitigates and/or eliminates the adverse effects of plastic deformation (504) while machining a wider range of shapes and materials with greater productivity and precision than existing methods of machining.
