Patent ID: 8776357

Claim:
A method of machining a workpiece, comprising: securing the workpiece in a workpiece retainer, the workpiece retainer defining a machining area and being supported for rotation about a C-axis; securing a first cutting tool in a first tool retainer disposed on a first side of the machining area, the first tool retainer being supported for movement along an X-axis and a Z-axis; securing a second cutting tool in a second tool retainer disposed on a second side of the machining area substantially opposite the first side of the machining area, the second tool retainer being supported for movement along an XA-axis substantially parallel to the X-axis and a ZA-axis substantially parallel to the Z-axis; simultaneously controlling operation of the workpiece retainer, the first tool retainer, and the second tool retainer with a controller including a single command line for controlling movement of the workpiece retainer relative to the C-axis, movement of the first tool retainer relative to the X-axis and the Z-axis, and movement of the second tool retainer relative to the XA-axis and the ZA-axis, wherein the first and second tool retainers are controlled so that the respective first and second cutting tools simultaneously engage the workpiece.
