A machining operation generating unit analyzes a program in accordance with a machining program stored in the storage unit and causes the machine tool to perform a normal machining operation. A chip removal operation generating unit outputs an instruction for rotating a main shaft in the reverse direction to the interpolation unit after a cutting machining performed by the machine tool ends. The chip removal operation generating unit rotates the main shaft in the reverse direction for a predetermined time.

A back spotfacing system having a machining apparatus with a through-hole cutter tool. The tool has an elongate member movable to coaxially extend through a hole in a workpiece from a first side of the workpiece, the workpiece coupled to the apparatus. The tool has a cutter element pivotal between a stowed position on the elongate member, a contact position with an inner surface of the hole, and an extended position extending radially from the elongate member. In the extended position, the cutter element extends to machine and back spotface a surface on a second side of the workpiece opposite the first side. The system has a power system for powering the apparatus and tool, and a measurement system coupled to the apparatus for measuring one or more hole exit positions of the cutter element and one or more surface contact positions of the cutter element on the surface.

A tooling system that includes a drive unit configured to provide rotational force to a tool member. The tool member is attached at a mount on the drive unit. A camera associated with the drive unit is aligned to capture a target on the tool member. The data is sent to a controller that identifies the tool member based on the target. The controller determines whether the tool member is correct for performing an operation on a work piece. If the tool member is correct, the controller may set one or more operating parameters on the drive unit. If the controller determines that the tool member is not correct, the drive unit is disabled. Further, a signal may be sent to inform an operator of the issue.
