Abstract: An electronic control system is programmed to control movement of a cutting tool relative to a rotating workpiece. After engagement of the stock, the tool is controlled to follow a curved path until the cutting surface of the tool reaches a predetermined depth of cut in the stock. The tool is then controlled to follow a straight/linear path, with the cutting surface of the tool engaged with the stock at said predetermined depth of cut.

The feed rate as the tool rolls into cut is programmed to vary in relation to an arc of engagement between a cutting surface of the cutting tool and the stock into which the cutting tool is being moved.
