ABSTRACT:
A method of feeding a tool to a predetermined depth in a workpiece in a machining process for producing at least one tooth surface on the workpiece. The workpiece being rotatable about a work axis and the tool being rotatable about a tool axis and includes at least one stock removing surface, The method comprises rotating the tool about the tool axis and contacting the rotating tool and the workpiece. The tool is fed relative to the workpiece along a feedpath to the predetermined depth wherein at least a portion of the feedpath is defined by a feed vector comprising at least first and second feed vector components. The first and second feed vector components are positioned in a plane defined by the work axis and the direction of the tool axis with the first feed vector component being substantially in the direction of the tool axis and the second feed vector component being substantially in the direction of the face width of the workpiece.
