Method for cutting screw thread-shaped twist structure of exhibiting workpiece, involves clearing workpiece away from tool in stop position, and making length of movement of tool to be smaller or equal to length of active cutting edge
The method involves moving a machine tool (2) only in axial direction with respect to rotational axis of a workpiece (1) during alternatively moving and stopping the workpiece. Length of the movement of the tool is smaller or equal to length of an active cutting edge and the workpiece is cleared away from the tool in stop position, so that the tool is continuously contacted with the workpiece by start-stop turning operations of the tool, material is cleared away from the workpiece and repositioning of the tool is located on the workpiece through the cutting edge in the stop position. An independent claim is also included for a device for cutting a screw thread-shaped twist structure of an exhibiting workpiece.
