  • Patent number: 4580225
    Abstract: A method is disclosed for machining multiple entry threads on a workpiece. The preferred steps of the method are preferably carried out in conjunction with a computer-based numerical control system. The method includes the steps of: determining the angular position of the workpiece as it is being rotated by a machine tool spindle; determining the desired separation of thread entry points; specifying the angular position of the workpiece at the start of tool motion for cutting a first thread on the workpiece, the angular position being stored as a reference angle; and for each subsequent thread, starting motion of the cutting tool from the first thread starting point whenever the angular position of the workpiece is displaced from the reference angle by an amount equal to the desired entry point separation from the first entry point, the motion being maintained along the identical path used to cut the first thread.
