SYSTEM AND METHOD FOR AUTOMATED MACHINING OF TOOTHED MEMBERS

摘要

A system and method for machining a workpiece to provide a toothed member having a desired tooth pattern. A cutting tool machines the workpiece to a first depth, thereby forming a semi-finished tooth pattern, the first depth less than a full depth to which the workpiece is to be machined to provide the desired tooth pattern. Dimensions of the semi-finished tooth pattern are acquired and compared to nominal dimensions. If the acquired dimensions are not within a tolerance of the nominal dimensions, the geometry of the cutting tool is modified for correcting deviations of the acquired dimensions from tolerance and the workpiece further machined by the modified cutting tool. Once the dimensions of the semi-finished tooth pattern are within tolerance, the workpiece is machined to the full depth for providing the desired tooth pattern.

1. A computer-implemented method for machining from a workpiece a toothed member having a desired tooth pattern, the workpiece machined using a cutting tool of a numerically controlled machine, the method comprising:
causing the cutting tool to machine the workpiece to a first depth to provide a semi-finished tooth pattern, the semi-finished tooth pattern created according to a geometry of the cutting tool, the first depth less than a full depth of the desired tooth pattern; acquiring dimensions of the semi-finished tooth pattern; comparing the acquired dimensions to nominal dimensions of the semi-finished tooth pattern and determining whether the acquired dimensions are within a predetermined tolerance of the nominal dimensions; if the acquired dimensions are not within the predetermined tolerance of the nominal dimensions, causing the geometry of the cutting tool to be modified for correcting deviations of the acquired dimensions from the tolerance, and causing the modified cutting tool to machine the workpiece to bring the dimensions of the semi-finished tooth pattern within the tolerance; and causing the workpiece to be machined to the full depth to provide the desired tooth pattern.
