Methods and apparatus for generating control data for the formation of a tooth flank by milling a workpiece on a machine tool

摘要

A disclosed example method for generating control data for the formation of a tooth flank by milling a workpiece on a numerically controlled machine tool with at least 5 axes, at a universal machine tool, through successive passes with a milling cutter on the machine tool based on generated control data involves defining a geometry of a tooth flank, determining a contact pattern area on the predefined tooth flank geometry, determining parameters to vary the predefined tooth flank geometry, and generating control data on the basis of tooth flank geometry modified based on the defined contact pattern area and of the defined parameters.

1. A method for generating control data for the formation of a tooth flank on a workpiece at a numerically controlled machine tool with at least 5 axes by using a milling cutter, the method comprising:
defining a tooth flank geometry, defining a contact pattern area on the predefined tooth flank geometry, the contact pattern area being a two-dimensional partial area of a two-dimensional surface area of the predefined tooth flank geometry, defining parameters to vary the predefined tooth flank geometry, modifying the predefined tooth flank geometry to determine a modified tooth flank geometry based on the defined contact pattern area and the defined parameters, and generating the control data on the basis of the modified tooth flank geometry, wherein the generated control data is configured to control the numerically controlled machine tool to produce the tooth flank on the workpiece according to the modified tooth flank geometry by milling through successive passes of the milling cutter along machining paths successively or in lines based on the generated control data.
