Method for manufacturing bent tooth flank at bevel wheel, has extending part of reference point lines, determining processing trajectory based on flank line set and processing workpiece by moving machining tools along trajectory

摘要

The method involves providing reference point line sets with reference point lines that have reference points. The sets are positioned with respect to a reference point of the workpiece. A flank line set is formed by the determination of extension portions. A part of the reference point lines is extended. A processing trajectory is determined based on the flank line set. A workpiece (23) is processed by moving material removal-machining tools (26) along the trajectory, where a processing line set and the flank line set are arranged in different planes. An independent claim is also included for a machine tool for manufacturing a bent flank.
