The workpiece is clamped on the tool holder of the work spindle of the machine tool, the tool is clamped in the clamp of the machine tool, and the workpiece clamped in the tool holder of the work spindle is controlled in a program-controlled manner in relation to the tool clamped in the clamp for removing material from the workpiece.
摘要:
A disclosed example method for generating control data for forming a tooth of a spur gear toothing which has an intended widthwise crowning by milling a workpiece at a numerically controlled machine tool having at least 5 axes, at a universal machine tool, by successively moving a milling cutter of the machine tool along a plurality of machining paths based on the generated control data, involves providing a tooth flank geometry of at least one tooth flank of the tooth of the spur gear toothing. The method also involves determining parameters for specifying a change of the provided tooth flank geometry according to the intended widthwise crowing of the tooth. In addition, the method involves generating control data based on a tooth flank geometry which is changed based on the determined parameters, wherein the changed tooth flank geometry corresponds to a tooth flank geometry of the tooth having the intended widthwise crowing.
