METHOD AND DEVICE FOR MACHINING A ROTARY TOOL WITH A PLURALITY OF CUTTING BODIES

摘要

The invention relates to a device (20) and a method (22) for machining a rotary tool (21) working surface (23) which has a plurality of cutting bodies (24). The rotary tool (21) can be driven about a rotational axis (R). The cutting bodies (24) can form a geometrically defined or a geometrically undefined tool blade. Preferably, the cutting bodies are statically distributed on the working surface (23). The actual enveloping surface (HF) of the working surface (23) is ascertained by means of an optical measuring arrangement (29). Additionally, at least one other target variable (GS) is detected which describes a microscopic parameter of the working surface (23). The actual variable (GI) corresponding to each specified target variable (GS) is detected by means of the measuring arrangement (29), and the deviation between the target variable (GS) and the actual variable (GI) is determined. If the actual enveloping surface (HF) lies outside of a specified target enveloping area (HR) or if a deviation (D) between an actual variable (GI) and the corresponding target variable (GS) is unacceptably large, selected first and/or second cutting bodies (24a, 24b) are machined and/or removed by means of a laser device (35). The method is carried out cyclically until the rotary tool (21) satisfies all the specifications.
