Problems solved by technology

[0006] Known grinding methods for sharpening or dressing such rotary tools also have the disadvantage that the sharp points and edges of the cutting body are worn and thus negatively affect the cutting effect of the rotary tool

Embodiment Construction

[0053] The invention relates to a device 20 for machining a rotary tool 21 and a method 22 for machining the same. The rotary tool 21 is a tool used for cutting processing. The rotary tool 21 is rotatably driven about an axis R of rotation. On its periphery, the rotary tool 21 has a working surface 23 on which at least one tool cutting edge is arranged, which is rotatably driven about an axis R of rotation. A plurality of cutting bodies 24 each with one or more cutting body cutting edges 43 forms, for example, a geometrically undefined cutting pocket. The cutting bodies 24 can be arranged statistically distributed in the region of the working surface 23 of the rotary tool 21 . As an alternative to this, it is also possible to place the cutting body 24 in a precisely defined position, as in Figure 10 in or in Figures 12 to 14 shown in . The engagement contours of the cutting bodies 24 overlap or intersect during the rotation of the rotary tool 21 and thus define the tool...

Abstract

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.

Description

technical field [0001] The invention relates to a method and a device for machining a rotating tool with a large number of cutting bodies. The rotary tool is rotatably drivable about an axis of rotation and has a geometrically undefined cutting cavity or a geometrically defined tool edge formed by the cutting body. A rotating tool with cutting bodies forming a geometrically undefined cutting cavity can be, for example, a grinding wheel or a dressing tool. Tools whose cutting body forms a geometrically defined tool edge are, for example, milling, drilling or grinding tools. Background technique [0002] Especially for precision tools it is important to achieve a very precise contour and very precise radial or axial runout of the rotary tool. Since machining accuracies of a few microns are to be achieved with these tools, inaccurate manufacture or wear phenomena of the rotary tool can lead to impermissible tolerance deviations. When the cutting body consists of a very hard ...
