摘要： The invention relates to a method for machining flat surfaces (30) of a workpiece (32) using a tool (10), in particular a milling tool, which is moved in a collision-free and laterally inclined manner (α) relative to a flat surface (30) such that a contact point (34) is guided on the flat surface (30). The flat surface (30) is machined using a tool (10) with a cutting contour (18), which has a conically convex design, on one flank (16) of the tool (10) at a pivot angle (ß) parallel to the flat surface (30) in order to prevent a one-sided collision completely by the tool (10) and at at least two different pivot angles (ß, ß′) parallel to the flat surface (30) in order to prevent a two-sided collision by the tool (10), wherein the flat surface (30) is separated into at least two machining segments (44, 44′, 44″), each of which is assigned an individual pivot angle (ß, ß′) of the tool (10) in order to prevent a two-sided collision.

The conically convex milling cutter (10) comprises a shank (12) and a conically convex milling cutter portion (14) connected at the end to the shank (12) directly or through a transition (16). The conically convex milling cutter (10) has a first and a second cutting area (24, 26), wherein the first cutting area (24) is provided on the shank (12) or/and at the transition (16), and wherein the second cutting area (26) is provided on the conically convex milling cutter portion (14). The method comprises the following steps: A) roughing a blank portion (30) using the conically convex milling cutter (10), wherein the latter is inclined relative to a current feed direction (40) at a reference point (38) of the conically convex milling cutter (10) within a first machining angle range (α1, β1) such that machining is performed with the first cutting area (24) of the conically convex milling cutter (10), wherein the second cutting area (26) remains passive during machining, and B) finishing at least a part of the rough blank portion (46) using the conically convex milling cutter (10), wherein the latter is inclined relative to the current feed direction (40) at the reference point (38) of the conically convex milling cutter (10) within a second machining angle range (α2, β2) in such a way that machining is performed with the second cutting area (26) of the conically convex milling cutter (10), wherein the second cutting area (26) engages with the blank (30).

摘要： A method is provided for the material-removing machining of fillets on a workpiece by means of a tool, more particularly a milling tool, which is guided over a fillet at a contact point. The invention is characterized in that the fillet is machined by means of a tool comprising a conical-convex cutting edge on a flank of the tool, wherein the tool, with the contact point on the conical-convex cutting edge, moves along at least one contact path running in the longitudinal direction of the fillet and the tool is inclined sideways in relation to the at least one contact path on the fillet such that a substantially sickle-shaped material engagement is formed in front of the contact point in the movement direction of the tool.
