A method for analyzing an overcutting defect of a machining process comprises steps as following. A machining code is executed to generate a cutting face, wherein the cutting face comprises a plurality of machining paths. A specified machining path is defined from the plurality of machining paths and a specified node is set on the specified machining path. A sectional plane passing through the specified node is calculated. A plurality of intersection points between the sectional plane and the other machining paths which are different from the specified machining path are obtained. A first adjacent intersection point a second adjacent intersection point are specified from the intersection points. A connection line located between the first adjacent intersection point and the second adjacent intersection point is obtained. A distance between the specified node and connection line is calculate and the distance is defined as an overcutting amount of the specified node.

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 () 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 () 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 (, ) 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 (, ) of the tool (10) in order to prevent a two-sided collision.
