Method for machining a workpiece by means of a cutting tool on an NC-controlled machine tool

摘要

The invention relates to a method for machining a workpiece 1 by means of a cutting tool 2 on an NC-controlled machine tool, in which the tool 2 is moved relative to the workpiece 1 along tool paths 3, which are formed by a series of support points N. wherein the enveloping body 4 resulting from the rotation of the tool 1 has substantially point contact in a contact point 6 when machining the workpiece 1 with the surface 5 of the workpiece 1, characterized in that the data of the interpolation point N is the data of the respective contact point 6 of the enveloping body 4 are determined and that a correction of the data of the support point N takes place along a surface normal 7 in the contact point 6.
