Title:
METHOD AND DEVICE FOR MILLING FREEFORM SURFACES
Document Type and Number:
WIPO Patent Application WO2005005082
Kind Code:
A3
Abstract:
The invention relates to a method and a device for milling freeform surfaces. During milling of 5 axes, a work piece is milled by a tool and/or a miller, in order to produce a desired freeform surface. Said tool is displaced, with respect to the work piece, along at least one tool path and/or milling path defined by support points. According to the invention, a tool vector is defined for each support point of the tool path in the form of forward angles and setting angles. A normal vector is determined for each support point from the forward angles and setting angles, and from a drive vector determined for each support point. The normal vector in each support point of the tool path is used for 3D radius correction in order to compensate for measuring deviations of the miller.
