Abstract
In a method for cutting freeform surfaces, a workpiece is cut by a cutting tool such that a desired freeform surface may be achieved, the cutting tool for cutting purposes being moved along at least one defined cutting path relative to the workpiece. A cutting tool is used, the tool head of which has a greater radius than a tool shank of the cutting tool.
Claims8
A method, comprising:
- producing one of (a) first cutting paths and (b) ancillary cutting paths with a spherical cutter having a tool head radius corresponding to a tool shank radius, and producing second cutting paths for the cutting tool from the one of (a) the first cutting paths and (b) the ancillary cutting paths, and
- cutting freeform surfaces on a workpiece by a cutting tool to achieve a desired freeform surface, the cutting tool including a tool head and a tool shank, the tool head having a greater radius than the tool shank, the cutting including moving the cutting tool along at least one defined cutting path relative to the workpiece.
