Method for rough machining of workpiece with multi-axis milling machine, involves executing roughing of workpiece by material of ablation layers along machining path with variable employment of tool

摘要

The method involves predetermining a three-dimensional target surface in a workpiece recess. An upper boundary surface (6) is provided at a place of the recess by an output surface of a workpiece. Demolition layers are arranged one above other between a floor space (4) and the upper boundary surface. Roughing of the workpiece is executed by material of ablation layers along a machining path (10) with a variable employment (9) of a tool. Auxiliary surfaces between the floor space and the upper boundary surface are managed.
