A distance measurement during laser-assisted milling to the blank surface for the purpose of laser pre-tensioning for guaranteed ductile tooth entry before and during the milling process

摘要

A distance measurement during laser-assisted milling to the blank surface for the purpose of laser pre-tensioning for guaranteed ductile tooth entry before and during the milling process, characterized in that the cooling medium (MK2 Fig. 1) guided parallel to the laser beam through the milling spindle and the tool exits at the reference tooth, and the bottleneck between the tool and the workpiece surface creates a pressure peak (8) which signals a mass for the tooth entry which is permanently corrected via the active C-axis point for guaranteed ductility.
