Description

technical field [0001] The invention relates to a fixture device, in particular to a fixture device for processing cross-scale micro-features of a ball-end milling cutter, and belongs to the field of mechanical processing. Background technique [0002] With the in-depth research on bionic tribology, cross-scale micro-feature technology is proposed, which brings a new direction to the field of metal cutting. For titanium alloy machining, placing cross-scale micro-features on the tool surface can effectively improve the cutting performance, improve the tool wear during cutting, and obtain good surface quality of titanium alloy workpieces. At this stage, laser processing is usually used to fabricate cross-scale micro-features, and fiber lasers are the most widely used. However, when fiber lasers are used to process cross-scale micro-features, they can only be processed on the plane perpendicular to the laser beam, while ball-end milling cutters have arc-shaped surfaces, and fi...
