Description

technical field [0001] The invention relates to the technical field of laser-assisted processing, in particular to a laser compound ultrasonic-assisted grinding processing unit and method suitable for curved surface components. Background technique [0002] High-performance alloys (titanium alloys, tungsten alloys, etc.), hard and brittle materials (optical glass, laser crystals, engineering ceramics, etc.) and composite materials (particle-reinforced metal matrix composites, fiber-reinforced ceramic matrix composites, etc.) Typical difficult-to-machine materials. Laser composite machining is considered an effective way to process difficult-to-machine materials. During laser composite processing, the high-power laser beam is focused on the surface of the workpiece in front of the cutting edge, so that the strength and hardness of the workpiece material change at high temperatures, so that ordinary tools can be used for processing, which greatly reduces cutting resistance an...
