Method for auxiliary heating with pulse laser and machining with supersonic vibration

Abstract

The invention discloses a method for auxiliary heating with pulse laser and machining with supersonic vibration, specifically comprising the following steps: (1) installing a work piece 1 which is to be machined and selecting a proper tool 3, and installing the tool 3; (2) according to different technological parameters, adjusting laser impulse frequency to be integral multiple of supersonic vibration frequency; (3) adjusting the irradiating position of a pulsing laser 2, starting up a machine tool and presetting the tool; (4) sending 1-n beams of laser pulse by the pulsing laser 2 so that the laser pulse irradiates a part which is to be machined by the step 3, and heating up materials; (5) sending vibration by an ultrasonic frequency generator, driving the work piece (or the tool) to be vibrated at one time by an energy transducer to remove the materials of the heated part; (6) repeating the step 4 and the step 5 till that all the needed materials are removed; and (7) switching off the laser, retracting the tool, shutting down the machine tool, and replacing the old component to machine the next component. The invention solves the problem that fire-resistant and corrosion-resistant hard-brittle materials are difficult to machine.

Problems solved by technology

[0002] In the aerospace, missile and automobile industries, more and more hard and brittle materials with high temperature resistance and corrosion resistance are used, such as industrial ceramics, metal bond compounds, directionally solidified superalloys, etc. It is difficult to treat these hard and brittle materials with conventional machining methods processing, or although it can be processed, the tool wears quickly, the processed surface quality is not ideal, and the efficiency is low

Existing laser heating-assisted cutting methods require high laser power and low energy conversion efficiency

However, the existing vibration cutting processing methods can only process general hard and brittle quenching steel, stainless steel and other materials, and it is still difficult to effectively process ultra-hard and brittle materials such as industrial ceramics, metal bond compounds, and directionally solidified superalloys.
