Abstract
Experimental results are presented concerning the characteristic features of mechanical treatment of a wide range of materials (Mo, W, Ti, ceramic materials, steels) preheated by laser radiation. Various physical phenomena which accompany laser assisted machining (LAM) are discussed: plasticization, structural and phase changes of materials, variation of friction conditions with temperature, effects of the laser plasma, etc. It is shown that under optimum conditions LAM significantly increases the quality of machining: roughness of the treated surface, depth and rate of cold working decrease; and shears and microcracks disappear. LAM permits: interrupted cutting of materials with increased strength characteristics; turning of soft and/or thin-walled materials; finishing of materials for which structural and phase changes beneath the cut line are not desirable. Generally, the productivity of machining can be increased up to 4–6 times.
