Establishment of laser beam machining technique and its application to electrical equipments. Laser setsudan giho no kakuritsu to denryoku kiki eno oyo

Abstract

A 1kW CO {sub 2} laser beam machine was applied to the cutting of parts of electrical equipments, such as transformer, breaker, gas turbine, etc., which are typical many-form small-production equipments. Steel less than 9mm {sup t} was used as a subject material. An empirical formula for effective cutting of steel was presented. For cutting stainless steel, a fine cut method was employed, in which thermally affected layer was small. The outline of 1kW CO {sub 2} laser beam machine, its specification, and laser beam machining were illustrated. Experimental data riquired for introduction to the production line were presented, concerning the laser beam power, the dependence of laser beam power density, the relationship between steel plate thickness and laser beam energy density, and the method for decreasing thermal effect. Comparing on production costs between turret punch press and laser beam machining, it was shown that the latter was superior to the former in the case production was less than 500. Thus, the laser beam machining technique for production field was established. 3 refs., 11 figs., 2 tabs.
