Using unconventional technology in stamping shop

Abstract

This article deals with technological possibilities in production of sheet metal in a stage of development-testing, when a shearing tool for serial production is not yet available. In the case of production of irregularly shaped functional samples unconventional technology can be used, especially WEDM (wire electrical discharge machining) method. This electroerosion technology of machining is still underutilized in stamping shop and its potential diffusion in small scale production can bring along significant economic savings during the stage of technical preparation of production. The issues of production of pressing tools necessary for cutting irregularly shaped blanks including optimisation of placing irregular cuttings in the plan at table or at roll sheet could thus be eliminated. By processing multiple layers of material at the same time, the unconventional technology allows producing a set of cuttings in one process.
