Originální abstrakt

Unconventional technology of wire electrical discharge machining (WEDM) is essential in manufacturing precise parts for the aviation, automotive military or medical industry. Precision of dimensions and shapes of machined parts is preserved because of the ability to machine the material after the final heat treatment. However efficient and precise machining also depends on the ability to manufacture as small radiuses as possible, which can be achieved by minimizing the width of kerf. To minimize the width of kerf “Half central compositeresponse surface design” plan of experiment considering gap voltage, pulse on time, pulse off time, wire feed and discharge current was implemented. Measurement system analysis (MSA) was computed for the width of kerf measuringsystem and based on its results mathematical model of the average width of kerf was found. Optimal setting of statistically significant machine parameters to minimize the average with of kerf was deducted from this model.
