Experimental Design Using the Taguchi Method for Determining the Optimal Parameters of the Cutting Process by Wire Cutting Machine

Abstract

The objective of this research is to study the surface roughness values obtained by adjusting the parameters of a wire-edged metal cutting machine by using the Taguchi experimental design method to analyze the parameters in cutting influences roughness and the material used in the experiment was SKD 11 mold steel. The workpiece was cut using the Wire Cutting Machine method. using electronic wire Brass rod size 0.25 mm. The workpiece was cut to a thickness of 10 mm. Experiments were conducted using the Taguchi method of cross-variables according to the experimental table . For the control factors studied there were 3. Factors include voltage, 2. IP-on-time electric current (On Time), 3. Wire speed. The results of the experiment found that the discharge current There is a significant influence on the surface roughness value for the discharge voltage and feed rate. It did not affect the surface roughness in this experiment and the experimental conditions that gave the lowest surface roughness values from this study were the voltage at 50 volts, the IP current value. On Time (On Time) at 12 amperes, wire speed at 6 mm./minute, which obtained the best surface roughness value at 3.346 micrometers (μm) from the experiment in increasing the electric current. A higher charge rate will result in an increase in the formation of a small surface roughness layer.
