Optimization of gap of width and surface roughness in wire cut EDM of AISI O1 using the Taguchi - fuzzy method

The aim of this paper is to optimize of kerf (gap of width) and surface roughness in wire cut EDM of AISI O1 using Taguchi fuzzy method. The quality characteristics of gap of width and surface roughness are lower the better. The machining process variables is considered on time, wire feed, servo vol...

Description
Summary:The aim of this paper is to optimize of kerf (gap of width) and surface roughness in wire cut EDM of AISI O1 using Taguchi fuzzy method. The quality characteristics of gap of width and surface roughness are lower the better. The machining process variables is considered on time, wire feed, servo voltage, and arc on time. The machining variables studied has three levels and the experiment design used L9 orthogonal array with two replications. Taguchi fuzzy is used to investigate the performance characteristic in wire cut EDM AISI O1. The results of this experiments confirm that fuzzy logic based Taguchi increase significantly the performance characteristics of quality in wire cut EDM. The experiment results shows that on time of 2 μs, wire feed of 8 mm/sec, servo voltage of 55 Volt and arc on time of 5 A are the optimum value for wire cut EDM of AISI O1.
