PERFORMANCE EVALUATION AND DEAR BASED OPTIMIZATION ON MACHINING LEATHER SPECIMENS TO REDUCE CARBONIZATION

Abstract

Due to the variety of benefits over traditional cutting techniques, the usage
of laser cutting technology has risen substantially in recent years. The hot wire
machining can cut the leather in the required shape by controlling through the
wire by generating thermal energy. In the present study, an attempt has been
made to investigate the effects of performance measures in hot wire machining
process on cutting leather specimens. Carbonization and material removal rate
were considered as quality indicators. Burning leather during machining might
cause carbon particles, reducing product quality. Minimizing the effect of carbon
particles is crucial for assuring operator and environmental safety, health, and
product quality. The hot wire machining can efficiently cut the specimens by
controlling current through it. Taguchi- DEAR based optimization was also
performed in the process which results in a required Carbonization and material
removal rate. Using the DEAR approach, the optimal parameters of the present
study were found with 3.7% of prediction error accuracy.
