Experimental investigation of process parameters for WEDM of Ti-6Al-4V/TiN composites
Source abstract
Abstract
Abstract Ti-6Al-4V alloys are difficult-machine materials. These alloys are extensively used in medicine, chemical units, marine and food industries, and particularly in the aerospace industry. Machinability of Ti-6Al-4V in wire electric discharge machining (WEDM) has been empirically investigated. WEDM performance tests were conducted on TiN coated Ti-6Al-4V alloy with physical vapor deposition (PVD) method, which is harder and has higher wear resistance. The performance of machinability of Ti-6Al-4V and Ti-6Al-4V/TiN materials was analyzed. The most important performance characteristics of WEDM cutting are surface roughness, machining gap, and cutting speed. The tests were conducted under cutting parameters including varying pulse durations (300, 500, 700 μs), tension (50, 100 V) and wire feed rate (5, 8 m/min). Based on tension, pulse duration, and wire feed rate of heat-treated uncoated samples when compared to untreated samples and coated samples, feed rates were found to be at the highest value.
