Investigation of machinability characteristics on EN47 steel for cutting force and tool wear using optimization technique

摘要: In this experimental work dry turning process carried out on EN47 spring steel with coated tungsten carbide tool insert 0.8 mm nose radius are optimized by using statistical technique. Experiments were conducted at three different cutting speeds (625, 796 and 1250 rpm) feed rates (0.046, 0.062 0.093 mm/rev) depth of cuts (0.2, 0.3 0.4 mm). based full factorial design (FFD) 33 factors levels. Analysis variance is used to identify significant factor for each output response. The result reveals that rate the most influencing force followed cut speed having less significance. Optimum machining condition obtained from Tool wear measurements performed optimum Vc = rpm, ap 0.2 mm, f 0.046 mm/rev. minimum observed as 0.086 5 min machining. was done confocal microscope it increases increasing time.
