Machinability ..Machinability= (v t /v s ) x 100%v s – specific CS for standard materialv t – specific CS for test materialMachinability is affected by• Condition of machine/tool• Cutting conditions• Type of operation• work material© rkm2003
© rkm2003EXAMPLE 4.1While machining carbon steel by a tungstenbased steel tool, tool life of 50 minuteswas observed when machined with acutting speed of 100 m/min. Determine(a) General Taylor’s tool life equation and(b) tool life for a cutting speed of80 m/min. Assume n = 0.09.Work material: carbon steelTool material: tungsten based tool steel
