A number of through holes with 10-mm-diameter have been drilled through 30-mm thick cast iron plate. At a cutting speed of 25 m/min, the high-speed steel drill tool lasted for 44 holes. But, when the cutting speed increased to 35 m/min, the drill tool lasted for only five holes. The feed used in the both cases is 0.08 mm/rev. Determine the values of n and Cin the Taylor tool life equation for the data, where cutting speed v is expressed in m/min, and tool life T is expressed in min.

We need to obtain the following part by OD operation in turning, starting from a 100mm diameter cylinder. The maximum allowable depth of cut is 3mm. It is required to make a finishing pass with d=1mm and a feed of 0.3mm/revolution. 150 mm 150 mm The machine has a total power of 10hp and 85% efficiency. The material has a specific energy 500 based on of 25 W/(cm³/min). It is recommended to make the operation at a constant rpm = calculations made for an average diameter. Determine the minimum required time to finish the part. Hint: calculate the maximum material removal rate then the cutting speed for each pass, then the feed rate for each pass and finally the time of cutting. 80 mm 100 mm
