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=lmm 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/(cm/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

Machining Processes and Machine Tools

Machining is represented as the process in which an excessive amount of substance is eliminated from the particular element in the form of pieces. In machining, cutting tools such as rotary tools, lathe, drill press, grinder, chop saw, welders, and many more are applied to get the desired shape. As compared to other manufacturing processes, machining is precise and versatile.
