DONT COPY FROM PREVIOUS ANSWER IT IS WRONG I NEED CORRECT ANSWERSTEP BY STEP ELSE I WILL GIVE 10 DOWNVOTES MINIMUM IF U DONT KNOWNLEAVE IT BUT DI IF U KNOWN 100% RIGHTAn aluminum hollow shaft 200 mm outside diameter, 100 mm insidediameter and 500 mm length from lathe chuck is to be face turned atend. Its end face is finished at rotational speed of 400 rpm usingfeed rate of 0.25 mm/rev. The side cutting edge angle or lead angleof the tool is 30°. How much cutting time and maximum power isneeded to finish the facing operation with 4 mm depth of cut. Whatis likely to be a perpendicularity error in this operation?Specific cutting energy = 0.025 WI mm3/min and E = 50 kN/mm².
