Q1_Tuming operation carried out on Aluminum shaft with specific energy of 0.7 N.m/mm. Cutting speed 5.6 m/s, feed 0.25 mm/rev and depth of cut 2 mm. the lathe has mechanical efficiency of 0.85. determine cutting power and gross power in watts. Q2_A ceramic cutting insert which has a Tylor equation exponent of (0.2) has been used in production line at cutting speed of 360 m/min, the tool failed after 155 min of machining. Calculate tool life if the cutting force Solve questions 1,2 and 3 a) Decreased 30% b) Increased 20%. Q3_ What is the chip-load required to remove 1350 mm^3 each minute in a milling process. The five-teethed cutter moves with cutting speed 80 m/min, and has a diameter 90 mm, the width of cut is 6 mm and depth of cut is 3 mm.
