A 200 mm long magnesium alloy bar, 63 mm in diameter is turned on a lathe using a high  speed steel cutter travelling at 180 mm/min. The spindle rotates at 450 rpm and lathe is  equipped with a 10 kW motor, operating at a mechanical efficiency of 92%. The final  diameter of the magnesium alloy bar is 59,5 mm. Indicate with a sketch the recommend size and location of the following tool angles: back  rake, side rake, end relief, side relief and side and end cutting edge. Calculate the cutting time for the machining process. Calculate the required cutting force.

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.
