Solution:

A single-point cutting tool with a 12° rake angle is used to machine a steel workpiece. The depth of cut, i.e., the uncut thickness, is 0.81 mm. The chip thickness under orthogonal machining conditions is 1.8 mm. The shear angle is approximately:

22°

Solution:

Consider an operation carried out using Ultrasonic machining. The initial frequency and Material Removal Rate are 20 Hz and 10 mm³/min, respectively. If the frequency is changed to 25 Hz without affecting any other parameters, what will be the new Material Removal Rate value (in mm³/min)?

12.5

17.5

Solution:

A specimen is being ground on a surface grinder with a grinding wheel speed of 600 m/min and a work-piece speed of 25 mm/min. The grinding wheel diameter is 200 mm, and the grinding depth of cut is 0.025 mm. The transverse feed of the work-piece is 4.4 mm/pass, and the specific cutting energy is 2200 J/mm³. Assume the pitch of the grits at the periphery of the grinding wheel is 12 mm, and the factor for the negative rake angle of the abrasive grains is 5. What is the mean grinding power in the above operation?

0.504 kW

0.680 kW

0.432 kW

0.724 kW
