c) It is planned to carry out the grinding operation using a grinding wheel of diameter 15 cm and width 2 cm, and using successive depths of cut of 0.02 mm, with two final cuts of 0.01 mm each. Wheel speed is 1450 m/min, work speed is 0.25 m/s and the cross feed is 0.4 mm. The number of active grits per area of the wheel surface is 0.75 grits/mm? with a grain aspect ratio of 20. i) Determine the Material Removal Rates for both depths of cut.

Question
![c) It is planned to carry out the grinding operation using a grinding wheel of diameter
15 cm and width 2 cm, and using successive depths of cut of 0.02 mm, with two final
cuts of 0.01 mm each. Wheel speed is 1450 m/min, work speed is 0.25 m/s and the
cross feed is 0.4 mm. The number of active grits per area of the wheel surface is 0.75
grits/mm? with a grain aspect ratio of 20.
i)
Determine the Material Removal Rates for both depths of cut.
ii)
If the cycle time for one forward/return stroke of the work during grinding is 5
sec., estimate the total time taken to complete the job.
ii)
Considering a constant of proportionality K2 of 40,000, determine the maximum
surface temperature of the work.
iv)
What recommendations would you give to reduce any surface damage owing to
high work temperatures?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F144699d2-4930-4edd-b9a8-f41f8125a2e6%2Ff00048ba-c30f-4863-908b-1dd000135abe%2F65e6uko_processed.png&w=3840&q=75)
