Challenge Problems
Push your limits with advanced challenges
Calculate the MRR when the cutting speed is 100 mm/min, feed rate is 0.25 mm/rev, and depth of cut is 2mm. Explain how changes to these parameters would affect MRR.
💡 Hint: Focus on how multiplication affects the output.
Discuss how surface conditions affect the performance of machined parts in critical industries and suggest methods to improve surface integrity.
