QUESTION 1 A NC drill press is to perform a series of through-hole drilling operations on a 1.75 in thick aluminum plate that is a component in a heat exchanger. Each hole is 3/4 in diameter. There are 100 holes in all, arranged in a 10 by 10 matrix pattern, and the distance between adjacent hole centers (along the square) = 15 in. The cutting speed = 300 ft/min, the penetration feed (z-direction) = 0.015 in/rev, and the traverse rate...

.Suppose you want to drill a 2-in. thick plate of cast steel (0.4%C), 4-in. diameter hole. An indexable HSS insert drill has been selected. Consider the table below, select the appropriate cutting speed, feed rate. Calculate the spindle speed (rpm), the feed rate (in/min), the MRR, and cutting time. Assume the cutting process will be performed in3 steps using 3 drills sizes in sequence 1”, then 2”, then 4”. Calculate the cutting total cutting time, considering a proper allowance each...
