1. A small ball is attached to a wall by two identical springs as shown below. If the ball was released at a x = xo (small displacement from equilibrium position) (a) with 0 velocity, what is the oscillation frequency? (b) released at x = With a damping force F = -bv and a driving force F = F,sin (wt), the ball was xo with 0 velocity, what is x(t) in the steady state? (You do not need to solve %3| the equation from scratch. You can find the answer based on your notes.) In (b), if the ball was released at x = -xo with 0 velocity, what is the steady state (c) x(t)?

Please typing answer only IENG 302 - Manufacturing Processes: We are reducing the diameter of a 95.8 mm cylinder to 30.04 mm using 7 roughing passes and 3 finishing passes. The finishing operations use a depth of cut of 1.51 mm. The roughing operations are performed with a feed rate of 9.61 mm/s and the finishing operation is performed with a feed rate of 11.31 mm/s. a) What is the depth of cut for a roughing pass? b) What is the rate of material removal (mm^3/s) for the third roughing pass? c) What is the rate of material removal (mm^3/s) for the final finishing pass? d) What is the average rate of material removal (mm^3/s) for the roughing operations?

Consider a milling process, where a pocket with width (X) of 400mm, Length (Y) 300mm, and depth (z) of 15 mm. The cutting tool is a 12 mm diameter flat end mill with 4 cutting edges. For some reason, the tool can be radially immersed in the material at most 50% of the tool diameter. The spindle speed is selected as 2000 rpm, where the max allowable axial cutting depth is 2.5 mm. a) Calculate the number of total cutting steps, indicating which feed direction would you prefer x or y. It may be preferred to have feed rate can be along X direction Total # of cutting steps: If feed direction is along X, the total number of cutting steps is 294 b) Calculate the minimum achievable cycle time if the feed rate is 0.15 mm/rev/tooth. Approx cycle time: 98 minutes
