Seems incorrect setup, can you resolve?

In Orthogonal Cutting Model, why chip thickness after cut is greater than chip thickness before cut?

The curing process involves the following parameters except:   Question 8 options: a. Time b. Pressure c, Size d. Temprature

04 05 a Explain the reasons for the following: 1- The pure aluminum and the copper are generally rated as easy to machine 2- In ultrasonic machining, the stress produced by the impact of abrasive particles on the workpiece surface is high. 3- In rolling process, the coefficient of friction must be sufficient. 4- Difference in solidification between casting and welding processes. 5- Why is it desirable to use energy sources for welding that have high heat densities? 6- Why there might be a change in the density of a forged product as compared to that of the cast blank. D. A cylindrical workpart with D=2.5 in and h=2.5 in is upset forged in an open die to a height = 1.5 in. Coefficient of friction at the die -work interface = 0.10 The work material has a flow curve defined by: K= 40,000 lb/in' and n-0.15. Determine the instantaneous force in the operation (a) just as the yield point is reached (yield at strain = 0.002), (b) at height = 2.3 in. (c) h= 1.9 in, and (d) h = 1.5 in. a List…
