Whаt cоmplicаtiоn will the nurse mоnitor for in а patient with polycystic ovarian syndrome?
(6 pts) 1 а. Explаin the effects оf lоw аnd large die angle оn ram force in extrusion. (4 pts) 1 b. What is the process shown in the figure? What in general is this process used for? (5 pts) 1 c. Write down the equation for drawing with friction. From the equation, show the relationship of the die angle and the drawing force. What would happen if the angle is too big or too small? Assume that Af = 0.5 A0. Mention if you made any other assumptions. (5 pts) 1 d. Explain the roll/function of different regions of the drawing die. (6 pts) 2 a. Explain the terms “Aspect ratio” and “Shape factor” used to describe metal podwers. (10 pts) 2 b. Describe compaction of metal powders by isostatic pressing. Explain the two types of isostatic pressing and discuss their advantages and limitations. (4 pts) 2 c. Why Sintering is performed in Powder metallurgy process? (6 pts) 3 a. Mention at least two reasons to justify the need for nontraditional machining (NTM) processes. Explain any one limitation of a NTM process. (6 pts) 3 b. A “UC” logo is to be printed using ECM on a plate of pure copper plate (valence = 1). The tool is made into a UC shape. The depth of the logo is asked to be 4 mm. At current 100A, the logo is printed in 70 seconds. How long would it take if the logo is asked to be 2 mm but fabricated at 50 A? Explain your answer. (8 pts) 3 c. If you need to develop a hybrid machining process by combining a traditional and a nontraditional process, what would be your choice? Why?. (10 pts) 4 a. Rewrite the following part program in incremental mode. Assume starting point is 30 below point P1 Part program in absolute mode ----- N080 G01 Y130 F200 Straight line from starting point to P2 N090 G01 X100 Straight line from P2 to P3 N100 G01 Y105 F150 Straight line from P3 to P4 N110 G02 X70 Y105 R15 Radial arc, clockwise, with 15 radius N120 G01 Y130 F200 Straight line from P5 to P6 N130 G01 X10 Straight line from P6 to P7 N140 G01 Y20 Straight line from P7 to P8 N150 G03 X20 Y10 R10 F150 Radial arc, counterclockwise with 10 radius N160 G01 X190 F200 Straight line from P9 to P1 N170 G01 Z35 F200 Retraction from workpiece N180 G00 X300 Y300 Rapid traverse away from workpiece ----- Incremental mode: ----- N080 G01 Y 150 F200 Straight line from starting point to P2 N090 G01 X N100 G01 Y F150 N110 G02 X Y R15 N120 G01 Y F200 N130 G01 X N140 G01 Y N150 G03 X Y R10 F150 N160 G01 X F200 N170 G01 Z35 F200 Retraction from workpiece N180 G00 X100 Y-100 Rapid traverse away from workpiece (10 pts) 4 b. What is an open loop and closed loop control system? Explain the advantage and limitation of both systems. (10 pts) 5 a. Explain any one application for which you would suggest additive manufacturing over traditional methods. Justify your suggestion. (10 pts) 5b. A prototype of a wedge shown in the adjacent figure is to be fabricated by stereolithography process. The layer thickness = 0.20 mm. The diameter of the laser beam (“spot size”) = 0.15 mm, and the beam is moved across the surface of the photopolymer at a velocity of 300 mm/s. Compute the minimum possible time required to build the part, if 5 sec are lost each layer to lower the height of the platform that holds the part. Neglect the time for postcuring. All dimensions are in mm. If you have any difficulties in uploading your exam file in Canvas, email it to jamunktr@mail.uc.edu before 12. 05 PM
