QUESTION 1 Describe three types of chip formation with a diagram. Assuming a positive rake angle, which chip form would probably be best for production purposes, the worst for production purposes, and be the worst for the machine tool over a. long period of time? Explain. QUESTION 2 Mild steel is being machined under the following conditions: Width of out 'w = 2.0mm, Rake angle a: = 10°, Cutting speed V = 200m/min, Uncut chip thickness to = 0.2mm, Coefﬁcient of friction u = 0.5, Shear strength of the material 1‘ = 400N/mm2. a) Determine the shear angle using Merchant’s theory. b) Determine the cutting and thrust force components. Mechanical Engineering 4283 Term Test 3, November 18, 2010 Manufacturing Engineering II Dr. Andy Simoneau QUESTION 3 3.) Describe two types of tool wear, include a drawing. b) What material and cutting conditions do you think would lead to each type of wear? 0) Setting n = 0.5 and C = 400, calculate the percentage increase in tool life when the cutting speed is reduced by 50%.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
