Question

rtant: Be precise; use sketches, formulae, and name all mathematical symbols you use. cutting force in turning is given by F-KA where A is the cross section of cut and K is the ultimate shear strength of the work material. Calculate: (a) material removal rate (MRR) and (b) the total power required by the machine for cylindrical surface turning of solid rods of 50 mm diameter with a tool feed rate of 0.05 mm/work rotation, depth of cut of 3 mm and a spindle speed of 140 rpm. Given K # 1200 N/mm2. Assume 40% of the total power required by the machine is lost due to friction, wear, redundant work and the kinematic transmission of the lathe. (10 pts) . Page 3 3. Write very briefly how you can accommodate in this course syllabus of INME 4055 Manufacturing Processes) the following professional issues of engineering: (use sentences, bullets, etc. You can write in Spanish or English but don't mix them. If you write in Spanish use proper orthographic accents). You can use case studies, personal experience and/or theoretical constructs in order to establish and put forward your point of argument. (5 points) (a) Engineering Ethics: (b) Global Awareness (c) Lifelong Learning: Conclusions:

Answer 1

For 2nd question, some more data required about the depth of cut and feed.

For 3rd question, it is general question. They are expecting the answer from your point of view.
