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

Knurling is performed on a lathe, but it is a metal forming operation rather than a metal removal operation. 3. Friction between tool and chip tends to cause portions of tool material to adhere to the rake face of the tool near the cutting edge. This formation called a built-up edge. 4. Metal forming applies stresses that exceed the ultimate strength of the metal. 5. The plastic region of the stress-strain curve for a metal characterized by a proportional stress and strain. 6. if stress value were mesured during a tensile test, the higher value and important in manufacturing processes is the engineering stress. 7. Drawing is a compression proces in which the work metal is forced to flow through a die opening, thereby taking the shape of the opening as its own cross-section. 8.
