1. Define 5D in your own words. If it was defined as an operation that uses "trochoidal passes with a big and tightly controlled maximal radial engagement", what operation is being referred to? 2. Is multiple depth associated with vertical passes? When can you increase multiple depth? 3. How is Optimal Load calculated? 4. The XYZ table of a CNC machine has to be moved from point (1,-18,7) to point (6,1,- 16). Each axis can move at a velocity (IPM) of .02 ft/sec. Calculate travel time in X, Y and Z axes? Also, find the multiple depth if 9 layers are to be made on the Z axis? 5. Define SFM in your own words. 6. A mild steel stock is fed with a .475 inch Flat End Mill at the MIT Manufacturing lab. Calculate the RPM and the Chip Load/tooth? The mill has 3 teeth and the IPM is not to exceed 175 in/min.
