Casting problem A certain mold has a sprue whose length is 20 cm and the cross-sectional area at the base of the sprue is 2.5 cm?. The sprue feeds a horizontal runner leading into a mold cavity whose volume is 1560 cm'. Determine: (a) velocity of the molten metal at the base of the sprue, (b) volume rate of flow, and (c) time to fill the mold (in second).

Consider the red aluminum tool holder shown in Figure 4. Your job shop has been contracted to make 5 pieces this year, with possibility of making 5 more each year in the future. Consider the process options below, which option is the best? a) using sand mold, cast the holder without hole using a mill, cut all planar surfaces (smooth surfaces) using a mill or drill press, cut the hole anodizing the holder to red color b) using injection molding anodizing the holder to red color c) using die casting, cast the holder anodizing the holder to red color d) using a hacksaw, cut a piece of 3"X3" bar stock to length using a mill, cut all planar surfaces using a mill or drill press, cut the hole anodizing the holder to red color

1. A milling operation is to be performed on a ductile cast iron shaft to make slots for assembly. The operation will be done at high speeds for good surface finish. For each of the following tool materials, indicate whether it is a reasonable candidate to use in the operation with a detailed description of why or why not including required alloying element/grade/group etc. where applicable: (i) plain carbon steel, (ii) high-speed steel, (iii) cemented carbide, (iv) ceramic, and (v) Sintered polycrystalline diamond. After selection of material/materials discuss about (i) recommended angles and tool signature (ii) how to held cutting edge, and type of cutting fluids With reasons for each recommended material. 2. Make a figure and explain how shear plane angle effect the power requirements in the machining. How can you reduce the power requirements during machining in orthogonal cutting?
