In a process of metal casting, the final product’s volume is 1275 cm3. Casting waste, scrap allowance, and shrinkage allowance are 8%, 12%, and 3.5%, respectively. The metal supplier pays $0.5/kg, irrespective of the type of metal. Determine the material cost, if the following metals are used for casting: a. Aluminum (ρ = 2.7 g/cm3 ; cost = $1.85/kg) b. Grey Iron (ρ = 6.8 g/cm3; cost = $1.38/kg) Calculate the overall efficiency of the economic conversion of raw materials.

In a casting machining company, it takes an operator 30 seconds to load ,15 seconds to unload each machining center. There are several same centers, all working on the same type of part, and the duration of the automatic operation is 1 minute. The travel time between machines is 15 seconds. Given that the cost per hour of the operator $8 and the cost per hour of the machine is $10, using the man-machine diagram, determine the value of the highest production rate for the system
Pouring Calculations A mold sprue is 25 cm long, and the cross-sectional area at its base is 3.0 cm2. The sprue feeds a horizontal runner leading into a mold cavity whose volume is 1700 cm3. 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. (The acceleration of gravity g = 981 cm/s2) use cm keep all unit in cm

We have obtained a contract to construct metal boxes (square bottom, rectangular sides, no top)for storing sand. Each box is to contain a specified volume, and all edges are to be welded. Eachbox will require the following information: A volume (V, in units of cubic inches), the length ofone side of the bottom (L, in units of inches), the box height (H, in units of inches), and thematerial cost (M, in units of dollars per square inch). To determine the total cost to manufacture abox, we must include not only the cost of the material, but also the cost of welding all the edges.Welding costs depend on the number of linear inches that are welded (W, in units of dollars perinch). The client does not care what the box looks like, but it should be constructed at theminimum cost possible.(a) Construct a worksheet that will depict the cost of the material for one box, the welding costfor one box, and the total cost for the box, First, create at the top of your worksheet a section toallow the…
