The casting process cycle time is limited by the time it takes for the thickest part of the cast to solidify. The thickest part of the engine block is approximately 3 cm and takes approximately 30 minutes to solidify. Calculate the maximum thickness of a feature allowable to achieve a solidification time of 10 minutes.

A solid hexagonal shaped casting of thickness 3 cm and each side as 8 cm is being casted in a sand mold. The distance from top of the pouring cup to the sprue bottom is 20 cm, which is along the parting line. The diameter of the circular cross section at the base of sprue is 1.5 cm. The part is fully buried in drag side of the mold and top surface...
Question: During a sand casting process, the constant C in Chvorinov’s rule is 3 s/mm2. The process is used to produce a hollow cylindrical casting with an OD (outside diameter) of 75 mm, ID (inside diameter) of 50 mm, and a height of 125 mm. The mold contacts the cylinder on both the OD and the ID surfaces. a) Estimate the time for the casting to fully solidify. b) Write the equation used to calculate Chvorinov’s constant C. Based on...

Cycle Time, Velocity, Product Costing Mulhall, Inc., has a JIT system in place. Each manufacturing cell is dedicated to the production of a single product or major subassembly. One cell, dedicated to the production of mopeds, has four operations: machining, finishing, assembly, and qualifying (testing). The machining process is automated, using computers. In this process, the model’s frame and engine are constructed. In finishing, the frame is sandblasted, buffed, and painted. In assembly, the frame and engine are assembled. Finally,...
1. The process is performed by several resources. 2. Resources are shared across assembly lines (i.e., workers must multitask and perform multiple activities for every flow unit.) 3. The resource that limits hourly production is not the same resource that limits the process lead-time. From 2002 to 2009, Honda’s 1800cc cruiser-style motorcycle, the VTX1800, was assembled in Marysville, Ohio from four major subassemblies. The following is a simplified explanation of the assembly process. All resources are indicated in bold. •...
1 . Product A has a unit profit of $40 and takes 10 minutes on the bottleneck; Product B has unit profit of $60 and takes 30 minutes on the bottleneck. Non-bottleneck operations have infinite capacity because capacity can be added at no cost. The bottleneck has a capacity of 24 hours in a day. Should I maximize feasible production of: a. Product A b. Product B 2In terms of setting up a safety program, Heinrich’s Safety Triangle states the...

of the question below
In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 494 mL. The reserve and residual volumes of air that remain in the lungs occupy about 1980 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air Vt) in the lungs as a function of time. 01050- 34)...
