I need the answer at 20 minute 1- Explain why a casting may have to be subjected to various heat treatments.2- Describe the drawbacks to having a riser that is (a) too large and (b) too small.3- Explain the effects of mold materials on fluid flow and heat transfer in castingoperations.4- Explain why continuous chips are not necessarily desirable.5- List the factors that contribute to poor surface finish in cutting.6- Tool life can be almost infinite at low cutting speeds. Would you thenrecommend that all machining be done at low speeds? Explain7- The cutting force increases with the depth of cut and decreasing rake angle.Explain why.8- Explain the segregation in casting of alloys.

Given questions are related to manufacturing engineering and material science. Why a casting may…

The channel shape cross-section and the rectangular cross-section shown in the Figure Q4 are made of materials with elastic-perfectly plastic behaviour. The yield stress of the material used for the channel shape cross-section is σy = 449 MPa, whereas that used for the rectangular cross- section is 0.7%y. Compute the thickness of the web, t, of the channel shape section if the two cross sections have identical plastic bending moment about the z-axis. In Figure 4, h= 96 mm, b=43 mm, a=12 mm, H=96 mm, d= 43 mm N b h a Z a | d H
A flow shop consists of 3-Machines on which 4-Jobs have to be scheduled in a fixed sequence. The process times of the four jobs are given in the table below. In this table Pij, P2j and p3j indicate the process time of the jth job on Machine-1, Machine-2 and Machine-3 respectively. Work out a near-optimum schedule of processing the jobs for heuristically minimizing the Makespan using Palmer's Method. Job (j) J1 J2 J3 J4 4 8 4 2 2i P3j 4 Calculate the following: (i) The Minimum and the Maximum Processing Times on the 3-machine and hence conclude whether the machines satisfy the Johnson's criteria for 3- machines. (ii) (ii) Calculate the Directed Graph and Gant Chart; Hence calculate the value of Makespan, Cmax. (iv) Calculate the slope-index and hence decide the heuristic schedule; SO53 5M56
