Concept explainers
The chalk tray on a classroom chalkboard has very few performance requirements. As a result, it can be made from a wide spectrum of materials. Wood, aluminum, and even plastic have been used in this application. Discuss the performance and durability requirements and the pros and cons of the three materials. Chalk trays have a continuous cross section, but the processes used to produce such a configuration may vary with material. Discuss how a chalk tray might be mass�produced from each of the three material classifications. Might this be a candidate for some form of wood by�product similar to particle board? Because the product demands are low, might some form of recycled material be considered?

Degarmo's Materials And Processes In Manufacturing
- Suppose your company has just found $100,000 worth of outdated inventory in an old warehouse (this is the original manufacturing cost). Your boss asks you to consider two options: (1) re-engineer the outdated parts at a cost of $30,000, and ideally resell them for $60,000, or (2) scrap them for $15,000 cash (which is certain) in a second-hand market. What advice would you give your boss? Explain in your own words and give the data that supports your answer.arrow_forwardSelect an appropriate manufacturing process, where dimensional accuracy and precision is not important for most of the part features. However, certain features such as tapped holes and bore hole require precision. Assume the material is delrin.arrow_forwardYou have been using pens and mechanical pencils for many years now. Investigate the design of at least five different pens and mechanical pencils. Discuss what you think are important design parameters. Discuss the advantage and disadvantage associated with each design. Write a brief report explaining your findings.arrow_forward
- answer fastarrow_forwardPlease give answers to both of these parts, thanks (a) Manufacturing is “ the transformation of materials into items of greater value by means of one or more processing and/or assembly operations”. Elaborate on this statement (b) It is not possible to conduct a rolling process without friction. Explain this statement.arrow_forward• In a sheet metal forming press the shape to be formed is hemispherical cup of radius 15 cm in 2mm thick mild steel sheet. The force required to deform sheet is 8 kN. The forming hammer should approach job from a distance of 30 cm. The production rate required is 240 components/hr. Calculate and suggest the following specifications of the various hydraulic components used: a) Hydraulic cylinder (bore & length) b) Pump pressure and flow rate c) Electric motor HP considering 75% pump efficiency d) Reservoir size e) Size of pump inlet and discharge tubingarrow_forward
- Imagine you are presenting a product or appliance you know well to a potential client. Describe the categories of material used to make the different parts.arrow_forwardPlease don't provide handwritten solution .....arrow_forwardSolid modelling is an alternative to traditional three-dimensional modelling, which consists of just stringing together lines, that allows designers to give their products a look and an organic feeling of movement. Explain?arrow_forward
- " This is sensible, since many sorts of creation include kitting the entirety of the materials". Please explain the term "kitting" as it is used here.arrow_forwardDiscuss the process of converting raw materials into finished product in a brief manner.arrow_forward1. In the manufacture of automotive-body panels from carbon-steel sheet, stretcher strains (Lueders bands) are observed, which detrimentally affect surface finish. How can stretcher strains be eliminated? Explain with appropriate sketches. Also discuss how wrinkles in a deep drawing operation can be eliminated.arrow_forward
