Concept explainers

Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

What wheel shapes are commonly used for surface and cylindrical grinding?
a) Explain with a neat diagram about Honing process (Minimum one and half page)b) What is grit and grade in a grinding wheel? and refer
c) It is planned to carry out the grinding operation using a grinding wheel of diameter 15 cm and width 2 cm, and using successive depths of cut of 0.02 mm, with two final cuts of 0.01 mm each. Wheel speed is 1450 m/min, work speed is 0.25 m/s and the cross feed is 0.4 mm. The number of active grits per area of the wheel surface is 0.75 grits/mm? with a grain aspect ratio of 20. i) Determine the Material Removal Rates for both depths of cut. ii) If the cycle time for one forward/return stroke of the work during grinding is 5 sec., estimate the total time taken to complete the job. ii) Considering a constant of proportionality K2 of 40,000, determine the maximum surface temperature of the work. iv) What recommendations would you give to reduce any surface damage owing to high work temperatures?
Answer the following questions by circling True or False. 1. Creep feed grinding is an operation used for large material as compared to the conventional grinding operation, and it uses hard grinding wheels and small depths of cut. 2. For sawing softer materials, fine pitch blades are used since they produce long chips, while coarse pitch blades are used for sawing harder materials. 3. The machined surface with high finish should be used as the clamping surface to guarantee machining accuracy 4. Since the fixture elements are reusable, the overall cost for modular fixturing is less. 5. Using the slip gauges can obtain the exact value of the part dimensions. ( ) ()
