List them in their order of relative hardness-i.e. from hard, harder to hardest to extremely hard? (CO3, PO2, C4) b) Describe the advantages of the Computer Numerical Controlled (CNC) milling machine as compared to the conventional or manually operated one? (CO3, PO2, C4) c) What are the advantages and disadvantages of welding compared to other types of assembly operations? (CO3, PO2, C4)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 referc) 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?2 Answer the following questions by circling True or False. 1. Open structures are used for precision forms and profile grinding. 2. In centre-less grinding operation, it is possible to grind cylindrical workpiece without actually fixing the workpiece using centres or a chuck. ( ) 3. Since all the machining parameters are built into the broach, very little skill is required from the operator. ( ) 4. The machined surface should be used as the clamping surface as it can improve the clamping stability. 5. During the measurement, a comparator is able to give the deviation of the dimension from the set dimension.
