[7 marks]Write the importance of machine time calculation.
[3 marks]Define Tool Approach and Tool Travel with the help of neat sketch.1
[4 marks]Amild steel bar 100 mm long and 38 mm in diameter was turned to mm dia. and was again turned to a diameter of 32 mm over a length of 40 mm as shown in Fig.1. The bar was machined at both ends to give a chamfer of 45° × 5 mm after facing. Calculate the machining time. Assume a cutting speed of 60 m/min and feed 0.4 mm/rev. The depth of cut is not to exceed 3 mm in any operation Figure 1.
[7 marks]Enlist different types of lathe operations.
[3 marks]Deduce an expression for machining time in the planning machine.
[4 marks]Find the time required to drill 4 holes in a cast iron flange each of 2 cm depth, if the hole diameter is 2 cm. Assume the cutting speed as 21.9 m/min. and feed as 0.02 cm/rev.
[7 marks]Highlight the importance of costing and estimating.
[3 marks]What is the difference between the operation sheet and the route sheet?
[4 marks]Discuss the production equipment and tool selection for the component shown in Figure 2. Consider undercut diameter is 12 mm. Figure 2.
