11) An internal bore is ground to 100 mm, removing 0.3 mm stock. To accomplish this, a grinding wheel 80% of the finished size is used. The wheel is dressed every 15 cycles because it is observed that the radial wheel wear is 0.05 mm on average. Assume wheel and part widths are equal. a What dressing depth would you recommend and why? b. Calculate the G-ratio of this operation.

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.

Why is it necessary to grind HSS lathe tool bits? What are the objectives in Grinding HSS Lathe Toolbits? Elaborate your answer and please make it typewritten.
In a surface grinding operation performed on a 6150 steel workpart (annealed, approximately 200 BHN), the designation on the grinding wheel is C-24-D-5-V. Wheel diameter =178 mm and its width= 25 mm. Rotational speed = 3000 rev/min. Infeed = 0.05 mm per pass, crossfeed = 12.5 mm, and workpiece speed = 6 m/min. This operation has been a source of trouble right from the beginning. The surface finish is not as good as the 0.4 µm specified on the part print, and there are signs of metallurgical damage on the surface. In addition, the wheel seems to become clogged almost as soon as the operation begins. In short, nearly everything that can go wrong with the job has gone wrong. (a) Determine the rate of metal removal when the wheel is engaged in the work. (b) If the number of active grits per cm? = 30, determine the average chip length and the number of chips formed per time.

Q1. Calculate the time required to machine a workpiece 170 mm long, 60 mm diameter to 165 mm long 50 mm diameter. The workpiece rotates at 440 rpm, feed is 0.3 mm/rev and maximum depth of cut is 2 mm. Assume total approach and overtravel distance as 5 mm for turning operation. Answer Q2. A gray cast iron surface 280 wide and 540mm long may be machined either on a vertical milling machine, using a 100mm - diameter face mill having eight inserted HSS teeth, or on a horizontal milling machine using an HSS slab mill with eight teeth on a 200-mm. diameter. Which machine has the faster cutting time? The values of feed per tooth and cutting speed for both processes are 0.4mm/tooth and 80m/min, respectively. The depth of cut = 3.0 mm and assume A and O equal to 5. Answer
In a production turning operation, the workpart is 60 mm in diameter and 500 mm long. A feed of 0.75 mm/rev is used in the operation. If cutting speed-9 m/s, the tool must be changed every 4 workparts; But if cutting speed=5 m/s, the tool can be used to produce 50 pieces between tool changes.
