Questions (page 2)
Q2. Q.1B. Following data is obtained In an orthogonal cutting operation on a material with the shear yield strength of 250 N/mm2, the Rake angle of the tool = 15 deg; Uncut chip thickness = 0.25 mm; Width of chip = 2 mm; Chip thickness ratio = 0.46 Friction angle = 40 deg. Determine the shear angle, the cutting force component and resultant force on the tool.
Q3. Q.2. Explain with a sketch, the 3-2-1 principle of location in the context of jigs and fixtures.
Q4.
Q.3. Consider an NC machine center processing raw parts one at a time in M/M/1 queue (Poisson process arrival, exponentially distributed service time and a single server). Let arrival rate be 8 parts/hr and service rates be 10 parts/hr. Compute the performance measures
(i) Machine utilization;
(ii) Mean number of customers in system;
(iii) Mean number of customers in queue;
(iv) Mean waiting time in system;
(v) Mean waiting time in queue
Q5. Q.4. Write a note on Patterns and Pattern Materials in expendable mould casting.
Q6. Q.5. A cloth vendor wants to determine the optimal order size and total inventory cost for a brand of cloth. This brand of cloth has an estimated annual demand of 10000 yards. The annual carrying cost is 0.75 per yard, and an ordering cost of 150. The store would also like to know the number of orders that will be made annually and the time between orders (order cycle) given that the store is open for 311 days in a year.
