Calculate the center-of-gravity, i.e., the optimal solution of the minisum location problem with squared Euclidean distances.
Set up the capture table and apply the Greedy heuristic to locate 3 facilities. Where should the facilities be located and what is the total capture?
Ignore the solution found in (b) and improve the solution in (a) by the vertex substitution method.
Write the APT geometry statements to define the hole positions of the part in Figure. Use the lower left corner of the part as the origin in the x-y axis system
Cutting speed = 100 m/min and feed = 0.06 mm/rev. Use the lower left corner of the part as the origin in the x-y axis system.
The part in Figure is to be drilled on a turret-type drill press. The part is 15.0 mm thick. There are three drill sizes to be used: 8 mm, 10 mm. and 12 mm.
The outline of the part in Figure is to be profile milled, using a 20-mm diameter end mill with two teeth. The part is 10 mm thick.
Cutting speed = 0.4 m/see, feed a 0.10 min/rev, and table travel speed between holes = 500 mm/min. Postprocessor call statement is MACHIN/DRILL.04.
Use the TURRET command to call the different drills required. Cutting speed = 0.4 m/sec, feed = 0.10 mm/rev
