MMET 380 EXAM 2 QUESTIONS AND
ANSWERS ALL CORRECT
Water droplets roll freely on a coated material (P) because surface tension is
water > P
water > air
P > air
P > water - Answer- Water > P
In this statement 'N10 G90 G20 F5 S50' the tool feed rate is
50 in/min
5 in/min
50 mm/min
5 mm/min - Answer- 5 in/min
In a highly automated system, the average manning level should be:
+1.0
+1.25
-1.25
None of the above - Answer- None of the above
In machining, the cutting speed for minimum cost when time is critical depends on:
Set up time
Tooling cost
Overhead cost
All of the above - Answer- Set up time
Group cell arrangement allows
Standardized tooling setup
Maximum material handling
Optimal cutting speed and tool life
All of the above - Answer- Standardized tooling setup
Given specific materials for tool and workpiece, tool life in face milling depends mainly
on:
Milling speed
Milling feed rate
Radial depth of cut
Milling feed - Answer- Milling speed
