The recommendation value of cutting speed is 600 sfm for one inch diameter, 4 flutes carbide end mill. The recommendation value for the feed is 0.02 in/tooth. What's the spindle speed (rpm) and feed rate (in/min) should be?
D) = 12
1) = 2292 rpm
2292 = 183 in/min
Define (i) Speed (V), (ii) Feed (f), and (iii) Depth of cut (t) on a machine tool.
1) Speed (V): (Fig. 21-1a)
-- the velocity of cutting tool relative to the workpiece.
(2) Feed (f): (Fig. 21-1b,c)
-- amount of material removed per revolution or per pass of the tool over the workpiece.
(3) Depth of Cut (t):
-- the depth of material removed in each cycle.
List three types of materials of cutting tools.
Tool Steel, High Speed Steel, Cast Cobalt Alloy, Carbide
Under the same working conditions, which of the following tools will have longer life?
Cast cobalt alloy
Which of followings basic manufacturing processes uses lathe, mill, and drill?
in the Oxyacetylene welding, do you open the acetylene valve first or the oxygen valve to light it up?
Open acetylene first
Which valve needs to be closed first when finished welding?
Close acetylene first
What is Oxygen to Acetylene ratio for most of the welding?
1.1:1 or 1.15:1
Which type of the arc welding uses separate filler metal wire?
List four types of arc welding.
SMAW, MIG, TIG, Plasma arc welding
Name the welding that could butt joint between pipes and forced them together
Pressure Gas Welding
Explain the differences between MIG and TIG.
MIG uses consumable electrode
TIG uses non consumable electrode (need external filer material)
List three other types of welding other than OFW and arc welding
Resistant welding (resistant spot and resistant seam welding) Solid-state welding (forge welding, cold welding, ultrasonic welding) Unique process (laser beam welding, electron beam welding)
List four types of Nondestructive Tests.
Visual inspection Liquid penetrant Magnetic Particle Ultrasonic inspection Radiography Eddy-current inspection
What kind of tests uses sound wave to detect the defect of material?
What kind of nondestructive tests uses X-Ray?
