2026 MILLWRIGHT LEVEL 1 EXAMS SCRIPT
QUESTIONS AND ANSWERS SURE A+
✔✔The ________ is the amount of metal removed by each tooth per revolution -
✔✔Chip load
✔✔Determine the feed rate if a milling machine spindle has a speed of 200rpm and the
cutter has 6 cutting edges with a chip load of 0.003" - ✔✔Feed= Chip Load x Spindle
Speed x # of Teeth
0.003 x 200 x 6 = 3.6
✔✔Why would you use parallels under a workpiece when plunge cutting a through-
hole? - ✔✔to prevent cutting in the table
✔✔Why should you clean an lightly oil milling machine tables? - ✔✔To prevent rusting
which causes loss of accuracy
✔✔Why should you store end mills separate from one another? - ✔✔Cutting edges
could chip and wear
✔✔What is climb milling? - ✔✔Feeds into the rotation of the cutter and bites into the
material pushing it down and into the table
✔✔What is conventional milling? - ✔✔Feeds against the rotation of the cutter and tends
to lift the workpiece
✔✔What is the level of accuracy for a plate protractor? - ✔✔Within 1 degree
✔✔What is the level of accuracy for a universal bevel protractor? - ✔✔5 minutes of a
degree
✔✔How many minutes are in a degree? - ✔✔60 minutes
, ✔✔What is a vernier scale? - ✔✔Compares 2 sets of graduations to magnify the
accuracy of the measuerment
✔✔What does a dial caliper use to move its pointer around the face of a dial - ✔✔Rack
and pinion
✔✔What is the construction of a micrometer? - ✔✔1. Anvil
2. Spindle
3. Sleeve
4. Thimble
5. Ratchet
6. Lock nut
7. Frame
✔✔What method provides most accurate measurement when it comes to a
micrometer? - ✔✔Ratchet method because it releases at the same pressure every time
✔✔Regular micrometer scale level of accuracy is: - ✔✔0.001"
✔✔Vernier micrometer scale level of accuracy is: - ✔✔0.0001"
✔✔What is an Intrimik? - ✔✔Has 3 contact points rather than 2 making it self centering
✔✔What is different about the scale of a depth micrometer from a regular micrometer? -
✔✔The distance measured is covered by the thimble
✔✔What kind of tool is a taper gauge? - ✔✔Direct reading tool
✔✔What is a taper gauge used for ? - ✔✔Determining the width of a slot or diameter of
a hole and amount of angular misalignment
✔✔The difference between a screw and a bolt is the: - ✔✔Application
✔✔Why are thread forming screws used? - ✔✔Convenient in sheet metal assemblies
✔✔The major diameter of a thread is shown on a drawing as 0.748 +/- 0.002. What is
the tolerance on the major diameter? - ✔✔0.004
✔✔The pitch diameter of a thread is measured exactly halfway between the major and
minor diameters - ✔✔False. Its APPROXIMATELY halfway between the major and
minor diameter
