MILLWRIGHT FIRST YEAR THEORY || WITH CORRECT
SOLUTIONS.
is a morse taper self holding and what is the taper per foot correct answers yes a morse taper
is self holding. the taper per foot is 5/8th
is a machine taper self holding and what is the taper per foot correct answers it is not self
holding. the taper per foot is 3 1\2
what are the three ways to produce a taper on a lathe correct answers tailstock offset, taper
attachment and combination rest
cutting speed refers to what correct answers the peripheral speed
what should the rpm and feed rate of a reamer be compared to a drill correct answers rpm
should be slower and feed rate higher
turning is usually done with what correct answers a right hand tool
what is the imperial equation to find rpm correct answers cutting speed times four divided by
diameter
what is the abbreviation used to express the feed rate on a drill press correct answers ipr/
inches per revolution
as a general rule the maximum depth of cut for an end mill is equal to what correct answers
half the diameter of the end mill
what is a clearance fit correct answers the largest tolerance shaft will fit in the smallest
tolerance hole
what is an interference fit correct answers the smallest tolerance shaft does not fit in the
largest tolerance hole. Meaning the use of force and or heating the hole and freezing the shaft
may be required
what is a transition fit correct answers the mating parts tolerance allow for either a clearance
fit or an interference fit depending on the size of the shaft and hole within tolerance
what are the parts of a lathe correct answers headstock, tailstock, the bed, the ways, the
carriage, quick change gear box, back gears, the lead screws feed rod and rack
what are the parts of the carriage correct answers apron, saddle, cross slide and compound
rest
define allowance correct answers the difference between basic dimensions of mating parts
define tolerance correct answers the total amount a part may vary
what fit system is most common correct answers hole basis system
