When designing patterns for casting, patternmakers use special rulers that automatically incorporate solid shrinkage allowances into their designs. For example, a 12-in. patternmaker’s ruler is longer than 1 foot. How long should a patternmaker’s ruler be for making patterns for (a) aluminum castings and (b) high-manganese steel?
(1) In sand casting, the volumetric size of the pattern is: (a) bigger than, (b) the same as, or (c)
smaller than the cast part
(2) Machining processes include which of the following (two correct answers): (a) casting, (b)
drilling, (c) extrusion, (d) forging, (e) shaping, (f), and painting?
(3) Aluminum sections used for making metal doors and windows are made by which process: (a)
Rolling, (b) welding, (c) extrusion, (d) turning.
(4) The average flow stress is the flow stress multiplied by which of the following factors: (a) n, (b)
(1-n), (c) 1/n, or (d) 1/(1+n), where n is the strain hardening exponent?
(5) The strength of a brazed joint is typically (a) equal to, (b) stronger than, or (c) weaker than
soldered joint?
(6) Thread cutting operation is normally performed on which one of the following machine tools:
(a) drill press, (b) lathe, (c) milling machine, (d) planer, or (e shaper?
(b) In casting experiments performed using a certain alloy and type of sand mould, for
which n can be approximately taken as 2, it took 155 sec for a cube-shaped casting
to solidify. The cube was 50 mm per side.
(i)
Determine the value of the mould constant in Chvorinov's rule.
(ii)
When the same alloy and mould type are used to make a cylindrical
casting of diameter 30 mm, what is the maximum length of the cylinder if
the maximum solidification time is limited to 1 minute?
