Question

Since wood is expensive for larger castings, __________ is used instead of a full pattern.

(a) Loose piece pattern

(b) Segmental pattern

(c) Match plate pattern

(d) Skeleton pattern

This question was addressed to me by my college director while I was bunking the class.

This question is from Pattern Making topic in division Testing of Materials, Foundry & Powder Metallurgy of Engineering Material & Metallurgy

Answer 1

The correct option is (d) Skeleton pattern

Best explanation: For larger casting of a simple shape in a solid pattern, a large amount of wood is required. This, therefore, increases the cost of operation. In such cases, skeleton pattern is used, which is simply a ribbed frame of the desired casting.
