Question

Narrowing the range of required dimensions make the casting more expensive and difficult to produce.

(a) True

(b) False

This question was posed to me in my homework.

My enquiry is from Dimensional Inspection topic in section Inspection Testing in Foundries of Casting-Forming-Welding I

Answer 1

The correct option is (a) True

For explanation I would say: The range between the lower tolerance limit and upper tolerance limit is always set by a producer to make dimensions to come within the range, but the narrowing or shortening of range makes the casting more expensive and difficult to produce, and problems also arise while testing of casting.
