Question

A Fillet is provided in the finishing of a pattern which is very small for shallow castings.

(a) True

(b) False

This question was addressed to me in an interview for job.

This intriguing question originated from Finishing Patterns & Storing of Patterns topic in section Pattern and Pattern Making of Casting-Forming-Welding I

Answer 1

The correct answer is (a) True

To explain: Intersecting surfaces forming junctions of metal thickness are usually joined with fillets in order to avoid high stress concentrations in the metal casting. Shallow castings commonly have much smaller fillets, while the deep pockets and other interior complex corners may have larger fillets.
