Question

In pattern making, the term used for rounding out of external edges of the pattern is called as a fillet.

(a) True

(b) False

I have been asked this question during an internship interview.

I'm obligated to ask this question of Pattern Fillets topic in chapter Pattern and Pattern Making of Casting-Forming-Welding I

Answer 1

The correct choice is (b) False

The explanation is: The term used for rounding-out of external edges of the pattern is basically known as radii, and the rounding-out of internal corners of the pattern is known as the fillets on the pattern. Fillets are mainly provided to make uniform heating and cooling of the casting material and also for the less stress concentration.
