______________ is used to reduce the chances of damaging the mould cavity. Correct Answer Draft Allowance

At the time of withdrawing a pattern from the sand mould, the vertical faces of the pattern are in continual contract with sand which damages the mould cavity. Hence the pattern is tapered from the parting line and it is called as the draft allowance.
