METHOD FOR AUTOMATIC RISER GATE REMOVAL COMPENSATING FOR VARIANCE IN CASTING.

摘要

A method of finishing like castings wherein the exact dimensions of the casting (13) are not known requires the steps of traversing the casting along a fixed path impinging excess material (14) on a reduction apparatus such as grinder at a fixed location such that a defined witness (20) is produced on the excess material (14), measuring the difference from the witness (20) to the casting parent material and adjusting the fixed path to remove the excess material (14) to within a specified tolerance.
