Gears. Surface temper etch inspection after grinding, chemical method Ingestion-build-258901 measuring and calibration requirements and1 Scope This document specifies procedures and requirements for the detection and classification of localized overheating on ground surfaces by chemical etch methods. The process described in this document is typically used on ground surfaces; however, it is also useful for the detection of surface anomalies that result from post heat treatment machining such as hard turning, milling and edge breaking (deburring) processes.
