05 Maintenance & Reliability Engineering

Starting with a basic description of the multiple causes of failures, this workshop will emphasize the physical causes and explain how over 85% of all mechanical failures can be solved in the field with minimum complex testing. After a discussion of the metallurgy of common motor and equipment shafts, we will discuss the difference between brittle and ductile materials and how to diagnose whether the failure force was from overload or fatigue. We will delve into diagnosing the specific causes of the failures and look at a series of examples, both with slides and with hands-on pieces. In addition, a series of fastener failures will be reviewed.

The decision making grid (DMG) is a model that classifies maintenance approaches and then help in the selection of the maintenance strategy based on evidence produced from the data collected in Computerised Maintenance Management Systems (CMMS) or Enterprise Resource Planning (ERP)Systems. In this paper we demonstrate three phases for a successful implementation of the DMG model.
