Failure Modes and Effects Analysis (FMEA): The Heart of an Equipment Maintenance Plan By Michael W. Blanchard, CRE, PE, Life Cycle Engineering. The primary purpose of an equipment maintenance plan (EMP) in a manufacturing facility is to minimize the impact of unplanned events on safety, the environment, and business profitability.
believe that the use of Machinery FMEAs will provide a disciplined approach to preventing problems early in the design phase of the machinery where action steps can be more readily taken to produce robust machinery designs. The Machinery Failure Modes and Effects Analysis (MFMEA) has been developed by the Ford Motor

HISTORY In 1775, John Wilkinson- cannon boring machine (lathe). In 1881, Eli Whitney- milling machine. In 1947, Mr. John Parsons began experimenting for using 3-axis curvature data to control the machine tool motion for the production for aircraft components. In 1949, parsons- first NC machine. In 1951, MIT was involved in the project. In 1955, after refinements NC became available in
15 Costly Grinding and Polishing Troubles – How to Avoid Them Scratches, smearing, staining and deformation are just a few of the troubles you want to avoid when grinding and polishing for materialographic analysis. Don't miss these important tips to avoid the 15 most common grinding and polishing troubles.
Job Hazard Analysis (JHA) How to analyze health & safety hazards at your worksite Division of Occupational Safety & Health (DOSH) What is Job Hazard Analysis (JHA)? It is a method for systematically identifying and evaluating hazards associated with a particular job or task. It is also called "job safety analysis (JSA)".
MACHINE SAFETY. Introduction Unguarded moving parts of machines/equipment and the sudden or uncontrolled release of their power systems can result in serious injuries. ... Safe work practices -Grinding machine • Grinding too high above the center of a wheel.
Common shortcomings of equipment troubleshooting are discussed. A case study consisting of a pump motor (bearing) failure is followed, using Equifactor® and human performance root cause analysis to find the real reasons and root causes for the equipment downtime and component failure. Equipment Troubleshooting Equipment Can't Talk, But ...

Metal failure is a common phenomenon when a metal component is subjected to cyclic stresses or overloading. In this article we discuss how to perform a metal fatigue failure analysis to determine the reason for the failure. By this we can be able to take necessary corrective action in design, maintenance, and operation to avoid another failure.
Reference 1 is a basic guide to follow in various stages of a failure analysis investigation. It must be emphasized that the most important initial step to perform in any failure analysis investigation is to do NOTHING, simply study the evidence; think about the failed part or parts; ask detailed questions about the parts, the machine itself ...
What is Machinery Failure Mode and Effects Analysis (MFMEA) Machinery FMEA is a methodical approach used for identifying risks associated with machinery and equipment failure. The purpose of the MFMEA is to increase reliability of the machinery, reduce time to repair and add prevention techniques, such as diagnostics.

Machines fail for a variety of reasons. Likewise, not all failures are the same. The term "machinery failure" or "malfunction" usually implies that the machine has stopped functioning the way in which it was intended or designed. This is referred to as "loss of usefulness" of the machine or component.

Grinding flat or plane surfaces is known as surfaces grinding. Two general types of machines have been developed for this purpose; those of the planer type with a reciprocating table and those having a rotating worktable. Each machine has the possible variation of a horizontal or vertical positioned grinding wheel spindle. The
