failure, how far it has progressed, and the cause and cure of the ailment. This article rounds up every type—and the ma- jor stages—of gear failures. Included are photo- graphs of actual failures, along with probable cause and the most effective remedies. GEAR has failed when it can no longer efficiently do the job for which it was designed.

Cross-machine tension burst. An irregular separation or rupture of the web. While the defect is normally in the machine direction, the fiber separation is in the cross machine direction. Normally this defect is not visible at the edge of the roll. An abrupt change in cross-machine caliper: Minimize cross-machine sheet caliper variation.

Theory of Metal Cutting 1. Many components produced by primary manufacturing processes need machining to get their final shape, accurate size and good surface finish. The term machining is used to describe various processes which involve removal of material from the workpiece Definition of Machining (or Metal cutting) "Machining is an …

The statistical analysis of equipment aging characteristics, regression techniques of equipment operating parameters related to failure rates, and analysis of field failure data have been studied in attempts to develop a methodology that can be used to evaluate a new mechanical

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

analysis, a failure condition has to be defined too. It is directly derived from the deterministic relation and the failure condition is defined by a new random variable G. For example the random variables corresponding to the deterministic relations in (2.2) are: G 1 (R,S)=R−S or G 2 (R,S)= R S −1 (2.3)

The objective of the analysis was to identify critical failure modes, components and sub-systems. The study uses field failure data from more than 50 CNC turning centers and more than five ...

Introduction teria based on rms levels of vibration within unspecified fre- V quency bands can be misleading. IBRATION levels on machine frames and bearing The objectives of the work described in this paper were firstly, housings provide a useful guide to such things as state to review the general problems of vibration measurement and of balance and alignment of …

Machine Safety * Motion may strike or catch an employee in a pinch or shear point created by the moving part and a fixed object. Machine Safety * Machine Safety * The hazard occurs at the point of operation where the employee typically inserts, holds, or withdraws the stock by hand. Machine Safety * Press Brake – personal picture.

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. 1. TROUBLESHOOTING - …

analysis is currently applied in many fields such as aeronautics, nuclear industry, petrochemical industry, etc. The technique provides a graphical aid for the analysis and it allows many failure modes including common cause failures. FTA is widely used in the design phase of nuclear power plants, subsea control

The FAFG will engage with other MFPT Focus Groups to show why failure analysis is an integral part of the product life cycle. About the Focus Group: Our network is over 55 members strong. Various backgrounds: failure analysis, failure modes, metallurgy, tribology, optical and electron microscopy, heat treatment, materials processing.

Fred K. Geitner, Heinz P. Bloch, in Machinery Failure Analysis and Troubleshooting (Fourth Edition), 2012. Vibration. Rolling bearings exposed to vibration while the shafts are not rotating are subject to a damage called false brinelling. The evidence can be either brightly polished depressions or the characteristic red-brown stain of fretting.

Reach down into metal box to left of grinding machine, grasp casting, and carry to grinding wheel. Step 2. Push casting against grinding wheel to grind off burr.

persulfate process to detect grinding burn. The DOE was a full factorial with replication, two levels per factor, with center point. The variables were % ammonium persulfate and % HCL. The response variable was burn indication (faint, light, dark). The etch process was replicated in the Failure Analysis Laboratory as

likely failure modes. More effective when preceeded by a root cause analysis. • Conducting the analysis too early or too late • Spending too much time spent assessing likelihood . • SFMEAs are NOT used to calculate failure rates. Once root cause of failure mode is removed correctly, failure event doesn't recur.

Guidance Notes on Equipment Condition Monitoring Techniques. is to provide a single ABS document containing information related to the subject and to be used as a resource ...

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.

Equipment breakdowns reduce the availability factor of OEE. Root cause analysis is a lean tool used to identify the root causes of problems so that the problems can be eliminated at their base. In this project, root causes of equipment breakdowns have been analysed and vital counter measures suggested to eliminate the root causes.
