​Students from the University of Tennessee Maintenance and Reliability program visited Arconic last week.

On May 17, Tennessee Operations hosted 20 college students from the University of Tennessee Reliability and Maintenance Center. The students were provided an overview of the operations, took part in a panel to learn more about equipment reliability and engineering careers and toured the Continuous Cold Mill.

Tickle College of Engineering Students tour Amazon’s Distribution Center (CHA1)

On Friday, September 15th, the UT Reliability & Maintainability Center (RMC) took over sixty Tickle College of Engineering students, faculty, and staff to tour Amazon’s Distribution Center (CHA1) in Chattanooga, TN.  Attendees were given a first-hand look at how orders are accepted, fulfilled, and shipped, as well as how inventory is stored and managed at the site.  Participants agreed that it was fascinating to see the working facility of a service that so many of us use on a regular basis.  Most were surprised to find that inventory is arranged randomly, based on space available, with each item’s precise location captured through bar-code technology.

The RMC would like to thank Kym Chavez, Amazon Program Manager – Technical Training and Development for North American Reliability & Maintenance Engineering, for arranging the tour.  A special thanks also goes to the Operations Team at CHA1: Heather Boles, Chris Scanlon, and Brad Allen, as well as the CHA1 Reliability & Maintainability Engineering Team: Tom Wintz, Mike Freeman and Jesse Bratcher, for guiding the tours and answering questions.

Amazon will be hiring 5+ reliability interns for Summer 2018, through the RMC program.  If you would like to be considered for these or other RME positions, please contact Kim Kallstrom at

Motor Circuit Analysis: An Introduction to De-energized Electrical Motor Testing

Managers, engineers, & electricians that are responsible for maintaining electrical motor system operation will benefit from attending this informative introduction to electrical motor diagnostics using Motor Circuit Analysis (MCA) at the University of Tennessee’s Reliability and Maintainability Center’s Parade of Technologies event. We will discuss why electric motors fail and why ohm meters & insulation to ground testers only detect ~10% of motor failures.

Many people think they don’t have time or personnel to dedicate to the task of electric motor testing. However, motor testing using an MCA tool is very easy to implement and the MCA test takes <3 minutes. We will demonstrate why you should grab the MCA tool instead of the Meg-ohmmeter next time a motor system unexpectedly quits running at your facility. MCA can identify a ground fault, but it also evaluates the connections, cables, and detects internal stator winding faults. Moreover, MCA motor testing can be used for Quality Control & Commissioning, Trouble-shooting, and Predictive Maintenance.

This short course will provide you with valuable information to help you understand motor system faults and how to diagnose them. It includes hands-on interactive learning activities to teach what different fault indications mean and how this new information can help you make better decisions about the condition of your rotating equipment.  Case studies from actual field testing will be reviewed and discussed to bring it all together to help you better understand the applications and benefits motor testing will bring to your facility.

ALL-TEST Pro is excited to be back and we look forward to helping you better understand Electrical Motor Diagnostics and how it can benefit you.


Making the IoT work for you with wireless tools, mobile access and cloud-based data management – Frederic Baudart & Samantha LeSesne

Over the past couple of years, Fluke has been working on a wireless tools implementation and condition based monitoring system that connect wireless measurement devices directly to the cloud for remote event monitoring as well as onsite troubleshooting.

The core advantage of wireless data transfer is no more manual import/export, data entry or spreadsheet work, which means fewer errors, greater consistency and a far better view into asset health. Wireless tools also improve electrical safety, and adopting a wireless workflow speeds up problem resolution, smooths out team workflows and almost always contributes to greater predictability and less downtime.

Data collected by wireless tools can be accessed on the Fluke Connect mobile app or through Fluke Connect® Condition Monitoring software. Having a cloud-based data management system allows technicians and managers to see all measurements on an individual asset in one place through data-driven graphics such as trend lines on vibration measurements; electrical, temperature and pressure readings; even series of thermal images over time.

A benefit of continuous measurement is status history that can show change in the equipment’s health and provide justification for a manager’s decision to issue a work order for further troubleshooting, repair or component replacement. Through Fluke’s research with this device and wireless tools, we have found that data management leads to stronger proactive maintenance, increased energy efficiency and higher safety compliance rates. 

Further aspects of the relationship of IoT to wireless tools, mobile access, and cloud-based data management will be discuss during the Parade of Technologies course.

Common reason for unplanned downtime – Michael A Olszewski

The most common reason for unplanned downtime of belt-driven machinery is pulley misalignment. Pulley misalignment can increase wear on pulleys and belts as well as increasing the noise and vibration levels that can result in unplanned machinery downtime. Another side effect of increased vibration is premature bearing failure. This too can cause unplanned machinery downtime. Traditional belt alignment methods are usually, single laser or visual in combination with a straight edge and/or length of string.

Using a laser belt alignment tool is quicker and more accurate than traditional methods. The unique B.A.T. Belt Alignment Tool® aligns the pulley faces accurately and quickly as well as providing live feedback on the mechanical condition of the system.

Participants will learn how to apply the dual laser alignment method to many types of belt alignment situations. In addition,  Soft Foot Testing, Offset Alignment, Multiple Pulley Alignment and other techniques will be presented.  Interpretation of the laser results and diagnosis of machinery defects often overlooked will also be explored.

Accurate pulley and belt alignment can result in:

  • Increased bearing life.
  • Increase machinery uptime, efficiency and productivity.
  • Reduced wear on pulleys and belts.
  • Reduced friction and thereby energy consumption.
  • Reduced noise and vibration.
  • Reduced costs of replacing components.
