Volume 14:
Welcome:
Please select "subscribe to newsletter" on our contact form. Topic: Lubrication and PLCsWelcome to the 14th issue of our Feed Forward Newsletter; "The Maintenance War Newsletter". This first area of the newsletter is for introductions and commentary. Remember, the website has many new items added each month. So please browse around and find yourself quality maintenance and engineering information.Online version at www.feedforward.com.au
In line with the theme of this issue, we are giving away a free Bearing Lubrication Simulation Software CD with any CD order for the entire month of July. (Limit one free CD per customer.) We will also have 5 drawings for a free "Pocket Maintenance Advisor - hard copy" at the end of July. To qualify you need only make a purchase during the month of July.
I would also like to take this opportunity to tell you about the new 'Kaizen Corner' area of a website by Author - Larry Bush www.reliability-consultant.com/Kaizen_Corner.htm My personal favorite out of the 8 Kaizen listed so far, is the one titled "THE NON-WRAPPING STRETCH WRAP MACHINE" . What an excellent example of not only the cost of not updating your PLC equipment, but also the cost of not training your people on the PLC equipment. Working with a PLC without really understanding what you are doing can cost much downtime. Also typical, the failure occurs on an off shift, when the OEM is not available. (What really hurts is when you find support is even more difficult to find because the OEM for the outdated equipment, is out of business.) Yes, another example too, the value of performing a plant wide PLC assessment of your equipment. You can download this PLC assessment - free spreadsheet we use to collect vital info on the PLCs in a facility. (So why not take pro-active action today!) Management Help: OEE is a Benchmark toolOne reader asks: "We have tube making lines running 24hrs a day, 5 days a week." We work our OEE out by the simple formula If we run nonstop at best speed all week (unlikely) then we get 100% OEE But we find that several factors impinge on our formula:- 1)
Different jobs run at different speeds To keep things simple we continue to use our OEE formula but I do wonder if we should be varying the parameters such as best line speed and actual running days. The issue is with several lines this gets very difficult to track. Any thoughts that might help. Regards, Dean" Hi Dean: Your answer is definitely, 'Yes'. The primary purpose of OEE is to be a Benchmark tool to compare Apples to Oranges. :>) Now the above is a general answer, to do the best you can, my answer would provide a little more detail. :>) The secondary goal of using OEE to is to drive one to get the most value out of company equipment/facility as one can. To better reach this goal, some of the fortune 500 companies have developed a second benchmarking measurement tool daubed, 'TEEP'. Please see http://www.downtimecentral.com/oee_teep.htm for more detail. If you have the same equipment running different products which each product runs at different speed, you want to use OEE to show you what is your most profitable product. (IE: if equipment is designed to run 30 pieces per minute, and one product requires you to slow equipment to 15 pieces per minute to maintain quality, that product process needs analyzed to improve speed.) As a side note, maybe after much study, the speed for the slower product could not be improved. Then that lower OEE may be a consideration when pricing that more costly to produce product. Where TEEP comes into play is that it uses scheduled production time not 24/7. I noticed you did not mention quality in your original question, but you being Six sigma, I am sure you intended that quality being used in the OEE was assumed. :>) So in summary, I would recommend both OEE (24/7) for equipment utilization (ROA) and TEEP for weekly benchmark (setting speed factor by product) for operating efficiency. My Quote "Nobody runs 100% OEE, because nobody is perfect. There is always room for improvement." Also see OEE analysis for more insight and read "What is the True Downtime Cost (TDC)?" or download the book. Hope this helps Human Resource:What are SOP's, Procedures and Work Instructions?Reader Kon S. ask "What are the differences between SOP's, Procedures and Work Instructions?" Don's Reply: SOP's are Standard Operating Procedures. Which are procedures (written work instructions) that all follow to give more consistency and control to the process. Kon elaborates... "I have seen companies call there documentation work instructions, other companies call them procedures and other companies call them SOP's." Don further replies ... I believe I will stick with my first opinion. They are all basically the same and left up to the interpretation of the one's requesting them to be written. In many cases, "work instructions" may be just a 'How to' with less focus on standardization by the author. A less formal version of the SOP. The use of just the word "procedures" being somewhere in the middle, with "SOP" being the most detailed version with the most focus on standardization. You will probably find the more formal (and descriptive) terminology "SOP" used more in cases where ISO certification and Corporate guidelines are involved. Hope this helps Don
Employee Training and Development with SOP eBook By Mike Sondalini - Discover how to realize and release the continuous improvement power of a Standard Operating Procedure (SOP). The World Wide Web: You can pick up the news paper or a trade magazine and read the front page news or cover story of what that establishment feels is a hot topic. The truth is you may get an impression of what is a hot topic in our industry, but in actually, the topic decision was biased, paid for, or just one editor's opinion. The internet has some excellent tools for finding out what is truly the hot topic of focus for our industry, and it will be completely unbiased. Take for example Overture's "What's most search for" tool. Below are fairly new topics that are being most searched for by individuals from around the world in our industry. You might find them informative and interesting. shanghai automotive industry corp automotive closing general motor plant And it is always interesting to know what topic (relevant to our industry) is the 'most search for' in the basic categories of industrial, engineering and maintenance. This gives you a sense of what relevant topic mater has the most internet presence. (law of supply and demand.)
