Moving the mouse over any of these links activates a pull-down menu. Click Courses. Visitors can then scroll down the page to read an Overview, Course Outlines, Schedule and Feedback. Overview gives a brief explanation of the course content. Courses focus on lean manufacturing. On the home page, click Resources for a guide to sources of hardware devices used in lean manufacturing, industry associations and Commercial sites related to lean production. Under Discussion, visitors can post or search articles or reply to an article.

Need Some Help?
This month, Quality Online visitor Mohsen Zandieh needs some help. Here's his query: "How can we define measurable quality objective in a small organization?"
Can you help Mohsen or any of our Quality Online visitors? Go to the Reader Forum (http://www.i-boards.com/bnp/qm) and post your quality and manufacturing problems, or see if you can help a fellow visitor.
From Wes Iversen, editor of Quality, posted on the "Reader Forum." Quality is celebrating its 40th year of publication. We plan to take a look at the people and events that have shaped the quality movement. What do you think are the most significant events and trends that have impacted quality--either positively or negatively--over the past 40 years? Which individuals have had the most impact on the quality movement during that time and why?
Please post your answers in Reader Forum. Go to http://www.i-boards.com/bnp/qm.
One response came from Reader Forum visitor Thomas Berilla regarding the trends that have shaped quality during the past 40 years.
In the past 40 years, dozens of different methods have been developed and included in the ASME 14.5 Dimensioning and Tolerancing Standard to such a degree that it is not a "standard," but a dictionary of many standards. Most of the methods produce ambiguities and corruptions to designs and their methods of measurements, which produce less than optimum quality control, incorrect fits, poor product performance and less than optimum cost. The latest methods are not as good as our grandfather's methods. I have rediscovered from 200 years of history that the method used to create the industrial revolution is the American system. Quality must help rediscover the American system, compare it with all other methods, evaluate it, and then select the best method and make "it" the standard--scrapping the rest. I believe, the "D&T With the Basic Method" (Apr. 2001, p.102) does this. If another is better, then let it be the "standard."
From "Reader Forum" visitor Arnie Johansen.
Q: Does anyone know of software for a coordinate measuring machine (CMM) that gives measurements based on Y14.5M-1994? If I understand the standard correctly, a plane is defined by a minimum of the three highest points on the surface. A CMM only uses the points on the surface that an operator probes. There is no guarantee that an operator has hit the three highest points. Also, if the operator hits many of the points, a lot of programs use the least squares to define the plane. Perhaps an operator may simulate the plane by placing the part on a relatively flat surface and then probe that flat surface, and assume the three highest points on the part surface touch the relatively flat surface. The same thing is true for holes, which if I understand the standard correctly, are defined by the largest perfect circle pin that fits in the hole. Again, if I probe the hole with a CMM, I am not assured that I have hit the points that a perfect circle pin will touch in the imperfect hole. Any solutions? If the parts were perfect in form, such as perfectly flat, perfectly round and perpendicular to a surface, I could accept the CMM programs I know of. However, we may receive parts that are not perfect, and then the question of measurement of imperfect parts creates a new headache.
An answer came from Quality Online visitor Paul Jackson.
A: The most comprehensive and technically informative material designed to equip CMM operators with knowledge on how to use various software algorithms to extract geometric solutions for such things as tangent plane, related or unrelated actual mating envelope, maximum and minimum inscribed and circumscribed cylinders, is available in a class by Bill Tandler, Multimetrics Inc., Menlo Park, CA. The Web site address is http://www.multimetrics.com/applyingASMEY14.5CMMoper.html #ApplyingASMEY14.5MtoCMMOperation. Bill explains how to use the software in spite of its shortcomings to get the correct result. It is important to note that there are no perfect solutions for evaluating the imperfect geometry because the gages we use are imperfect and the points we gather are finite. It is however, important to understand how the chosen technique for data generation relates to the geometric tolerance specified.
