Thanks to you who responded to editor Frances Richards in the last
Motion Monitor, where the topic of the next U.S. President's influence
on engineering was discussed. You'll have your next opportunity to
chat with Frances again here in a couple weeks.
Now for those of you that regularly sent parts to a machine shop to
satisfy design part requirements, consider reading a new online PDF on configurable components. In this
new addition to Machine Design magazine's library is presented the idea
that all variables of a design — particularly physical and
mechanical variables — should undergo scrutiny before they're
considered fixed or determinant. In my opinion, this is also an idea
that might be applied to life in general.
As always, we welcome
your comments.

The basic motor types used for the majority of machine
motion-control projects haven’t changed in the last 20 years. The
usual suspects are still the dc servomotor, the brushless-dc motor, and
the stepmotor.
But distinctly different from 20 years ago, and perhaps a little
surprising, is that the choice of motor has little effect on the overall
cost and architecture of the control system.

Within control programs, IEC 61131-3 provides multilanguage support.
So, control program developers can select the language best suited to a
particular task to increase productivity. Too, the IEC 61131-3
standardized programming interface is completely independent of the
hardware platform, so users can also reduce the cost of program
maintenance and training across company-wide automation applications.

Rev up your interdisciplinary design skills
What happens when a microcontroller turns on a power FET, sending a
current pulse to a motor coil that develops a magnetic field which turns
the rotor shaft, advancing a timing belt that drives a pair of nip rolls
suspended on bearings in a web-processing operation on a form, fill, and
seal machine installed on a potato chip line at a Frito Lay plant in
central California? And how can you be sure that the encoders, prox
sensors, and other feedback devices you plan to use will accurately see
and report every relevant motion, machine state, and process condition?
And will the signals get through the networks fast enough, without being
corrupted, giving the controllers time to execute their algorithms as
intended? It's a lot to think about, and it only scratches the surface
of what many engineers grapple with today. If you happen to be one of
them, then the place for you — where you can find answers and meet
others with similar concerns — is www.Mechatronic-Design.com.

Understanding electro-hydraulic application development
Sponsored by EATON
DATE: August 20th, 2008
TIME: 2:00pm ET/11am PT
Learn how the IEC 61131-3 international standard for control programming
is critical for effective implementation of electro-hydraulic systems
and very efficient for the end users. The course will explore the
origins of the standard, demonstrate its relevance to electro-hydraulic
control development and more.

More Machine Uptime through New Developments in Advanced Machinable
Plastics
Sponsored by Quadrant
DATE: August 26th, 2008
TIME: 2:00pm ET/11am PT
Engineers and designers are faced with the constant challenge of
increasing uptime and reliability - while improving the performance of
mechanical systems. New, machinable advanced plastic materials can help
you reduce weight, eliminate costly and complex lubrication systems and
increase the performance of your design. Newer, more cost-effective
materials might fit into designs where before only an exotic polymer
might have done the job. Our speakers will provide an update on new
materials, selection criteria and a few case histories to show how these
new ideas have worked for other designers.

Direct Metal Laser Sintering (DMLS) Gives Designers New Freedom and
Manufacturers a Higher Degree of Quality Control
Sponsored by Morris Technologies
DATE: September 4th, 2008
TIME: 2:00pm ET/11am PT
DMLS is more than a prototyping tool; it’s a viable manufacturing
alternative that can deliver parts in volume with competitive pricing.
Primarily employed for rapid prototyping, DMLS now plays an important
role in manufacturing by delivering parts in volume with competitive
pricing. Applications are wide ranging and include inserts for plastic
injection molding and die casting, as well as direct parts for a variety
of applications and industries including aerospace, automotive, medical,
electronics and many others.
