A stepmotor divides a full rotation into a large number of steps instead of rotating continuously like a regular electric motor. They are very useful in positioning systems particularly in digitally controlled servo systems. A hybrid stepmotor...
The decision to update CAD software is a serious undertaking. Companies going through the upgrade process need to consider the cost of the new software, any new hardware requirements, user training and converting legacy documents. Improper planning could result in more costs than benefits. Another risk is the new software will not work in the company or...
The manufacturing sector in this country has been diminishing due to a mixture of finding cheaper labor elsewhere and containerized shipping. The driving trend is now to get the highest quality product for the cheapest cost without regards to where it is manufactured. Many U.S. companies have found the solution to this is by moving their manufacturing...
When hiring a consultant, organizations should look for the following attributes to guide their decision: a wide variety of experiences, an unbiased approach with a variety of techniques, first hand knowledge of what approaches do and do not work, and the ability to stay focused on solving the problem at hand. Once a consultant has been chosen, the...
Do engineers need a union? According to this article, the workplace is rapidly changing and union membership can have important benefits. For instance, unions can make obtaining career goals easier. Joining a union gives engineers more of a voice in corporate boardrooms where they might otherwise be ignored by management. Not to mention that unions can...
Recent development of a minuscule pump has created a great deal of excitement. The microscopic peristaltic pump that is smaller than a penny is reputed to be the smallest pump in the world. The pump was created by president and founder of MicroDysis Inc., Joseph Z. Huang, who has more than 20 years experience in biomedical instrumentation, medical...
Smart fabrics are textiles that can carry data and electrical power. By allowing the textiles to be conductive to electrical charges and data signals, they can then be used in applications such as flexible sensing systems, chemical detectors, or mobile power generators. Smart fabrics are usually constructed from a blend of textiles and electronically...
This article is intended to help ordinary users understand what software validation is all about, how to go about it, and what projects to leave to the software engineers. Software validation in the medical device industry is critical to the proper functioning of medical equipment. It is also FDA mandated that any software which automates any process...
This article explains how modern CAD systems can be used to design mechanical linkages quickly and easily. As one can imagine, this is very good news to anyone involved in machine design. The program can handle all the calculations which will free the user to focus on other things while at the same time reducing the possibility of random calculation...
A common misconception is that stepmotors offer improved accuracy and better torque. This article discusses important factors that will help machine designers get the best possible accuracy with stepmotors. The step angle is critical in determining how the step motor will function. Half stepping can cause unexpected issues. For example, if a 1.8-degree...
In the past, software limitations required that design engineer’s layout their machine design and then wait for the analysis. Even in recent years with high speed computing, there was still a time lag between the design and analysis. This is due to the finite element method of analysis on which these programs are based. The article discusses how...
