Article:  "Cures for Cogging in Slotted Linear Motors "

Appeared in:       Motion System Design

This article discusses cogging in slotted iron-core linear motors and several methods used to reduce it, making these motors a viable alternative to more costly slotless ironless motors. We will demonstrate how algorithmic programming is used to solve cogging, thereby making the more economical slotted motors acceptable in applications requiring smooth motion.

Article:  "Applications Dictate Gimbal Selection"

Appeared in:       Laser Focus World

Precision motion control systems have found widespread use in a number of broad markets such as military/aerospace sensor and seeker testing, manufacturing and test/inspection, imaging and optical applications, laser beam steering and focusing, as well as many others. Each of these applications requires certain critical motion performance specifications, and these specifications define the motion technology or technologies best suited for the job. In many cases, one technology becomes an obvious choice. In other applications, two or more competing technologies may each deserve consideration with a comparison of the pros and cons for each. The choice between direct-drive and gear-driven gimbals and optical mounts presents an opportunity for just such a comparison.

Article:  "Minimizing Circular Path Errors in Laser Machining"

Appeared in:       September edition of Industrial Laser Solutions

Laser machining comprises a variety of processes, including laser drilling, cutting, marking, scribing, welding, and micromachining. While a great deal of industry experience exists with these processes, many challenges remain in performing them quickly, effciently, and with the highest process quality. Many factors affect the ultimate part quality, including variations in gas pressure, laser power, material thick-ness, focusing of the laser head, and the motion system.

Article:  "Laser Micro-Drilling Applications"

Appeared in:       ALAC 2004 * ADVANCED LASER APPLICATIONS
                           CONFERENCE & EXPOSITION

This paper describes a system designed for drilling precision apertures in materials with a thickness of 1 mm or greater, and discusses an application example for direct-injection diesel fuel injector nozzles.

Article:  "Smooth Moves"

Appeared in:       Industrial Laser Solutions for Manufacturing

The continuously increasing consumer desire for higher performance automobiles drives requirements for industrial automation and, more specifically, motion control. These motion control automation challenges affect parts manufacturing for fuel injection systems, transmissions, assembly processes, and every other major component in a modern automobile. In this article we focus on the current state-of-the-art in the manufacture of fuel injector nozzles.
