New Webcast: Acceleration versus Error – Balancing Performance for Cylindrical Laser Processing Applications

Aerotech’s Scott Schmidt, Laser Processing & Micromachining Group Manager, presented a webcast on May 12 titled Acceleration versus Error – Balancing Performance for Cylindrical Laser Processing Applications. Anyone interested in improving their cylindrical laser processing application can reap valuable information on how to improve their process. While the discussion centered on stents, the lessons learned are … Continue reading New Webcast: Acceleration versus Error – Balancing Performance for Cylindrical Laser Processing Applications

Which is the Perfect F-Theta Lens for my High-Speed Scanning Application?

Modern high-speed and high-precision galvanometer applications demand carefully considered choices for all system components. For instance, galvo motors inside the laser scan-head are optimized for best possible dynamic performance, the galvo mirrors mounted on those motors are constructed from best-in-class materials offering outstanding stiffness and exceptionally low inertia, and the mirror coatings are engineered dielectric … Continue reading Which is the Perfect F-Theta Lens for my High-Speed Scanning Application?

Webinar – Nanometer-Level Positioning: A Mechatronic & System Design Approach

Nanopositioning, or moving objects with atomic-scale precision, is a key enabling technology in areas such as semiconductor processing, microscopy and nano imaging, hard-drive and electronics manufacturing, and medical device manufacturing. The ability to reliably position a sensor, tool, or part to nanometer-level tolerances requires a deep understanding of all components in a motion system. As … Continue reading Webinar – Nanometer-Level Positioning: A Mechatronic & System Design Approach

6 Reasons Your Motion System May be Underperforming

Building the best motion system for your needs can be a real challenge. But there are a few key things to consider when designing a system that will ensure you have the best motion system for your application. 1. Stiffness First thing’s first. How stiff is your system? The primary cause of poor motion control is that your … Continue reading 6 Reasons Your Motion System May be Underperforming

Theory and Application of Piezoelectrics in Positioning

In 1880, Pierre and Jacques Curie discovered that when mechanical stress was applied to a crystal, faint electric charges developed on the surface of that crystal. As the prefix “piezo” comes from the Greek piezein, which means to squeeze or press, the term “direct piezoelectric effect” was coined to describe the electrical charge that is … Continue reading Theory and Application of Piezoelectrics in Positioning

Motion Basics: Calibration and Error Correction

A mechanical system can often be highly repeatable, but not necessarily accurate. Fortunately, its repeatability – the ability to reliably return to a given position – gives us a means to improve the accuracy. In an earlier Motion Control Basics video focused on Accuracy vs. Repeatability, we used a dartboard to illustrate the difference between two specifications … Continue reading Motion Basics: Calibration and Error Correction

Motion Basics: How to Describe the Orientation of your Rotary Stage

In motion control applications, the orientation of a rotary stage is often misstated leading to confusion and, in some cases, a stage that is not properly sized for the application. It’s common to hear phrases such as “normal,” “lying flat” or “tipped on its side” used to describe the orientation. However, to avoid confusion the … Continue reading Motion Basics: How to Describe the Orientation of your Rotary Stage

Motion Basics: Accuracy vs. Repeatability

In the automation world, there are terms that people use interchangeably, but in fact mean very different things. For example, ‘accuracy’ and ‘repeatability’ – two of the most important specifications when selecting a rotary or linear stage.

In this Motion Control Basics video, we explain the difference between accuracy and repeatability, and show you how it relates to linear-stage travel.
