Four Ways to improve Production by Understanding the Physics of Servos

There is always a need to increase production in automation applications. Sometimes achieving improvements requires breaking the process down to its fundamental basics. The science behind the technology of servo-based motion control systems should be considered when attempting to eliminate inefficiencies. Four fundamentals to examine are inertia, resonance, vibration suppression, and regeneration.

Converting from Hydraulic Cylinders to Electric Actuators

Advances in motion control technology have prompted a new debate — do hydraulic cylinders or electric linear actuators offer the best solution for a linear motion application? Hydraulic cylinders provide high force at an affordable cost. Hydraulics are rugged, relatively simple to deploy, and deliver a low cost per unit of force. However, electric rod actuators (electric cylinders), particularly those with roller screws, have attained increasingly higher force capacities while becoming more flexible, precise, and reliable.

High-Power Fiber Lasers

High-power (multi-kW) fiber lasers are revolutionizing industrial materials processing markets by offering an unmatched combination of performance, reliability, and cost advantages. For example, in sheet metal cutting (the largest application, with more than $1B/year of laser sales), fiber lasers provide the highest cutting speed (especially for thin sheets, the dominant application), scalability to thick sheets (>1”), and the ability to process a wide range of metals with a single tool. Along with low power consumption and high reliability, these capabilities result in the lowest cost per part. Fiber lasers have thus been the fastest-growing segment of the laser market for the past decade.

Finding the Right Chip-on-Tip Camera Technology

You have a great idea that could potentially revolutionize your industry: a new surgical technique, diagnostic solution, or inspection system. You already know getting there will require the latest video imaging technology from an incredibly small, sub-millimeter, package; in other words, a distal chip-on-tip (COT) video camera. The COT needs to integrate into an elegantly designed, flexible device and allow video imaging into anatomy that was previously inaccessible, or image into the tiny dark crevices of our mechanized world. The technology has to be inexpensive, yet video performance needs to be competitive with larger sensor video products with which the market is already familiar. (Figure 1). So, where do you start to identify appropriate video technologies and vendors?

Infrared Cameras Support Advanced 3D Printing Efforts

Additive manufacturing (AM), also known as 3D printing, is quite literally one of the most innovative technologies revolutionizing manufacturing today, in terms of both industry “buzz” and thermal properties. Unlike subtractive manufacturing methods such as machining, the growing range of AM technologies creates components directly from a computer model, adding material only where needed. Wohlers Associates, a leading independent consulting firm focused on these technologies, is forecasting that the value of the worldwide AM market will grow to more than $10.8 billion by 2021, up from just $2.2 billion in 2012. That rapid escalation, however, isn't the result of hobbyists buying desktop 3D printers that cost a few hundred dollars.

CERTIFICATES AND SIGNATURES: How to Ensure Authentication in the IoT

On October 21, 2016, the Internet saw a significant distributed denial of service (DDoS) attack, conducted via a botnet comprising many co-opted Internet-connected devices. The attackers of the network infrastructure were able to control these Internet-of-Things (IoT) devices for a number of reasons, including a lack of strong authentication. Loaded software turned the machines into puppets that interfered with Internet traffic for millions of users.
