Cross-Training Made Possible by Common Control Platform

  • Magazine Article
  • TBMG-34579
Published 2019-06-01 by Tech Briefs Media Group in United States

EMAG L.L.C. is the U.S. subsidiary of a major German machine tool builder that specializes in machine tools for the production of automotive, off-highway, agricultural, and oil field components. The company’s equipment ranges from basic round part turning centers to large-workpiece, five-axis machining centers; gear hobbing machines; and alternative equipment such as laser welding and electrochemical machining centers. This wide variety of machine tools requires an assortment of control technologies to power and manage the motion. For one customer requirement where a major agricultural equipment builder needed grinding, turning, and turn-grind machines, EMAG looked to Siemens for a standardized CNC solution.

 

Industrial Blue Lasers

  • Magazine Article

Published 2019-05-01 by Tech Briefs Media Group in United States

Industrial lasers are integrated into manufacturing and fabrication facilities around the world. Every moment, there is an industrial laser somewhere that is cutting, etching, or welding. But the energy from traditional industrial lasers is not absorbed well by copper, so using them for copper processing has been slow and produced inferior quality.

Dynamic Modeling of CNC Drive Systems: Comparison of Two Models

University of Detroit-Mostafa Mehrabi
Published 2019-04-02 by SAE International in United States
Accurate positioning and precision of CNC machines are directly affected by performance of their mechanical drive system and control unit (CNC feeddrive system). This is more important in contouring operations where axes motion is synchronized by interpolators and errors are accumulative. This research work is focused on study of dynamics of the feeddrive unit. In this regard, a detailed dynamic model is developed in state-space format that is used to study its response properties. A parametric study of the system is carried out by studying shifts in eigenvalue loci when a parameter is changed. The results are used in further simplifying this model to a reduced order system which is simpler in structure and more appropriate for control applications. A comparison is made between these models and the merits of each individual model are presented.

A Process for Delivering Extreme AFP Head Reliability

Electroimpact Inc.-Todd Rudberg, Joshua Cemenska, Ethan Sherrard
Published 2019-03-19 by SAE International in United States
Every now and then a good idea happens. The Modular head was a great idea and enabled the use of multiple types of AFP heads, ATL, ply cutting, part probing, etc. with the use of a single machine and machining cell. At the time the modular head was developed by Electroimpact circa 2004, the industry assumed (and accepted) that AFP was an unreliable process. It still isn’t as reliable as we’d like. One way of coping with this lack of reliability is to stage more than one head in the AFP cell so that a spare head of the exact same type is ready to jump into action if the head out on the floor has an issue. If the reliability of the AFP process were to increase 10x or 50x, would there still be a business case for the multiple AFP head system? The modular head may still win the day, but the metrics change. For instance, if there was only 20 minutes of down time for every head load, it may no longer…

Manufacturing: Tooling Up for Success

  • Magazine Article
  • TBMG-33736
Published 2019-02-01 by Tech Briefs Media Group in United States

In the medical industry, metal parts play an integral role in a vast array of diagnostic, testing, medical instruments, and equipment. Although certain complex metal parts can only be machined, thinner gauge parts and enclosures are typically stamped using hard tooling or fabricated using lasers, turret presses, or press brakes. These parts include carts, cabinets, enclosures, and user workstations that safeguard sensitive controls, electronics, or hardware. While not as high tech as the diagnostic equipment itself, these structural components are still critical to the product's function and longevity.

 

Custom Optomechanics in Industrial UV Lasers

Published 2018-11-01 by Tech Briefs Media Group in United States

Reliability and longevity directly impact the cost of using Q-switched, diode pumped, solid state, ultraviolet lasers in industrial applications. Damage to the intracavity harmonic crystal is often the major limiting factor in the lifetime of these lasers.

 

How Second Stage Speed Influences the Molding Process

Hold speed or hold velocity? How many machines today have it, and what does it do to the process?

 

Motion Control in Factories: Choosing the Right Solution

  • Magazine Article
  • TBMG-33076
Published 2018-10-01 by Tech Briefs Media Group in United States

The need for Ethernet-based communication within the factory has grown over the past 10 years. Detailed information about the tasks and performance of machines at every stage is critical to productivity. As capabilities have expanded from performance reporting to predictive maintenance warnings and beyond, the need to connect multiple controllers within the same machine and elsewhere in the factory has also grown.

 

Collaborative Robots Fill Automation Gaps For Medical Device Manufacturers

  • Magazine Article
  • TBMG-33083
Published 2018-10-01 by Tech Briefs Media Group in United States

When small and mid-sized medical device manufacturers envision a robot, many think of either huge industrial robots working in fenced-off areas in large factories or futuristic cyberbots mimicking human behavior. But between these two scenarios lies a new emerging reality: A class of robots dubbed collaborative robots — or simply cobots — are bridging the gap between fully manual assembly and fully automated manufacturing lines. This new technology is filling automation gaps for larger manufacturers that have processes that couldn't be cost-effectively automated in the past and is bringing the advantages of automation within reach for even small, specialty manufacturers.
