Pick-and-Place System Delivers Improved Productivity and Safety

Deciding between a gantry and a robot for your application isn’t always as clear-cut as it may seem. To automate a simple, yet time-consuming and potentially dangerous task in its factory, a company that makes particleboards weighed the benefits of using a gantry system against a robot system.

Miniature Linear Bearings Help Prolong Curiosity’s Mars Mission

The launch, landing, and overall mission of NASA’s Mars Science Laboratory (MSL) is arguably one of the most daring — and successful — space exploration endeavors ever undertaken. After a successful landing at Gale Crater on August 6, 2012, MSL’s Curiosity rover has already surpassed its 23-month mission target, and it continues to transmit informative images of the Martian surface on a daily basis.

Nano-Motion Stages Rely on High-Precision Encoders for Accuracy and Repeatability

ALIO Industries designs and builds very high precision automation stages for nano-level manufacturing and research applications, including microlithography, medical devices, and micro-machine tools. In this world where a misalignment of one micron might as well be one meter, Renishaw encoders have played a vital role in the performance of ALIO's True Nano™ and 6-D Nano Precision™ motion systems (Figure 1).

Motor Control Technology Boosts Performance of Remotely Piloted Aircraft

PC Krause and Associates
West Lafayette, IN
For more info click here

With support from the Air Force Small Business Innovation Research/Small Business Technology Transfer (SBIR/STTR) Program, PC Krause and Associates (PCKA) has developed a system that could meet a wide range of small aircraft electrical power and propulsion system needs. The company was aiming for its new modular motor drive system to fill the gap between existing commercial equipment and custom solutions at a cost that is viable for most remotely piloted aircraft (RPA) platforms.

Oil Sheer Clutch Cuts Downtime for Metal Stamping Press

In the metal stamping business, precision, repeatability, and uptime are key. But stamping accuracy suffers when improper tension on the coil feeders incorrectly supplies metal to the presses, resulting in off-spec parts and increased rejections. ART Technologies of Fairfield, OH, relies on an oil shear clutch brake to supply constant, reliable tension on the coil feeding to one of its 400-ton presses to produce the precision and repeatability it needs, with no downtime for maintenance or adjustment. When the plant is working 20 hours a day, that uptime is as critical as the tolerances it maintains.

Custom Brakes Meet the Challenges of Gearless Motor Elevators

A manufacturer of low and high-rise elevators faced a challenge when customers began calling for a flexible elevator to meet the needs of the growing mid-rise, mixed-use building market. The global construction boom of mid-rise buildings can be attributed to several factors. Developers are more apt to build “short” because it requires less capital and the time to get permits approved is reduced considerably, especially in developing countries.

Custom Machines Create Engine Lip Skins on Boeing Aircraft

MJC Engineering, a custom machine tool builder in Huntington Beach, CA, specializes in metal-spinning machines for such applications as sheet spinning, flow forming, wheel spinning, and rotary forging. The company was commissioned to build a series of metal-spinning machines for GKN for use at its plants in Camarillo, CA and Orangeburg, SC. These machines produce lip skins for the engine housings on Boeing 777X and 737MAX aircraft. Using CNC from Siemens Industry (Elk Grove Village, IL) and robotic handling technology — in addition to its proprietary servopump-controlled Green Power™ hydraulic power unit that saves up to 40% on energy — the MJC team devised a unique solution to an engineering challenge brought to them by GKN.

Motor Controller Provides Custom Electronic Control Solution

A Fortune 200 company needed a turnkey, DC voltage, agency-compliant electronic control solution capable of providing motion control with memory position capabilities and auto run/sense features for a multi-motor application involving four motors. Particularly important to the design criteria was the development of an interactive system of wireless remote control capabilities and other user interface devices, including iPhone and iPad interconnect devices. It was a complicated job, and the company would need to partner with experts who could deliver a time- and cost-effective solution.

Multiphysics CAE of a Shock Absorber

Shock absorbers are important parts of vehicles. The shock absorber is used to observe the vibrations from shock loads due to irregularities of the road surface, and operates without affecting the stability, steering, or handling of the vehicle. Generally, for light vehicles, cylindrical coil springs are used as suspension elements. The application described in this article attempts to analyze performance of a shock absorber with different suspension springs. This analysis includes comparative modeling and analysis of solid height, damping performance, oscillation capabilities of closed coil conical and cylindrical compression springs, and a suggested suitable design for improved performance.
