Mobile Apps Moving in for Motion Engineers

Mobile Apps Moving in for Motion Engineers Less than a year ago, ASME noted that of half a million mobile apps available, only a handful served engineers. They've been scarce, indeed, but engineering mobile apps are beginning to arrive. Autodesk is among the suppliers delivering mobile apps with true functionality and time savings for mechanical and motion engineers. Two recent releases should rank high on both cool and useful scales: ForceEffect and ForceEffect Motion. The latter, just released, permits testing mechanical systems with moving parts from iPhones or iPads. They simulate the motion of mechanisms (e.g., actuators, windshield wipers, scissor lifts) helping verify concepts early in the design process.

Their Lips are Sealed, Doubly

Their Lips are Sealed, Doubly They might have had a story to tell, but these encoders' lips are sealed. So, instead of hearing bad news about failure, the report is about consistent positioning accuracy for machining centers. Compressed air in the housing creates a seal between two lip pairs, preventing dust, chips, and coolant from infiltrating and affecting the DIADUR graduation scale.

Precision Steering of Lasers

Precision Steering of Lasers Some lasers are easier to steer than others. For complex movement on multiple axes, this system guides laser beams with precision and corrects position drift. Two piezomotor mirror mounts and two miniature CMOS cameras enable continuous tracking of laser beam positions and profiles. Control algorithms ensure correct beam alignment in both X and Y, and near- and far-fields.

Simplicity Key to Low Cost, High Performance

Simplicity Key to Low Cost, High Performance The simplest electric motor, coupled directly with the load, is the basis for a compact, low cost, high performance stage. Direct coupling enables faster acceleration and higher speeds with zero backlash. These voice coil positioning stages feature hollow cores through their entire body, making them suitable for optical focusing and other apps requiring an axial opening.

Good Guidance for Big Rig Cables

Good Guidance for Big Rig Cables The largest ever plastic cable carrier was a highlight in Houston's recent Offshore Technology Conference. The E4-350, available from stock, is designed for the toughest conditions that industry or nature can sling — ice, wind, seawater, storms, oil, and drilling mud. The drag chains can travel up to 2,600 ft., preventing cable from whipping, swinging, or tangling.

Exlar Tritex II™ DC Powered Actuators
Two-speed Gearbox
ZF Services North America, LLC

Exlar Tritex II™ DC Powered Actuators Exlar's Tritex II™ DC Powered line of actuators integrates power and control electronics with brushless servo motors and actuators in one compact package. Their next-generation design merges power with efficiency and cost-effectiveness. Plus, offering a wide range of I/O capabilities, the Tritex II DC provides superior control and connectivity.

Two-speed Gearbox The ZF-DUOPLAN two-speed gearbox is mainly used in machine tool drives. The gearbox can be used in turning machines (horizontal B5) or machining centers (vertical V1) thanks to its variable installation position. The gearbox is also suitable for use in many systems where torque increase and/or speed reduction is required. From ZF Industries.

Motion Controllers . . .

Advanced Motion Without Programming

Advanced Motion Without Programming The Melsec L series was already a powerful controller with many built-in features. By adding a simple motion module, Mitsubishi has now made the programmable device easier to tweak to achieve optimum performance — without programming. Engineers can establish position, speed, torque, cam, and synchronous control functions just by using simple parameter settings and a sequence program.

Energy Efficient Control Without DSPs

Energy Efficient Control Without DSPs It's easy to be swept into the DSP hoopla. But in some variable speed applications, modern microcontrollers have an advantage. This new 32-bit chip, for instance, features high-speed PWM, customized ADCs, and specialized timers. Onboard, there's enough for the OEM to eliminate DSPs, reduce the BOM costs, and provide energy-efficient drive for DC motors.

ServoBelt Rotary Keeps the Slop Out

ServoBelt Rotary Keeps the Slop Out Mike Everman learned how to banish backlash when working on Space Station projects, where "all motion systems had to have absolutely zero slop." Here, he describes the best ways to eliminate backlash and improve the accuracy of belt and linear drives, then introduces Bell-Everman's first true rotary servobelt drive, one that delivers 15 arc sec repeatability.

Two Walls are Better Than One

Two Walls are Better Than One Not many motion components come with built-in insurance, but two-walled cylinders do. This doubled-walled cylinder features an aluminum outer shell that's epoxy coated, the front line in protecting the inner 304 stainless steel body tube. It is designed for applications where cylinders are at risk of damage by outside forces, such as industrial vehicles or heavy equipment.
