Robotics researchers from Sandia National Laboratories have developed a small, three-axis sensor that helps monitor fit and movement of prosthetic legs for amputees.

A new process called SmartCleave FI by laser manufacturer Rofin, Plymouth, Mich., utilizes an ultrashort-pulse laser with dedicated properties. The base technology is IP-protected and uses laser filamentation to separate brittle and transparent materials in a high-speed, debris-free, quasi zero-gap process. SmartCleave allows cutting arbitrary shapes, including small radii, in a single pass without taper. The resulting surface finish is basically free of chipping, according to the company.

The Future Interfaces Group at Carnegie Mellon University presents “Skin Buttons,” tiny laser projectors integrated into a smartwatch to render icons on the user’s skin. These icons can be made touch sensitive, significantly expanding the interactive region without increasing device size. We show a proof-of-concept device and demonstrate example applications. These skin buttons can have high touch accuracy and recognizability while being low cost and power-efficient.

 

Piccolo is a low-cost kitset device that uses servos to create a mechanism for tinkering with or developing for basic 2D or 3D CNC output. 

Tim Holcomb, an applications specialist with OMAX Corp., provides a brief overview and demonstration of the company’s new MicroMAX Abrasive Waterjet machine during IMTS 2014.

The editors of MICROmanufacturing magazine have compiled a series of videos focusing on various automated assembly aspects.

Kennametal Inc.'s GOdrillTM addresses drilling operations in a diameter range of 0.0394" to 0.5" in a broad variety of materials and applications, including the production of fuel systems or medical components.

Researchers at the Cockrell School of Engineering at The University of Texas at Austin say they have built the smallest, fastest and longest-running tiny synthetic motor to date. The team’s nanomotor is a step toward developing miniature machines that could one day move through the body to administer insulin for diabetics when needed, or target and treat cancer cells without harming good cells, the researchers said.

 

Precitech and Vision Research, both business units owned by Keene, N.H.-based Ametek Inc., have partnered with Levicron, a German manufacturer of air-bearing spindles, to create a slow-motion video of ultra precision milling.

Mohawk Innovative Technology Inc., Albany, N.Y., demonstrates a micromilling operation at 400,000 rpm with a 300µm carbide tool at a feed rate of 50" per minute.

 

A Stanford researcher has devised a method to wirelessly transfer power through living tissue to charge deeply implanted medical devices, such as pacemakers, in the heart and the brain.

Scientists have invented a method to make a high-powered lens that can transform a smartphone into a high-resolution microscope, according to researchers from the Australian National University (ANU).

Laser expert Dr. Ronald Schaeffer is releasing a series of educational videos titled, “Introduction to Micromanufacturing with Lasers.

In Part I, “Laser Characteristics,” he introduces types of lasers and parameters such as wavelength, pulse duration and pulse repetition rate, among others. He also describes the influence of these parameters on substrate type, feature size and material removal rate.

Leica Microsystems' Leica DCM8 optical surface metrology system is the latest evolution in non-contact 3D optical surface metrology. Designed to help maximize efficiency, the system unites the advantages of HD confocal microscopy and interferometry into one versatile dual-core system.

MAKLab, based in Glasgow, Scotland, hosts a wide range of digital fabrication tools and provides training and entrepreneurial opportunities to 16- to 25-year-olds seeking access to digital technology for their start-up businesses.

Advanced Tool Inc. talks about their trademarked Wear Analysis™ End Mills and a better method to process improvement and cost reduction in CNC Milling applications.

For Microlution Inc., which reports more than 100 micromilling and laser machining platforms installed worldwide, growth has been a constant since its inception in 2005.

Hexagon Metrology's Gary Hobart, the company's national sales manager, demonstrates the Optiv Performance multisensor optical measurement system equipped with a rotary table and a chromatic white-light sensor.

The miniature zinc die-casting process is described in this video from the Chicago White Metal Casting Co., Bensenville, Ill.

 

Laser frequency combs are high-precision tools for measuring different colors of light in an ever-growing range of applications such as advanced atomic clocks, medical diagnostics and astronomy—are not only getting smaller but also much easier to make.
