Laser Glass Cutting

Posted on August 19, 2012 by CapeAdminCraft

Laser cutting is a precision cutting method widely used in industrial manufacturing. Laser cutting allows a level of accuracy unmatched by any other cutting method. A high-powered laser is directed at the material to be cut. the material burns, melts or vaporizes, leaving a high quality finish.

Apart from the common materials such as wood, plastic and metal, laser cutting is also widely used in the processing of glass. Glass has become an important component of a large number of applications. its use is not just restricted to windows and bottles but has expanded to telecommunications and information technology. these modern applications require a higher level of accuracy and precision that cannot be matched by traditional methods.

Traditional glass cutting methods make direct contact with the surface, increasing chances of unwanted scratches and abrasions. Moreover, material losses and glass dust are other problems faced in the conventional process.

The use of lasers has revolutionized the art of glass cutting. the laser beam is used to produce highly complex and accurate shapes with a fine edge finish. the power of the laser beam ranges between 1000 to 2000 watts. Most laser cutters are integrated into an enclosed machine with state-of-the-art software. Since the laser used is a class 4 laser, care is taken to keep the user away from direct contact. the CO2 laser is the most common device used in glass cutting.

The advantages of laser cut glass are many. apart from the superb quality edges, flaking, chipping and micro-cracks are almost completely eliminated. Moreover, laser cut glass is up to 3 times more durable than conventional cut glass. Since cutting oil is not used in the process, the glass washing process is also minimized.

Laser glass cutters can be used to cut glass of any thickness with an equal amount of accuracy. From decorative articles and frames to quartz crystal oscillators and display glasses, the use of these devices is limitless.

17:33 GMT, August 12, 2012 (Released Aug. 7, 2012) Corpus Christi, Texas | nobody works on more Army helicopters than Corpus Christi Army Depot, so when it comes to repair and overhaul, they cut a lot of metal. Gone are the days of hunching over a pristine sheet of metal meticulously drilling holes and patterns by hand. now, depot artisans are a step closer to automating the entire sheet metal manufacturing process at Corpus Christi Army Depot, or CCAD. "this automation will increase quality, reduce manufacturing times and allow one standard time allotted for cutting and deburring patterns and formatting aircraft sheet metal parts manufactured at CCAD," said Roland de la Fuente, a sheet metal mechanic supervisor. their new laser was put into production in 2010, but it went virtually unnoticed next to the bus-sized fluid cell press that normally steals the show. "it takes having to see the laser in action to really get the ‘wow factor,’" said de la Fuente of the new laser cutter. The fixture is described by the manufacturer as a high performance linear motor that delivers high-speed cutting for fast, continuous processing of high quality parts. The laser cutting fixture is used to cut sheet metal patterns that are later formed with the fluid cell flex press or power brakes before they are put on a helicopter. with a cutting speed of 40 meters per minute, the laser is faster than producing patterns by hand. The laser can cut through several thicknesses of different material, including plate steel, stainless steel and aluminum. Patterns are guaranteed to cut within tolerance, with a repetitive accuracy of .0008 ten thousandths of an inch. Aircraft sheet metal mechanic Jeremy Garcia has noticed a big difference in the time it takes to produce parts since they started using the new fixture. "it took us 24 hours to manufacture by hand," he said. "now manufacturing takes only eight hours." in the past, a sizeable product like a UH-60Black Hawk helicopter bulkhead required the part to be pressed by hand in multiple sections. it all changed with the new fixture. The laser cutter can cut a pattern in as little as five minutes. "It’s one run and that’s it," said Garcia. The advantage of the new laser comes with the computer technology. The laser is controlled using a computer and CADMAN software. The CADMAN is a computer-aided drafting program that specifies the laser’s cutting path. "The laser is the first member of a fabrication cell I am developing to support the fluid flex cell," said de la Fuente. Plans for another laser, a turrent punch and two power breaks, all using the same CADMAN software, are in the works. by utilizing the same CADMAN software, all the machines will be able to community with each other. according to LVD, the CADMAN programming software offers offline integration of the key sheet metalworking processes of laser, punching and bending. "this will allow the artisans to create pattern-cutting and forming programs at the instant the flat patterns is drafted in CADMAN," said de la Fuente. "The artisan can then transfer the pattern-cutting program to a punch or laser or even transfer a brake-forming program to the power brakes without having to leave his seat." "The laser has performed superbly thus far," he said. The laser cutting fixture and the subsequent automation implementations will allow CCAD to schedule accurately and allow the training of a more technologically-proficient workforce to meet unpredicted surges in demand. —- Brigitte Rox, U.S. Army

Laser Knife Concept Allows For Cutting Of ‘Foodstuff’ [Video]

Posted on August 18, 2012 by CapeAdminCraft

Posted: August 13, 2012

Cutting food with a sharp knife is an age old practice that could get a big boost thanks to one enterprising designer at this years James Dyson Awards.

Andrey Kokorin submitted a conceptual design to the young designers competition which places food inside a spherical pod and then cuts that food into segments selected by the user.

Kokorin says he submitted the concept because he wanted to get rid of unsanitary kitchen knives which often carry diseases.

The new “knife” is called the “Innovative Laser Device for Cutting of Foodstuff,” and it uses a set of rotating rings that are lined with electromagnets which following the directions of internal microprocessors to cut food into slices as small as one-millimeter.

The device would use mass or simple images to determine the cutting pattern of each piece of food placed inside of the device. Users would also be able to browse a menu of items from a display screen, allowing them to find optimal cutting patterns for their fruits, vegetables, and other foodstuff.

The young designer hopes to create a “smart” kitchen in which everything can be easily cleaned and stored away for later use.

Here’s a video showing off the foodstuff laser knife. Pay close attention to the removable food holder and revolving laser blade design:

I personally like the idea of a silent knife that keeps my fingers away from sharp edges. I don’t mind cutting food but having a gadget that cuts for me seems like the next logical step in food preparation.

Optical Product Manufacturer Improves Production Quality and Expands Service Offering with New Waterjet Cutting Machine

Posted on August 18, 2012 by CapeAdminCraft

American Polarizers inc. has announced the acquisition of a precision waterjet cutting machine to be used in the fabrication of the company's polarizing glass filters and other light filtering/polarizing products. API will now offer waterjet optical glass cutting services in addition to film and plastic laser cutting. Configured especially for cutting optical glass, API's waterjet cutting service leaves a chip-free finish with smooth edges so that no grinding is needed which saves time and helps reduce production costs.

Reading, PA (PRWEB) August 02, 2012

American Polarizers inc. (API), a world leader in the manufacture of polarized filters and other optical products, has announced the acquisition of a precision waterjet cutting machine to be used in the fabrication of the company's polarizing glass filters and other light filtering/polarizing products. Additionally, API will now offer waterjet optical glass cutting services in addition to film and plastic laser cutting.

Waterjet cutting is accomplished using a very thin stream of water. This enables high precision cutting and facilitates speed and accuracy on intricate shapes and details, tight radial corners and piercings. because the water stream is so fine, there is very little loss of material which is an added benefit when cutting high-end optical glass. the software used with API's new machine makes it possible to cut virtually any shape that can be conceived and drawn into the program.

"We've used laser cutting equipment for years," said API sales manager, Les Fasnacht, "and lasers are excellent for plastics and films. but for cutting glass and glass laminates, we've found the waterjet provides the smoother cut and superior edge quality which we and our customers require."

Typically, waterjet cutting operations are set-up for rapid cutting of a wide range of materials such as steel, aluminum, composites, glass and others. This approach often yields acceptable results for some materials but gives sub-optimal quality and even chipped edges on glass substrates. Chips can adversely affect the way light is refracted and reflected, and chips can also propagate and cause a fracture.

Configured especially for cutting optical glass, API's waterjet cutting service leaves a chip-free finish with smooth edges so that no grinding is needed. the elimination of the need for secondary finishing processes saves time and helps reduce production costs. Additionally, waterjet cutting does not generate any heat build up resulting in zero change in material properties.

Previously, said Fasnacht, API had to farm out special glass cuts. He explained, however, that with the specialized use of the waterjet, API has increased cutting precision and detail capability. "And since the machine is in house," said Fasnacht, "we have improved our turnaround times. Not only can we offer a better product in less time, but we can also provide the same precision cutting services to anyone with optical material cutting requirements."

Post Laser Cut Checkfit

Posted on August 17, 2012 by CapeAdminCraft

The first laser cutting for Grisbot went smoothly and the blue acrylic is beautiful. now let’s do a checkfit as the Sketchup design encounters the physical world.

Here are the pieces snapped together:

No problem here. The pieces come together just like a puzzle!

Now let’s tighten the bolts:

You’ll have to take my word for now, but it’s all very snug and there’s no jiggling of the frame once the nuts are finger-tight.

As you can see in the following two photos, battery and breadboard have more than enough room:

(Bolts were inverted for these checks, of course.)

Now a look at the ball caster:

Here we have a problem. My Sketchup model of the caster didn’t have the diamond-shaped base and I’m paying for it. The bottom piece of the robot casing will have to be extended back (ie, to the right in the photo) at least an eighth of an inch so that the bolt holes will align, and maybe add another eighth inch so that the ledge fully covers the base.

Now it’s time to check the servo fit, which is likely to have problems because the servo model I downloaded from Sketchup Warehouse turned out to not have the right dimensions and so I had to make my own servo model based on personal eyeball measurements.

Alas, to obtain the servos, I have to ‘cannibalize’ my beloved Grisbot Prototype #1, so here is a loving last picture:

And now we checkfit the servo, and . . .

SNAP! not good. The fit was so tight that one of the acrylic sides broke as I tried to force the servo into position. Maybe a sixteenth of an inch horizontal and vertical widening will reconcile the fit, and I think I’ll have to give a closer look to the bolt hole alignment too.

So, in summary, there are three checkfit fails: the caster and the two servos. to accomodate, I’ll redesign the bottom and side pieces and then it’s back to the laser cutter tomorrow. Results will come on Thursday.

Move Over, Lasers: Masers Now Work at Room Temperature

Posted on August 17, 2012 by CapeAdminCraft

The core of the new room-temperature maser

When the laser was first invented, it was “a solution waiting for a problem,” a piece of cutting-edge technology with no applications. Today, found in everything from sensors to communications to surgery, the laser has come into its own—but it may be time to step aside and share the spotlight with its older brother, the maser.

Lasers and masers work on the same principle, amplifying light through a process called stimulated emission, except that lasers amplify visible light while masers act on microwaves. Light and microwaves are both forms of electromagnetic radiation, but microwaves have a wavelength 100,000 times greater than that of visible light. but although the maser has been used for deep-space communications and atomic clocks, lasers have always outshone their predecessors. And masers have only themselves to blame, as these finicky devices require extreme conditions like vacuum or cold temperatures. now, however, researchers have finally produced a maser that functions while surrounded by air at room temperature.

While the room-temperature maser is currently a solution with few applications, it may rise to prominence for its amplifying ability. Amplifiers are a vital component in any electronic circuit. The lower their noise, the better amplifiers perform—and masers have very little noise. There’s just one flaw keeping room-temperature masers out of everything from your GPS receiver to your smartphone: the current incarnation of the room-temperature maser, still in the early days of its development, is a power-hungry device the size of a coffee cup.

“The crucial thing to point out is that this device has in no way been optimized,” says the study’s lead author, mark Oxborrow. “Nobody really knows what the limits are. That’s what’s exciting about it.” Early lasers and even transistors were also large and ineffective, but as researchers kept tinkering with them, they gradually shrank down and wound up revolutionizing electronics. with more development, room-temperature masers could improve radio telescopes and medical scanners, and beyond. “Because amplifiers are so fundamental,” Oxborrow explains, “if they can be shrunk down, masers have a good chance of finding applications in many places.”
