Advances in Wire EDM Technology

With modern wire EDM machines utilizing CNC (the computer Control, or the brains of the machine if you will) for production, there is a user-interface device, the computer, where the worker will input the required data for design that will eventually guide the wire EDM machine during the passes and cuts in the process of creating the final product. Moreover, like any computer today, software is needed to run the equipment. This is no different in wire EDM. The CNC controller and the software application comprise the wire EDM technology.

In much the same way that many different software applications for word processing or email exist, so to are there numerous wire EDM technology software applications for wire EDM machine CNC controllers, nearly all of which integrate with varying AutoCAD or similar CAD/CAM software. Today, developers can create the object in AutoCAD, designing tensile strength, variances, etc. and provide that to a wire EDM shop that will then plug this design into the wire EDM Technology software, which will in turn drive the machine, turning out the final product.

Some of the more popular wire EDM technology software applications today, which are typically supported on Windows operating system machines, include:

-PEPS wire EDM, developed and distributed by Camtek -VISI-wire, developed and distributed by Vero International software -TracTrix, developed and distributed by Trixsystems

Each wire EDM machine CNC controller will have its own requirements as to what software can be used. However, nearly all software today can incorporate and use files with numerous extensions, e.g. .DWG files from AutoCAD, to decrease the time from development to production. Furthermore, by being able to pull the commands for wire EDM from the developers CAD file, the final product will have no variance from the developers final vision of that product before production.

Buyer's Guide to Microphones

Attaching a microphone to your computer can be both useful and lots of fun - and it could even save you money. With the right software, you could use your microphone for speech recognition (talk instead of type), video teleconferencing and internet telephony (save on those long distance and international calls!).

You can also use your microphone to record sounds (and your voice) and play them back via your computer.

- Microphones can be wireless, or hardwired directly into your PC. wireless can, of course, be more convenient to use. Good quality wireless microphones produce perfectly acceptable results, but they can be more expensive than hardwired microphones.

- Microphones usually connect into the microphone jack in your sound card. Thus, the quality of the recording will depend, to a very large degree, on the quality of your sound card. If you have an old sound card, it might time to think about upgrading to a new sound card.

- Most audio software includes a calibration feature which allows you to adjust the recording levels depending on your microphone and the volume of sound. To ensure the best quality records possible, you should use this feature whenever you switch microphone, and even when you switch between different audio software packages (which may assume different level settings).

- If you want best results, it is very important that you position the microphone correctly. Check the manual for instructions. If necessary, try experimenting with different microphone positions. Don't forget to recalibrate your audio software, if you do reposition the microphone.

Breathing Out Stage Fright

You're stepping onto the stage, amidst opening night flurry and last minute stage directions. In the audience are the director you'd like to work with, the reviewer everyone listens to, and your first acting coach. The blood pumps in your ears, your heart is racing, and your throat is so dry you can't possibly speak your lines. Every muscle is tense and you want to run.

It's called the "fight or flight" response. It's also called stage fright. Stage fright comes in many different forms. For some, it's a nervous energy that disappears as soon as they begin performing, or a familiar sensation that's always under the surface but feels manageable most of the time. For others, it's so debilitating that they can't get through an audition to even be part of a performance.

Stage fright has huge repercussions to the health and well-being of the performer.

Dr. louise Montello of Musicians Wellness, Inc. has worked with injured, blocked and anxious performers for many years, and has developed a rich set of tools that we can use in moments of stress and anxiety.

One of her most powerful techniques, from the Yoga tradition, is breath. Breath is a key link between the mind and the body. Our body's autonomic nervous system is made up of the parasympathetic nervous system (related to relaxation, creativity and awareness) and the sympathetic nervous system (related to analytical thinking and action). When we're in "fight or flight" mode, our sympathetic nervous systems are in charge, and our bodies, minds and emotions are locked into battle with an imaginary enemy (while our creative expression gets caught in the crossfire).

Deep breathing and the specific techniques that will be described in this article can reawaken your parasympathetic nervous system.

Note: In yogic breathing exercises, it's important to always breathe in and out through the nose.

1. Diaphragmatic breathing ("belly breathing")

Why? It allows you to move more air into your body and also to send more stale air out on the exhalation.

How? practice this type of breathing while holding your hands on your belly, to feel it expand as you inhale, and contract as you exhale. Your back and sides should expand and contract as well. Watch a baby sleeping to get a really good demonstration of belly breathing.

2. Even breathing

Why? Will smooth out your breathing and help you to feel grounded.

How? Breathe in and out for the same number of counts.

3. Two-to-one breathing

Why? Since exhalation is associated with the parasympathetic nervous system (related to relaxation, creativity and awareness), long exhalations also help to induce relaxation. This exercise is helpful in times of great stress (i.e. auditions).

How? Breathe in for a certain number of counts, and then breathe out for twice as many counts (count evenly in your own time), pushing the breath out from the belly.

4. Alternate nostril breathing

Why? By alternately breathing through our right nostril (connected to our sympathetic nervous system) and our left nostril (connected to our parasympathetic nervous system), we can balance our entire autonomic nervous system.

How? To prepare for this exercise, clear your nostrils by breathing in and out quickly several times in a row (another technique called "cleansing breath"). Now, fold the index finger and middle finger of the right hand into the palm, and use the thumb to close your right nostril and your ring finger to close your left nostril.

Begin by inhaling through both nostrils. Then breathe out through one nostril, while blocking the other, and then switch and breathe in through the other nostril.

After three complete breaths, exhale without switching sides, and do three more breaths. This means you're now inhaling on the opposite side that you started from.

Now rest and breathe deeply and evenly through both nostrils for a few minutes. Then repeat that cycle two more times (with a rest in between), so you've done three cycles in total.

You'll be amazed at the difference these simple breathing exercises can make, with a few short minutes of practice every day. Then, at times of stress, you'll have a valuable tool to support your performance, and all your creative dreams.
