Wire EDM and the "Heat Affected Zone" Business Articles | October 18
, 2005
In Wire Electrical Discharge Machining (Wire EDM), the process of tooling by using electricity to cut the materials, there is an area that is known as the Heat Affected Zone. What this means is that wherever the electrical wire passes to make the cut, heat is a generated by-product of the electrical cut. The area where the cut is made is known as the heat affected zone.


Within this heat affected zone, recast, a negative by-product of this cutting and subsequent heat, can be observed. Essentially
, recast is the small amount of melted metal that is produced by the cutting. Several factors decide just how much recast is formed: the amount of power, the type of power used (be it AC or DC power) and the number of passes or skims made to complete the cut. Certainly, more slag or discarded material is created depending upon the electrical current and higher temperatures along with deeper cuts.


The negative side effect of having larger wire EDM heat affected zones and more recast is that the machined object has the potential for a loss of precision due to the recast created in the heat affected zone. There is also a potential for scarring of material along with visual imperfections in the final product.


Older wire EDM machines had less precise electrical charges and varying diameters of wires, which decreased the tolerances and increased the wire EDM heat affected zone, thereby producing more recast.


However, with the evolution and advancement of modern-day wire EDM machines, plants are better capable of decreasing the variance of electrical charge and of using better wires for cutting. With less varying electrical charges
, more precise wires and better passes, and with machining being performed in tubs of fluid, the temperatures are kept at lower and more even levels. All this in turn allows for a more precise cut with less recast created which turns out a much more desirable product. Many shops, after implementing new methods and modern equipment do not even produce recast material.

I remember a football game from last season when the Philadelphia Eagles were hosting the Carolina Panthers. One of the announcers said something like this: "If this game is about passion, it's about Deuce Staley! If it's about passion
, he will be the last guy standing. No one puts more heart and soul into this game."


What will people say about your work, your life and how you play your game? How will they hear your voice?


ESI teaches that passion is the most important ingredient for successful communicators. With passion, you don't need to know all the rules. Without passion, the message may just have no heat, no attraction to an audience of one or one thousand. That is not to say that a passion-filled person is assured success. It is to say that without this powerful ingredient, the presenter will most often fall short.


Passion has many descriptions: hot, determined
, overwhelming. And so on. We remind you however that passion can be expressed in a whisper, from a pillow. We all know the example of a child who wants or needs something important to them can win over the crustiest of adults. Passion.


When John Wesley, founder of the Methodist Church was asked how he attracted such huge crowds to his sermons, he replied, "I simply set John Wesley on fire, and the people come to see John Wesley burn!"


Start your game today with passion. It is hard to resist!

We have all seen people who walk around with great self esteem. It seems that they get all the great jobs, they have the most fun
, they have no financial worries, and their relationships are always top-notch. Now, you may think that their self esteem is a result of all of that good luck, but the opposite is actually true. They learned how to improve self esteem and their good fortune was the result.

Why Donít You Know How to Improve Self Esteem?

In some cultures it is perfectly acceptable to look at oneself and beam with pride, but not in our culture. If you are shy to look in the mirror, you donít like to brag about your accomplishments, and you like to sit in the back of any room
, then chances are your self esteem is in the dumps.

Having high self esteem does not mean that you are cocky. It only means that you have confidence in your abilities, in yourself as a person, and that you are looking forward to even more success.

Watch What Others Do

If you surround yourself with people with low self esteem, then you will be more prone to pick up their habits. But if you start to hang out with people who you see as ďaboveĒ you in some sense, whether it is because they have a better job, more money, a fitter body
, or whatever, you will see the way that they think. They have an aspect to their personality that has brought all of that to them.

Where Can You Get More Information?

There has been a lot of study done in the field of self esteem, and if you are interested in learning how to improve self esteem, then you can obviously buy a book on it or you can look online. There are some very good resources, ebooks, and groups for people who are trying to better their lives by changing the way that they feel about themselves.

When you start to talk to other people, you will see that you arenít alone in this problem
, and whether it is the way you were brought up or your current financial, fitness, or career situation that has destroyed your self esteem, it is never too late to change it. Learning how to change the way you feel about yourself and how to improve self esteem may be one of the best things you ever do.<.
