How To Machine Magnesium?

The main concern in machining magnesium alloy is the danger of fire ignition when dry cutting. Fire may occur when the melting point of the alloy (400-600 degrees Celsius) is exceeded during machining.

Magnesium has been used in manufacturing notebook computer frames, video cameras, digital cameras, PDAs and other consumer electronics products because of its high strength to weight ratio. When magnesium is alloyed with aluminum, the resultant material is very light and strong, and easily machinable.

The main concern in machining magnesium alloy is the danger of fire ignition when dry cutting. Fire may occur when the melting point of the alloy (400-600 degrees Celsius) is exceeded during machining. The small chips and fine dust generated during cutting are also highly flammable and pose a serious fire risk if not properly handled.

There are several points to note when machining magnesium:

Firstly, use a lower cutting speed when compared to cutting aluminum. The workpiece temperature goes up with an increase in cutting speed and also smaller undeformed chip thickness. In other words, the slower the machining speed and the larger the chips, the lower the workpiece temperature will be. Due to this reason, some companies have modified woodworking tools for machining magnesium so as to achieve larger chips and lower fire hazard.The cutting tools used should have relief and clearance angles that are sufficiently large to prevent unnecessary cutting tool-workpiece friction, thus lowering the heat generated during the cutting process.

Second, keep the machining center clean. Cleaning the machining centers regularly and storing the magnesium chips correctly are important aspects of machining magnesium. Keep a container of cast iron chips near by when machining magnesium, If fire occurs, smother the fire with the cast iron chips.

Thirdly, if coolants are necessary for high speed machining, do not use water-based lubricants. Instead use a light mineral oil, or a water-soluble cutting fluid such as Castrol Hysol MG specially formulated for machining magnesium. Some companies in Japan use semi-dry machining via a misting system.

The fourth point is to monitor the workpiece temperature during machining. Experiments were carried out using thermocouples mounted into the workpiece to monitor the workpiece temperature during machine. Dry cutting of magnesium alloy thin walls was achieved using cutting speed of 440m/min for roughing and 628m/min for fine finishing.

Despite the fire hazards, as competition from overseas low-cost production bases intensifies, and magnesium becomes increasingly used in electronics products, most machining job shops could very well find machining of magnesium a niche worth pursuing.

 

How To Make Lighter and Thinner Magnesium Components?

The most common methods to produce magnesium parts are die casting and thixomolding processes. However, these runner and gating processes provide a low material yield of only 30% for thin-wall casting and can only produce thin walls of between 0.7mm to 1.2mm.

Magnesium is the lightest structural material offering very good damping characteristics, weldability and excellent shielding against electro-magnetic interferance, and is unlimited in supply. It has been an excellent material for making portable electronic and telecommunication devices, and automotive and aerospace equipment such as MD player casings, chassis for cell phones, video cameras and notebook computers, automotive gear housings, car wheels and engine blocks.

The most common methods to produce magnesium parts are die casting and thixomolding processes. However, these runner and gating processes provide a low material yield of only 30% for thin-wall casting and can only produce thin walls of between 0.7mm to 1.2mm.

If we can form magnesium parts from sheet metal just like metal stamping of steel and aluminum parts, we can achieve better material yield of about 80% and possibly safer operation due to the lower processing temperature. However, magnesium is known to be non-formable as it is very resistant to deformation due to its hexagonal close-packed structure. The only way is warm forming of magnesium as deformation of magnesium above 225 degrees Celsius will cause additional slip planes to become operative.

Extensive process research in this area have resulted in a few warm forming hydraulic presses available in the market for draw forming. Recently, research in warm draw forming of magnesium to make cell phone chassis has successfully shown that 0.4mm thin walls can be achieved consistently. Metallographic tests of the chassis have also demonstrated that there is zero porosity and increased rigidity.

While the current warm forming press systems are complicated to operate as they require the preliminary building of stroke and force profiles for the specific products using data acquisition modules and forming simulation softwares, the increased replacement of aluminum and plastics with magnesium for handheld electronic devices may well accelerate this process. Progressive early adopters of this technology would have a first mover advantage in the competitive global manufacturing industry.

 

How To Magnetize Your Desires With Imagination

Everything is spirit. Everything! It is all energy and consciousness.

Using The Imagination To Control Your Thoughts

The imagination is a fascinating, powerful place. For example, remember any incident from elementary school - writing with a fat pencil, perhaps. (Remember those fat pencils?) Now, think of someplace you plan to go in the next month and imagine yourself there. Good. Now, imagine yourself on the moon, looking back at the earth - a big blue marble in the blackness of space. Excellent, isn't it?

This is the power of the imagination: we can return to the past, rehearse the future, and zoom off on flights of fancy - all within seconds.

The images you had may not have been well-detailed, or held in the imagination for very long, but you probably had some sense of each. Some people primarily see in their imaginations, others primarily hear, others primarily feel. Whatever you do is fine.

When you do not have conscience control of the imagination, it is vigorously and creatively used against us. We relive the horrors of the past - the fears that were justified, the guilts that were especially foul, the unworthinesses at their worst, the hurt feelings at their most painful, the anger at its most destructive. Considering the false history created by the mind's careful selection and occasional rewriting, it's easy to feel discouraged about ourselves and everything we might consider doing.

The mind also uses the imagination when considering the future. It projects an image of not just failure but monumental failure, embarrassing failure, public and unconditional failure. Considering this opposition, it's amazing that we even get out of bed. The mind (unless you control it) also uses every news story - and every other fictional account - of disaster to show us why we had better not do anything new, ever. It's time to recapture the imagination from your mind's fears. Your imagination is yours. You can remember the past you choose, rehearse the future you want, and identify with the real and fictional heroes and events of your selection.

When we remember the good things from our past (and all our pasts are filled with both good and bad), we build an image of ourselves as doers and achievers - charmed, kind and terrific. This forms a solid base for future action.

When we project our dreams into a positive future, we see that we can have what we want. A positive image of the future not only shows us how to get there, it draws us to it, attracting us toward our dreams like a magnet.

When we hear some good news, read an inspirational story or see an uplifting movie, we can use our imagination to put ourselves in the center of the action. This allows us to identify with all the good, happy and wonderful images in our culture - and know that we're one of them.
