A Handy Info on Aerial Mapping

Posted on by

Life is literally soaring high with the birth of aerial mapping. Aerial mapping is a system used for collecting information through the use of remote sensing devices or aerial photography, the procedure is done with the help of balloons, kites, planes, and satellites.

Just recently, technology has brought us something even better with the coming of orthophotography. This is a kind of aerial photography specially made to suit the curvature of the planet. In layman’s terms, it’s putting a round subject to a flat surface.

While some do aerial mapping out of sheer curiosity and fun, the maps and surveys are very handy in real estate and wildlife tracking. These maps are employed in wide ranges of driving direction applications and online mapping like Google Earth, MapQuest, Google Maps, and a lot more. There’s Geographic Information Systems that utilized sophisticated maps captured from air imagery through satellites. GIS offers data on terrains and land features from across the globe. The images are given in both coloured and black and white to highlight certain features depending on the application. Nowadays, there are thousands of GIS aerial maps utilized for people’s consumptions.

The importance of aerial mapping is something that cannot be overlooked by land surveyors. Because of the sophisticated tools presented to us these days, many land surveying applications also find the need to require a more detailed image of lands and areas. But while most aerial mapping is used through satellite imagery, land surveyors would normally use helicopter and airplane to get their jobs done.

The reason why aerial mapping is a better choice when taking aerial photos is its high-quality output and the safety it provides to the person taking the shot. After all, the person is not required to step into the actual terrain to capture images. Aerial mapping is very advantageous among situations needing the assessments of dangerous terrains especially among steep slopes, mountain sides, and more.

What is interesting is that there is no institute that guide aerial mapping as a subject. The good news however is there are many means of learning that anyone who would like to pursue this area can make use of. Depending on the field you wish to pay attention to, the job of aerial mapping can be categorized into three parts: the pilot who takes a helicopter up in the air, a photographer who likes to take aerial pictures that will be used for maps, or a cartographer who wish to decode some aerial photos into maps.

There are certain necessities that should be considered if you like to look into your chance of landing a career in the field of aerial mappings. With technology having a great role in this field, one consideration is that you should have a background or a degree in computer science. Most degree programs can run up to 2 or 3 years. You will find loads of colleges and universities that provide cartography education and it is also given as an add-on subject on courses like architectural engineering and civil engineering. It pays to gear yourself with the right learning first so you can become successful in this field of work.

Steps To Drill Stainless Steel Sheets

Posted on by

Stainless steel have a tendency to “work-harden”, due to which drilling such metallic sheets gets very difficult. This normally happens while either cutting or drilling or bending the metal, the heat that is generated hardens it. Usually heat generated while drilling causes the steel sheets to harden faster than any other type of metal work.

There are ways to drill stainless steel sheets, especially those which have been work-hardened. With the help of controlled buildup of heat and using proper drill bit that is designed to be used on harder metals, the drilling work can get quite easy. Here are the steps to drill hardened metal sheets:

  1. First of all, choose a cobalt drill bit that matches the required hole size in the chuck of a drill motor.
  2. Next would be to coat the surface of stainless steel sheets and the tip or the end of the drill machine with cutting fluid. This fluid is a kind of lubricant that is primarily used for machine processes and metal work.
  3. The most important step is how to run the drill motor effectively. Set the end of the drill bit on the surface of the metallic sheet and push it firmly. Then push the trigger of the machine to slowly turn the drill bit. However, ensure that there is no smoke coming out from the drilling area. In case you see smoke then apply further cutting fluid to the area. After the process is over, lighten the pressure from the machine and slowly remove the drill bit from the surface of the steel sheets.
  4. Then apply the same cutting fluid to the tip of countersink drill bit which needs to be attached to the drill motor. Put the tip into the drilled hole and quickly tap the trigger of the drill machine to clear the bur around the edge of the hole.
  5. Finally, wipe off the cutting fluid from the surface of the sheet.

Stainless steel sheets are used extensively in a number of industries.

How Capacitors Work

Posted on by

Capacitors, which were previously known as condensers, are electrical components that store electric charge temporarily. Although capacitors may come in various shapes and sizes, they all have one function in common, storing electrical charge. The capacitor has two terminals that are separated by a non-conducting substance called dielectric. The dielectric can be made of film, paper plastic or air whereas the terminals can be made of aluminum or other conductive metals. One can even make capacitors at home by using two pieces of aluminum foil and a piece of paper. Although it would not be a good capacitor, it would still be able to function.

Although any non-conductive material can be classified as dielectric, only specific materials are used to construct capacitors depending how it will be applied. The dielectric can dictate what type of capacitor it would be and its application. The type and size of the dielectric used would determine the application of the capacitor. Some capacitors may be ideal for high frequency applications whereas others may be better at high voltage applications. They can be used for a variety of applications ranging from torch lights to huge capacitors that can power buses.

Capacitors that use air as a dielectric material in them can be used for radio tuning circuits. Capacitors using Mylar can be commonly found in timer circuits such as alarm clocks and glass and are often used as a dielectric material in capacitors that require high voltage applications. Applications that have high frequency such as x-ray or MRI make use of ceramic capacitors.

The amount of charge that a capacitor can store, which can also be called its capacitance, is measured in units called farads. A capacitor unlike a battery can take only a fraction of a second to completely discharge. A battery may however take minutes to do so. Due to this feature of capacitors, they are often used in the electronic flash on cameras. When you click a picture the flash come and goes off immediately. This is a good example of a capacitor discharging all its stored energy in a fraction of a second. When the flash is not clicked, the battery charges it up and it discharges this energy when a picture is clicked using flash. This however can be dangerous as capacitors such as those in television sets can contain large amount of charge. Therefore, if you were to open your TV set and touch the fully charged capacitor it could kill you.

Capacitors have definitely improved electronic devices tremendously and as well as aided in the advancement of technology greatly. However, when using electronic devices that have capacitors that can store a huge charge, one should always be very careful.

Magnetic Workholding: Faster Setup and Improved Productivity

Posted on by

If reduced setup times and increased productivity are critical to your operational success, then you should consider making the change to magnetic workholdings.

Magnetic workholding overcomes many of the intrinsic problems associated with the manual clamping of components by multiple vises, toe clamps, strap clamps or other forms of tactile workholding. But the benefits extend well beyond the shop floor where ease of use and quick changeovers rule the workday. Improved ROI and productivity are two bottom-line benefits this type of workholding solution.

Magnetic Workholding Essentials

Workholding magnets are an alternative to mechanically holding work-pieces in machining operations. They are constructed of a series of magnetic poles, pods, set up blocks, pole extenders, or modules. As more pole pieces make contact with a work-piece, a stronger magnetic clamping force results. They are controlled in such a way that clamping power is both uniform and instantaneous.

These workholders use either permanent or electro-permanent magnets. The permanent magnet workholder does not require power while the electro-permanent magnet uses power in order to energize the magnet via an electronic control. This electric power is only used during start up, so a continuous supply of electricity is unnecessary, hence, power outages or brownouts are never a safety issue. Depending upon the application, workholders using magnets can exert a uniform and instantaneous clamping force of 12 tons per square foot. Recent advances in magnetic materials have increased their clamping power while reducing their footprint.

Magnetic Workholding on the Shop Floor

Reduced setup times and faster changeovers are two benefits that this type of workholding brings to the shop floor. Unlike mechanical clamping that requires adjustment, there’s no need to adjust the workholders so time is saved. But the benefits do not stop there.

Vibration reduction is a complementary benefit. Since the magnetic clamping force is instantaneous and uniform, vibrations are minimized. With less vibration, work-pieces are machined with greater precision, more repeatability, less scrap or rework, and less deformation of cutting tools.

Operational and Economic Benefits

Because of their intrinsic benefits, magnetic workholders are a boon to productivity. Fifty percent reduction in setup time has been attributed to this type of workholding in some instances. Cycle time improvements from less vibration and uniform holding force are added benefits causing an extension of tool life and spindle up-time. These benefits translate to better profit margins and ROI paybacks in record time. The technology of practical magnetic workholding is in place now.

Advantages of Buying a New Forklift Truck

Posted on by

For any business that requires a forklift truck to facilitate day to day operations, there may come a time when consideration is given to the purchase of a machine. This is a decision that should not be taken lightly, and one must consider carefully the requirements of the business, the application of the truck and the number of hours it will be required to work.

Purchasing a new forklift truck is a big decision for any business, but it is one that delivers a number of key advantages. The first is that buying new allows one to purchase a machine to the exact specifications required for the application. Therefore it is advantageous to provide your dealer with the specifications you require, such as load to be lifted, the lifting height required and the environment the truck will be utilised in. Some dealers may require you to fill out such as form, but it is always worth asking for a demonstration of the machine identified as best for your needs to further ensure suitability. Buying a new forklift truck can allow one’s exact specifications to be met absolutely which might be harder if looking for such specifics in the used market.

Another advantage of buying new is improved reliability and absolute knowledge of the truck to be purchased. In addition purchasing a new machine, means one can take advantage of longer warranty terms, and avoid the element of the unknown with regards to the history or previous treatment of a truck, which can be the case with used materials handling equipment.

New forklift trucks also offer the buyer the latest technological advances, for example Hyundai forklift trucks offer increased mast tilting angles, between 6 degrees forward and 10 degrees backward, providing the operator with a safe and rapid platform for loading and unloading. The same manufacturer also features the latest wet brake disc system. This system features enclosed brakes, protected from dust and water, thus improving brake performance and hence increasing maintenance intervals.

Of course the purchase of a new forklift truck is a big commitment financially but if a machine is to be used for forty hours or more a week, this might be a worthwhile investment if budget allows. It may also be possible to obtain a lease purchase agreement to spread the cost of your purchase. Some new machines may be more affordable than others. It would be side to obtain a range of quotes and make sure you deal only with reputable companies. Searching for official dealers for your chosen forklift truck brand, will help to ensure this.

In summary buying a new forklift truck can initially be an expensive purchase, but in the long run it can be a key asset in improving the productivity of your business. Buying new allows one to obtain a machine that is perfectly tailored to the job it is required for. It also has the advantage of improved reliability and extended warranty terms, although it would be wise to check the latter to check the extent of their coverage.

Metallic Yarns

Posted on by

Metallic Yarn Manufacturing Process

Metallic yarns are by and large made from strips of a synthetic film, such as polyester, coated with metallic particles. In one more method, aluminum foil strips are sandwiched amid layers of film. Metallic yarns may also be made by twisting a strip of metal around a natural or man-made core yarn, producing a metal surface. It is made of thin film and supported by nylon or polyester or rayon yarn according to the type of yarn.

Metallic yarns start as rolls of films or laminations 30″ or wider. These wide rolls are slit into narrow rolls 2″ to 5″ wide. These narrow rolls are gang slit across their whole width to micro widths from 1/128″ (.0078″) and wider and then taken up on plastic spools for shipment to textile mills.

There is a rainbow of colors available from red, blue, green, etc. to gold and silver. Brilliant, reflective colors which add decorative patterns to fabrics.

Metallic Yarn Uses

Metallic yarns are woven, braided, and knit into many fashionable fabrics and trims. For added variety, metallic yarns are twisted with other fibers such as wool, nylon, cotton and synthetic blends to construct yarns which add novelty effects to the end cloth or trim. They create all textiles more eye-catching by adding sparkle.

At one time or another, metallic yarns have been used in just about every variety of textiles. Metallic Yarn is used in manufacturing knitting wears, knit & woven fabrics, embroideries, labels etc. Some end uses have been in automotive fabrics, television front fabrics, bath towels and face cloths, clerical vestments, bathing suits, hosiery, upholstery, hat bands, etc. Also in theatrical clothing, theater back drops, doll clothing, banners and uniforms.

Care of Fabrics with Metallic Yarns

Specialized dry cleaning with perchlorethylene is favored to laundering. Hand laundering with Woolite and cold water is the only suggested laundering method. Never launder with bleach. Fabrics containing metallic yarns should be treated like all synthetic fabrics. Ironing should be at the lowest setting on the iron. If there is no thermostat on the iron, do not use that iron. Do not use steam when ironing metallic yarns.
