  • CNC Machining - Everything before this topic is preparation. CNC Machining is where the rubber meets the road. All the steps of CNC before machining are just preparing for the machining phase of the project. A simple definition of machining is removing material. You remove material in various ways to come up with the part or piece. CNC Machining can be performed on numerous types of material. For example, wood, steel, aluminum, and stone. Machining generally has higher tolerances associated with it. When machining, you are trying to do something more precise. In machining, we use some sort of tool. This tool could be a grinder, drill bit, end mill, router bit or other tool. There are infinite variations of tools. CNC Tooling generally costs a fair amount of money.
  • Design Software For CNC - What I used to do… Before I found design software I was in the stone ages. I would actually hand lay out a template on a piece of paper. Then cut it out. Next, I would tape the design onto a piece of steel and trace around it with a Sharpe Marker. Finally, I would cut out the piece I wanted. No matter what, it was never exact. There would always be something wrong. Things like wavy lines, gouges and “unique parts” were the norm. Measurements were never as exact as I would have liked either. That usually caused some fit-up issues, followed by some grinding. If you know anything about fabrication, grinding is the enemy of your time. Why use Design Software?
  • CNC Control - Since we are dealing with CNC machines that do work for us, we need to control those CNC machines somehow. We need to control them for safety reasons as well. If you give a machine improper commands it can easily get out of control and cause harm to you or the part you are machining. We want to give appropriate commands to our machines, at appropriate times so they are not "out of control". The language that these machines use is called G-code. G-code has been around since the early 60's. There are a number of variations of G-code, but most are very similar to one another. See the previous section for a sample of G-Code. We will need to use a computer to talk with our CNC machine. Our computer will send signals to our CNC machine.
  • Die Cast Products Introduction - Introduction to the Die-Casting Process Die-casting, by definition, is a process in which molten metal is injected into metallic molds under pressure to form objects. The molds, which are generally made of steel and referred to as "dies", can be designed to create very detailed parts with little or no post-machining required after production. Die-casting is similar in many ways to plastic injection molding. Dies can be reused multiple times because the temperatures of the molten metal are not high enough to affect the steel die. Die-cast parts are generally lightweight, and for this reason are often used in aircraft and automobile applications.
  • Iron Casting Information And The Process Of Iron Casting - Iron castings can be referred to as products made out of melted iron molecules. These molecules are, first, poured into mold and allowed to cool. They are then extracted. The casting properties depend a great deal on the foundry practice.
  • Cost Effectiveness Of Using Aluminum Extrusions - Fundamentally, aluminum extrusion is the method of mechanically forcing hot aluminum through a precision-made die in order to produce a particular shape or mold in exact and accurate measurements and shapes in high volumes. Aluminum extrusions are absolutely perfect for a wide range of applications and uses ranging from domestic household use to heavy industries including scientific and aerospace requirements. Aluminum is one of the most versatile elements on the planet and ranks third behind oxygen and silicon as the most plentiful and ranks as one of the most abundant metals on Earth.
  • Diamond not just an allotrope of Carbon - Diamond is an allotrope of carbon. The most important properties of diamond are related to its structure. In diamond, each carbon atom is in sp3 hybridised state and is linked to four other neighbouring carbon atoms held at the corners of a regular tetrahedron by covalent bonds. This results in a very big three dimensional polymeric structure in which C – C distance is 1.54 Ao and bond angle is 109.5o.
  • Pimp Your Ride with Gear Alloy Rims - You've taken the plunge purchased yourself a truck. Well done! Now you'll need your new truck to reflect the vibrant style of its driver, and there are many ways to accomplish this. You can get it repainted, add some new accessories, or perhaps buy new customized rims. You have many options when you are considering which custom wheels to add to your truck. Gear alloy wheels are one popular option.
  • CNC Process Overview - Quick Explanation of the Process This is how I view CNC. I break it down into simple steps that I can remember. Now, they all interact, but it is good to keep them in boxes for simplicity sake. I also like to keep them in a logical, progression type order. Here they are: Design, CAD, CAM, Control and Machine. Today you are going on a journey. You are going to learn about the basics of CNC. I hope you are as excited as I am about this topic. I have been using CNC equipment in my home shop for six years now.

  • G-Code And Experts - Do I need to be a G-Code Expert? In a word, no. You will probably need to know how to quickly scan your G-Code if you are having problems during your machining simulation. Other then that G-Code and a CNC program are throwaway programs for the most part. What do I mean by that? Let me explain. Let’s look at a specific design.
  • G-Codes, M-Codes And Do I Have To Be An Expert On Them? - What is an M-Code? M-Codes are related to G-Codes. M-Codes control different machine functions. Some of these functions are turning the machine on and off. Turning the spindle on or off. Turning a plasma torch on or off. Turning coolant on or off. You get the idea. When programming your CNC machine you may need to perform these functions. Like G-Code, M-Codes vary from manufacturer to manufacturer and from machine to machine. As you can imagine you would need an M-Code for turning a plasma torch on and off on a CNC Plasma Cutting Machine. You wouldn’t need an M-Code to turn a spindle on and off though. Hey, the machine doesn’t even have a spindle. Do I need to be a G-Code Expert? In a word, no. You will probably need to know how to quickly scan your G-Code if you are having problems during your machining simulation.
  • CNC Control Computer - The Control Computer generally resides in the shop somewhere near the CNC machine it is controlling. Control Computers don’t have to be the top of the line, every bell and whistle type of computer. These are the workhorses. Save your money for a good design computer.
  • Home Business - How Do You Choose The Right Home Business Opportunities - It is widely known that today’s job market is being diluted by outsourcing thus creating employment instability. As a result, there are many aged and senior employees finding themselves being replaced and out of their jobs. Some of them may end up wandering around the house doing nothing all day except worrying about what will happen when their savings are depleted. This is one of the negative effects of being retrenched and it is not a good thing for their family. Fortunately, there are a lot of home business opportunities available and they are growing continuously.
  • Ford Racing: Durable Parts - Whether you ride around in an expensive limousine or drive a decades old car that isn't worth a lot, your vehicle's reliability depends on how well you maintain it.

  • Advice on becoming a Carpenter - Carpentry involves a wide range of task from domestic to large commercial projects.
  • Aluminum Extrusion – A Revolution In The Aluminum Industry - Aluminum extrusion - A process by which aluminum is forced into a custom made die and results in a constant cross section that utilizes all the properties of the metal. Aluminum is used in many different industries as it is one of the most versatile and readily available metals on the planet.
  • Die Casting Information, Die Casting Defined, And Types Of Die Casting - Die casting is the method used for forcing molten metal into mold cavities under high pressure. Die casting is very versatile and hence, is the widest used method for casting a metal.
  • High Tech Manufacturing in the United States - As manufacturing seems that it has all but left the United States in search of lower labor rates, there is a large portion that has stayed within the lower 48 states due to high tech manufacturing methods that give U.S. business owners an edge on the competition.
  • Providing a Cleaner Environment With Air Filtration Tools - Air filtration is a process of separating airborne impurities, such as dusts, smokes, gases and fumes using filters, electrostatic cells and absorbents. This process will separate the contaminants from air that can lead to serious health problems. Nowadays, there are many air filtration tool sets that are being introduced for home, industrial and manufacturing use. These are also meant for providing a cleaner environment.
  • Sell More by Expressing Gratitude - Who does not value genuine appreciation? Who does not enjoy a warm smile and a sincere thank you after doing something for someone else. In a sales context, that "something" might be as simple as another person agreeing to meet with you.
  • Automotive Tools For Your Home Garage - You can save hundreds of dollars on garage fees every year by carrying out minor servicing and maintenance jobs on your car yourself. Armed with a selection of widely available automotive tools, a garage manual for your car, and enough time and patience to get a job done properly, pretty much anyone can carry out the routine tasks needed to keep your car on the road and running smoothly.
  • The Sharper Knife: Forged Knives vs. Stamped Knives - We all agree. If a knife isn't sharp, what's the use, right? The sharpness of the blade will make all the difference in the world. And sharpness is largely dependant upon the quality of the blade material from which the knife is made. You'll need to determine whether or not to get a forged knife or a stamped knife. Let's make it clear. Stamped Knives. Stamped knives are stamped out of, or cut from, sheets of metal using a template of predetermined size and shape. This process is called precision machining.
  • What I Know And Remember About Baseball - Bat Selection - It would be nice that there was one equation to decide for each of us what the perfect baseball bat would be. A formula that takes into consideration the basic statistics of height, age, skill level and strength. Fortunately we are all unique, my hand is similar but not exact to your hand. The power in my grip is better than some and worse than others. If everyone who played baseball was batting 750 or better, the game just would not be the heart wrenching, nail biting experience that it is. Little League baseball, College or Professional, the perfect baseball bat is a personal decision based upon experience.
  • The Key To A Great Finish Is Surface Preparation - No matter what your current woodworking project may be, whether it is a built-in bookshelf or a simple jewelry box, to create a truly beautiful piece you must put on a proper finish. To create that lovely finish, it is necessary to prepare the surface properly. This doesn't mean you need to spend a large amount of time preparing it, however. You should divide surface preparation into three distinct stages for the most efficiency. Each stage will use different tools and methods of preparation. In the first and second stages, you will use abrasive tools like planes, scrapers and sandpaper. In the third stage, you will be using fillers and wood putty.
  • The Church Chairs Evolution - Church chairs are one of the most important pieces in Church furniture. Today, you will find a variety of designs for a church chair although this was not really the case in the 17th century. Most of the churches as well as cathedrals prior to 1860 had chapel chairs or church pews in the apse.
  • Laser Welding Ins And Outs You Don't Know - Laser welding plastics is a fairly new process. It super heats the polymer without physical contact. Most applications processes are done by, directing the beam of infrared light. Directly at the weld joint. This is done by going through one of the parts. Commonly referred to as, through transmission. By directing infrared beam of infrared light at the weld joint via( a laser)welding. This technique, the infrared beam, usually a laser, irradiates the joint through a part and the light is absorbed at the surface of the other. While broad band infrared beams can be used, the monochromatic lasers allow very fast heating of small areas of the part that allows the parts to be welded very rapidly, but with very small changes to the geometry part.
  • How a Blog Can Help Your Business - If you have a business, a blog (short for web log) is a marketing tool that can further position you as the expert in your industry. Your prospects and clients want information about your products and services. They are hungry for it! And a blog gives you the opportunity to share your expertise with people across the globe. Once they are set up, blogs are easy to update.
  • “Smart Sourcing” In the Global Environment - Global sourcing is a procurement strategy aimed at exploiting global efficiencies in production, and a standard step in the global expansion of firms.
