CNC Projects

Having an engraving or a model manufactured through the use of CNC machines is a cool process. We no longer have to make things with our bare hands and can now control the accuracy, timing and repetition of new products through the use of Computer Numerical Controlled (CNC) machines. With that said, knowing the process […]

Commonly Used Bits for CNC Milling Operations

In addition to CNC milling being used for metal objects, it is commonly the preferred choice for woodworking. With this method of operation, there are many times when wood cutting is required but compared to metal fabrication, producing holes takes less pressure. For that reason, drill bits are quite different for the two different types […]

History of CNC Milling

CNC milling is sometimes referred to as CNC machining, which operates using commands or G codes programmed from an internal computer. CNC, the acronym for Computer Numerical Control, consists of alphanumeric codes, each leading to very specific functions performed by a machine. In the 1950s, the Massachusetts Institute of Technology and United States Air Force […]

What is CNC?

CNC is the acronym for Computer Numerical Control. It is an outgrowth of the older term “NC”, which stands for just “Numerical Control”. It refers to the idea of controlling machine tools via computer. CNC Machines are robots of a sort. With the older “NC” term, a computer need not be involved. The machine might […]

How To Build A CNC Machine

I am a regular guy. I do not have a huge fancy CNC machine at work. I do not even have a small milling machine or a lathe. My friends do not have them either, so I have nobody to machine some custom parts for me. I have inquired with several shops and individuals who […]

10 Tips for Growing Your CNC Machining Business

Starting a new business can be a challenging endeavor, especially if the entrepreneur is entering a crowded market with large, well-established competitors already in place. Small CNC machine shops face hurdles similar to those of other small businesses, and, like their non-industrial counterparts, have the same potential for securing contracts and growing within the industry despite […]

Bipolar vs Unipolar stepper motors

There is a lot of discussion on whether to use bipolar or unipolar stepper motors for your CNC project. Each type of motor has different characteristics, but when all is said and done, the best choice is usually bipolar stepper motors. This article is a short explanation why bipolar stepper motors are usually the better […]

Choosing the Right Stepper Motor

Choosing an appropriate stepper motor for your CNC project is important. If you choose a motor that is too small, you may experience very slow maximum speeds and torques, and even missed pulses. On the other hand, if you choose a motor which is too big, it may require a powerful and expensive power supply […]

Choosing the Right Stepper Motor Driver

Choosing the right driver for you stepper motor is important because it will allow you to get the maximum amount of performance out of your motor. There a few types of drivers available, each with their own characteristics. Use a driver with a built-in chopper circuit First and foremost, make sure that whatever driver you […]

How to cut line art with CNC machines

Generating G-Code for line art is a simple process that can be perfected with a little practice and the appropriate software. CNC machines are spectacular for cutting line art, whether you are doing a one-off piece or mass production. Line art can mean anything from actual line art, to simple mechanical components that can be […]
