In case you didn’t know CNC is an acronym for Computer Numerical Controlled Machine, and these machines have become one of the most popular metal cutting tools currently used in engineering today. With the arrival of computers, the requirement for humans in many engineering processes is becoming less and less. This is particularly evident in […]
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 […]
Building your own 3-Axis CNC router
Building your own 3-Axis CNC router is both fun and educational. This Instructable shows all the steps I followed to make my DIY CNC Router. This is the second one I made, after learning a lot from building the first version. This is a very good router that can be built at a reasonable price […]
CNC Drawing Machine
Hello all and welcome to my first tutorial! Today I am showing you how to design a drawing CNC using as primary Hardware components a Digilent Arty board, DC Motors and RC Servos. Important Note: Because I am currently working on this project I will show you how to build the CNC and how to […]
How to Make a Three Axis CNC Machine (Cheaply and Easily)
The idea behind this Instructable was to fulfill my desire for a desktop sized CNC machine. While it would have been nice to purchase an off the shelf unit the issue of price as well as size proved prohibitive. With this in mind I endeavored to design and build a three axis CNC machine with […]
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 […]
Things to Consider in buying a CNC router
When thinking of buying a CNC router, there are many things to take into consideration. One of the first things to do is take a hard look at what the machine will be expected to do. Too often woodworkers are lured by the technology and buy unnecessary options. Although most router vendors will promote the […]
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 […]
Milling and Machining Center Basics – Stanford University
Milling Machine Types The most basic milling machine is the vertical spindle, ram-type “knee” mill. Though not well adapted to production milling, it is ideal for toolmaking and prototype modeling. Knee mills are primarily used for manual operations, but their capabilities can be expanded. The knee travels vertically, up and down the column and supports […]
