Learn About CNC And NC Machining - Free WebTutorial

With Mechanical Engineering background, you know how NC technology is used in every manufacturing industry and the role of CNC machines.

If you don't remember those still,no problem. Lets brush up our brain now.. Here we go..

CNC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders. The CNC in CNC Machining stands for Computer Numerical Control.
On the surface, it may look like a normal PC controls the machines, but the computer's unique software and control console are what really sets the system apart for use in CNC machining.
Under CNC Machining, machine tools function through numerical control. A computer program is customized for an object and the machines are programmed with CNC machining language (called G-code) that essentially controls all features like feed rate, coordination, location and speeds. With CNC machining, the computer can control exact positioning and velocity. CNC machining is used in manufacturing both metal and plastic parts.

First a CAD drawing is created (either 2D or 3D), and then a code is created that the CNC machine will understand. The program is loaded and finally an operator runs a test of the program to ensure there are no problems. This trial run is referred to as "cutting air" and it is an important step because any mistake with speed and tool position could result in a scraped part or a damaged machine.
Well this is one of the video from organized by Ivan irons. This video help you to learn in and out of CNC programming, help you to learn all sort of coding's and troubleshooting.

Here is the first video in the Learn CNC Basics E-Course from This video outline what the e-course is and what it covers. The video also talks about the 5 steps to working with CNC. The steps are CNC Design, CAD, CAM, Control and Machining. Every CNC project has these steps and they must be followed in that order. This gives the beginner a basic framework to hang their new CNC Information on. As the beginner learn they can think about these 5 steps and where the new information fits. The next video in the E-Course is CNC Design.
