Control CNC – Controlling CNC and you Considering that we are dealing with devices that do work for us, we have to manage those machines somehow. We have to manage them for security reasons too. If you provide a device improper commands it can easily get out of control and trigger damage to you or the part you are machining. We want to offer proper 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 actually been around considering that the early 60's. There are a number of variations of G-code, but many are really just like one another. See the previous section for a sample of G-Code. We will certainly need to make use of a computer system to talk with our CNC device. Our computer will send out signals to our CNC machine. Between our computer system and our CNC machine sits a controller. A controller converts commands into signals that are used to control the motion of our machine. As these signals are sent out of the controller, they go to either stepper or servo motors. This is how we develop motion. These motors drive our various axis on our CNC machine. While we are moving our axis, there is normally a cutting tool of some sort getting rid of material. This is the machining process combined with CNC. Right here is a short description of the two kinds of motors normally utilized in CNC: Stepper motors: Easy design Easy to use Produce torque at low rpm Do not know their position in relation to the program Servo Motors: Produce torque at high RPMs Usually require gearing of some sort to be effective More advanced Can maintain their relative position, therefore, they can be more accurate Machine Controllers
Controllers normally stand alone near the CNC machine. They act as a translator between your control computer and your CNC device. Typically, they putting quite a bit of cost to a CNC machine also. Controllers can cost anywhere from $1000-$20,000 or more depending on their elegance.
