What Kind Of Code Is Used For CNC Machines?
G-Code is the common name for the programming language of CNC Machines. Somewhat of a generic, catch-all type of term for CNC programming language. Very few machines adhere to this standard today. There are as many varations as there are manufacturers.
This is how I think of G-Code. It is a simple language built off of the Cartesian Coordinate System for motion control. I don't know if that is exactly right but you will get my meaning in a second when we go through some code line by line. You will remember your High School Geometry soon enough. For the real pros out there you know there is much more to G-Code then that, but it is a good place to start.
You will see many variations of the G-Code name like:
Gcode
gcode
G-Code
g-code
G Code
G-Code
Are there other "Codes?"
In a word...Yes. We will get to that in a moment. G-code is also the name of any command in a CNC program that begins with the letter G. G-Codes generally tell the machine to perform an action. G-Codes can tell machine to move a certain distance in the X-Axis for example. Or, make a rapid move to another location. Or, move in an arcing fashion while milling. An on and on and on.
Here are some examples of G-Codes. Remember these change to a certain degree between CAM Software packages and CNC Machine Manufacturers.
·G00 Rapid positioning
·G01 Linear interpolation
·G02 CW circular interpolation
·G03 CCW circular interpolation
·G04 Dwell
·G20 Programming in inches
·G21 Programming in mm
·G28 Return to home position
·G40 Tool radius compensation off
·G41 Tool radius compensation left
·G42 Tool radius compensation right
·G43 Tool offset compensation positive
·G44 Tool offset compensation negative
Why does G-Code Change?
We humans like flexibility. We also like standards. G-Codes are standardized in a certain sense. Once you start to be able to read it, you can read just about any flavor of it. That is the standardized part.
All machines are not created alike though. Even identical machines are different to a certain degree. They may not have the same tools loaded or they have been slightly modified to produce a certain type of part. Interesting how people like to customize.
That is why G-Codes are not the same. You need some flexibility in the programming to accommodate all situations. Couple that with every manufacture thinks their version is the best and you get a myriad of G-Codes out there.
Many manufacturers also try to force you to only use their code. For example, they give you a design interface to make parts and a CAM interface to produce code. They lock you into their "Black Box" so you can't go elsewhere for service and support. They lock you in their "Family." Sometimes they make up a whole different kind of G-Code language that no one can understand but them to keep you hand tied up.
