G-codeis a programming language for CNC (Computer Numerical Control) machines. G-code stands for “Geometric Code”. We use this language to tell a machine what to do or how to do something. The G-code commands instruct the machine where to move, how fast to move and what path to follow. In case of a machine tool such as lathe or mill, the cutting to...
At first glance, when you see a G-code file, it might look a quite complicated but it is actually not that hard to be understood. If we take a closer look at the code, we can notice that most of the lines have the same structure. It seems that the “complicated” part of the G-code are all those numbers we see, which are just Cartesian coordinates. L...
So, now as we know how to read a line of G-code, we can take a look at the most important or commonly used G-code commands. We will learn how each of them work through several examples, and by the end of this tutorial we will be able to fully understand how G-code works, how to read, how to modify and even how to write our own G-code.
The G00 command moves the machine at maximum travel speed from a current position to a specified point or the coordinates specified by the command. The machine will move all axis at the same time so they complete the travel simultaneously. This results in a straight line movement to the new position point. The G00 is a non-cutting movement, and its...
The G01 G-code command instructs the machine to move in a straight line at a set feed rate or speed. We specify the end position with the X, Y and Z values, and the speed with the Fvalue. The machine controller calculates (interpolates) the intermediate points to pass through to get that straight line. Although these G-code commands are simple and ...
The G02command tells the machine to move clockwise in a circular pattern. It’s the same concept as the G01 command and it’s used when performing the appropriate machining process. In addition to the end point parameters, here we also need to define the center of rotation, or the distance of the arc start point from the center point of the arc. The ...
Just like the G02, the G03G-code command defines the machine to move in circular pattern. The only difference here is that the motion is counterclockwise. All other features and rules are the same as the G02 command. So, with these three main G-code commands, G01, G02 and G03we can generate a toolpath for, literally, any shape we want. You might be...
The G20 and G21 commands define the G-code units, either inches or millimters. 1. G20 = inches 2. G21 = millimiters We need to note that the units must be set at the beginning of the program. If we don’t specify the units the machine will consider the default set by the previous program.
With these G-code commands we select the working plane of the machine. 1. G17 – XY plane 2. G18 – XZ plane 3. G19 – YZ plane The G17 is default for most CNC machines, but the other two can be also used for achieving specific movements.
The G28 command tells the machine to move the tool to its reference point or home position. In order to avoid collision, we can include an intermediate point with X, Y and Z parameters. The tool will pass through that point before going to the reference point.G28 X## Y## Z## The home position can be defined with the command G28.1 X## Y## Z##.
