It can be shortened to G0 as the older machines didn’t have much RAM and every bit counts. This command is used when the tool is not touching the part to rapid move, normally used when going home for a tool change and returning with a new tool. Some machinists like to rapid as close to the part as possible but I advise giving yourself at least 1mm ...
A G01 command is used when you are cutting in a straight line.This command has to have a feed rate (F) active before it will run.A typical block would look like G01 X-100 F50.0;You don’t need to add this command on every line, as long as there is no other movement G-Code active, for example, you only need to add it after a G02, G03 or a G00 command...
G02 is used to machine an arc or radius in a clockwise direction and G03 is for anti clockwise. Using an ‘R’ value to define the radius, the G02/G03 command moves the cutter in a straight line with the defined radius at the end of this move. If a feed rate is already active there is no need to add it to this line unless you wish to change the feed ...
Sometimes we need to pause the cutter for a brief moment, for that we add a dwell to the code to stop the machine from continuing reading the program for a specified amount of time. Uses: While drilling with a flat bottom drill and the surface of the bore has a chattered finish, we can stop moving the drill in Z-Axis with it still rotating for half...
G20 and G21 Imperial and Metric systemsG20 Define Inch units;G21 Define Metric units;CNC Machines can read measurements in both Imperial and Metric systems (inches and mm) this is defined by G20 and G21. Although it is only needed once in the program it is good practice to add this information after every tool change. This makes it safer to run fro...
G90 = Absolute positioning G91 = Incremental positioning A positioning system must be defined before any movements are made, below is an explaination of both positioning systems G90 selects the absolute positioning system. In this mode, all movements of the spindle are taken from the datum position. For example, if X100.0 is read by the control the...
G40 = Cancels cutter compensation G41 = Left cutter compensation G42 = Right cutter compensation Without using cutter compensation when programming we would have to allow for the diameter of the tool when writing the cutting paths. We can program to the dimensions of the component by using cutter compensation. This offsets the cutter by its radius ...
G70 = Finishing Cycle G71 = OD/ID Roughing Cycle G72 = Rough facing cycle G73 = Pattern repeating cycle G74 = Face grooving cycle G75 = Grooving cycle G76 = Screw thread cutting cycle Multiple repetitive cycles enable the programmer to remove a lot of material with just a few lines of g-code, often reusing the profile as a subroutine. These repetit...
G80 = Cycle G81 = Drilling Cycle G82 = Counter Bore Cycle G83 = Peck Drilling Cycle G84 = Rigid Tapping Cycle G85 = Boring Cycle (bore in, bore out) G86 = Boring Cycle (bore in, rapid out) Canned cycles enable us to write g-code to drill and bore many holes with minimum lines of g-code. They allow us to give all the information on a single line, th...
This web page explains the most common G Codes used to control CNC machines, such as rapid travel, linear interpolation, circular interpolation, dwell, and measurement systems. It also shows examples of how to use G Codes to machine different shapes and dimensions on CNC lathes, milling machines, routers, and 3D printers.
