Here’s a complete guide to CNC G-Code for you, a beginner in machine engineering. G-code is a compilation of commands to control movement, speed, and cutting direction. To understand it, we provide a complete table of G-codes for CNC machines that can assist you!
What is G-Code Blocks?
G Code Blocks represent a series of commands in the G-code language aimed at executing specific functions. In CNC machine programming, these sequences are organized sequentially. Subsequently, the CNC machine reads this program sequentially and executes the commands in the G Blocks.

G-code Blocks are recognized by individuals as fundamental elements. Here’s an example of G-code Blocks:
G01 X1 Y1 F20 T01 M03 S500
This single line of function sequence provides a series of instructions to the machine:
- G01: Perform Linear Feed Movement
- X1/Y1: Move from X and Y Coordinates
- F20: Move at Speed 20
- T01: Use Tool 1 for Work
- M03: Turn on the Spindle
- S500: Set Spindle Speed to 500

Using G-Code in CNC Machines
The primary purpose of utilizing the G-code programming language is to produce workpieces as efficiently as possible. Typically, CNC Machine operators follow a series of steps:
- Start the CNC Program
- Select the required tool
- Turn on the spindle
- Turn on the coolant
- Move to a position above the workpiece
- Start the machining process
- Turn off the coolant flow
- Turn off the spindle
- End the CNC program
This flow is a simple sequence commonly adopted by CNC operators and repeats steps 2 to 9. Additionally, to repeat movements on your spindle, you only need to use M03 to turn on the spindle and M05 to turn off the spindle. As an example, in the following block:
CNC G-Code for Beginner
Trough time CNC is evolving but the G-Code CNC Brief is the fundamental thing you need to know. Hence, we write it down for you :
| G0 – Rapid Move | Move the machine axes one by one at the specified coordinates |
| G1 – Straight L | Move in a straight line to a coordinate position at a predetermined speed. For example : G1 X1 Y1 F32. This means that the machine will move straight at coordinates X1 to Y1 with speed of 32. |
| G2. G3 | Clockwise and counterclockwise arcs |
| G17, G18, G19 | Indicating which surface will be used to process the arc. |
| G40, G41, G42 | Define cutting tool diameter compensation |
| G43 | Tool length compensation using Z-Axis Height |
| G54 | Defines a device offset that determines the distance from coordinates |
