G Codes and M Codes Explained
Operating CNC machines requires a thorough understanding of programming languages, particularly G codes and M codes, which form the backbone of CNC programming.
These codes instruct the machine to perform specific actions, making them essential for efficient and accurate production.
As you program your CNC machine, you’ll use G codes to specify movements and actions, such as rapid positioning, linear interpolation, and canned cycle operations.
M codes, on the other hand, control machine functions, like spindle rotation, coolant activation, and tool changes.
Here are some key aspects of G codes and M codes to keep in mind:
- G codes define the machine’s motion and action.
- M codes control the machine’s functions and peripherals.
- G codes are usually used in conjunction with M codes.
- Both G codes and M codes are essential for CNC programming.
M46 Functionality and Usage
You use M46 to guarantee a positive move in X and Y axes before a fixed cycle, particularly in Fadal format1 with MC X3.

As you implement M46, it’s essential to understand its specific conditions and applications to avoid misinterpretation and certify proper usage.
M46 Functionality
In Fadal format, M46 sets the stage for a precise approach by guaranteeing a positive move in both X and Y axes before initiating a fixed cycle.
This functionality is essential for uni-directional positioning, canceling any negative moves in both axes before drilling, tapping, or boring a hole.
You’ll typically use M46 in conjunction with M47, which cancels its effects.
Here’s how M46 works in a machine cycle:
- Guarantees a positive move in X and Y axes before a fixed cycle.
- Cancels negative moves in both axes before drilling, tapping, or boring.
- Used for uni-directional positioning in machine tools.
- Typically used in drilling, tapping, and boring cycles, and recommended for individual canned cycle post blocks.
M46 Implementation
Implementing M46 in your CNC code requires a clear understanding of its functionality and usage.
When setting up M46, you’ll need to ponder the specific requirements for uni-directional positioning in Fadal format1 with MC X3. This involves canceling negative moves in both X and Y axes before drilling, tapping, or boring a hole.
To optimize cycle performance, it’s recommended to include M46 language in individual canned cycle post blocks. Be aware that M47 output is necessary in each fixed cycle block, but putting M46 in pdrlcommonb won’t generate M47 output.
M46 Clarification
The M46 command plays a pivotal role in guaranteeing precise uni-directional positioning in Fadal format1 with MC X3, particularly when drilling, tapping, or boring holes.
You might’ve misconceptions about M46, but understanding its functionality and usage is essential for efficient machining.
To clarify, M46:
- Cancels negative moves in X and Y axes before drilling, tapping, or boring holes.
- Guarantees a positive move in both axes before fixed cycles.
