This guide will explain everything you need to know about this unit mode command—what it is, when to use it, and why it matters.
(Step-by-step.)
Key Takeaways
- M91 CNC code overrides dynamic feedrate adjustment during cutting operations in Mitsubishi FX10 machines, ensuring precise control over the cutting process.
- It fixes feedrates for positioning moves, such as rapid movements, and is essential in wire EDM machines for cutting difficult materials.
- M91 is a machine-specific code, and its compatibility should be checked before use to avoid inefficient machining operations.
- It is used for adaptive cutting control, enabling adjustment of cutting parameters in real-time, and is distinct from M90 adaptive feedrate control.
- Integrating M91 into g-code releases its full capabilities, allowing fine-tuning of cutting parameters and optimized code performance.
Understanding M91 CNC Code
When working with Mitsubishi FX10 machines, you’ll likely encounter M91 CNC code, which plays a crucial role in overriding dynamic feedrate adjustment during cutting operations.
This code is essential in industrial machining applications, particularly in wire EDM machines, where it locks feedrate when cutting difficult materials.
By using M91, you can fix feedrates for positioning moves, such as rapid movements, and guarantee precise control over the cutting process.
Bear in mind that M91 is a machine-specific code, and its compatibility should be checked before use, as it may not be supported by all machine models.

M90 and M91 Command Differences
Plunge into the world of CNC coding and you’ll soon discover that M90 and M91 commands serve distinct purposes.
While both commands are used for adaptive control, they differ in their command syntax and application. M90 is used for adaptive feedrate control, allowing you to adjust the feedrate based on the machine’s performance.
On the other hand, M91 is used for adaptive cutting control, enabling you to adjust the cutting parameters in real-time. Code variations between M90 and M91 reflect these differences, with M90 requiring specific feedrate values and M91 requiring cutting parameter settings.
Understanding these programming nuances is vital to optimize your CNC code and achieve efficient machining operations.
Adaptive Cut Control in Action
As you venture into the domain of adaptive cut control, you’ll discover that M91 takes center stage, allowing you to fine-tune cutting parameters in real-time.
By dynamically adjusting feedrates, you can optimize cutting paths for specific materials, ensuring a high-quality finish and preventing damage to the machine or tool. With adaptive cut control, you can tackle a wide range of materials with confidence, from soft alloys to hard-to-machine materials.
Real-time adjustments enable you to respond to changing cutting conditions, ensuring that your machining operations stay on track. By leveraging M91, you can tap the full potential of your Mitsubishi FX10 machine, achieving optimized cutting paths and material versatility with ease.
G-Code and Post Processor Integration
With adaptive cut control enabled, you’ll need to integrate M90 and M91 commands into your g-code to release its full capabilities.
MasterCAM post processors simplify this process by adding these commands to your g-code, ensuring compatibility with machines like Mitsubishi FX10 and Accutex wire EDM machines. This integration enables dynamic feedrate adjustment during cutting operations, optimizing code performance and machine calibration.
You can customize your g-code to suit specific machining applications, using M90 to activate adaptive cut control and M91 to lock feedrate when needed. By leveraging post processors, you can achieve efficient and precise control of cutting operations, streamlining your production process.
Machine Compatibility and Limitations
When integrating M90 and M91 commands into your g-code, it’s essential to ponder machine compatibility and limitations, as these commands may not work universally across all machine models.
You’ll need to perform compatibility checks to confirm these commands are supported by your machine. For instance, Mitsubishi FX10 machines and Accutex wire EDM machines support M90 and M91 commands, but their manuals mightn’t document them.
Be aware of machine limitations, as the M90 command’s adaptive cut control and M91’s fixed feedrate override may not be suitable for all machining applications. Model variations can also affect compatibility, so it’s vital to verify the commands’ functionality with your specific machine before use.
