Fortunately, alternative methods can be employed to achieve similar results. For instance, using M30 with Block Delete (or Block Skip on older machines) can be a viable alternative. You can also set a specific number of parts to be produced using M98P251234 or utilize the tool wear function, but these methods have limitations and may not be suitable for all applications.
Machine-Specific Solutions and Considerations
You’ll find that Doosan machines require a unique approach, using M55 code at the program’s end and a standard M30 to loop and stop when the desired part count is reached.
In contrast, Haas machines employ a different method, utilizing M30 and Block Delete (or Block Skip) to achieve part counting.
It’s essential to consult your machine’s documentation or the manufacturer’s tech support to determine the best solution for your specific machine.
Doosan Machines
Configuring M54 CNC code for Doosan machines requires careful consideration of their unique specifications and capabilities.
