What is the function of the G05 P10000 code, and what machining process does it activate?

The function of the G05 P10000 code is to activate High-Speed Machining (HSM) mode on certain Fanuc CNC controls. G05 is a general-purpose G-code that activates various advanced control features, and the P-code specifies which feature to activate. G05 P10000 specifically enables the advanced lookahead and processing capabilities of the control, optimizing it for high-speed, high-accuracy machining. The machining process it activates is typically high-speed milling of complex surfaces. When HSM mode is enabled, the CNC control increases its lookahead buffer, allowing it to process more G-code blocks in advance. This enables the control to anticipate changes in the toolpath and adjust the feedrate and acceleration accordingly, resulting in smoother and more efficient machining. It also allows the control to use more advanced interpolation algorithms, such as NURBS (Non-Uniform Rational B-Splines) interpolation, to create smoother curves and surfaces. G05 P10000 is often used in conjunction with CAM software that generates toolpaths optimized for high-speed machining. These toolpaths typically feature small stepovers, high feedrates, and smooth, continuous movements. Activating HSM mode improves the machine's ability to accurately follow these toolpaths, resulting in improved surface finish, reduced cycle times, and increased tool life. Not all machines support G05 P10000. It requires a specific option package to be enabled on the Fanuc control. Using G05 P10000 on a machine that does not support it will typically result in an alarm.
