Chatter is fairly common in the world of CNC machining. Okuma Machining Navi chooses an optimal speed(s) at which your machine can avoid chatter, thereby saving operator time and maximizing productivity.
Okuma invented Machining Navi, an optional function that uses the OSP-P control and sensors to monitor chatter. If chatter is detected, the function then either recommends spindle speed changes (Machining Navi L-gand Machining Navi M-g) or automatically makes the spindle speed adjustments (Machining Navi M-i).
Machining Navi L-g
For lathe applications suppressing chatter requires a different approach, especially when turning at lower speeds. Automatic spindle variation, while maintaining safe speeds, suppresses chatter.
Machining Navi M-g
Suitable for high speed machining center applications, Machining Navi M-g uses a microphone to analyze chatter and display optimal settings for chatter-free spindle speeds.
Machining Navi M-i
Chatter vibration is measured by built-in sensors and automatically shifts RPM to the ideal speed to avoid chatter.
The result is optimized cutting at the machine’s highest performance limits. The function also helps improve the ability to test new materials and cutting tools.
