Cost reduction—shorter cycle times and higher productivity—is required to compete in today’s global market.
Machining Navi, with clear visuals of complex cutting conditions, is a breakthrough tool that enables the machine operator to navigate the machine and tool capabilities to their best performance levels.
We know there is harmonic motion, or periodic vibration, related to machine tool spindle speed and chatter.
As the wave cycles on the right show, chatter occurs in the unstable region, while the stable region is chatter-free.
Chatter vibration is measured by built-in sensors, and spindle speed is automatically changed to the optimum speed. In addition, advanced graphics of the optimal cutting conditions represent effective alternatives to suppress various chatter characteristics throughout the low to high speed zones.
Machining Navi M-gⅡ displays suggestions for the best spindle speed from chatter noise picked up by the microphone. The effect can be quickly checked by selecting one of the suggested spindle speeds with a single touch. M-gⅡ+, which is available for machines with built-in spindles, controls chatter by changing the spindle speed during machining at low speeds.
Chatter vibration is measured by built-in sensors, and Machining Navi automatically changes spindle speed to the optimum speed.
In other words, vibration measurement, optimum spindle speed calculations and spindle speed adjustments are then made automatically.
Based on the chatter noise captured by the microphone, Machining Navi displays a number of optimal spindle speed possibilities on the screen. The operator can change to the indicated spindle speed with a single touch and immediately confirm the result.
Chatter in a lathe can be suppressed by changing spindle speeds to the ideal amplitude and wave cycle—without decreasing spindle speed.
