A cylindrical plunge grinding process was modeled to investigate nonlinear regenerative chatter vibration. The rotating workpiece a slender Euler–Bernoulli beam, and the wheel rigid body moving towards at very low feed speed. numerical method proposed provide critical boundaries for chatter-free grinding. It demonstrated that intersection set surrounded by these region considered parameters. Wh...

In metal machining, regenerative chatter seriously affects tool life, part surface quality and cutting efficiency. To suppress generated during milling, researchers have proposed a variable spindle speed technique. But the previous VSS milling model is based on two degrees of freedom system (two-DOF). this paper, three-DOF suitable for thin-walled parts by introducing axial contact angle. The i...

This paper introduces a new switching logic inspired by the hysteresis switching logic considered in 7,11]. The new logic also uses hysteresis to prevent chatter, but unlike its predecessor in 7, 11], it is \scale-independent" as well. The logic is shown to have the requisite properties for adaptive control applications.

The future of the milling process is fully autonomous operation machine tools. Developments in terms automation and tool design are now enabling operation. However, optimization stability itself still remains a challenge. Chatter most significant bottleneck, as such, it should be constantly monitored to ensure stable process. This work proposes sensor-integrated vice using an MEMS accelerometer...
