Cylindrical grinding is an important way to form the external shape error of crank journal, and accuracy consistency directly affects interchangeability products. To study a dynamic model wheel-crankshaft system based on Timoshenko beam established, transition process simulation algorithm with iterative convergence force-transient amount cycle adapted proposed, which realizes roundness journal ...

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...
