Spindle speed modulation for chatter suppression in machining process

In manufacturing industry, productivity rate and profit is crucial. Higher productivity rate means the product can be released fast, with good quality. Unfortunately to increase the productivity, manufacturer have to face a big challenge which is chatter. Chatter is a wavy marks on a product surface...
