Understanding Chatter in End Milling End milling is widely used for manufacturing precision components, but chatter during machining can cause irregular surface patterns, reducing dimensional accuracy and overall quality. This article explores practical techniques to suppress chatter and improve machining stability. Identifying Chatter in Machining Do you notice irregular patterns on your machined surfaces? These are signs of chatter, a vibration that negatively impacts surface finish and accuracy. What Causes Chatter? The primary cause of chatter is tool deflection. As shown in the diagram, when force is applied from one side, the tool deflects in the opposite direction, generating vibrations...
