Jul 30, 2010Β· To some extent, chatter is a function of tool deflection. Unless your work is extremely thin (cutting close to the edge and creating a thin wall that can chatter), or poorly supported, the tool deflection is going to be the biggest component. If the tool doesn't deflect, it's hard to get chatter. A deflection of up to 0.001" is usually okay.
