Machining method and device

摘要

To improve machining qualities by removing shavings, an improved method involves adjusting the form of a cutting tool 1 close to a cutting edge 12 during machining operations such that the shavings 21 of removed material break off. The form is preferably adjusted in a periodical or pseudo-periodical manner with amplitudes and frequencies suitable for machining conditions. A machining tool 1 for implementing the method comprises a movable chip breaker 13 such as an element fitted onto the machining tool and a front part 31 of which is moved relative to the cutting edge 12 by means of an actuator 33, which may be a piezoelectric actuator receiving signals from a controlling means.
