摘要

The invention relates to an insert for chip forming machining. The insert (10) is a body having polygonal basic shape and is provided with a cutting edge at the periphery thereof and a chip former. The chip former is provided in the shape of a plurality of ridges (23) whereby the mutual distance between adjacent ridges diminishes in direction towards the middle of the cutting edge so as to form a conical corrugated chip (30) which is forced away from the workpiece during machining.
