Abstract
A cutting insert for chip forming machining tools is formed with a chip surface whose chip or rake angle increases with increasing cutting depth. In this manner the cutting edge becomes stronger closer to the operative cutting insert comer, where the work load is the largest. Simultaneously, the rake angle increases and the cutting forces diminish towards increasing cutting depth, where the specific work load is smaller.
