Cutting tool inserts, for instance used in steel machining, have the requirement to be toughand are therefore most often manufactured out of cemented carbides, using powdermetallurgy. Manufacturing components with powder metallurgy has its advantages in highproductivity and good net shape. The powder is spray dried and compacted to half itssintered volume. Because of friction between the powder and the pressing tool, the densityafter compaction is uneven, leading to uneven shrinkage during sintering. To get the rightshape after pressing and sintering, the pressing tool must often be compensated, which isboth expensive and time consuming. By doing computer simulations of the manufacturingprocess, the shape after sintering can be predicted an...
