Abstract— Despite the rapid development of information technology and various electronic media, paper remains the main material in the printing industry. Drilling machines plays an important role in such industry, and cardioid cams are significant parts of them. The mechanism for cutting of cardioid cam is studied in paper. Its kinematic is calculated, the equation of trajectory of cutting tool centre is obtained. The problem of calculation of cutting tool edge is considered. The optimization task for creation a mechanism, which produce the most precise trajectory of cutting edge is set. The solution od such a task is offered and optimization criteria are offered.
