Popis: The paper objective is to decrease a share of tool costs in the cost price of production manufactured at the expense of the composite and solid mills use control. In the course of research the authors used computer simulation with the finite elements. The studies proved that the composite cutters can compete with the monolithic cutters in terms of their efficiency while ensuring the required precision accuracy. Their cost is lower due to hard alloy savings. The outcomes of evaluation of the groove wall runout as a result of bending for cutters of different designs are given, and it is shown that the deviation is acceptable for engineering products. The effective application of both mills is shown. It is demonstrated that the smaller is the length of the required mill, the increasingly competitive composite mills become due to insignificant differences in their deformation compared to the deformation of the monolithic milling cutters and due to the considerable hard alloy saving. Thus, the greater length is required by the mill, the greater are the hard alloy saving, but also the greater is cutter deformation which reduces accuracy and processing performance.
