AB Article presents results of research activities in the area of the cutting tool condition monitoring using force signals as indices of tool wear and tool failure when hard turning. Cutting force authentically reflects changes in the tool during cutting with good accuracy. Relationship between cutting force and wear depends on work-piece/cutting tool interface and on changes of cutting conditions. Therefore, modelling as well as monitoring of tool wear is quantitative different for each work-piece/cutting tool interface and highly sensitive from cutting conditions changes, which obstruct their mutual comparison. The passive (radial) force became the largest among the three force components when cutting of hardened steel. However, the most sensitive to the changes of flank and nose wear was the mean feed force component although the passive force indicates significant increase, too. The character of dynamic value of force signal change when damage of cutting tip is presented.
