ABSTRACT

The paper shows the cutting behavior of the three high-speed steels, which were thermomechanical treated. The performed studies highlight that unconventional treatment (thermomechanical) applied to the high-speed steels improves their technological properties. To benefit from this improvement, the deformation degree applied at studied steel must be up to 70% (ideal between 50-70%). Thermomechanical treated steels were used in the manufacturing of various types of cutting tools, which were subsequently tested in the cutting process. The volume of processed results being great, the paper presents the cutting behavior of the disk-type of milling cutters (disk cutter). Through geometry and shape this type of tool is suitable to be processed by thermomechanical treatment. In tests were used both normal cutting regimes and hard (specific to this steels). The performances of cutting tools made through the thermomechanical treatment are superior to those conventionally manufactured. Specifically, regardless the cutting speed or time, the cutting tools from first category are worn less than those classics.
