Abstract:
This article presents the results of works aiming at observations of wearing high speed steel (HSS) milling blades, coated with application of ZeroFlow gas nitriding method, after peripheral machining of dry beech wood. The thin nitrided layer on a HSS blades of HS18-0-1, T grade, and HS6-5-2, T-M grade influences the nature and value of changes in VBf , VBw , VBs, and ρmi, cutting edge wearing parameters, as the cutting distance increases. From the point of view of minimum cutting edge round up, the HS18-0-1 steel grade seems to be superior under the HS6-5-2 steel grade. From the perspective of the cutting edge recessions measured on the: (*) clearance surface VBf , and (**) rake surface VBs, the HS6-5-2 steel grade seems to be slightly better. The cutting edge recession measured on the bisector of the wedge angle VBw appeared to have similar values for both examined steel grades, independent of the values of other controlled parameters: Ls – the cutting path; βf – the cutting edge wedge angle; BaN – the Barkhausen noise indicator. An increase in the Barkhausen noise indicator slightly decreases the cutting edge recessions expressed by VBf , VBw and VBs parameters.
