Abstract

The article studies the cutting parameters of the experimental tool with a flat milling of oak wood. The experimental tool was an end mill with interchangeable knives. The knives were made of high speed steel HS 18-0-1-5 (ISO 4957:1999). Two milling knives were additionally treated with different ion-plasma coatings by Arc-PVD method. Multilayer AlTiCrN coating was deposited on the surface of the knife B, MoC coating was deposited on the surface of
the knife C. The results of measurements have shown that the cutting power for end milling is increased with the increase in the length of milling for all three investigated knives of cutter. Maximum cutting power was achieved with
knife C. It was found out that the roughness parameter Ra of the wood surface practically does not change for knives B and C in the entire range of applied feed rates, and also slightly decreases (up to 5 μm) with an increase in the milling length and does not depend on the processing of the cutter knives edges.
