hello i am not referring to those classical vibrations that lead to wavy part aspect, but to the vibrations caused by cutting edge making contact with the part
thus the shock when tool enters the material, especially at 1st cut, when it hits the surface layer ( the crust )
i tried to minimize the number of such contacts, and also reduce the specs in such areas
material is not uniform, and these differences are causing effects that are increased with higher speeds; if i would cut it at lower rpm, etc, i would definetly break the chips more often, but also program time would be longer
i am looking for some tips to eliminate ocasional wrapping at higher rpms
i once heared that high pressure cooled coolant does wonders, but i don't have such equipment / kindly
