description The method of manufacturing thin-walled components by chip machining, which improves the roughness and accuracy of the machined surface, is carried out with a milling cutter made of sintered carbide with a combined geometry by gradually removing material along a spiral with machining parameters: - cutting speed is from 30 to 300 m.min-1 - feed per tooth is from 0 .02 to 0.20 mm - the maximum axial depth of cut is equal to the distance from the highest point on the side cutting edge to the point where the rounding of the tip rε begins, where the cutter plunges into the material along a spiral path towards the bottom and the material is removed by the side cutting edge and at the same time the main cutting edge with tip radius and smoothing surface. Spôsob výroby tenkostenných komponentov trieskovým obrábaním zlepšujúci drsnosť a presnosť obrobenej plochy sa uskutočňuje frézou zo spekaného karbidu s kombinovanou geometriou postupným odoberaním materiálu po špirále s parametrami obrábania: - rezná rýchlosť je od 30 do 300 m.min-1, - posuv na zub je od 0,02 do 0,20 mm a - maximálna axiálna hĺbka rezu sa rovná veľkosti vzdialenosti od najvyššieho bodu na vedľajšej reznej hrane do bodu, kde začína zaoblenie hrotu rε, kde dochádza k zanáraniu frézy do materiálu po špirálovej dráhe smerom ku dnu a dochádza k ubratiu materiálu vedľajšou reznou hranou a zároveň aj hlavnou reznou hranou s polomerom hrotu a hladiacou plôškou.
