Turning processes

U radu se kroz nekoliko poglavlja opisuju postupci obrade tokarenjem, bez eksperimentalnih ispitivanja. U nastavku su opisane geometrijske značajke dobivene pojedinim postupkom tokarenjem, kvaliteta površine, rezni alati, te izvedbe tokarilica. U prvom poglavlju opisan je općeniti uvod o tokarenju. Prikazana je podjela postupaka obrade tokarenjem kao i parametri obrade, te kinematika postupaka obrade tokarenjem. Cilj svake proizvodnje je dobiti točan i kvalitetan proizvod, stoga su u drugom poglavlju objašnjene metode određivanja hrapavosti i kvaliteta obrađene površine. Prikazane su i vrijednosti koje se postižu tokarenjem, te neki instrumenti za ispitivanje hrapavosti površine. Kako alati i strojevi imaju najvažniju ulogu u procesu izrade, u zadnjem poglavlju detaljno su opisani rezni alati i izvedbe tokarskih strojeva. Prikazana je geometrija reznih alata, te materijali za izradu alata i naprave za prihvat i stezanje obradaka, što ima veliki utjecaj na kvalitetu samog proizvoda. U nastavku su opisane različite izvedbe tokarilica, njezine prednosti i nedostaci, kao i primjena.This work describes the processing methods of turning, without experimental testing. Through several chapters you will find descriptions of geometric features obtained by the individual turning operations, surface quality, cutting tools, and lathe construction. The first chapter describes the general introduction to turning. There is presented the division of the bypass processing as well as the processing parameters and the kinematics of turning processes. The goal of every production is to obtain the correct and high-quality product, therefore, in the second chapter, the methods of determining the roughness and quality of the treated surface are explained. The values that are obtained by turning are also shown, as well as some surface roughness testers. As tools and machines have the most important role in the manufacturing process, the last chapter describes the cutting tools and the performance of lathe machines. The geometry of the cutting tools, tool materials and devices for attachment and clamping are shown, which has a great influence on the quality of the product itself. Finally, different lathe performance, its advantages, and disadvantages as well as its application, are described
