Abstract:Porazdelitev toplote pri strojni obdelavi je ena od femenoloških značilnosti tega postopka, ker pomembno vpliva na funkcionalne lastnosti obdelanih površin. Prispevek obravnava porazdelitev toplote pri brušenju titanove zlitine VT9 in njeno razmerje do kakovosti brušenih delov, ki jo predstavljajo zaostale napetosti. Analiza porazdelitve toplote temelji na merjenju temperature na stiku brusa in obdelovanca ter obodne komponente rezalne sile. Porazdelitev toplote pri brušenju titanove zlitine VT9 se razlikuje od porazdelitve toplote pri brušenju običajnega jekla za kotalne ležaje (14.209.4), kot tipičnega predstavnika brušenih kaljenih jekel in sicer predvsem zaradi majhne toplotne prevodnosti titanijevih zlitin. Nadalje uporaba CBN in diamantnih brusov znatno zmanjša izpostavljenost brušenih delov toploti, predvsem kadar se uporablja hladilno-mazalna tekočina. To dejstvo pomembno vpliva na zaostale napetosti po brušenju. Rezultati analize kažejo, da obstaja močna povezava med porazdelitvijo energije in zaostalimi napetostmi.

Title:Analysis of the heat distribution when grinding of a VT 9 titanium alloy and its relation to residual stresses
Abstract:Heat distribution during machining is one of the phemenological of this process becaus it significantly influences the funktional properties of machined surfaces. This paper deals with heat distribution during the grinding of a VT9 titanium alloy and its relationship to the quality of ground parts in terms of residual stresses. The analysis of the heat distribution is based on a measurement of the temperature in the contact of the grinding wheel and workpiece, and the tangential component of the cutting force.The heat distribution when grinding a VT9 titanium alloy differs from the heat distribution when grinding a conventional (14 209.4) roll-bearing steel (a typical representative of ground-hardened steels) mainly because of the low heat conductivity of titanium alloys. Also the application of CBN and diamond grinding wheels significantly reduces the thermal exposition of the ground parts, primarly when applying cutting fluid. This fact significantly influences the residual stresses after grinding. The results of the analysis show that there is a strong correlation between energy partioning and residual stresses.
