dc.description.abstractHeat distribution in machining is one of the phenomenological characteristics of this process because it significantly influences functional properties of machined surfaces. This paper deals with heat distribution during grinding of Ni alloy and its relationship to the quality of ground parts in terms of residual stresses. The analysis of the heat distribution is based on measurement of the temperature in the contact of the grinding wheel and the workpiece, and the tangential component of cutting force. The heat distribution when Ni alloy grinding differs from the heat distribution when grinding a conventional Fe alloy such as roll bearing steel mainly because of the low heat conductivity of Ni alloys. Also, the application of CBN and diamond grinding wheels significantly reduce the thermal exposition of the ground parts, primarily when applying cutting fluid. This fact significantly influences the residual stresses after grinding. The results of the analysis show that there is correlation between energy partitioning and residual stresses.cs

dc.description.abstract-enStvaranje i razdioba topline tijekom obrade odvajanjem čestica jedna je od fenomenoloških karakteristika tih postupaka, koja znatno utječe na funkcionalnost obrađenih površina. Rad se bavi proučavanjem distribucije topline tijekom brušenja nikaljnih legura i njenim utjecajem na kvalitetu brušenih površina uslijed pojave napetosti (zaostalih naprezanja). Analiza razdiobe topline temelji se na mjerenju kontaktnih temperatura između brusnog kotača i obradka te tangencijalne komponente sile rezanja. Razdioba topline tijekom brušenja nikaljnih legura različita je od one tijekom brušenja uobičajenih željeznih legura, primjerice čelika za kotrljajuće ležajeve, prvenstveno zbog njihove niže toplinske provodnosti. Također, uporaba bor-nitridnih (CBN) i dijamantnih bruseva značajno smanjuje toplinska opterećenja obradaka, prvenstveno uz uporabu rashladnih fluida. Ta činjenica znatno utječe na pojavu napetosti nakon brušenja. Rezultati analize pokazuju da postoji povezanost između razdiobe toplinske energije i napetosti.cs
