اثر طراحی ابزار بر روی اثرات حرارتی ظاهر می شود در طول پردازش دنده غلتکی

Toothing of bevel gear is a crucial operation for the automobile industry. To achieve the required performance characteristics of the gear it is essential to optimize the toothing process. Herewith, the task of understanding the proceeding the heat processes during cutting is important to forecast of the tool wear, accuracy, and undulation of the processed surface. In the article the results of numerical simulation of thermal processes appearing during processing of bevel gear are considered. This paper presents the results of numerical modeling of thermal processes occurring in a tool, workpiece, and chips during bevel gear cutting. Also the influence of the design parameters of the cutting tool on the value of maximum temperatures and heat flows occurring in the process of cutting was investigated. The approaches which were used in that paper can also be applied to other cutting processes with the removal of a complex U and / or L shaped chips (gear shaping, broach etc.)
