Study of Cutting Temperature in Orthogonal Milling
Finite Element Method (FEM) based techniques are available to simulate metal cutting processes and offer several advantages including prediction of tool forces, distribution of stresses, and temperatures, estimation of tool wear, and residual stresses on machined surfaces, optimization of cutting tool geometry, and cutting conditions. However, work material flow stress and friction characterist...
متن کاملAn Integrated Analytical Thermal Model for Orthogonal Cutting with Chamfered Tools
In this study, an analytical slip-line approach is utilized to investigate the friction factor at the tool-chip interface and dead metal zone phenomenon in orthogonal cutting with chamfered tools. Analytical thermal modeling of chamfered tools is also formulated and integrated into the model. Orthogonal cutting of AISI 4340 steel is performed. Measured forces are utilized in identifying the fri...

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...
Effect of cutting parameters on tool-chip interface temperature in an orthogonal turning process
The aim of this paper is to investigate the effect of cutting speed and uncut chip thickness on cutting performance. A Finite Element Method (FEM) based on the ABAQUS explicit software which involves Johnson-Cook material mode and Coulombs friction law was used to simulate of High Speed Machining (HSM) of AISI 1045 steel. In this simulation work, feed rate ranging from 0.05 mm/rev to 0.13 mm/re...
