Abstract
In this paper, the profile of surfaces machined using end mills with flat and ball end tools in modeled. The real kinematics of the tool motion, the static deflection and the run out of the tool are included in the model. The cutting forces are calculated using a semi-empirical method based on orthogonal to oblique conversion of cutting coefficients. The thickness of the uncut chip is used as the critical parameter affected by the tool run out. Based on the above model, the final profile of the surface is generated and compared with existing experimental results

Abstract [Persian]
مدل‌سازی سطح فرزکاری شده با انگشتی های استوانه ای و سرکروی مارپیچ با در نظرگرفتن سینماتیک واقعی حرکت، خیز استاتیکی و خارج از مرکز بودن ابزار ارائه شده است. نیروهای برش توسط یک مدل نیمه تجربی، بر اساس داده های آزمایشات برش قائم و به کمک معادلات تبدیل برش قائم به مایل محاسبه شد. به کمک معادلات خیز تیر یک سرگیردار، خیز ابزار مدل گردید. ضخامت براده جدانشده به‌عنوان بحرانی ترین پارامتر متاثر از خارج از مرکز بودن ابزار مورد تحلیل قرار گرفت. در نهایت با در نظرگرفتن مختصات هر یک از نقاط سطح و مقدار خیز در همان نقطه، سطح نهائی بدست آمد.
