چکیده
امروزه ماشین‌کاری و فرزکاری کامپوزیت‌ها، از اهمیت بالایی برخوردار است؛ زیرا کامپوزیت‌ها در بخش‌های گوناگونی استفاده می‌شوند و کارایی زیادی در صنایع مختلف پیدا کرده‌اند. با توجه به این امر، در این مقاله، برای صرفه‌جویی در هزینه‌ی فرزکاری کامپوزیت‌ها به بررسی میزان اثرگذاری پارامترهای مختلفی که بر روی نیروی برشی و فرسایش ابزار تأثیر گذارند، شامل سرعت اسپیندل (rpm)، نرخ پیشروی (mm/rev)، عمق برش(mm) و درصد sic، پرداخته شده است؛ تا با ایجاد شرایط بهینه، فرسایش ابزار و نیروی برشی به حداقل رسانده شود. انجام تحلیل حساسیت با توجه به معادله‌های رگرسیون نیروی برشی و فرسایش ابزار نشان داده است که سرعت اسپیندل با 63% و میزان درصد کاربید سیلیکون کامپوزیت با 22% بیشترین تأثیر را بر روی فرسایش ابزار دارند و عمق برش با 47% و پیشروی با 23% بیشترین تأثیر را بر روی نیروی برشی دارند.

چکیده English

Today, the machining and milling of composites is of great importance; Because composites are used in various sectors and have found great efficiency in various industries. Considering this, in this article, in order to save the cost of milling composites, the effectiveness of various parameters that affect the cutting force and tool wear, including spindle speed (rpm), feed rate (mm/rev), cutting depth (mm) and percentage of sic, has been discussed; To minimize tool wear and cutting force by creating optimal conditions. Performing a sensitivity analysis according to the regression equations of cutting force and tool wear has shown that spindle speed with 63% and the percentage of composite silicon carbide with 22% have the greatest effect on tool wear and depth of cut with 47% and advance with 23% have the greatest effect on cutting force.
