چکیده
سوراخ‌کاری سنتی مواد سخت و شکننده از جمله چدن‌های خاکستری به دلیل وجود ذرات ساینده کاربیدی و سیلیکونی در ساختار آن، موجب سایش زیاد ابزار و کاهش عمر مته شده و در نتیجه دقت و کیفیت سوراخ نیز افت پیدا می‌کند. هدف از این تحقیق، بهبود کیفیت سطح و افزایش عمر ابزار مته در سوراخ‌کاری چدن خاکستری است. استفاده از روش‌های پیشرفته و نوین در فرایندهای ماشین‌کاری سنتی می‌تواند باعث بهبود شرایط ماشین‌کاری شود. در این مقاله اثر استفاده از ارتعاشات فراصوت بر سوراخ‌کاری چدن خاکستری مورد مطالعه قرارگرفته است. ابتدا طراحی و تحلیل ابزار ارتعاشی به کمک نرم‌افزار آباکوس انجام شده و پس از ساخت، مجموعه ارتعاشی فراصوت بر روی ماشین فرز کنترل عددی نصب گردیده است. نتایج تجربی نشان می‌دهند که استفاده از امواج فراصوت موجب کاهش سایش ابزار تا 30 درصد و بهبود نسبی عمر آن شده و همچنین باعث افزایش کیفیت سطح سوراخ تا 20 درصد و بهبود گردی سوراخ در عملیات سوراخ‌کاری چدن خاکستری شده است.

چکیده English

Traditional drilling of hard and brittle materials, including grey cast iron, causes excessive tool wear and reduced drill life due to the presence of abrasive carbide and silicon particles in its structure, resulting in reduced hole accuracy and quality. This research aims to improve surface quality and increase drill life in drilling grey cast iron. Using advanced and modern methods in traditional machining processes can improve machining conditions. In this article, the effect of using ultrasonic vibrations on grey cast iron drilling has been studied. First, the design and analysis of the vibrating tool were carried out using Abaqus software, and after manufacturing the ultrasonic vibrating set, it was installed on the computer numerical control milling machine. Experimental results show that the use of ultrasonic waves has reduced tool wear by 30% and improved its life, while also increasing the quality of the hole surface by 20% and improving the roundness of the hole in gray cast iron drilling operations.
