چکیده

آلیاژ اینکونل 718 از ابرآلیاژهای پایه نیکل است که به دلیل مقاومت بالا در برابر حرارت، فشار و خوردگی، کاربرد گسترده‌ای در صنایع پیشرفته مانند هوافضا و انرژی دارد. ماشینکاری این آلیاژ به دلیل سختی بالا و تمایل به سایش ابزار، یکی از چالش‌برانگیزترین فرآیندها در تولید قطعات دقیق محسوب می‌شود. در این پژوهش، اثر پارامترهای ماشینکاری بر سایش ابزار و زبری سطح در فرآیند تراشکاری اینکونل 718 بررسی شده است. با استفاده از طرح آزمایش تاگوچی و روش بهینه‌سازی مطلوبیت، تأثیر نرخ پیشروی، عمق برش، سرعت دورانی و نوع اینسرت بر سایش ابزار و زبری سطح ارزیابی شد. نتایج نشان داد که نرخ پیشروی بیشترین تأثیر را دارد و عمق برش نیز نقش مهمی در سایش ابزار ایفا می‌کند. همچنین اینسرت DNMG سایش کمتری نسبت به TNMG ایجاد کرد. شرایط بهینه ماشینکاری برای کاهش سایش ابزار و زبری سطح شناسایی شد. این نتایج می‌تواند به بهبود فرآیند ماشینکاری آلیاژهای مقاوم به حرارت کمک کرده و موجب افزایش بهره‌وری و کاهش هزینه‌های تولید شود.

چکیده English

Inconel 718 is a nickel-based superalloy widely used in advanced industries such as aerospace and energy due to its excellent resistance to heat, pressure, and corrosion. However, machining this alloy is highly challenging due to its hardness and tendency to cause rapid tool wear, making it a demanding process for producing precision components. This study examines the effects of machining parameters on tool wear and surface roughness during the turning of Inconel 718. Using the Taguchi design of experiments and desirability optimization method, the influence of feed rate, depth of cut, spindle speed, and insert type on tool wear and surface roughness was evaluated. The results revealed that feed rate had the most significant impact, while depth of cut also played a critical role in tool wear. Additionally, DNMG inserts exhibited lower wear compared to TNMG inserts. Optimal machining conditions were identified to minimize tool wear and surface roughness. These findings can enhance machining processes for heat-resistant alloys, improve efficiency, and reduce production costs.
