چکیده
تحقیقات در حیطه فناوری روان­کاری همواره مورد توجه محققین است. از موارد جدید در تحقیقات اخیر می‌توان به بررسی عملکرد مایعات یونی به عنوان روان­کار اشاره کرد. همچنین برای کاهش میزان مصرف روان­کار در فرایندهای مختلف، سیستمی تحت عنوان سیستم روان­کاری کمینه (MQL) مورد استفاده قرار می‌گیرد. در این پژوهش با انجام آزمایش‌های تجربی، عملکرد روغن آفتابگردان و همچنین، ترکیب مایع یونی [BMIM] [PF6] با روغن آفتابگردان به عنوان روان­کار در فرایند تراشکاری فولاد AISI 4140 با روان­کاری کمینه مورد بررسی قرار گرفته‌است. علاوه بر اثر تغییر روان­کار، اثر تغییر فاصله نازل تا قطعه‌کار و فشار سیستم MQL نیز در فرایند تراشکاری بررسی شد. طبق نتایج به دست آمده، هر چه فاصله نازل تا قطعه‌کار کاهش یابد، تأثیر روان­کاری با مایع یونی نسبت به روان­کاری با روغن آفتابگردان بیشتر می‌شود. همچنین استفاده از مایع یونی [BMIM] [PF6] به عنوان افزودنی به روغن آفتابگردان توانست تلرانس‌های دایره‌ای و استوانه‌ای قطعه‌کار را در مقایسه با روان­کاری با روغن آفتابگردان، به ترتیب 12 و 22 درصد کاهش دهد.

چکیده English

Research in the field of lubrication technology is always of interest to researchers. One of the new cases in recent researches is the study of the performance of ionic liquids as lubricants. Also, to reduce the amount of lubricant consumption in various processes, a system called minimum lubrication system is used. In this research, the performance of sunflower oil and also the combination of ionic liquid [BMIM] [PF6] with sunflower oil as a lubricant in the turning process of AISI 4140 steel with minimum lubrication has been investigated. In addition to the effect of changing the distance between the nozzle and the workpiece and the pressure of the MQL system was also investigated in the turning process. According to the obtained results, as the distance between the nozzle and the workpiece decreases, the effect of lubrication with ionic liquid increases compared to lubrication with sunflower oil. Also, the use of ionic liquid [BMIM] [PF6] as an additive to sunflower oil was able to reduce the circular and cylindrical tolerances of the work piece by 12 and 22%, respectively, compared to lubrication with sunflower oil.
