چکیده

عملکرد سیالات برشی در ماشین کاری مواد مختلف به منظور بهبود کارایی و اثربخشی در هر فرآیند ماشین کاری حیاتی است. هدف از انجام این پژوهش بررسی تأثیر استفاده از روش خنک کاری کرایژونیک بر روی عمرابزار و توان مصرفی دستگاه در فرآیند تراشکاری فولاد زنگ نزن آستنیتی 304 است. بدین منظور سرعت برشی و زمان ماشین کاری هرکدام در سه سطح به عنوان متغیرهای مسئله انتخاب شدند. روش رویه پاسخ، با به کارگیری طرح مرکب مرکزی، به منظور برنامه ریزی و تحلیل آزمایش های تجربی مورد استفاده قرار گرفت. ارتباط بین پارامترهای ماشین کاری و متغیرهای خروجی با استفاده از روش رویه پاسخ مدل سازی شدند. همچنین برای بررسی کفایت و مؤثر بودن مدل ریاضی و متغیرهای مربوطه، آنالیز واریانس انجام شد. نتایج حاصله تطابق خوبی را بین مقادیر اندازه گیری شده سایش ابزار و توان مصرفی دستگاه و مقادیر پیش بینی شده مدل توسعه یافته نشان دادند. با استفاده از روش آنالیز واریانس، مدل های ریاضی مناسبی برای پاس خهای خروجی با درنظر گرفتن ترم های موثر و مقادیر P کمتر از 05 / 0 )سطح اطمینان 95 %( به دست آمدند. پس از انجام آزمایش های تجربی و تحلیل و بررسی نتایج، مشخص گردید استفاده از خنک کاری کرایژونیک در مقایسه با ماشین کاری خشک باعث کاهش سایش ابزار تا 5/ 67 % و کاهش توان مصرفی دستگاه تا 24 % می شود.

چکیده [English]

Performance of cutting fluids in machining of different materials is critical importance in order to improve the efficiency of any machining process. The objective of this research is investigation the effects of cryogenic cooling on tool wear and power consumption in the turning process of AISI 304 austenitic stainless steel. Cutting speed and cutting time each at three levels were selected as cutting variables. Response surface methodology (RSM), employing a face-centered central composite design scheme, has been used to plan and analyze the experiments. The relationships between machining parameters and output variables were modeled using RSM. Analysis of variance (ANOVA) was performed to check the adequacy of the mathematical model and its respective variables. The results showed a good agreement between the measured tool wear and power consumption and predicted values obtained by developed models. Suitable mathematical models for the response outputs were obtained using the ANOVA technique, in which significant terms were chosen according to their p values less than 0.05 (95% of confidence interval). When experiments and analysis of results were done, it is observed that tool wear was decreased till 67.5% and power consumption was decreased till 24% in cryogenic cooling method when compared with dry machining.
