The Effect of Artificial Aging Treatment and Lubrication Modes on the Cutting Force and the Chip Surface Morphology when Drilling Al-Si-Mg (A356) Cast Alloys

This article reports the effects of various artificial aging methods and lubrication modes (dry, mist, wet) on the recorded cutting forces and chip morphology in drilling Al-Si-Mg (A356) cast alloys. In the course of this work, the work part sampled were as-received alloy (T0), solution heat-treated alloy (SHT) and then aged alloys at 155°C, 180°C, and 220°C (T4, T6, T61, T7), respectively. The...

تشکیل فاز مولایت در فرایند اکسید شدن سیستم‌های Al2O3+Si، Al+Si و SiO2+Al

در این مقاله، اثر ترکیب مواد اولیه بر ویژگی?های فازی و ریزساختاری بدنه?های مولایتی بررسی شده است. سه سیستم SiO2+Al, Al2O3+Si و Al+Si با فرض اکسید شدن کامل عناصر Al و Si انتخاب شدند. مواد اولیه در محیط الکل اتیلیک توسط همزن مغناطیسی، مخلوط و پس از سپس خشک شدن، و گرانول? سازی شده و در گستره دمایی�C1600-700 حرارت دیدند. نتایج نشان می?دهد که در سیستم Al2O3+Si پس از دمای �C1450 فاز مولایت تشکیل می?ش...

Minimum Quantity Lubrication (MQL) in Machining: Benefits and Drawbacks

Micro lubrication or also known as minimum quantity lubrication (MQL) serves as an alternative to flood cooling by reducing the volume of cutting fluid used in the machining process; but not without significant health concerns. Flood cooling is primarily used to cool and lubricate the cutting tool and work piece interface during machining process. The adverse health effects caused by the use of...
