Burr formation during dry milling of wrought aluminum alloys

In this article, a multi-level experimental study on dry milling of 2024-T351 and 6061-T6 aluminum alloys is used to prescribe an operational window to control and minimize burr height (Bh) in milling. Maximum height of exit burr and exit up milling side burr were measured. Statistical tools were then used to define the dominant process parameters on Bh. The effects of feed rate, depth of cut, friction, tool coating, insert nose radius (Re) and material properties on milling burrs profiles is discussed. The experimental results show that machining with larger Re leads to bigger exit bottom burr and smaller exit up milling side burr. In addition coated tools significantly effects on Bh in slot milling
