Using tool wear to increase process stability when milling Al7075 and AISI 4140+QT

Abstract One of the main limits productivity during cutting processes is occurrence regenerative chatter. Due to these self-excited vibrations, load capacity machine components, tool as well performance cannot be fully utilized. There are several methods stabilize milling process. use increased process damping, which results from contact tool’s flank face and workpiece. The wear land naturally increases between However, this effect has not been used increase in processes. This paper investigates with experiments numerical simulations how affects stability aluminum steel. Therefore slot side tests were carried out tools various states wear. It could shown that increasing allows raise depth cut a p up 300% machining perform higher productivity.
