Micro-milling Processes: A Review

The micro-milling is a micromachining process which can be characterized by the interaction of sharp rotating microtool and workpiece. This paper presents a brief review of various conventional and modern micro-milling techniques. The aim of this study is to introduce various micro-milling techniques so far developed such as CNC-based conventional micro-milling technique, advance micro-milling processes (AMMPs) and hybrid micro-milling processes (HMMPs) such as micro-milling electrochemical spark machining (MM-ECSM) which shows a massive possibility for production of miniaturized three-dimensional structures on hard and brittle materials. The author’s research focuses on MM-ECSM laying emphasis on its future growth in R&D.
