摘要
The vibration occurring during a micro-milling process can have impact on the surface quality. Usually the main influence on a vibration occurring during milling have cutting parameters (feed rate, cutting speed, depth of cut), workpiece material and type of milling tool. However in micro scale different phenomena can also affect on a vibration occurring during the micro-milling. In some cases repetition of experiment results is challenging. One of factors that is commonly neglected is material structure. The paper describes influence of the workpiece material (C45 steel) grain size on the vibration occurring during micro-milling. The experiment shown that for the same material, tool and cutting parameters vibration can occur or not. Only difference between two workpieces was their grain size. This leads to the conclusion that the workpiece grain size can decide if vibration occurs during micro-milling.
