An experimental investigation on the machining characteristics of microscale end milling

摘要: This paper discusses an experimental approach to assess the machining characteristics in microscale end milling operation through a systematic experimentation procedure. Microchannels were machined on brass plates using carbide mill of 1 mm diameter analyze effect chip load (feed per tooth) and cutting speed surface roughness, specific pressure, forces during microend operation. The tangential radial components analyzed with help three-dimensional model force signals acquired KISTLER dynamometer. Feed tooth interaction identified as critical parameters affecting roughness microchannel. Applying concept elastic recovery side wall microchannels, minimum thickness above micromilling was evaluated 0.97 μm, result validated by drastic increase pressure erratic behavior below μm.
