This study deals with a development of analytical estimation system for machined surface texture based on tool run-out and cutting edge profile measurement for end-mills by optical method. In the article, geometrical cutting model is proposed with a consideration of tool deflection, tool run-out and cutting edge profile. In order to obtain those analytical parameter values, we constructed certain optical equipments for measuring spindle rotation trajectory and cutting edge profile in three dimensions. Through an analytical consideration of tool run-out trajectory, we revealed that the tool run-out components (both RRO and NRRO) are geometrically transferred to the machined surface as the corresponding wavelength components. From the experimental result, wavelength spectrum between surface roughness profile and tool run-out trajectory is closely conformed to the analytical simulation.
