Surface Characterization by Accurate Measurement and Image Processing Systems on Machined Surfaces of Precision Cutting Tools

摘要

High precise measurement techniques and surface structure analysis are required in advanced fields of in- terchangeable manufacturing and precision engineering. This study presents the characterization of the surface roughness of the machined milling cutters by exper- imental precision measurements and the image pro- cessing tool. The data obtained are compared to assess the surface characterization parameters and computa- tional data in terms of precision, accuracy, sensitivity, repeatability and resolution. In the experimental measurement phase, the roughness measurements and surface topography characterization were performed in the nanotechnology laboratory using the stylus profilometry and digital microscopy. The compu- tational phase was performed using an image processing toolbox with precise evaluation of the roughness for the machined metal surfaces of the end mill cutting tool. The surface parameter database is established ex- hibiting an advantage over the traditional method. This study reveals a comparison methodology of the end mill surface parameters using both stylus readings and im- age processing software for widely used end mill cutting tools that have considerable effect on characterization of sensitive manufacturing surface of millings.
