Nonparametric Assessment of Surface Shaping by Hybrid Manufacturing Technology

摘要

Development of surface metrology tries to respond to the needs of the industrial environment and to keep up with increasingly sophisticated manufacturing methods and products. However, a multitude of surface texture parameters, as well as the research equipment available on the market, often complicates the estimation and comparison of surfaces, e.g. between different branches. The authors present a method of nonparametric assessment of milled and then burnished surfaces which is alternative instrument to parametric assessment of surface topography. This method gives directly answers, whether the treatment was conducted in line with expectations. This instrument can also be helpful in a very wide spectrum of technological cases, where the cloud of points is collected by stylus and optical systems. The measurements were conducted with an AltiSurf A520 multisensor instrument, manufactured by Altimet according to own developed methodology.
