Multi-parameter surface-quality analysis

Abstract

Recent years have been rich in the research in the field of metrology. Firstly, the research focused on contact gauges, especially on contact profilometers. Consequently, with the investigation and development of materials, it was revealed that contact profilers were not sufficient and it was necessary to focus on 3D non-contact optical profilometers and surveyors. This article describes a new method of the surface control. It is a method of surface printing using the SILOFLEX© dental silicone and the subsequent evaluation. The surface-quality control is carried out using profile geometries that are divided into two basic groups. The first group consists of contact devices and the second group consists of non-contact devices. Both of these groups can use 2D- and 3D-measurement options. Subsequently, the surface quality is assessed using the amplitude parameters specified in the standards. These parameters have to be evaluated complexly using the multi-parameter analysis. This analysis is used today by more and more companies and has become an essential part of the control. It is utilized for all the material types from the engineering industry to medicine. The article deals with a non-contact measurement method. It also shows possibilities of an evaluation using the multi-parameter analysis.
