Impact of stylus size in roughness measurement

Popis výsledku v původním jazyce

In technical practice, the concept of surface roughness plays an irreplaceable role. This property has been evaluated by various techniques and mathematical approaches since the 1920s. However, evaluation is often underestimated and reduced to find the Ra or Rz parameter. This occurs regardless of methodology. It represents a totally unacceptable simplification of the issue. The following article will clarify a ”small“ part of this vast issue. Nowadays, there are two basic options for measuring roughness. The first option is the contact method; the second option is the non-contact measurement method. Each method has its advantages and disadvantages and is typically used only for a specific application (2D or 3D roughness measurement).This paper focuses on the contact measurement of 2D surface area, specifically the choice of the size and shape of the stylus tip. This article maps the problem of choosing a stylus tip in the interval where the standard ISO 4288: 1999 permits usage of both stylus tip sizes. This concerns the roughness range Ra = 0.1 ÷ 2 μm (aperiodic surfaces) and the range of the parameter Rsm = 0.13 ÷ 0.4 mm (periodic surfaces). The article further compares the use of a new stylus and an old (worn) one.
