Plastiform roughness control procedure with contact

The Plastiform P80 Ra, as its name suggests, is a molding product that can copy the Ra roughness of a surface and reproduce it identically. This capability allows it to be used in cases where the surface to be inspected is not accessible to the measuring instrument. Roughness evaluations with Plastiform Definition Roughness corresponds to the irregularities present on a surface, due to differences in level. The Arithmetic [...]

The Roughometer – Measuring Surface Condition

During machining, regardless of the precision of the machine used, it is to be expected that the surfaces will have irregularities. These irregularities are micro-geometric asperities due to imperfect machine tools (yes! Perfection does not exist!). The measure of these imperfections is essential. For more than 80 years, measuring surface finish has been used to improve product performance. By qualifying an average to these defects it is possible [...]

Roughness Ra | Arithmetic Average of Roughness Profile

The roughness Ra is, in mechanics, an average characterizing the surface condition of a part or material. In industry, roughness control is part of the dimension validation process and ensures part conformity during machining. There are other indicators that characterize the roughness of a surface, but in this article we will focus on the general surface condition of the control area. What is the roughness Ra? Definition The [...]
