Assessment of Surface Structure of Machined Surfaces

Abstract

This paper deals with basic methodology of surface evaluation of functional surfaces, which were prepared by various machining methods (turning, milling and grinding). Here are the basic 2D (profile) parameters and 3D (spatial) parameters and their properties in relation to the machined surface. Parameters of machined surfaces were obtained by CCI Lite Coherence Correlation Interferometer from Taylor Hobson and evaluated using the TalyMap Platinum software. The article further demonstrates the inappropriateness of the surface structure assessment with only the parameter Ra (mean arithmetic deviation of the profile), which is the most common method in technical practice. This methodology extends the possibilities of a comprehensive assessment of exposed surfaces of machine parts.

Accuracy and topography analysis of hard machined surfaces

“…Note that 0.3 mm feed cannot be chosen if the roughness of the ground surface is specified. In case of a relatively high feed of the turning procedure the imprint of the tool in the base plane influences the roughness values to a high extent, while in grinding the increase of the feed leads to the increased torn feature of the surface [19].…”

Pla Material Surface Properties Evaluation Prepared by Additive Technology

“…Samples obtained by 3D printing technology were evaluated for surface microgeometry on a TalySurf CLI1000 device. The surface texture was measured with an inductive touch sensor [14]. The measurement took place on an area of (2 x 2) mm.…”

The use of FIB for the preparation of a structure analogous to the natural sur-face and its replication by selected types of polymers

“…FIB-SEM is usually used for imaging of the structures of the different materials on a micrometer and nanometer scale for micro-, nanopreparation of the structures. [2,3,4,5,6,7,8] The content of the presented text is experimental verification of the possibility of using a focused ion beam for the preparation of surface structures analogous to natural patterns and the use of the two-step imprinting method to obtain replicas of the surface. Different polymeric materials (water-alcohol-soluble polymers, amorphous and crystallizing polymers) were used for the experiment to describe their ability to replicate the surface formed by FIB.…”
