Surface roughness measurements in finish turning

The International Journal of Advanced Manufacturing Technology, 1996
A new approach is proposed for the on-line measurement of the maximum peak-to-valley roughness,Rmax, of a finished-turned surface in the feed direction. The method is based on solving the inverse problem of light scattering by using a linear least-square estimate of the angular scattered light pattern reflected from a surface.

Surface Roughness of Composite Resins Before and After Finishing

Acta Odontologica Scandinavica, 1972
The surface roughness before and after polishing with sand paper discs, cuttlefish discs, and aqueous suspensions of pumice was studied on 6 composite resins (Adaptic ®, Addent 12 ®, Blendant®, Dakor®, D.F.R.® and TD 71®) and two reference materials (Sevriton Simplified® and Biotrey®), with an apparatus, type Perth-O-Meter S4 BD Lowener, where ...

AFM in Surface Finishing: Part II. Surface Roughness

Transactions of the IMF, 2003
This practical topics paper, the second in a short series concerning the use of atomic force microscopy (AFM) in surface finishing, focuses on various types of surface roughness measurement that can be obtained from AFM data. Surface roughness can greatly affect optical, tribological and catalytic properties of surfaces.

Microremoval modeling of surface roughness in barrel finishing

The International Journal of Advanced Manufacturing Technology, 2013
This paper presents a model to describe the evolution of the roughness profile machined by barrel finishing (BF) operation. It is based on the measure of the material removal (MR) and on the assumptions that no plastic deformation and cutting of peak take place. In order to obtain these information, a morphological procedure has been developed based on

Simulation of the surface roughness formation process in finishing

Chemical and Petroleum Engineering, 1983
Geometric, energy, and impulse models were developed to study the interaction of the abrasive and the ground surfaces in finishing. The geometric and energy models describe the process of finishing in the case of the use of tools with a fastened abrasive.

A close look at the rough terrain of surface finish assessment

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 1998
Diminishing tolerances, enhanced reliability and the need for predictable life-spans for products have emphasized the significance of surface finishes of manufactured parts. Over the years, there has been a considerable amount of development in this area.

Surface roughness and material removal models for magnetorheological finishing

International Journal of Abrasive Technology, 2013
This paper presents an experimental approach to verify the surface roughness and the material removal models previously proposed by Wan et al. The purpose is to adapt the models to be used for magnetorheological finishing (MRF). Experiments were carried out to verify the models for different tool revolution and different tool-to-surface gaps.

Waterjet rough finishing of stone surface

2011
The paper deals with the assessment of the potential application of plain waterjet for surface treatment of stone materials as an alternative to technologies traditionally employed for this task, like bush-hammering, sand-blasting and flaming.Waterjetting has been already proposed in the market for rough finishing of surfaces making use of a fast ...

Influence of Ultrasonic Finishing on the Surface Roughness of Ship Components

Russian Engineering Research, 2019
The influence of plastic deformation by ultrasonic smoothing on the surface roughness of 17Kh18N9 and 20Kh1M1F1TR steel billet in finishing is studied. In the experiments, a D-optimal Hartley–Kono design for four factors is employed. The four factors are the speed of billet rotation, the supply, the clamping force, and the ultrasonic power.
