Aspheric surface finishing by fixed abrasives
The International Journal of Advanced Manufacturing Technology, 2006This paper presents a method for the finishing of aspheric surfaces using fixed abrasives. The strategy is to remove a specified amount of material from the surface. The method assumes concentric tool paths perpendicular to the axis of the surface. The key parts of the method are: (1) efficient computation of the material removal profile for each tool ...

Improving abrasion wear by surface treatment
Wear, 1989Abstract An increase in the abrasive wear resistance of hardened and tempered hot-work die steel can be achieved by the use of surface treating processes, such as nitrocarburizing, plasma nitriding and spark discharge cladding, which produces a hard surface layer of WC-Co alloy.

Surface Waviness in Abrasive Waterjet Offset-Mode Turning
Applied Mechanics and Materials, 2014In this paper, surface waviness quality in abrasive waterjet offset-mode turning has been studied regarding variations of some process parameters. Influence of five main operational parameters such as water pressure, cutting head traverse speed, abrasive mass flow rate, workpiece rotational speed and depth of cut on surface waviness of turned parts ...

Abrasion resistance of surface layers
1998A number of surface layers obtained by coating and surface treatments i.e. DLC, SiC, SiC+DLC, Al_2O_3, Al_2O_3+Phosphates, CrN, case hardening and boriding were tested both in a "dry sand / rubber wheel" apparatus and in service. The service test was carried out in a vegetable oil factory. The screen bars of an oil extracting press were surface treated

Abrasion resistance of transport roll surfaces
Wear, 1995Abstract The manufacture of thin plastic webs such as those used in the manufacture of photographic films and magnetic media requires transport of webs over many rolls. Wrap angle of the web on rolls varies from a few degrees (tangential contact) to 180°. Some rolls are driven by the moving web and some are externally driven.

Surface texture in abrasive waterjet cutting
Journal of Manufacturing Systems, 1991Abstract When cutting thick material with an abrasive waterjet, the surface area can be characterized by two texture types. At the top of the cut, the surface texture is smooth. At the bottom, the slurry jet exiting the workpiece forms large striations in the surface.
