Surface Texture in Abrasive Waterjet Cutting

When cutting thick material with an abrasive wateriet, 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. An investigation was conducted to experimentafly determine the influence of the abrasive waterjet cutting parameters on surface texture. ...

Wastewater Treatment of Stone Cutting Industries by Coagulation Process

Background & Aims of the Study: The wastewater created as a result of stone cutting industries enters some pools for re-consumption so that its suspended solids settle by gravity. By taking to account the high volume of water and sludge, treatment of wastewater and removal of sludge cause many problems for stone cutting units. The objective of this study was to determine the quality of wast...

Micro Cutting Simulation of Abrasive Grains in the Grinding Process

In the current work we present approach to study the mechanism of the cutting of abrasive grains in the grinding wheel using finite element analysis (FEA). The simulation process is done by separating two abrasive grains from the grinding wheels and the microprocess of material removal in the case of surface grinding is simulated. Modelling was done on the workpiece steel S-7 and material grain...

Test Parameter Analysis in Abrasive Jet Cutting of Rocklike Materials

This paper contains investigations on the behavior of five artificial rocklike materials subjected to abrasive water jet cutting. The influence of the test parameters, i.e. applied pump pressure, traverse rate and abrasive mass flow rate was investigated, as well as the influence of several material parameters, e.g. compressive strength, Young's modulus, absorbed fracture energy and crack veloc...
