Analýza faktorů hydroabrazivního soustružení niklových superslitin

Abstract

The bachelor thesis deals with turning abrasive waterjet. The introduction describes the methodology of creating a kind of jet. Furthermore, the principle of operation is described hydroabrasive turning jet, setting jet relative to the workpiece, the types of abrasive material removal mechanism and the factors affecting the quality of the process. Dependence factors on machined surface erosion model explains. This model, based on the knowledge can yield point, to predict the final diameter of the workpiece. In the experimental part of the turning of Incoloy 925 nickel alloy with a diameter of 50 mm. This was a continuous abrasive waterjet with a pressure of 400 MPa. During the process, changing only the value of the traverse speed and examined with a surface roughness. It can be seen that by increasing the traverse speed is higher level unevenness of surface roughness of the workpiece.
