In order to improve the accuracy of abrasive water jet (AWJ) machining the precise value of the jet diameter has to be known. A measuring device consisting of a load cell and a wear resistant probe was developed. The device measures the force of the jet while it passes over the edge of the probe. If the feed rate of the jet is constant and the time needed for jet to pass is known, the diameter can be determined. The measurement of the AWJ was performed for two different focusing nozzles of different diameters.

Simulation of a throughfeed centreless grinding process in a virtual environment (VE) is presented. The developed simulations are based on an analytical grinding gap model describing the grinding gap macro geometry and workpiece kinematics. The model is embedded in a desktop application (Cegris), which facilitates regulating wheel truing and the determination of set-up variables. The Cegris is ported to a CAVE (CAVE Automatic Virtual Environment) for an interactive visualisation of the process.
