Sažetak
The abrasive waterjet (AWJ) cutting is currently applied to a wide range of materials; thus, this technology is implemented in different kinds of techniques. A priority benefit of this technology includes the absence of thermal effect on the workpiece. This is the reason why the AWJ is being extensively applied not only in many types of industry, but also in medicine. Possibilities of its further use however have not yet finished. One of the areas in which this technology is in the beginning is orthopaedic surgery. In order to implement this cutting technique, the experimental cutting of porcine bones "ex vivo" were performed. The surfaces created by waterjet were measured by a contact profilometer in order to quantify the surface profile parameters Ra, Rq and Rz. These experiments represent the first step of the authors in implementing the abrasive waterjet cutting technology into the orthopaedic surgery.
