INFLUENCE TRAVERSE SPEED ON SURFACE QUALITY AFTER WATER-JET CUTTING FOR HARDOX STEEL
Original language description
In this study, the effect of different traverse speed of abrasive water jet (AWJ) on HARDOX 400 steel was experimentally investigated. In the experiment five different traverse speeds of 20, 40, 60, 80 and 100 mm/min were used. After the cutting the qualitative aspects, especially surface roughness and the analysis of 3D surface topography, were measured. The experiment was carried out on the water-jet machine with pump power of 18.5 kW generating working pressure 280 MPa. Few well-known relations have been proven. First of all, the growth of all surface roughness parameters with increasing traverse speed has been observed. Another relation is that the smallest values of surface roughness parameters are obtained for profile close to the upper edge cutting surface. On the contrary, the profile close to the bottom edge is characterized by a significant increase of surface roughness with increasing traverse speed. The smallest declination angle was obtained for the slowest traverse speed. The good cutting quality is associated with a slower traverse speed but longer time of cutting brings higher costs, since the process consumes more water, electricity and abrasive. Therefore, some optimization is suggested to make process sufficiently precise and economic.
