Abstract
The purpose of this research is to investigate the influence of high-pressure water cutting on efficiency of cutting rubber mats to develop into rubber puzzle mats. The cutting variables, i.e. abrasive mass flow rate, stand-off distance between a nozzle and the workpiece, water pressure and cutting speed were taken into account. The effects of cutting parameters on the subsequent quality, specifically surface roughness, kerf width and kerf bevel angle were explored. The three-level full factorial experimental design was applied to define optimization of cutting parameters (p<0.05) and ideal cutting conditions were observed. From the experiment, it was found that the abrasive mass flow rate factor, stand-off distance between nozzle and workpiece, water pressure and cutting speed have a significant influence on cutting characteristics. Optimal cutting conditions for 7mm thickness, 50–90 Shore A rubber puzzle mats were determined as follows: abrasive mass flow rate of 350 g/min, stand-off distance of 2 mm, jet pressure of 300 MPa and cutting speed of 2,000 mm/min. Practical applications of these optimal parameters for 10×10 cm rubber puzzle mats proved that cutting process could be completed within 3 minutes. This is acceptable for industrial manufacturing. The cut quality characteristics were exposed as 3.15 μm top surface roughness, 3.37 μm bottom surface roughness, 1.35 mm top kerf width, 1.28 mm bottom kerf width and 1.83 degree kerf bevel angle, respectively. The results of this study can prove beneficial to rubber mats manufacturers by increasing the value of rubber mats by post cutting process for creating rubber jigsaw mats.
