With the rapid development of mechanical industry, many kinds of thin metal plates have come to be used, but these plates are difficult to cut. One of the most important subjects in machine shops is to find an effective method for the cutting of thin metal plates. Low current air plasma arc cutting is one of the cutting methods which will hopefully meet such a requirement. However, there have been few studies hitherto which deal with low current air plasma arc cutting of thin metal plates. Under such a present-day situation, the application of low current air plasma arc cutting for thin metal plates was chosen as the subject of this study, that is, the effects of cutting conditions (stand-off height, cutting speed) on cut surface quality (kerf width, bevel angle, top edge condition, surface roughness, dross adherence, etc.) were examined. From this study, the relationship between cutting conditions and cut surface quality was clarified, and it was found that application of this method to the cutting of thin metal plates (SPCC and SUS 304) is effective.
