An experimental study of cutting abilities of an abrasive water jet system
연마제 혼합액 제트의 절단 성능에 관한 연구
Abstract
A jet cutting system is a new concept of cutting device wihch requires high pressure up to thousands of atmospheric pressure. The use of water as a cutting medium brings in many of working advantages such as no dust, no gas, and no thermal distortion. And an introduction of abrasives into the water jet flow increases signigicantly cutting abilities and improves cutting performance. Cutting with abrasive water jet involves many operating variables, including design of the cutting system. For efficient cutting, the operating parameters have to chosen properly. In spite of several attempts to develop the cutting model theoretically, all of the optimization of the operating parameters is based upon exerimental results of each jet cutting system. In this paper, the effect of the parameters was measured and analysed in terms of pressure, abrasive, and transverse rate of a workpiece. Most of all, sufficient feeding of abrasives is the most important factor for efficient cutting performance.
