バイパス方式によるアブレシブ・サスペンションジェット内の 研磨材濃度の安定化

抄録

The objective of this study is to develop a prototype of polymer- abrasive-water suspension jets (polymer -AWSJ) for micro-cutting of some materials. There are 3-systems as method which supply abrasive into water jet. The bypass system is excellent system for economy and simplicity of system in Abrasive Water Suspension Jets(AWSJs). However, it is demerit the abrasive concentration in jet decrease with jetting time. Experiment for the abrasive concentration in jet is conducted and as the results, experimental results for the abrasive concentration in jet agree with theoretical equation. It is shown that the abrasive concentration in jet is stable by changing the mass flow rate of bypass line.
