The mathematical model of forming integral fin tubes by the double ploughing method is established. The relationship between the geometric variables that characterize integral fin tubes and the cutting data, tool geometry parameters is revealed theoretically. Based on this model, the optimal fin parameters for enhanced the heat transfer can be obtained. The theoretical analysis and the experiment results indicate that for a certain tool, the fin height and mean fin thickness increase with the increase of...

A new method of machining integral fin tubes (IFT), chopping extrusion technique, was presented. From the experimental observation, it was revealed that the processing of forming a unity of fins can be divided into three stages: chopping, extrusion and forming. It was shown by experimental results that there are four factors playing chief roles on processing of fin such as geometric parameters of cutting tool, depth of extrusion, feed and speed of chopping extrusion. For a certain cutting tool, a limit...

A new method of machining integral fin tubes (IFT), chopping extrusion technique, was presented. From the experimental observation, it was revealed that the processing of forming a unity of fins can be divided into three stages: chopping, extrusion and forming. It was shown by experimental results that there are four factors playing chief roles on processing of fin such as geometric parameters of cutting tool, depth of extrusion, feed and speed of chopping extrusion. For a certain cutting tool, a limit feed was brought up with a definite extrusion depth under given chopping extrusion speed. Only given proper parameters could continuous process of fin forming be carried out and the optimal shape of fins be obtained. Production costs will be reduced and productivity increased by employing this machining method because of easy performing and direct forming of fins. [
