Description

Maraging steels are used for jet engine of aircrafts and rockets. Maraging steels are superior high-temperature properties and they are also known as difficult-to-cut materials. There is a driven rotary cutting as a new machining method for difficult-to-cut materials. Driven rotary cutting is machining method used rotating tool with multi-tasking lathe. The cutting heat and the tool wear are distributed all around the cutting tool due to rotating tool; therefore tool life is expected to increase. In this paper, driven rotary cutting was conducted for the maraging steel. Influence of cutting conditions on tool wear was investigated. As a result, we found that cutting conditions have optimal conditions that decrease the tool wear. In addition, tool life test was conducted. As a result, driven rotary cutting achieved efficiency 11 times or more of conventional turning.
