Mar-M247, Haynes-230 and Inconel-718 Study of Machining Characteristics for Ni-Based Superalloys on Friction Drilling

摘要:

文章预览

One of the difficulties for Ni-based superalloys application is its manufacturability。Traditional manufacturing process can obtain high strength due to the material characteristic with high strength at high temperature, others like low heat conducting coefficient and process hardening, therefore it could be thought of as a difficult processing material, simultaneously, high temperature drilling could also be resulted in tool wear and broken rapidly, and lead to high process cost。 This study used three Ni-based superalloys such as Mar-M247, Haynes-230 and Inconel-718,applying thermal friction drilling to conduct experiments on the CNC machine using spindle speed and feed rate as process parameters employing Taguchi methods to explore the bush length and internal hole of drilled surface roughness。The results showed that it can generate the longest bush length and best surface roughness for Haynes-230;however Inconel-718 has the largest axial force and worse bush length and surface roughness。
