Research on simulation of superalloy drilling processing based on DEFORM

Nickel-based superalloy is a typical difficult material to be machined. During deep hole drilling of superalloy, high friction force, high cutting temperature, severe tool wear and difficulty in chip removal are easy to be produced. In this paper, based on metal cutting principle and using Deform-3D finite element simulation software, the machining process of Inconel 718 nickel-based superalloy drilled by BTA bit was simulated. The mechanical model of BTA bit, the material model of superalloy and the finite element cutting model was established. The simulation experiment of BTA drilling Inconel 718 was designed, the simulation experiment was carried out by using Deform-3D finite element software, and the distribution of cutting temperature and cutting force under given drilling parameters was obtained.
