Abstract

This paper aims to finish efficiently the surface of internal channels in additively manufactured parts. A novel electrochemical finishing (ECF) method was developed to finish curved channels of 5.8 mm in diameter. The tool electrode required for ECF was additively manufactured simultaneously with the internal channel. The finishing efficiency was significantly high because the electrolysis current flows uniformly at the same time along the channel. Furthermore, the tool electrode was rapidly removed through electrochemical dissolution by reversing the polarity after ECF. The gradient in material removal efficiency along the electrolyte flow ensures the stable removal of the tool electrode.

利用原位通道保形牺牲工具电极对增材制造部件内部通道进行电化学精加工

本文旨在对增材制造零件的内通道表面进行高效精加工。提出了一种新的电化学精加工（ECF）方法，用于精加工直径为5.8 mm的弯曲通道。ECF所需的工具电极与内部通道同时进行增材制造。由于电解电流同时均匀地沿通道流动，因此加工效率显著提高。此外，ECF后通过电化学溶解逆转极性，工具电极被快速去除。材料去除效率沿电解液流动的梯度保证了工具电极的稳定去除。
