Abstract: Extrusion honing (EH) process is employed to deburr, polish or radius surfaces and edges by flowing a silicone abrasive medium over the surface to be finished. Such finishing operations play a vital role in producing method of machine components. EH could be a time consuming process, even though EH is employed within the industries particularly in the case of finishing complicated internal and external shapes. In EH process, medium is the key elements that control the finishing process. Though, commercially available abrasive medium are very expensive and its affordability is an issue, especially for price sensitive industries. Inconel (718) material is widely used in aerospace industries, hence it has been chosen for the characteristics study through EH process. In the present study silicone and silicon carbide abrasive is chosen as the medium. Surface roughness parameters are used as a means of determining the performance of the EH process. The main experimental parameters are the abrasive concentration, number of passes and keeping constant hydraulic pressure. It is observed that the roughness parameters Ra, Rz, Rt and Rpk decreases after 15 passes and 25% of volume fraction of abrasive concentrations were used for the experimentation.
