The development of various nontraditional principles to finish the internal surfaces and passages is reviewed. In particular, attention is focused on three relatively mature finishing techniques: abrasive flow machining, internal magnetic abrasive finishing and fluidized bed machining. Their working principles, capabilities and limitations are evaluated accordingly. Finally, the significance of developing internal surface finishing capabilities and the vast potential ahead of this research field are highlighted.

Abrasive flow machining is a nonconventional process used for polishing of metallic components, internal inaccessible cavities or recesses using a semi liquid paste. It was developed to deburr, polish the surfaces having complex geometries and edges by flowing abrasive particles with a visco-elastic nonconductive media over them. Abrasive particle sharp cutting edges remove the material by abrasion mechanism from the workpiece surface. In the recent year, work has been carryout towards the development of abrasive flow machining for achieving the higher material removal and improved surface finish. This method has a unique property of simultaneous improvement in material removal and surface finish. In this paper authors discussed about various recent developments in abrasive flow machining with major objective of improving the productivity of the process.

The application of abrasive suspension flow machining (ASFM) to grind a diesel engine injector nozzle is discussed in this paper. The purpose is to remove the sharp corners of the spray holes and improve the fuel flow through the injector nozzle. The proposed method adopts one-way flow to grind the spray holes for high-efficiency production. Compared with traditional reciprocating flow grinding methods using abrasive pastes, the viscosity of slurry and abrasive concentration of ASFM are lower, better for more smooth flow. To achieve a good grinding performance, it is important to determine proper viscosity and concentration. For this purpose, a design of experiments (DoE) method is adopted. In this paper, an orthogonal test method is combined with a nonlinear regression method to optimize the process parameters. Through a range analysis on experiment results, the optimal process conditions in terms of the grinding efficiency and the grinding quality are determined. Experiment verifications show that the optimized process parameters can significantly improve the ASFM grinding efficiency and grinding quality.
