Honing is a finishing method by means of rotary motion and alternate motion between the honing stones assembled on the honing head and the workpiece. In honing process, the honing stone status is varying all the time and plays important role in cutting property. This paper analyzes the wear mechanism and the cutting property by cylindrical honing experiments. The wear mechanism is analyzed by the topography obtained by a microscope and the cutting property was investigated by two factors: material removal rate and honing force.

To improve low lapping efficiency of silicon nitride balls in conventional lapping process, fixed abrasive lapping technology for ceramic balls is investigated in this paper. Diamond abrasives and photosensitive resin are used to fabricate the fixed abrasive plate. The lapped ball surface is observed with microscopy to identify the dominant wear mechanism. The results show that the material removal rate of the fixed abrasive lapping is about 20 times of that of conventional free abrasive lapping process, and the roughness is close to the conventional one. The experimental results indicate that the fixed abrasive lapping technology is a promising process to instead of conventional free abrasive lapping process for ceramic balls in rough and semi-finishing process.

Abrasive Free Polishing (AFP) is a polishing technology without abrasives and widely employed in copper-base semiconductor fabrications. This paper investigates the effect of passivants, added to the slurry, on the material removal rate (MRR) and the non-uniformity (NU) via experiments. Two kinds of passivants, Benzotriazole (BTA) and citric acid (CA) are added to the slurry for the experiments. Experimental results showed that the MRR increases when polishing pressure increases while NU decreases at the same time. Both MRR and NU tends to increase when rotational speed increases, though MRR and NU at 40 rpm are lower than that at 30 and 50 rpm in the slurry with CA. Experimental data also showed that AFP using the slurry with CA performs better than that with BTA.

Lapping is a finishing process used especially for removing the material, achieving finer surfaces, correcting minor imperfections and maintaining close tolerances. This process may takes place due to the relative motion between the work material, slurry and lapping plate. This study is done by conducting a series of experiments based on taguchi design of experiments and calculating material removal rate and surface roughness. This study explains about effect of the parameters on material removal rate and surface finish. The final step of this process is to find out the optimum combination of process parameters to determine the material removal rate and the surface finish.

High temperature Fiber Metal Laminate – Titanium/Graphite (Ti/Gr) is an advanced material system, developed to meet the high temperature requirements in aerospace applications. High specific strength and stiffness of composite core along with its protection from aggressive environment by tough titanium alloy sheets qualify FMLs for a promising alternative material where metallic and composites overcome each other's limitations. However, industrial employability of this three phase system is often limited by the machining challenges posed by the difference in material removal mechanisms of Titanium alloy, PIXA thermoplastic polyimide resin and graphite fibers. An experimental investigation was conducted to evaluate the machinability of 1 mm thick Ti/Gr laminate sheets through Abrasive Waterjet (AWJ) machining process in terms of kerf characteristics and material removal rate. The parametric influence of AWJ operating variables on machining performance was studied by systematically measuring operating variables (traverse speed and Abrasive flow rate) using fully crossed Design of experiment (DOE) scheme, and statistically analyzing using ANOVA (Analysis of variance) technique. Empirical models were developed to quantify these effects and predict the influence of process parameters on material removal rate, kerf taper, entry damage width and overcut in straight cutting of Ti/Gr sheets.
