“…The investigation showed that median and radial cracks did not appear and hence were not the cause of fracture as usually thought. Chen et al [15] investigated and analyzed theoretically, the factors influencing the surface quality of brittle materials, during ultra-precision grinding. Grinding experiments were also carried out to confirm the outcome of theoretical analysis, for the brittle materials.…”

“…Liao and Chen [3] used back-propagation neural networks to model and optimize the creep-feed grinding of alumina with diamond wheels. Chen et al [4] investigated and analysed the factors that influence the surface quality of brittle materials during ultra-precision grinding. Their results showed that the abrasive grain size of the diamond wheel has a significant influence on the surface quality with the wheel speed and feed rate only being of secondary importance.…”

The selection of optimum machining conditions, during ceramic grinding, is of great concern in manufacturing industries these days. The increasing quality demands, at higher productivity levels, require the ceramic grinding process to be executed more efficiently. Specifically, the material removal rate needs to be maximized while controlling the surface quality. Despite extensive research on the ceramic grinding process, determining the desirable operating conditions in industrial setting still relies on the skill of the operators and trial-and-error methods. In the present work, an attempt has been made to optimize the grinding conditions for maximum material removal rate using a multi-objective function model, with surface roughness and tangential grinding force as user definable constraints. Experiments were carried out to study the effect of various parameters namely the depth of cut, table feed, grit size, and grit density on the surface roughness and tangential grinding force. Mathematical models were developed using the experimental data considering only the significant parameters. In order to optimize the grinding conditions for maximum material removal rate, a genetic algorithm (GA) code was developed. The manufacturer’s constraints, based on the functional requirements of the components for maximum production rate, have been included in the GA code.

In order to machine high accuracy Potassium Dihydrogen Phosphate (KDP) crystal part, the indentation experiments are carried out with various loads and various orientation angles. The experimental results show that the critical condition of brittle-ductile transition of KDP has strong anisotropy. Therefore, the influence factors on the surface quality of crystal KDP was discussed, it is shown that influences of the tool's geometry parameter, feed rate and Nominal depth of cut etc on the surface quality of KDP are main. Afterwards the cutting experimental study on crystal KDP material is carried out. The experimental results show that the super-smooth surface quality only can be obtained while KDP is ultra-precision machined in ductile mode.
