STATEMENT OF PROBLEM The conservation of sound tooth structure helps preserve tooth vitality and reduce postoperative sensitivity. Innovative preparation designs, like those for porcelain laminate veneers, are much less invasive than conventional complete-coverage crown preparations. However, no study has quantified the amount of tooth structure removed during these preparations. PURPOSE The ...

Those studies indicated that there was a wide variation in yields of trimmed retail cuts both among all carcasses as well as among carcasses of the same grade. They also showed that variations in yields of cuts were due primarily to variations in conformation and finish. Conformation was positively associated with yield of cuts while finish had the opposite effect. Further analyses of these dat...

The surface finish was extensively studied in usual machining processes (turning, milling, and drilling). For these processes, the surface finish is strongly influenced by the cutting feed and the tool nose radius. However, a basic understanding of tool/surface finish interaction and residual stress generation has been lacking. This paper aims to investigate the surface finish and residual stre...

This study investigates the dry and near-dry electrical discharge machining (EDM) milling to achieve a high material removal rate (MRR) and fine surface finish for roughing and finishing operations, respectively. Dry EDM uses gas and near-dry EDM applies a liquid-gas mixture as the dielectric medium. Experimental studies leading to the selection of oxygen gas and copper electrode for high MRR d...

In the automotive and other industries, the visual appearance of external surfaces is a key factor in perceived product quality. Traditionally, the quality of automotive surface finish has been judged by expert human auditors. A set of 17 fibre-reinforced composite plates was previously manufactured to have a range of surface finish quality, and these plates were previously ranked by three expe...

Fused deposition modeling (FDM) is one of the rapid prototyping technologies that can use plastic material, which can be effectively used for making patterns for investment casting. The surface finish of the investment casting depends upon the surface finish of the pattern. But the surface finish of the parts produced by using FDM is not very good as compared to wax patterns, which are conventi...

Duration of various stages of inflorescence differentiation and hormone levels in apical buds eventually decide the harvest time, flower uniformity and quality of ornamental plants. The progress in inflorescence differentiation process in the chrysanthemum cultivar ‘Jingyun’ can be divided into nine stages. Following short day induction, it took 4d to reach the growing point hypertrophy stage, ...
