Abstract

The colleagues of the author of this paper applied the concept of 'contact' in differential geometry into the machining of the sculptured surface (Chun et al., Math Theor Appl, 23(3):105-108, ) and presented the second-order contact principle of the machining of complicated surfaces, using the circumference circle of the flat-end mill to sweep the curved surface instead of ball-end mill. But only mathematical deductions were presented in the paper. This paper proves that it is a highly effective method. Compared with other references, the theory of this paper is more restricted, and the method of this paper is suitable to the primary analytic geometry and the simulation surface of the numerical geometry as well. With definite procedure of calculation, the equations in this paper are easily solved. [ABSTRACT FROM AUTHOR]

Abstract

Objective: To evaluate the effect of viscosity and type of grooves on surface detail reproduction of elastomeric impression materials. Methods: Express putty/light-, Impregum medium- and heavy/light-bodied and Aquasil medium- and putty/light-bodied elastomeric impression materials were chosen for this study. Five impressions were made using a cylindrical aluminum reference block with U- and V- shaped grooves and to produce 35 master dies. Each master die was immersed in distilled water at 370 C for 5 minutes prior to the impression making on moist surfaces. Surface topography of the dies and impressions were captured using Alicona Imaging System. The mean difference in depth between the master dies and its corresponding impressions were analysed using two-way ANOVA, p=.01. Results: The lowest mean difference in depth for U- and V-shaped grooves was obtained from the Express putty/light group. The highest mean difference in depth for U- and V-shaped grooves was obtained from Impregum medium, Aquasil medium, Impregumâ??Â? heavy/light and Impregum heavy/light groups respectively. Two-way ANOVA indicated that there was a significant difference in the effect of materials (p < .01) and grooves (p < .01). Conclusion: Express putty/light-bodied elastomeric material produced the best surface detail, and U-shaped groove showed better surface detail reproduction than V-shaped groove. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down.
