Objective To analyze the impact of color a resin composite cement (RCC) on optical properties different computer-aided design and manufacturing (CAD/CAM) ceramics. Materials methods Specimens (N = 220, thickness: 0.9 ± 0.03 mm) were fabricated from: leucite (Initial LRF Block/IPS Empress CAD), lithium disilicate (Amber Mill/IPS e.max metasilicate (Celtra Duo), alumina silicate ceramic (n!ce) in...

globally distributed manufacturing is possible. Virtual corporations can be established involving participants from around the world. Design, production, and assembly can occur wherever is most convenient and cost-effective for the enterprise. Developments in CAD/CAM, including advances in product data models and international standards, have made this possible. See COMPUTER PROGRAMMING; DIGITA...

The growing sophistication of applications continually pushes the design and manufacturing of digital systems to new grades of complexity. Computer aided design education deals with the computer as a tool to help perform the various tasks that comprise the design process of digital systems. In order to understand the capabilities of that tool, one has to study how the tool is used in the differ...

Sheet metal is commonly used in the automotive industry. The requirements for developing approaches for manufacturing automotive panels have become increasingly important as carmakers seek to shorten their time to market. However, designing and manufacturing mold dies for automotive sheet metal panels is time-consuming as several processes use the trial-and-error method. The die design period f...

Abstract Advances in manufacturing technologies and computational engineering are key enablers for optimized designs necessary product performance improvements. Amongst other technologies, particularly Additive Manufacturing (AM) is pushing the envelope of feasible design complexity challenging engineers as well their Computer-Aided Design (CAD) tools. The research field (DfAM) provides an exha...
