1.1 History Sheet metal operations have been in existence since 8000 B.C. (Fries-Knoblach, 1999). Due to its long history, sheet metalworking is, unfortunately, often seen as archaic and uninteresting. That metal sheets can be transformed with the aid of robust machines into fancy consumer products with tight tolerances is inconceivable to many. Yet, sheet metal operations are used for producin...

Rapid Manufacturing (RM) is increasingly becoming a viable manufacturing process due to dramatic advantages that are achievable in the area of design complexity. Through the exploration of the design freedom, this paper introduces the concept of manufacturing textiles for potential smart and high performance textile applications. This paper discusses the current limitations associated with the ...

Introduction: Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) are the latest achievements of Prosthodontics and Restorative Dentistry. The aim of this research is to help make appropriate decision whether to use this technology in Iran. Methods: Studies were included in this review that compared Dental CAD/CAM with conventional restorativ...

Background: This study aimed to assess the fracture resistance of zirconia restorations fabricated with rapid layer (RL group) technique and zirconia computer-aided design/computer-aided manufacturing (zir/CAD/CAM) system (ZC group). Methods:This study evaluated 30 all-ceramic crowns in two groups of 15. After fabricating the metal dies and scanning them ...

Abstract Background and Aim: High chipping rates of the veneering porcelain of zirconia ceramic restorations have been reported in clinical studies. Thus, the shear bond strength (SBS) between the zirconia core and veneering porcelain requires investigation. Materials and Methods: In this in-vitro study, at first, using a computer-aided design/computer-aided manufacturing (CAD/CAM) machine, 1...

Production systems design is critical to achieving manufacturing performance and objectives. Although generic approaches to this design are available they may not be able to objectively address specific manufacturing configurations. Here it is argued that product oriented manufacturing (POM) organization offers advantages in relation to the function oriented one. Based on this, a methodology sp...

The unique methods of computer-aided design/computer-aided manufacturing (CAD/CAM) dentistry provide an exciting alternative to the traditional laboratorycreated porcelain veneers that have been a proven solution for smile makeovers. Design techniques have continued to evolve, with new three-dimensional (3D) graphics software that makes the process more intuitive and easier to understand. Impro...
