CAD/CAM technology (Computer Aided Design / Computer Aided Manufacturing) in the matter of fact helps in design and development of two-dimensional or three-dimensional models and their realization on numerical controlled machines. The key to direct or indirect CAD/CAM dental restorations is the measurement of dental preparation in the mouth or on the plaster die. The aim of this paper is to describe the possibilities and the way of function of different computer aided inspection (CAI) systems as a first part of CAD/CAM systems. Different researchers have presented several approaches of methods for three dimensional (3D) measurement. Today, for chairside dental treatment, only the optical method of measurement has lead to satisfactory results in practice. Laboratory CAD/CAM systems use mechanical and optical technologies for 3D measurement. Optical impression grows as a leader of CAI segment of almost every new CAD/CAM system. The most important properties of 3D scanners are: accuracy, volume and speed of measurement and ergonomy of instrument. .

Advanced products demand advanced CAD, CAM, and digital engineering systems. This is the main consideration in this special issue. It is well understood by all manufacturers nowadays that CAD, CAM, and digital engineering systems behave as “Hidden factories” of engineering information processing and are indispensable to the accomplishment of their daily tasks. No products can be planned, designed, machined, and assembled without these hidden factories. The history of CAD/CAM goes back nearly five decades, yet the technologies are still immature: a lot of technical issues remain to be solved because new materials and structures have been introduced in products, new manufacturing technologies have been utilized, and new social needs, such as the need for ”eco-X” or ”human-oriented” products, have grown along with the dramatic changes in society. New high-performance computing resources, such asWeb-based computing or GPUcomputing, have also become available for implementation in these systems. Thirteen technical papers in this issue tackle these challenges, proposing solutions from utilizing technologies, including computer-aided geometric design (CAGD), CAD, CAE, CAPP, and CAM, as well as novel human interfaces for these systems. Some of the papers, revised and extended in response to the editors’ invitations, are versions of works presented at the Asian Conference on Design and Digital Engineering 2012 (Niseko, Japan) and 2013 (Seoul, Korea). In addition, two well-organized review papers in this issue provide informative and comprehensive surveys of aesthetic curve and surface design in CAGD and knowledge structuring and logic reasoning in CAPP, respectively. They include rich lists of references which will help the readers to quickly gain an overview of the current status and future research directions of these fields. Finally, the editors sincerely thank all the authors and anonymous reviewers for their devoted work, as they made this special issue possible. We expect that it will encourage further research on advanced CAD, CAM, CAE, CAPP, and digital engineering systems.

Contemporary technological development (CAD/CAM/CAE, VR, AR, MR) made conventional methods of Descriptive and Constructive Geometry uncompleted. Application and use of new technologies in Constructive geometry requires educational process with the aim to have complete knowledge of all fields that belong to this area. The aspect and results research shows that knowledge acquired in this way by using new technology, develops students' skills that are very important in senior years of studies, particularly in the field of engineering design. Interactive dynamic 3D geometry could not be achieved by conventional ways of studying. The use of modern technology should enable expanding the fields of research as well as preservation of the theoretical knowledge of descriptive geometry.

The teaching of the traditional mold courses focus on the illustration of theoretical knowledge. Therefore, associating the design, evaluation, and manufacture links as a whole is difficult. Students cannot shape system knowledge, thereby making the study difficult. In addition, traditional teaching cannot meet the current enterprise needs of talents who have mold CAD/CAE/CAM technology. This study presents a teaching method that applies CAD/CAE/CAM technology to mold teaching. First, the positive effects of these technologies on the mold design and manufacturing process are introduced. Thereafter, lamp cover is used as an example to establish a series of computer-aided teaching development processes using existing software for mold design, mold flow analysis, and machining simulation. Lastly, survey results demonstrate that the effects of the proposed teaching method are better than the traditional method. Moreover, students and enterprises are substantially recognized in this teaching method.

In this paper, a comparison between CNC manufacturing and Rapid Prototyping technology (FDM – Fused Deposition Modeling process), applied for a cam fabrication, is presented. In the products development area, a substantial support is offered by models, as intermediate between product configuration and technology design. The CAD/CAM/CNC technology is a widely used technique for creating prototypes, as well as production parts, using a subtractive type material-removal procedure from a semi-manufactured article. The rapid prototyping (RP) technologies are additive processes, where the part is built up layer by layer until done, directly from the 3D CAD model, within the precision limits of the chosen process. Similarities and differences between these two coexisting computer driven prototyping processes, the subtractive CNC 3 – axes milled part production and the additive RP/ FDM technique, are pointed out for a disk cam manufacturing as sample part.

Advances in computer-aided design (CAD) / computer-aided manufacturing (CAM) technologies and their ease of application enabled the development of novel treatment concepts for modern prosthodontics. This recent paradigm shift in fixed prosthodontics from traditional to minimally invasive treatment approaches is evidenced by the clinical long-term success of bonded CAD/CAM glass-ceramic restorations. Today, defect-oriented restorations, such as inlays, onlays, and posterior crowns, are predominately fabricated from glass-ceramics in monolithic application. The variety of CAD/CAM ceramic restorative systems is constantly evolving to meet the increased demands for highly aesthetic, biocompatible, and long-lasting restorations. Recently introduced polymer-infiltrated ceramic network CAD/CAM blocks add innovative treatment options in CAD/CAM chairside 1-visit restorations. The material-specific high-edge stability enables the CAD/CAM machinability of thin restoration margins. Full-contour zirconia restorations are constantly gaining market share at the expense of bilayered systems. Advancements in material science and bonding protocols foster the development of novel material combinations or fabrication techniques of proven high-strength zirconia ceramics. CAD/CAM applications offer a standardized manufacturing process resulting in a reliable, predictable, and economic workflow for individual and complex teeth-supported restorations. More evidence from long-term clinical studies is needed to verify the clinical performance of monolithic polymer-infiltrated ceramic network and zirconia teeth-supported minimally invasive and extensive restorations.

Subject. Modern digital technologies allow us to significantly automate the process of creating prosthetic devices. First, digital images of the patient's dental rows are obtained, then the future prosthesis is virtually modeled and made using a subtractive method using CAD/CAM, or an additive method using a 3D-printer. Objective ― conducting a comparative assessment of the time spent by an orthopedic dentist and a dental technician for the production of artificial dental crowns obtained using digital and traditional technologies. Methodology. The patients were divided into four groups according to the method of manufacturing temporary artificial crowns-from a composite material Protemp 4 using a silicone key, using the CAD/CAM-system KaVo ARCTIC from polymethylmethacrylate VITA CAD-Temp multicolor, using a 3D-printer Asiga Max UV from a biologically compatible photopolymer material NextDent C&B MFH and a laboratory method of cold plastic polymerization. For statistical analysis of the results obtained, the Kraskel―Wallis H-test and the Mann―Whitney W-test were used. In total, 40 medicinal artificial crowns were made, 10 in each group. Results. Based on the data obtained, it was found that for the manufacture of a dental artificial crown using the 3D-printer Asiga Max UV dentist orthopedist and dental technician should spend 38.8 ± 4.104 minutes, using CAD/CAM KaVo ARCTICA-29.0 ± 3.162 minutes, using the laboratory method ― 71.6 ± 4.502 and using a silicone key ― 62.8 ± 5.613. Conclusions. The obtained data allowed us to conclude that the production of a temporary artificial crown with the use of modern digital technologies (CAD/CAM-systems, intraoral laser scanning and 3D-printer) requires less time compared to traditional methods of manufacturing a prothesis (p<0.0166667).

Regulation of the Ca2+-activated Cl− channel TMEM16A by Ca2+/calmodulin (CAM) is discussed controversially. In the present study, we compared regulation of TMEM16A by Ca2+/calmodulin (holo-CAM), CAM-dependent kinase (CAMKII), and CAM-dependent phosphatase calcineurin in TMEM16A-overexpressing HEK293 cells and TMEM16A expressed endogenously in airway and colonic epithelial cells. The activator of the Ca2+/CAM-regulated K+ channel KCNN4, 1-EBIO, activated TMEM16A in overexpressing cells, but not in cells with endogenous expression of TMEM16A. Evidence is provided that CAM-interaction with TMEM16A modulates the Ca2+ sensitivity of the Cl− channel. Enhanced Ca2+ sensitivity of overexpressed TMEM16A explains its activity at basal (non-elevated) intracellular Ca2+ levels. The present results correspond well to a recent report that demonstrates a Ca2+-unbound form of CAM (apo-CAM) that is pre-associated with TMEM16A and mediates a Ca2+-dependent sensitization of activation (and inactivation). However, when using activators or inhibitors for holo-CAM, CAMKII, or calcineurin, we were unable to detect a significant impact of CAM, and limit evidence for regulation by CAM-dependent regulatory proteins on receptor-mediated activation of endogenous TMEM16A in airway or colonic epithelial cells. We propose that regulatory properties of TMEM16A and and other members of the TMEM16 family as detected in overexpression studies, should be validated for endogenous TMEM16A and physiological stimuli such as activation of phospholipase C (PLC)-coupled receptors.

One of the major barriers to the integration of CAD, CAPP and CAM is insufficiency and incompatibility of product model data among various application systems. This paper presented an effective approach to achieve integrated process planning with CAD and CAM under a product data management environment based on 3D product models. The system architecture and the processes of an integrated process planning system (3D-IPP) were constructed using feature information and specific CAD/CAPP/CAM integration technologies based on feature. A feature-based product information model is designed as the information source for the 3D-IPP. A feature-based integrated process planning method was developed based on group technology, intelligent decision-making algorithms and parametric operation templates in numerically controlled (NC) programming. The procedures of intelligent process route planning and parametric NC operation planning were addressed. The 3D-IPP system and its implementation provide an effective solution to strive for complete information sharing among application systems of CAD, CAPP and CAM.

The Computer Aided Design and Computer Aided Manufacturing are the modern innovative technology in garments manufacturing like all other manufacturing sectors. Garments CAD is specially used for pattern designing and marker making. On the other hand CAM is used for fabric cutting and other manufacturing sections. Before implementing those new technologies, manual system was widely used in garments sector. In recent time some large garments factories of Bangladesh are starting to adopt CAD and CAM technology. Beside that a huge number of medium and small size factories are using manual system yet. This paper presents a feasibility study of CAD and CAM technology in above mentioned different size factories in Bangladesh. The Study is carried out in respect of production procedure, required man power, production/hr, product quality, production efficiency, and production cost. The practical investigation and data shows the scenario that all types of garments industries are not capable to use CAD & CAM and also not even profitable for them.

Aerosol-based direct-write refers to the additive process of printing CAD/CAM features from an apparatus which creates a liquid or solid aerosol beam. Direct-write technologies are poised to become useful tools in the microelectronics industry for rapid prototyping of components such as interconnects, sensors, and thin film transistors (TFTs), with new applications for aerosol direct-write being rapidly conceived. This paper aims to review direct-write technologies, with an emphasis on aerosol-based systems. The different currently available state-of-the-art systems such as Aerosol Jet CAB-DW, MCS, and aerodynamic lenses are described. A review and analysis of the physics behind the fluid-particle interactions including Stokes and Saffman force, experimental observations, and how a full understanding of theory and experiments can lead to new technology are presented. Finally, the applications of aerosol direct-write for microelectronics are discussed.
