The article deals with the use of CAD / CAM software Autodesk Inventor in the production of the shaft. CAM programming is very important in the field of engineering because it speeds up the process of manufacturing parts and enables the production of their complex shapes. The article describes the programming of turning, milling, drilling and threading of the shaft. The programming was followed by the production of the shaft. The manufactured shaft met the dimensions according to the technical documentation and was subsequently used in the assembly.

Great emphasis has been attached to the achievement of productivity and producibility benefits through the application of computer-aided design and computer-aided manufacturing (CAD/CAM) technologies. To ensure the achievement of these benefits, it is important that the end user have appropriate software and be able to use it to his advantage. The proper procurement, customization, installation, training, and implementation of software can play a significant role in the effectiveness of CAD/CAM.

Abstract Background Contemporary dentistry is advancing toward computer-aided design/ computer-aided manufacturing (CAD/CAM) technology. But the budding dentists are unaware about the advancement. This survey aims at detecting the level of awareness among the undergraduate students and then correlating those results to modify the future curriculum. Objective The study aims (1) to assess the awareness among the dental undergraduate students and (2) to correlate the level of awareness among the third years, final years, and interns. Sample Selection Study sample consist of 300 students (third year students, final year students, and interns) of A. B. Shetty Memorial Institute of Dental Sciences, Mangalore, Karnataka, India. The information of the survey was collected with the help of a questionnaire. Results More than 70% of the students were aware about the basic functioning of CAD/CAM unit and approximately 74% of the students were unaware about the materials used to fabricate the prosthesis using CAD/CAM technology.

Computer-aided manufacturing (CAM) software is used to develop a process plan, which consists of an operations list, tool paths, tooling, process parameters, and depending on the system, material handling operations. Upon completing the development of a process plan, setup sheets are generated for the personnel involved in the setup, production, testing, and product validation activities for a product. Typically, this documentation is in a hardcopy format, or is a static electronic document, and the direction of the communication is unidirectional — from the process planner to the support personnel. With the ubiquitous communications tools available to individuals today, a more sophisticated approach should be taken to transmit, store, and communicate changes to and from the shop floor. Presently, standard setup documentation consists of the project information utilized for the developed process plan. Pictures such as screen captures of the tool path, virtual verification images, and physical elements such as specialty tools may be included. However, modifications are made continuously to improve the cycle time, quality, or to adjust for other product or process changes. This research focuses on the development of interactive setup sheets that utilize existing desktop CAD/CAM software and mobile technologies, with the potential for leveraging the advantages of manufacturing cloud computing. Videos, links to additional documentation, and the ability to edit a subset of process parameters such as a tool diameter are incorporated. The operator is able to physically change tools or other key process setup information, and then send the information to the CAM system in order to regenerate the updated tool paths and documentation. Complementing the flexible, agile, and reconfigurable paradigms is the communication flexibility provided by fast wireless networks along with, cloud computing resources that can accessed with mobile devices, which are ubiquitous in today’s society. This technology that has not yet been heavily employed in the manufacturing environment, and research leveraging these new tools need to be explored.

Background: High correction bracing is the most effective conservative treatment for patients with scoliosis during growth. Still today braces for the treatment of scoliosis are made by casting patients while computer aided design (CAD) and computer aided manufacturing (CAM) is available with all possibilities to standardize pattern specific brace treatment and improve wearing comfort. Objective: CAD / CAM brace production mainly relies on carving a polyurethane foam model which is the basis for vacuuming a polyethylene (PE) or polypropylene (PP) brace. Purpose of this short communication is to describe the workflow currently used and to outline future requirements with respect to 3D printing technology. Method: Description of the steps of virtual brace adjustment as available today are content of this paper as well as an outline of the great potential there is for the future 3D printing technology. Results: For 3D printing of scoliosis braces it is necessary to establish easy to use software plug-ins in order to allow adding 3D printing technology to the current workflow of virtual CAD / CAM brace adjustment. Textures and structures can be added to the brace models at certain well defined locations offering the potential of more wearing comfort without losing in-brace correction. Conclusions: Advances have to be made in the field of CAD / CAM software tools with respect to design and generation of individually structured brace models based on currently well established and standardized scoliosis brace libraries.

Introdução: O sistema CAD CAM (Computet Aided Design/Computer Aided Manufacturing) representa um grande avanço para a odontologia restauradora e protética. Inserido na odontologia na década de 70, sofreu constantes aperfeiçoamentos, e recentemente tem sido empregado na confecção de próteses totais. O presente trabalho busca discutir o uso desse sistema para confecção de próteses totais, além de apresentar as técnicas para tal, vantagens e desvantagens e comparar brevemente com a técnica manual. Metodologia: Revisão discutida da literatura, realizada por meio da análise de estudos de casos clínicos, revisões narrativas da literatura, teses e dissertações, que estivessem na língua inglesa ou portuguesa. Foram utilizadas as bases de dados PubMed e LILACS, utilizando os descritores: “CAD CAM “, “complete denture” e “digital”. O operador booleano “AND” foi utilizado associado aos descritores. Foram selecionados 32 estudos para análise de 1994 a 2021. Resultados: O sistema CAD CAM é composto por: scanner, software e a unidade CAM fornecendo o escaneamento de um molde, modelo ou da própria cavidade oral. A obtenção das relações intermaxilares geralmente é feita através do método convencional com posterior escaneamento dos dados para manipulação e planejamento da futura prótese no software. Melhor retenção, resistência a fratura, menor contração de polimerização, liberação de monômeros, porosidade e tempo de cadeira, são benefícios dessa técnica. Conclusões: A confecções de próteses totais digitais apresenta futuro promissor na odontologia, todavia, limitações referentes ao escaneamento, relações intermaxilares e acessibilidade, são uma realidade. Faz-se assim, necessário mais estudos sobre tal temática.
