1. Assessment of shop floor layouts in the context of process plans with alternatives
Abstract Paper aims The paper seeks to compare the performance of three layouts in a make to order (MTO) production system with high product variability. Originality No previous work sought to compare job shop, cellular and virtual cell layouts in an MTO system with high product variability, with just 21 resources, a low amount. The analysis considered m

2. A Comparative Study of Cartesian and Delta 3D Printers on Producing PLA Parts
The additive manufacturing processes emerged at the end of the last century and became popular by low-cost 3D printers. The most used printers work on a cartesian configuration, but recently were launched delta machines. These 3D printers use a more complex control system due to their trajectories generation but may present some advantages over the cartesian

3. The Skateboard Factory: a teaching case on discrete-event simulation
Abstract Real-life applications during the teaching process are a desirable practice in simulation education. However, access to real cases imposes some difficulty in implement such practice, especially when the classes are large. This paper presents a teaching case for a computer simulation course in a production engineering undergraduate program. The motiv

4. Accuracy of intraoral and extraoral digital data acquisition for dental restorations
ABSTRACT The computer-aided design (CAD) and computer-aided manufacturing (CAM) process chain for dental restorations starts with taking an impression of the clinical situation. For this purpose, either extraoral digitization of gypsum models or intraoral digitization can be used. Despite the increasing use of dental digitizing systems, there are only few st

5. Desenvolvimento de um ambiente para simulação da manufatura baseado em features e realidade virtual / Development of environment for simulation of manufacturing based on features and virtual reality
Nowadays with the diversification of products demanded, manufacturing systems have become increasingly complex and with difficult operation. Hardly the person responsible for the manufacturing area has all the information necessary to anticipate the details for their implementation. On the other hand, companies don\ t have the time or resources to test alter

6. Loudness scattering due to vibro-acoustic model variability
The use of numerical simulation in the design and evaluation of products performance is ever increasing. To a greater extent, such estimates are needed in a early design stage, when physical prototypes are not available. When dealing with vibro-acoustic models, known to be computationally expensive, a question remains, which is related to the accuracy of suc

8. Development of a discrete event simulation Kernel for manufacturing systems with 3D visualization / Desenvolvimento de um núcleo de simulador de eventos discretos para sistemas de manufatura com visualização 3D
The need of knowledge and control of the manufacturing environment is continuously growing. Over the last century and the beginning of this, several tools and procedures were designed in order meet those necessities. Among them, simulation is a decision support tool widely used, mainly in the manufacturing industry. Virtual reality can be used in those simul

11. Using advanced CAM-systems for optimized HSC-machining of complex free form surfaces
High speed cutting (HSC) offers the opportunity to significantly reduce machining times as well as to minimize manual rework for complex free form surfaces in the die and mould making industry. To achieve the best results it is also necessary to apply HSC-suitable machining strategies to perform optimal high speed milling operations. This paper presents a me
