  • Issues Related to the Use of Sprutcam in Wood Processing
    Annals of the University of Oradea, Fascicle: Environmental Protection Vol. XXXI, 2018 Analele Universităţii din Oradea, Fascicula: Protecţia Mediului Vol. XXXI, 2018 ISSUES RELATED TO THE USE OF SPRUTCAM IN WOOD PROCESSING Derecichei Laura*, Lucaci Codruţa*, Cheregi Gabriel* *University of Oradea, Faculty of Environmental Protection, 26 Gen. Magheru St., 410048 Oradea, Romania Abstract Computer-assisted use is a step forward in designing technically and economically competitive technological processes in the wood industry. Preparing CNC machining programs for parts with three-dimensional complex surfaces would be extremely difficult without the techniques mentioned above. CAD / CAM products offer the possibility to develop processing programs for existing equipment on the market. These software packages allow, in addition to generate the tool center trajectory, a complex simulation of the machining process in which the movements of the machine elements required in the manufacturing process can be traced. An important branch of CAM methods is numerical control. This is a technique whereby the operations of a machine can be controlled by means of a program's instructions: cutting, milling, drilling, various surfaces of the blank can be carried out in such a way that at the end of the program the piece desired. The simulation of the CNC 5-axis machining operation was carried out with the SPRUTCam program, which was obtained from the "Hermann Oberth" Engineering Faculty of Sibiu in the Department of Machinery and Industrial Equipment. Key words: SPRUTCAM, CAD-CAM ,CNC,. wood INTRODUCTION Steps to get the NC code into SPRUTCAM Processing a complex wood piece on a CNC machine involves generating a CN code that contains, in a numerically coded form, the commands for moving the machine and / or tool trays on the trajectories required to obtain the shape of the finished part.(Ganea, M., 2010, Ganea, M., 2010, Ganea, M., 2000, Jain, A.

The idea on fabrication of low cost CNC Router came forward to reduce the cost and complexity in CNC systems. This paper discusses the development of a low cost CNC router which is capable of 3-axis simultaneous interpolated operation. The lower cost is achieved by incorporating the features of a standard PC interface with micro-controller based CNC system in an Arduino based embedded system. The system also features an offline G-Code parser and then interpreted on the micro- controller from a USB. Improved procedures are employed in the system to reduce the computational overheads in controlling a 3-axis CNC machine, while avoiding any loss in overall system performance. I. INTRODUCTION: In modern CNC systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a post processor, and then loaded into the CNC machines for production.

    Percursos de maquinagem 2D: mesa CNC e robô industrial Luís Carlos Santos Oliveira Dissertação do MIEM Orientador: Manuel Romano dos Santos Pinto Barbosa Coorientador: Paulo Augusto Ferreira de Abreu Mestrado Integrado em Engenharia Mecânica Especialização de Automação Junho de 2018 ii Percursos de maquinagem 2D: mesa CNC e robô industrial À minha família iii iv Percursos de maquinagem 2D: mesa CNC e robô industrial Resumo A globalização é responsável por diversas modificações no mundo, destacando-se o avanço tecnológico acelerado e consequentemente uma intensa robotização na produção industrial. No caso particular da maquinagem, a utilização de robôs industriais é também uma área em crescimento. A sua grande flexibilidade e relação custo/benefício torna-os uma solução complementar a máquinas CNC, que têm um espaço de trabalho limitado e custo elevado. No entanto, são ainda muitas as barreiras a ultrapassar para que os robôs assumam um papel preponderante na execução de operações de maquinagem, dado que apresentam baixa exatidão e rigidez e, ainda, limitação de software específico. Ao longo deste trabalho é realizada uma análise comparativa de parâmetros e funções de programação, disponíveis em dois sistemas distintos: mesa XY comandada por CNC e robô industrial. Um dos objetivos principais é identificar as implicações da utilização destas funções na execução de percursos de maquinagem, do tipo fresagem e respetivas velocidades de avanço. Igualmente pretende-se também avaliar a facilidade e eficiência da programação em cada sistema. A mesa XY é comandada por um CNC Fagor® 8055M e o robô industrial é um robô ABB® IRB2400, usando apenas como ferramenta um dipositivo para traçar os percursos (caneta) numa folha de papel.
