Influência de software de otimização de corte no rendimento de serraria da região sudoeste paulista

This study aimed to analyze the increase of yield provided by a software optimization cutting in a pine sawmill, located at southwest region of São Paulo, city of Itapeva. First were measured 10 logs that were processed by conventional sawing system by measuring the volume of products in the process output. Then using a cutting optimization software, that generated cuts diagrams, 10 logs, from 25 to 26 cm diametrical class, were processed by sawing system optimized. For the conventional sawing, the value found to yield was 41.80%, whereas for the unfolding optimized showed the value of 61.79%, resulting in a difference of 19.99%. This study shows that there is room for significant improvement of performance in sawmills sawing with the use of optimization software as the employee at work

Estudo de caso de controle estatístico de processo: levantamento da variação de espessura de tábuas de pinus

This graduate work approaches the study of Statistical Process Control - SPC, in a stage production of an industrial frame, aiming to use the tool of statistical process control (SPC) to assess the process capability. Where the process needs improvement as well not meet the specifications. Assessing the needs that the company needs to improve quality management, and the difficulties they present during the implementation of the CEP. The present study is to use the method of case study. The results are presented through study, and checking the capacity and stability of the process using control charts XbarraR. The process demonstrated the need for improvements in process and quality management. At the end of the work are presented suggestions for improving the quality system of the company

Análise do consumo de energia elétrica e da eficiência energética em uma indústria de processamento de madeira

In the industries of wood processing (sawmills), where timber is sawn in equipment such as band saws, circular saws, trowel, thicknessers, among others, that mechanically transform this resource and use of electric motors, which are not unusually poorly scaled working or overloaded, often a factor that is not found in these industries and has fundamental importance in the production process is energy efficiency that is achieved by both technological innovation and through all the practices and policies that aim to lower energy consumption, lowering energy costs and increasing the amount of energy offered no change in generation. For both during the design of an electrical installation, both overall and in various sectors of the installation, investigations are necessary, considerations and uses of variables and factors that put into practice the theme of energy efficiency. Therefore, in this paper, these factors were calculated and analyzed for a wood processing industry (sawmill) in the municipality of Taquarivaí - SP, namely: active power, power factor, demand factor and load factor. Where they were small in relation to the literature, these events that occur when devices are connected at the same time and due to the conditions of processing the wood, where the engines have large variations in electricity consumption during the unfolding of the same, due to efforts with the load and idle moments between each machining operation in the equipment
