MANUFATURA ENXUTA: a utilização de princípios e ferramentas do Lean para a eliminação de desperdícios em um processo de inserção de componentes eletrônicos

Abstract

In the following work, Lean Manufacturing, or lean manufacturing, will be the main point of analysis. Officially created in the early 1980s, Lean is based on the Toyota Production System (TPS), which was coined during the 1950s and 1960s, by Taiichi Ohno. TPS preaches the reduction of waste and losses, in order to reach the ideal state, where there are no losses in a process. In this ideal state, there would be only steps that would add value to a product from the customer's point of view. This elimination is achieved through the application of practices and tools throughout the process and more importantly, Lean seeks a change in the mentality of each participant in the production process. The transition from traditional to lean thinking is extremely important for the success of the program. It is worth remembering that such a gain in the process does not occur immediately, since lean manufacturing works a lot with the observation and planning of activities. Therefore, it is common to say that Lean practitioners must have a culture change, so that their culture be for change. Taking as an application example a reactor manufacturing process, in which electronic components are inserted, this monograph will report how principles, concepts, practices and tools can help to reduce the so-called seven wastes of the Zem methodology (over-processing, over-production, stock, transport, waiting, handling and defect) and from this reduction, improve the productivity of the automatic insertion sector.
