Melhoria da qualidade aplicado a um processo de usinagem em uma fábrica do polo de duas rodas

Abstract

In recent years, machining technology has undergone profound changes, the main objective of which is to increase productivity and guarantee quality. This is achieved through the use of Computer Numerical Control (CNC) machines to automate the process. The present work has the general objective of investigating proposals for the improvement of quality in a given integrated manufacturing process (machining). The survey was conducted at a company in the motorcycle production industry located in Manaus. The classification as to the means addresses, case study, bibliographic, documentary. The classification as to the ends consists of research, exploratory, descriptive, explanatory, qualitative, quantitative. The quality tools will be applied in order to regulate the frequencies of non-conformities, mitigating them from highest to lowest, making it possible to anticipate the causes and effects. To develop the solution proposal, the sector was widely observed, where a comparative analysis of the company's quality indicators was carried out with regard to the Machining sector during the 12-month period. the present analysis of causes was built from this tool, identifying non conformities that were found in the analysis of the current situation and I verified how these non-conformities found in the CNC machine and tools directly influenced the occurrence of the work problem. In the project, the fixation of the entire tooling set was taken into consideration to increase the radial rigidity and thus avoid unwanted vibrations. Increase tool life through efficient lubrication. N the cost of unusable parts, the goal of the headstock's production area was to be spent per month: R $ 25,000, were being spent / month before the improvement project, R $ 62,524.00 and after the project was implemented, expenses R $ 29,719.20, a reduction of R $ 35,804.80 in unused parts, in just 1 month, in addition to the other evidenced gains. In short, the application of the theory and concepts of authors in everyday organizational phenomena and the absorption of knowledge not only from theoretical content, but also through field analysis, to the company, the opportunity for improvement through accessible practices and low cost and provides real benefits to the organization.
