Os objetivos são analisar o processo interno de classificação e as medições da qualidade como ocorrem na empresa. Justifica-se este escrito pela relevância econômica e social da empresa, no seu ramo de atuação desde 1915, sendo esta empresa fortemente influenciadora do Produto Interno Bruto do município de Nova Esperança do Sul, no Vale do Jaguari - RS, além dos produtos da empresa serem exportados para os cinco continentes do mundo. O problema de pesquisa visa verificar como se procede na classificação da matéria-prima couro e como são os controles de qualidade da empresa? A metodologia adotada apresenta características quali-quantitativa, de abordagem exploratória descritiva. Sendo um levantamento bibliográfico com pesquisa documental e na forma de estudo de caso. Formulou-se um questionário estruturado com respostas nas escalas de sensibilidade e aplicados na população de vinte colaboradores ligados diretamente ao processo operacional. Conclui-se que a empresa trabalha satisfatóriamente em relação à classificação e qualidade da matéria-prima couro. Como aperfeiçoamento sugere-se melhorias na forma parcial de plano de ação, entre elas, sugere-se o uso da ferramenta FMECA (Failure Mode, Effect and Criticality Analysis), os conceitos de classificação de Perfetti (2004) e monitoramento das imperfeições no couro de Georgieva <em style="mso-bidi-font-style: normal;">et. al.</em>(2004), reduzindo às perdas na matéria-prima.</span></p><span style="font-family: Times New Roman; font-size: small;"> </span>

Fault Record

CNC grinder is considered as the key equipment of camshaft production line. Its reliability directly influences the quality of the products. This article takes an analysis of fault record of 15 sets of CNC grinders of production line, gets failure positions analysis, and then reaches data of failure modes, fault reason of CNC grinder. Comprehensive analyses of criticality for the machine are done through establishing models. Therefore, this analysis provides technical basis for repair, maintenance and update of CNC grinder of camshaft production line.

Criticality Analysis

Fault finding and failure predicting techniques in manufacturing and production systems often involve forecasting failures, their effects, and occurrences. The majority of these techniques predict failures that may appear during the regular system production time. However, they do not estimate the failure modes and they require extensive source code instrumentation. In this study, we suggest an approach for predicting failure occurrences and modes during system production time intervals at the University of Hail (UoH). The aim of this project is to implement failure mode effect and criticality analysis (FMECA) on computer integrated manufacturing (CIM) conveyors to determine the effect of various failures on the CIM conveyor belt by ranking and prioritizing each failure according to its risk priority number (RPN). We incorporated the results of FMECA in the development of formal specifications of fail-safe CIM conveyor belt systems. The results show that the highest RPN values are for motor over current failure (450), conveyor chase of vibration (400), belt run off at the head pulley (200), accumulated dirt (180), and Bowed belt (150). The study concludes that performing FMECA is highly effective in improving CIM conveyor belt reliability and safety in the mechanical engineering workshop at UoH.
