Proposta de ações para a eliminação da etapa de rebarbação de engrenagens para veículos durante o processo de usinagem de uma indústria metalúrgica localizada em Igarassu PE

Abstract

This paper presents an action plan with the objective of proposing actions to eliminate rework by material removal in precision gear parts produced in a metallurgical industry located in Igarassu-PE. For the elaboration of the action plan, the methodology of problem analysis and solution (MASP) was used, corresponding to the P (plan) stage of PDCA. The main causes that encouraged this work were the work overload and the risks of accidents that the operators had during their working hours. First, an observation was made, with the objective of improving the activity during the production process in the organization. In the second step, we sought to observe the problem, clearly describing how the problem is impacting the operational area. In the third step, we tried to identify the root cause, with the help of the quality tool, and finally, in the fourth step, we proposed an action plan based on the 5W1H. This research is characterized as a case study of exploratory and descriptive character. This study has a direct impact on productivity and production efficiency, and brings as a result an action plan, which evidenced he need to improve the machining process as well as upgrade the computerized numerical control (CNC) of the machines, it is also necessary to improve the kaizen sector, this sector is responsible for continuous improvements within the organization. Since, with the elimination of the deburring activity, a significant lower time was obtained. The result was very favorable, the operator will no longer perform the deburring activity of all parts, would only perform the activity of checking the parts with this the process will be more optimized, lean, less overloaded operators, low accident rate, coming to the conclusion that these improvements is viable and both sides.
