IMPLEMENTATION OF OEE INDICATOR IN DENTAL IMPLANTS MACHINING MACHINE

Abstract

Introduced by Seiichi Nakajima, one of the creators of Total Productive Maintenance (TPM), the indicator OEE – Overall Equipment Effectiveness – is used as a metric for operational performance, being a productive management tool increasingly used in the industry. Study, lacks an effective indicator to indicate the efficiency of its equipment. Thus, this work applied the Overall Equipment Effectiveness (OEE) indicator in order to identify the overall efficiency of the most critical equipment in the manufacturing process of dental implants in a machining company located in Joinville-SC. access to machine data in the company which served as the study environment, collect the main equipment data, perform the calculation of the OEE indicator with the information obtained and direct the improvement teams with the results of indicators obtained. Therefore, the objective of the referred work is to implement the OEE indicator in a dental implant machining machine. Among the performance, quality and availability indicators, only the performance indicator was above the recommended global average, which is 95%. For the other two factors, incremental measures had to be studied and recommended to the improvement teams, since the value obtained for quality was 98% and for availability was 85%, against the recommended 99% and 95% respectively. The work shows that the adapted methodology was efficient to identify the losses of the process, to measure the real use of the equipment and to apply improvement actions in the two indicators that presented values ​​below the globally recommended.
