Application of the TPM in the automatic cutting machine CNC ESAB Suprarex to improve the Overall Equipment Efectiveness

Abstract

The main objective of this research was to implement the total productive maintenance to improve the general efficiency of the automatic cutting machine in SIMA Metal Mechanical. The type of research was applied with an experimental design in the pre-experimental classification, it was pointed out that the study had as a population the 4 oxyfuel cutting machines and 2 cutting machines, the sample was the ESAB Suprarex CNC automatic cutting machine. As a result, the main causes of the low general efficiency of the machine were the unscheduled stops and the high cost of corrective maintenance, in addition, the initial OEE was limited, which had a value of 40%. The implementation of the TPM, through 4 of its outstanding pillars, increased availability from 72 to 80%, performance from 57 to 69% and quality from 99 to 100%, and finally an OEE value of 55% was obtained. It was concluded that the implementation of the TPM increases the OEE of the cutting machine, since it increased by 15%.
