This Case Study aims to improve the availability of a critical CNC drilling machine by implementing Lean tools. An analysis of the original scenario is performed by filming the entire process to identify what the main problems are. Afterwards the Overall Equipment Effectiveness (OEE) are calculated. In response to the identified problems, an action plan is developed and implemented to find the root cause of the high number of delays in drilling the components, implementing some Lean tools, namely: 5S, visual management, maintenance and enhancing training to increase the operators’ skills. The implementation of the SMED methodology allowed the reduction of 35.23% of drilling time in part A, with the drilling time going from 105 min to 68 min. In part B there was a reduction of 39.91% in drilling time, with a gain of about 44 min. So, the availability of the drilling machine was improved to 90%, contributing to the increase of the global efficiency of the process, with an OEE of about 85%. The results were positive after the implementation of SMED. Consequently, the availability of the CNC drilling machine has increased, which has increased overall process effectiveness.
