Optimization of the CNC machining process of the Ball Housing area, through a maintenance program

Abstract

Optimization is one of the most widely applied techniques in the industrial sector, offering the possibility of efficient resource utilization. Based on this, INNERMAX, a machining company, carries out a preventive maintenance program for CNC machines in the Ball Housing line. This is due to frequent stoppages caused by faults, resulting in low productivity and financial losses, leading to customer dissatisfaction due to the low quality of the final product. To implement the preventive maintenance program, detailed information about machine faults and production over five months is collected. This information is analyzed using quality tools such as Ishikawa diagram and Pareto chart. Additionally, the availability of each machine is evaluated, and Overall Equipment Effectiveness (OEE) is calculated to understand the current state of the company. As part of this program, a quality control plan is developed to manage and ensure product quality. This involves standardizing the process and improving the workflow from raw material reception to the shipment of the final product. Furthermore, a procedures manual for non-conforming products is created, allowing better control and understanding of the actions to be taken when detecting any discrepancies. Thanks to these measures, INNERMAX optimizes its processes, enhances product quality, and ensures customer satisfaction.
