Riassunto analitico
This thesis undertakes an examination of the roof assembly for the MC20 Cielo model within Maserati Modena's quality department. The primary objective is to address any anomalies through the application of Maserati's issue management methodology.
Specifically, this thesis is divided into two phases. The initial phase is centered on conducting a preliminary investigation into the product, manufacturing processes, and internal methodologies for quality evaluation. The subsequent phase is dedicated to an explication of issues pertaining to the roof assembly and the corresponding solutions implemented.
The first chapter provides a comprehensive overview of the Maserati MC20's product and production processes, thereby affording the reader the opportunity to acquaint themselves with the vehicle and gain insight into its manufacturing process.
Next, analyzing technical solutions of the canopy interfaces of MC20 Cielo that related directly to convertible rooftop positioning. The analysis of the main components through their respective technical drawings is first presented. Special attention is given to their assembly and functionality. Following this, the mounting process of the entire door assembly is explained. This study is of utmost importance, not only for understanding the complexity of the convertible rooftop, but primarily for establishing a solid foundation for troubleshooting.
Subsequently, a brief benchmarking analysis was performed to investigate the convertible rooftop solutions utilized in the market. The objective of this analysis is to gain insights into the MC20's competitive positioning, examining the solutions it has adopted from both technical and aesthetic standpoints in comparison to its rivals.
In the fourth chapter, Key Performance Indicators, Maserati's Issue Management approach, and Process Capability Indexes are introduced. Key Performance Indicators enable the assessment of both product and process quality, whereas Process Capability Indexes provide a means to monitor the process against engineering limits. Simultaneously, the resolution process is outlined as the systematic flow to be employed for anomaly analysis.
In the fifth chapter, we address and resolve the following anomalies: noise during driving, water infiltration in the B-pillar area, and aesthetic issues. The analysis of these problems initially involved identifying three distinct root causes. Subsequently, we resolved these issues by recalibrating the equipment used for assembling the convertible rooftop in the car, redesigning the tools, and introducing a new jig for the striker of the windshield frame. The effectiveness of these improvements, which is summarized in the final chapter and tested across a diverse range of cars, has ultimately enhanced the overall product quality.
