Introduction
The document discusses the implementation of a Production Guideline (PG) solution by CSP GmbH & Co. KG at Knorr-Bremse to enhance the quality and efficiency of screwdriving processes in the production of braking systems for rail transport.
Specifications and Procedures
The PG solution addresses the high demands on quality by defining precise torques, rotation angles, and tightening parameters. It ensures that components meet target conditions, which is crucial for the safety of braking systems in rail transport. The system uses visualized work instructions to guide workers through assembly processes, ensuring uniform workflows.
Implementation and Adaptation
The project took two years to implement, involving numerous developments and adaptations. The PG system integrates with existing systems from Atlas Copco and Saltus, supporting over 200 different parameters and requiring batch scans of products before use. The user interface was customized to meet specific requirements.
Worker Guidance and Acceptance
Approximately 40 employees use the PG system, which has been well accepted despite initial reservations. The system includes features like nut selectors with visual indicators to ensure correct tool usage. Training for new processes is now more efficient.
Documentation and Quality Assurance
The PG system documents all production data, including torque, angle, time, and worker details, which are sent to the SAP system. Each braking system undergoes functionality testing, and any deviations are corrected immediately. The system is planned to expand to other processes and locations.
Conclusion
Knorr-Bremse's investment in the PG system has improved quality assurance, reducing the risk of costly errors. The company plans to extend the system to other locations and processes, emphasizing the importance of maintaining high-quality standards.
Company Profile
Knorr-Bremse Systems is a leading manufacturer of braking and on-board systems for rail vehicles, with a global presence in 27 countries and over 11,000 employees. In 2011, the company generated sales of EUR 2.19 billion.
Worker guidance PG brings quality to the rails Making mobility safe is a task that Knorr-Bremse devotes itself to every day. The systems produced by the long-established Munich-based company safely brake streetcars, metros, locomotives, multiple units, freight cars and high-speed trains. In terms of production safety and quality, however, the manufacturer has picked up speed: A worker guidance system uses visualized work instructions to support the assembly of different types of braking systems, thus ensuring an optimum, uniform workflow in the work process.
