- This page discusses the qualification process for manufacturers in complex production, particularly hybrid additive manufacturing that integrates 3D printing and compression molding. It emphasizes the importance of evaluating machinery, processes, personnel, and testing methods prior to large-scale production to ensure compliance with engineering standards and reliable performance. The qualification process assesses both overall factory capabilities and specific part readiness.
- 6.1: Qualification
- This page covers the crucial qualification processes in manufacturing, particularly for additive manufacturing (AM) machinery and parts. It details the steps involved in Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ), emphasizing tests for machine performance, material consistency, and adherence to specifications.
- 6.2: Production Acceptance Testing
- This page discusses learning objectives for hardware-accepted testing, highlighting lot and part acceptance tests and their relationship with statistical process control (SPC). Lot acceptance testing evaluates groups of parts for compliance, while part acceptance testing examines individual parts. Both tests ensure production quality, with failures resulting in rejections or additional testing.
- 6.3: Fixed Designs and Processes, Change Management, and the Future of Certification and Qualification
- This page outlines learning objectives centered on fixed processes and disciplined change management in additive manufacturing (AM). It highlights the importance of maintaining valid qualifications and certifications through a fixed design process and rigorous change management protocols.
- 6.4: Summary
- This page discusses the importance of qualification in additive manufacturing (AM) for ensuring production readiness through verification of machinery, personnel, and materials. It covers various qualification levels, including organization, machine, part, process, and personnel qualifications. Future advancements aim to automate processes, improve controls, and reduce destructive testing, enhancing flexibility, streamlining certification, and ensuring safety and reliability in production.
- 6.5: Review Questions
- This page explores qualification processes in a wire/plasma Directed Energy Deposition (DED) facility, addressing quality management, qualification steps, operational qualifications, and part qualification methods. It also clarifies misconceptions about feedstock qualification and presents examples of lot acceptance testing, aiming to delineate expectations within qualification frameworks.
- 6.6: Key Terms
- This page discusses qualification and testing processes in manufacturing, detailing Factory Acceptance Testing, Operational Qualification, Production Acceptance Testing, and Statistical Process Control. Additionally, it highlights the significance of Change Management for Fixed Designs and Processes to enhance future certification and qualification methods.
