The CQI-27 Special Process: Casting System Assessment (2nd Edition) is a critical quality standard developed by the Automotive Industry Action Group (AIAG) to create uniform process requirements for foundry suppliers. The "xls upd" refers to the updated Excel-based assessment tool released with the 2nd Edition, which significantly improved user flexibility and technical scope compared to the original version. Key Features of the CQI-27 2nd Edition XLS
The updated assessment tool introduces several functional and structural enhancements designed to align with IATF 16949 standards and reduce casting defects in automotive applications.
Unprotected Spreadsheet Editing: Unlike the 1st Edition, the 2nd Edition's Excel sheets leave unused columns, rows, and sheets unprotected. This allows auditors to perform common Excel editing to better customize the documentation for their specific foundry layout or customer requirements.
Consolidated Requirement Tables: To streamline the audit process, tables with overlapping or similar requirements were merged. This reduces redundancy and ensures that auditors can focus on the core "voice of the customer" requirements.
Expanded Process Coverage: The update includes 10 specific Process Tables (A through J) that cover a wider range of casting methods, including: Sand Casting (Iron/Steel and Aluminum). Centrifugal Castings and Centrifugal Liners. Investment Castings (Iron/Steel). High Pressure Die Cast (Aluminum, Magnesium, and Zinc). cqi27 casting system assessment xls upd
Mandatory Content Emphasis: The updated XLS places greater weight on requirements that are considered mandatory by OEMs. It explicitly highlights that any deviations from these standards must be authorized by the customer's Product Engineering department.
Revised Technical Clarity: The wording for several requirements from the 1st Edition was rewritten to remove ambiguity, particularly regarding failure modes and root causes. Assessment Scope and Audit Areas
