Abstract - Today in these rapid growing world, the Industrial sector is developing vastly. Various issues may Sand inclusion in various part. occur due to many valid reasons. But in case if due to improper Machining surface uneven. handling and no tag on the defective material; then there are All those mentioned issues further affects the more chances of affecting the quality and customer quality and may lead to increase the B.I.S issue, dissatisfaction. also sometimes if these defective head and block are further moved ahead to customer i.e. Non Confirming Material is a term which means segregation here in this case the customer of production is of defective materials according to various issues. A proper assembly area; if these defective material is decision making is done and then the material’s disposition is done. Decision is taken on daily basis and a DFR i.e Defect moved to assembly then there are lots of Feedback Report is completed daily to keep the record in the chances of breakdown, failure, customer system. dissatisfaction also it can tend to affect the reputation of company which is a severe In our project we are going to implement various techniques problems. like 5s, Kaizen, JIT etc for proper segregation and disposition. We are going to design a layout for defective materials. This implementation of NCM will help the production line to disposed the material properly. Key Words: NCM (NON CONFORMING MATERIAL), Kaizen, JIT (Just In Time), 5s, DFR (Defective Feedback Report), BIS (before In Service).
1.INTRODUCTION:
During adherence of production line of cylinder head and cylinder block we came to know about various quality issues, which are as follows: Supplier issues. Blow hole in various parts. Rust issues. Excess/Less materials. Crack, Scratch on material. Notch missing on connecting rod. Bar code issue. Component number missing or wrong. Ergonomic issues. Thread missing. © 2017, IRJET

1.1 Objective : The main aim of our project is disposition of defective materials properly and segregate them according to their issues. This will reduce the quality problems and also the customer dissatisfaction. We have introduced the NCM to overcome on the issues. 1.2 Non Confirming Materials: The basic definition of NCM is that, “any part or product which has been identified as not confirming to any product or process specification. This will be identified through pre determined location, tags, stickers or bin as required.” In quality management, nonconformity is a deviation from a specification, a standard, or an expectation. Nonconformities are classified as critical, major, or minor. In software engineering, ISO/IEC 9126 distinguishes between a defect and a nonconformity; a defect is the non fulfillment ISO 9001:2008 Certified Journal
