Air Disc Brakes Couplers (Automatic Railway coupler) (AAR) LHB
Air Disc BrakesThis is connected to the wheel and/or the axle. To retard the wheel, friction material in the form of brake pads, mounted on the brake calliper, is forced mechanically, hydraulically, pneumatically, or electromagnetically against both sides of the disc. Friction causes the disc and attached wheel to slow or stop.
CouplersA coupling (or a coupler) is a mechanism for connecting rolling stock in a train. The design of the coupler is standard, and is almost as important as the track gauge, since flexibility and convenience are maximised if all rolling stock can be coupled together. 8 sets a day (load dependent )
LHB brakes Linke Hofmann Busch (LHB) LHB care passanger compartments of train developed by
Linke Hoffmann Busch of Germany and produced by Indian rail coach factory Karurthala.
The coaches are designed for operating speed upto 160km and could go up to 200km/h.
Their length is 23.54 M of A/C and width is 3.24 M. The coaches are made up of stainless steel and interior
are of aluminum.

Conclusion of above data
After studying the GRN trend it is observed that for Baddi plant most of the parts come from Delhi NCR region and Chandigarh region only two suppliers are in Nalagarh and one supplier is in Ludhiana.
We suggest to keep one SQ team in Delhi NCR region and one in Chandigarh region. The goods that are coming from supplier end will be checked and given green signal over there itself. This will decrease the transportation cost of sending team for regular audit

DATA ANALYSIS CONCLUSION
Pareto analysis has been applied after studying the given data and following conclusion was deduced:
The maximum defect obtained is machining defect in both fiscal year 2014-15 and 2015-16.
From data analysis we can conclude maximum defect is from 3 suppliers namely : YAMADA,KRISHNA,METLONICS.
Problems identified (data)
Old drawing used Purchase order communication gap Packaging standards not followed Inspection process standardization Inspection tool standardization Operation time (supplier capacity, infrastructure, validation) Tool wear Operator carelessness Operation missing
Number of problems (2015-16)
Suggested solution
Old Drawing Used
Suggested Solution1. Highlight the drawing changes(or use different colour background) .2. Penalize the supplier .
OLD DRAWING USED
SUPPLIER END
PURCHASE
AuditingCommunication Gap
Poor info flow to operators
Supplier Negligence
Packaging Standardization
Packaging standards for each supplier must be defined. Agreement of packaging. Colour code cartoons for each product and company. The box should be reused(supplier)
Operation Colour Scheme
Inspection Standardization The process of inspection must be given by
Faiveley Transortation. Inspection technique should be same of supplier
and Faiveley. ODC (Operator double check ) should be applied.
Operator Double Check In this method , each operator will check the operation of previous two operators

Inspection Tool Standardisation
The tool used for inspection at supplier end and at Faiveley must be same and of same least count.
The method of using the tool must be standardised. The calibration period must be defined. Reference point must be pre defined for supplier and Faiveley.

Operator Negligence
Standard process
Standard gauges not used
Tool not well calibrated
Tool Wear Policy
The tool must be changed after pre defined time. Regular inspection of tool. Cutting fluid (if possible) must be used.

Operation Time
By carefully studying the Job Flow process and calculating different allowances, the number of parts to be produced in a given shift must be defined.
The allowance given to the operator must be confirmed from supplier end.

Incentive based approach
Operator carelessnessAn Operator can be rewarded if no defects is found in his operation for continuous 3 months. This will help in creating work attitude.
Expected Effect
Conclusion
By implanting the above suggested technique we will be able to reduce 28.70% i.e. more than 1/4th of the inspection.
Long Term Approach Moving multiple vendors to lean vendor model. Establishing Supplier Quality(SQ) in Chandigarh and NCR region. Investment on vendors. Complete automisation of machining at supplier end. The supplier should have capability to develop and validate the product
process. Inspection should be made atomised. inspection at supplier end not effective
Respective SQA team to train inspectors at supplier end process capability for critical parameters of runner parts are not established
so define process capability check point at PDI stage Keep two suppliers for parts - primary and secondary. If order amount
increases then give the parts to secondary supplier to manufacture which will help to bring down the workload on primary supplier
Working Attitude
We must help the supplier in setting the Vision and Mission of the supplier so that he can always work progressively
We should help the workers in knowing the value of their work and creating the work attitude
Quality circle
We should create quality circle both at supplier end and at Faiveleywith the aim of CONTINUOUS IMPROVEMENT
