5000T Rework
5000 TPL , Rework (September-2023)
Rework Problem Corrective action
Dent
(3.91 %)
Maximum Dent in K15C because of web
cut mark , punch mark.
Surface
Crack (2.09
%)
Die Crack mark on the non machining area of
crankshaft.
(Crack Die used for CA and tnga2.0 for forging)
and die serration mark in K15C.
Die crack mark impression on non-
machining of crankshaft which we used
to grind and polish the surface. (CA and
tnga2.0 Crack die Used)
Scale Pitting
(1.56 %)
Scale pitting issue increase in all parts. Major
rework in K15C, CA and in TNGA.
To control scale pitting , following action
has been taken in padding die air spray.
1. Extra air pressure at robot 3 finger.
2. Implementation of pressure gauge at
air and water inlet to record the
pressure flow.
Chips
(1.27 %)
In total chips rework maximum observed in
K15C at web 7, 8 & FOD because use of
welded ejector pin.- not followed the W.I.
- Ejector Pin Hardness Low- Under Follow
- Ejector Spare Stock to be maintain- Done
- Ejector pin Welded Never used in
Production. - Under Monitoring.
- Ejector Pin Height to be maintain as per
drawing Standard Length- Done
Others
(0.32 %)
In others rework category, rework because of
Arm oversize, Extra material, cut mark and
Fold.
Maximum rework in K15C and CA because of
Arm 1 oversize in K15C and web cut mark in
