Passrate Improvement Target December 2014 = 50% January 2015 = 60% February 2015 = 70% Action Plan NoNo PlanActionTarget Date PICCurrent Status 1 Offline & Bar Templates Tuning [Implementat ion] SB32a, SB35a, SB53, SB36, SB31 (a) Prepare rack, powerpack, facilities & checksheet Oct 2014 HARIZ / AIDA STC (1)Quick coupler for water already done. (2)Hose reel for hydraulic hose already done. (b) Prepare Bar Template, Stub and CMM Jan 2015 HARIZ/ SAIFUL AMIR (1)Stub (2)Bar Templates (c) Fine tuning and collect data Dec 2014 HARIZ/ SAIFUL AMIR (1)Monitoring Board is now implemented and updates. (d) Standardization / SOP / On-job-training / Manual Dec 2014 HARIZ/ SAIFUL AMIR (1)SOP to do Offline Tuning also done. (2)SOP for powerpack is done. (e) Review result and improvement. Feb 2015 HARIZ/ SYED AMIR -To do a Monitoring Boards for Hourly Monitoring purpose.

For SB31 & SB36, the barrier is Bar Cannot be fix at the Point-Q. After discuss with Haffizi and Erveen STC, need a major grinding and hot rework. a)Offline start from 10.30am ~ 5pm. b)Technician fill-up checksheet. Actual training has been done on 7 th Jan 2015. 5 Module. 1- Tightening and greasing. 2- Warm-up bending machine by using Powerpack. 3- Checking every item (mechanical, electrical & pneumatic). 4- Do Offline Tuning 5- Put a Green Flag. -Daily updates by technician.

ModelProblemCountermeasure & Figure SB53 (HONDA 2CT) (1)Bar slunting & stuck when robot loading bar to pusher. (2) Mostly die’s already wear-off. Slow progress of drawing handover. (1)Design review with Mr Amin. Re-design With STC. -Already release new design. Now on fabrication. (5 Jan’15) PVD (6~9 t Jan’15) ; ETD 12 Jan - Trial done without Eye twisted. (2)Already fully handover of die’s drawing only. - Has tried new die step 1 & 2 Done - Has tried new die step 3 Done - Change new bracket Step#1 due to thread loose. - Try die step#6 Done Have a Coordination Meeting with Azhar on18 Feb. i - Shaft step#1 (clamp) loose due to shaft wear-off. Temporary : Repair and tighten with double lock-nut. Permanent : Do design review with lock-nut. Current Status : Design complete. On detail drawing. ii - Die step#8 wear-off & cannot be replace because solid-block. Temporary : Touch-up & grind die. Permanent : Re-design. Split between die and block. Current status : Design complete. On detail drawing. iii - Re-check all cylinder and hose. Many leaking. To investigate root cause. SB54 (PROTON GSC/ IRIZ) (1)Bar stuck at jig and marking. (2) Die point-Q already wear-off. All drawing still not handover from STC. (1)Use others type of roller. Temporary using Roller SB31 (myvi). Problem solve with 99% passrate but have a marking at eye portion. To coordinate design review meeting with Haffizi on 2 nd Mac’15. (2)Drawing already handover 29h Jan 2015 (but die’s drawing only). IGES (softcopy)still not handover. 3 10.24mm11.21mm Action For Top 2 Model DO Step 8 Bracket step#1 OLD DESIGN NEW DESIGN

% Data Collection DO Before WEP After WEP % % % % % SB32a (Saga BLM)Passrate drop due to (1)Problem : Eye gap due die wear- off. Countermeasure : Temporary : Yokoten PVD at this model and start to monitor die stroke. Cost saving without Coldset after WEP Program RM % SB53 (Honda 2CT)Passrate drop due to (1)Problem : Pin stuck at Insp. Jig at point-7, 8 & 9. Fine tune with Azhar STC. Step#1 loosen & die step# 8 wear-off. Cannot replace new die because die is solid with block. Countermeasure : Temporary : Fine tune (adjust cylinder stroke) & assisted by Azhar STC. Permanent : To review possible design which easy to maintain by Tool & Die.
