Problem Raised By: Date: 7/9/

1. Problem Statement (Specific) Excessive qck time resultiy in bw output
2. Clarification of problem (by whom, where, when and how) plus costhenefit opportunity
Chrified with operator on 7/9/
!Discussed opportunities to reduce cyck time m'thout sacrificiy product qua&+
Cost to mohh proframme = 1 bur set-up and1 hour test/inspect
Standard cych time reducedfrom 3 to 2 secondc = e@a 152 units per week (a 10% OEE
improvement)
3. Problem cause (brainstorm and fishbone, then list) 8/8
Caused by 1: Sfiallow depth of cut
Caused by 2: JMovement of ta6k in z-plane
Caused by 3: Relative position of tooliy start position and wor@iece
Caused by 4: geed to manuall reset proframme to start cyck due to multipk
proframma in memo ry
4. Clarification of root causes (Do the causes exulain the oroblem?)
Sigh 10 mm cut is practicalrather than 5x 2 mm cuts
If siyle cut impkmented, ta6le higlit can GefilCedvia proframme
Reduction of tooltravelshortens cyck time
Proflamme Ibcation/multipk pragrammes prevent auto reset function 6eiy utilized,
thus manuall resetfor each cyck
5. Countermeasure (actions required to resolve causes (s))
Temporary-
Permanent
JMohh propamme to siyk cuttiy cyck from 5 cuts
Set traverse ta6k at constant hght in projramme
Reprogramme toolstart position close to worbiece
Store siyk progamme in memory and hate at fine 4 to ena6k auto reset
statement to 6e used
6. Confirmation of countermeasure (Have actions cleared problem?)
Countermeasures awaitiy impkmentation
7. Feedback (Who else needs to know?)
Milkr Supervisor, Maintenance Manager, Tt'M Facilitatoc nominate team for PL?M Excelktue
