5. Problem Analysis
Type | Possible Cause | Fact Verification | Jud |
---|---|---|---|
Man | Semi-skilled manpower, inadequate knowledge of process/operations | Semi-skilled operator was working on machine for parting & drilling operation. | O |
Tool | worn out | Tool life monitoring exist | O |
Material | Bend bar in the raw material | bar observed bend at machining stage. | X |
Method | 100%Checking by relation type gauge, Dial type gauge required for sampling inspection. | Dial type gauge not evident for sampling basis inspection. | X |
Machine | inaccurate machine/variations in machine | All the machine are ok and preventive maintenance being done as per defined frequency. | O |
6. Inspection Method Analysis (Current)
Inspection Method | Other |
Other Inspection Method | Dial type gauge . |
Check Point at Final Inspection | Yes |
Checking Freq. | 100% |
Sampling | No |
Sample Size | 1:1 |
7. Root Cause Analysis (Occurance)
Why 1 | DIM 7.0+/-0.1 under size |
Why 2 | Bar bend (Raw material Ø18.05) & uneven movement while machining. |
Why 3 | Excess bar length 5-6 meter |
Why 4 | Length requirement not given to RM supplier |
Why 5 | |
Root Cause (Occurance) | Excess length of bar Ø18.05mm (5-6 meter) |
Root Cause Analysis (Outflow)
Why 1 | DIM 7.0+/-0.1 under size |
Why 2 | Inspection by Spl. concentricity checking gauge |
Why 3 | Attribute type gauge |
