Why 9103 Now? Customer Driven – Clear objectives & milestones (Total Involvement) Timing – Fit into our culture of continuous improvement (We were ready)
Key Implementation Steps • Data Collection • (Establish method and location) • Measurement System Analysis • (Create / Achieve / React)
Key Implementation Steps • Key Process Inputs • (Select & determine control method) • Control Plan • (Development / Implement / Refine)
Some Benefits From 9103 • Addressing of irritating issues • Remove the “it’s good enough attitude” • Focus on upstream processes • (Plan for success) • Documentation of expert knowledge • (Best Practices)
Machining Example Issue - In order to produce a blueprint part a smaller size must be targeted and at times operator would have to creep up to the finish cut
Machining Example Performance - Maximum CPK obtained = .9
Machining Example Before After Groove cut after top dia. Groove cut before top dia. Root Cause = Sequence of turning Corrective Action = Turn groove first Result = Sustainable CPK of 2 +
What’s The Real Benefit? Time – Eliminate “creeping up on” re-cuts (Rework / Yield) Flexibility – Operator experience a non-factor (Better operator utilization) Standardization – Lessons learned (Implement standard changes to all programs)
Welding Example Before process control – Upstream processes were manufactured to blueprint requirements After process control – Upstream processes controlled to enhance the welding processes Detailed mapping of process is critical to visually understand key inputs
Plan for Success Issue - At contract award notified that manual weld process had high M.R.B. activity related to material thinning (KPC) Preemptive Root Cause - Grain structure variation of details being welded Corrective Action - Upstream process controlled (Material thickness tolerance tightened to high side) Result – Sustainable C.P.K. of 1.5
Best Practices Learned Before 9103 – Replacing tungsten in torch was based on operator experience • After 9103 – Control plan states • Replace tungsten immediately if: • Oxidation occurs • Wire contacts tungsten • Or any other sign of contamination
Best Practices Learned Before 9103 – Changing inserts was based primarily on operator interpretation of need CNC programs had “check insert” points After 9103 – Control plan dictates tool change points in CNC program During debugging & approval process of programs experienced operators determine tool change points
Summary • Process control perceived as labor intensive • (A large company initiative) • A balanced diet of customer interaction & flexibility • (Appropriate characteristic selection) • Suppliers need to discover the benefits • (Positive payback)
