  5. D M A I C Proceso yb: costo… yp: paquetes con defectos

  6. D M A I C y’s y validación del SM YC1= ------------- (MXN) YB1 =----------- (PPM) YB2 = ----------- (USD) YP1= ---------------- (m) YP2= ----------------- (PPM) YP3= ---------------- (PPM) YB1: ------ (MXN) YP1= Push out force (Nw) YP3= Deformed bushing (PPM) YP2= Burrs presence (PPM) Calibration certificate (Destructive Test) Attribute MSA accepted Dimensional Report for Gage GO / No GO

  7. D M A I C Análisis de capacidad yp1: ------------------ Nivel Sigma:-0.51 DPMO = 696279 PPM

  8. D M A I C Análisis de capacidad

  9. D M A I C Identificación de causas (X’s) YP1= Push out force (Nw) YP2= Presence of burrs YP3= Deformed bushing Causaspotenciales: X1 – Non defined welding parameters X2 – Reworked electrodes X3 – Different Method between Shifts X4 – Electrode not parallel X5 – Electrode not perpendicular X6 – Misaligned electrodes X7 – Method to place piece in welder

  10. D M A I C Validación de causas X6 Misaligned electrodes (concentricity) YP3 6 measurements around electrodes pulled together 1 sample-t Ho: the angle at which electrodes are pulled together is 90° Ha: the angle is different to 90° Null hypothesis is not rejected Electrodes are notmisaligned

  11. D M A I C Matriz de causas verificadas X1  DOE X2 & X7 verified significant X3, X4, X5, & X6 verified not significant

  12. LEGEND Very effective, easy to implement, low cost Moderately effective, Moderately easy to implement, Moderate cost Not very effective, Hard to implement, High cost D M A I C Matriz de mejoras Conteractions: X1 – Establish optimal parameters through DOE X2 – Define the useful life of electrodes

  13. D M A I C Soluciones Análisis por ANOVA, DOE Factorial, Superficie de Respuesta, CDC, etc…

  14. D M A I C Controles “Welding Parameters Register” form updated. Parameters are audited every 14 days. “Set up sheet” now includes the parameters at which the machine should be working.

  15. D M A I C Medición posterior a las mejoras

  16. D M A I C Nuevos niveles Sigma
