Week 9 - Challenge 2 - Switch Bezel Design

SWITCH BEZEL CATIVA  PART  WEEK9       

 AIM : 

     CREATE THE SWITCH BEZEL PLASTIC COMPONENT  THROUGH THE  GIVEN  CLASS A  SURFACE.

  OBJETION :

•       CREATING TOOLING AXIS 
•       CREATING B CLASS SURFACE 
•   CREATING C CLASS SURFACE 

 PUBLICATION : A CLASS, B CLASS , C CLASS AND TOOLING AXIS :

• INTRUCTION :
•    SWITCH BEZEL  IN CAR ARE PARTS  WHICH CONTAINS SWITCHES  AND CONTROLS  FOR  DIFFERENT FUCTION LIKE WINDOW OPEN AND CLOSED  .ACRLY LONITRILE  BUTADIENE STYRENE[ABS ] IS USED  IN SWITCH BEZEL . THE STYLISH  APPEARANCE ADDS OF LUXURY CAR USED

          A CLASS SURFACE : 

    

 REF SURFACE  MUTIPLE EXTRACT  FACE POINT AXIS   CREATE 

TOOLING AXIS :

          TOOLING AXIS OR MODELING AXIS  IS THE DIRECTION IN WHICH  THE CORE AND CAVITY OPENS. IT IS  BASICALLY THE DIRECTION THAT THE  MOLD PULLS APART. IT IS  CREATED  USING  BISECTING METHOD. CREATING TOOLING AXIS IS  NECESSARY TO PROVIDE  DRFT ANGLE ANALYSIS .

BISECTING METHOD :   

      TO DECIDE  THE TOOLING AXIS , THE COMPONENT SHOULD  CLEAR  THE TOOLING AXIS  IN THE GIVEN  SPECIFIC DIRECTION . THE FIRST SETP IS TO VISUALLY CHECK THE  COMPONENT  FOR THE BEST TOOLING DIRECTION  ALL THREE X, Y ,AND ,Z  DIRECTIONS .   IN THE  GIVEN  CLASS A  IT IS  FOUND THAT  THE BEST  TOOLING DIRECTION IS  Z, AXIS  AS THE  HOLES  PRESENT  ON  THE SURFACE CANNOT  BE CLEARED  IN EITHER  X  OR DIRECTIONS WITH MINIMUM TOOLING . SO  Z DIRECTION IS  CHOSEN  FOR TOOLING AXIS .

THE MAIN TOOLING AXIS  IS CREATED  USING BISECTING  METHOD AS  SHOWN IN  IMAGES BELOW .

  

 B CLASS SURFACE : 

     EXTRACT BEZEL SURFACE > SURFACE UNTRIM > OFFSET  >2.5MM 

     

NEXT WALLS :

   EXTRACT WALLS > SURFACE UNTRIM > EXTRPOL> OFFSET >2.5MM

         

BASE :

  EXTRACT BASE > SURFACE UNTRIM > EXTRPOL > OFFSET > 2.5MM 

        

 B SURFACE :   

           

  WALLS > BASE > TRIM > B SURFACE 

C CLASS SURFACE : 

  MUTIPLE EXTRACT1 >  MUTIPLE EXTRACT 2> A CLASS SURFACE >  SWEEP >  NOT JIONT SURFACE EDEGES > EXTRPOL EDEGES > TRIM >   CURE SMOOTH > FINAL C CLASS SURFACE 

     

    

   

   A CLASS + B CLASS  C CLASS : 

JIONT>BOUNDRY > TRIM .

     

         

         SURFACE WORK BEACH > MECHANICAL DESGIN >   PART WORK BEACH .

    

 DAFT ANAYLSIS :

 A CLASS SURFACE :      3deg  a class surface not ok walls show deg [-] valuve 2.7deg smouth suface ok part walls .

  CONCLUSION: FINALLY  THE PLASTIC  COMPONENT OF SWICTH BEZEL  AND DRAFT ANALYSIS WAS DONE SUSCESSFULLY .
