Week 8 - Challenge 3 - Coin Holder Design

COIN HOLDER DESIGN

COIN HOLDER IS THE ONE OF THE PLASTIC COMPONENT IN AUTOMOTIVE CAR. TO CREATE COIN HOLDER DESIGN NEEDED THE CLASS A SURFACE FOR REFERANCE TO DESIGN THE SURFACE MODELING.TO BEGAIN THE TOOLING AXIS FOR GIVEN CLASS A SURFACE. AFTER THAT TO CREATE CLASS B AND CLASS C SURFACE. GIVEN THICKNESS OF COIN HOLDER IS 2.5.

TOOLING AXIS

• TOOLING AXIS IS IMPORTANT TO DESIGN SURFACE MODELING. IT WILL BE RESPECTIVE TO CORE AND CAVITY OF THE MACHINE.
• TO BEFORE CREATE TOOLING AXIS HAVE TO ANALYSIS THE CLASS A WHICH POSSIBLE SIDE TO CORE AND CAVITY TO PLACE.
• TO CREATE TOOLING AXIS INTERSECT THE CLASS A SURFACE IT MAKE HAS A 2D.
• IN INTERSECT OF CLASS A SURFACE DRAW A LINE AT SIDE OF CLASS A SURFACE.
• USE BISECTION LINE COMMEND DRAW A TOOLING AXIS WITH BISECTING THE TWO LINE.

CLASS A SURFACE

• CLASS A SURFACE IS INPUT OF MAKE THE SURFACE MODELING.
• CLASS A SURFACE HAS BEEN CREATE IN ALLIAS TOOL.

(CLASS A SURFACE)

CLASS B SURFACE

• CLASS B SURFACE IS COPY OF CLASS A SURFACE IT BE OFFSET OF 2.5MM.
• TO CREATE CLASS B SURFACE NEED TO EXTRACT FROM CLASS A SURFACE WHICH TO NEED FOR CLASS B.
• IN COIN HOLDER DESIGN IT HAS HOLLOW BLOCK. TO EXTRACT SIDE WALL OF BLOCK AND UNTRIM THE EXTRACT.
• AFTER UNTRIM THE SURFACE AND EXTRAPOLATE THE SURFACE AT THE CERTAIN DISTANCE.
• AS SAME PROCESS DO IT ALL SURFACE.
• AFTER CREATE COPY OF CLASS A SURFACE NEED TO OFFSET THE 2.5MM AT THE CLASS A.

CLASS C SURFACE

• CLASS C SURFACE IS A THICKNESS OF SURFACE MODELING.
• TO CREATE A CLASS C SURFACE EXTRACT THE BOUNDARY OF CLASS A SURFACE.
• AFTER THAT UNTRIM AND EXTRAPOLATE THE SURFACE.
• USE SWEEPT COMMANT FOR THICKNESS OF THE SURFACE.
• IN COIN HOLDER DESIGN IT DOESN'T HAVE DRAFT SURFACE. SO USE WITH REFERANCE SURFACE PROFILE FOR THIS DESIGN.

• AND GIVE A ANGLE OF 90deg TO CREATE A THICKNESS.
• AFTER THAT JOIN THE CLASS A SURFACE AND CLASS C SURFACE.
• THEN TRIM THE JOIN SURFACE AND CLASS B SURFACE.
• THEN IT WILL CREATE SURFACE MODELING
