Week - 5 - 2D meshing for Plastic components

AIM : TO CHECK FOR GEOMETRICAL ERRORS AND MESH THE PLASTIC BOTTEL CAP MODEL BY GIVEN ELEMENT QUALITY CRITERIA

MODEL IMAGE :

PROCEDURE :

1. GEOMETRY CLEANUP

2. GENERATING MID SURFACE

3. ENTERING GIVEN ELEMENT QUALITY CRITERIA

4. MESH GENERATION

5. RESULT

GEOMETRY CLEANUP :

• IN THIS GEOMETRY CLEAN UP PROCESS THE GIVEN CAD MODEL WAS THROUGHLY CHECKED FOR GEOMETRICAL ERRORS SUCH AS DEFORMATION OF FACES, TRIPLE CONS AND UNNECESSARY CUTS THAT INTERRUPTS ORIGINAL FACES.
• THEN THE SHAPE OF PLASTIC MODEL WAS REFINED BY USING SMOOTH TOOL.
• FINALLY WHILE RUNNING GEOMETRY CHECK IN CHECKS TAB IT SHOWS THAT NO ERROR WAS FOUND SO THE GEOMETRY CLEANUP IS SUCCESFULL.

GENERATING MID SURFACE :

• THE MID SURFACE WAS TAKEN ONLY AFTER THE GEOMETRY CLEAN UP WHEN THE CAD MODEL PASSED THE GEOMETRY CHECK COMPLETELY.
• AFTER LOT OF TRIAL AND ERROR THE AUTOMATIC MID SURFACE GENERATION WAS FAILED DUE TO CRITICAL GEOMETRY SURFACES
• THEN MID SURFACE WAS CARRIED OUT USING MANUAL OFFSETTING AND ALSO TRIED WITH CASTING.
• FINALLY MID SURFACE GENERATION FOR PLASTIC BOTTLE CAP IS SUCCESFUL.

ENTERING QUALITY CRITERIA :

MESH GENERATING :

RESULT : SINCE THE FINAL MESH OF PLASTIC BOTTLE CAP MODEL SATISFIES ALL THE GIVEN ELEMENT QUALITY CRITERIA SO THE MESH GENERATION IS SUCESSFUL.
