Week - 4 - 2D meshing for Plastic components

AIM:

• To check the geometrical errors and take the mid surface by the suitable mid surfacing techniques.
• To mesh the same with give element quality criteria for the given plastic bottle cap model.

OBJECTIVES:

• To rectify the given plastic models of geometrical errors.
• Give the geometry checks and the mid surface of all parent geometry.
• To Assign the PID and Thickness for all the mid surfaces.
• Give the good mesh flow of given plastic model.

PROCEDURE:

• To do the geometric checks of the given plastic model.

• To take mid surface for the given parent geometry for all parts inthe model.
• Using the mannual OFFSET option under the FACES to take the midsurface of parent geometry.
• Mid surface are done by mannual OFFSET of all parts seperately one by one.
• Complicated areas like,TEETH,THREAD taken the mid surface using CURVE middle >project>transform Rotate has to be done,as shown in below.

• Using the mannual OFFSET option to take the midsurface of parent geometry of all other parts has to done,as shown in below.

• In this model,having the Triple cons,so that geometrical errors will be having,as shown below.

• After that ,Go to mesh all mid surface parts and give the good mesh flow.
• Meshing all the mid surface parts has to be done,as shown in below.

• Assigned the thickness of all parent geometry of set new PID of given plastic model.

CONCLUSION:

• Here,I can achived the given Target Element Quality criteria and Meshing also done with target element quality criteria for all geometry parts,as shown in below
