Week 9 - Project - A pillar Design with Master Section

PROJECT

A PILLAR MASTER SECTION

Aim:

To create a A_Pillar_Mastersection through a given input Class A Surface and Tooling axis to Draft Analysis on the A surface and final plastic component.

REPORT:

Door Trim Dog House:

Class A Surface:

• To start the design process we need to find out the tooling axis for the surface and check the drafts using the Draft Analysis tool in CATIA.
• And Publicize the A surface.

Tooling Axis:

• Create an Extract on a flat surface and point on surface 0mm and Create a Line - Point to Direction click on the point and take a Y Axis , give some color and make it a dashed line.
• Take a draft analysis with A surface in positive green and blue, little deviation is there.
• And same thing to do in final draft analysis with final solid component, it seems a deviation green and blue that’s fine acceptable.
• And Publicate the Tooling Axis.

Class B Surface:

• Take a 2.5mm Offset from Class A Surface Downward the unfinished surface we get .
• Take a boundary to make a Sweep, Join and Extrapolate to make a Class B Surface.
• Then Publicize the B-Surface.

Class C Surface:

• Unhide the A Surface to Take a boundary as a reference to make C surface.
• Go to sweep line-> with Reference surface 87 degree draft angle for all sweep.
• And join all the sweep parts to make a Class C surface.
• Then Publicize it.

Class C & Class A Surfaces:

• Join the both and extrapolate to joined Class C and Class A surfaces.
• Then Publicize it.

Final trim:

• Take a Joined part C Surface And A Surface to Trim with Class B Surface, we get the output closed surface body.
• Then Analyze the Draft with the final part.
• Publicize it.

• Then publicize it.

Part Body:

• Take a Final Trim Of closed surface body, go to the part workbench and give closed body to make a solid part.
• Create a Dog House with reference master sections to make after union trim with part body.

Dog House:

• Dog house is an engineering feature used in plastic trim design. Dog houses are used as supporting features. Sometimes other engineering features like snaps; locators etc. are mounted on them to increase their strength.
• Create a dog house with the help of master sections, create a point between make a midpoint and make an axis system on point and another tooling axis also created.
• The rule shown below is that I was making a dog house with this picture.

Conclusion:

The report of “A_Pillar_Mastersections” Has been successfully Done By Myself and thank you!.
