Week 9 - Project - A pillar Design with Master Section

AIM

To make a full solid model from the provided master section and class A surface.

METHODOLOGY:

CLASS A SURFACE:

It is surface which is made by the designer. They have given master section which is used as reference and form B surface and engineering surface.

TOOLING AXIS CREATION:

• First create the class A surface and manually analysis and fix the direction of tooling.
• In this part two hole on the surface. So, we can directly take its perpendicular as the tooling axis because its most suitable for tooling axis.
• First created the point on the surface and create new axis system.

• DRAFTING ANALYSIS:

• 
• Compass is fixed on the tooling axis.
• Then we click on the surface it showing different colour. This colour is used to analysis the drafting value of surface with the help of analysis table.
• It is zero-degree draft component. So, we no need to take drafting analysis. If we take it will show zero-degree draft angle.

CLASS B SURFACE:

It is bottom side surface of class A surface. It is formed with thickness distance from class A surface.

1. We directly offset the given surface at 2.5mm distance inside with the help of offset comment fore b surface
2. Some discontinuous surface filled with some comment like blend, fill, Mss etc.
3. If we need any bounty expand with the help of extrapolated comment.
4. Trim unwanted surface
5. Finally, we got surface B class.

CLASS C SURFACE:

It joins the both class A and class B surfaces. This surface is equal to the thickness of the component

1. Extract tool is used to create the boundary lines separately on side edges of class A surface

Sweep comment is used to create surface C class for separate edges from given master section reference. Finally merge all sweep surface to get class C surface.

A B C SURFACE

DOH HOUSE AND RIBS

• Join command is used to join the surface A class and the surface A, C class
• Trim commend is used to trim class AC and B. They join themselves.
• Finally, we got hollow product.
• In this part there is hole like on the top of the dog house.
• First, created middle part is joined with dog house.
• The draw hole on the top wall and extrude the this extrude surface is used to split from the dog house. We finally got full engineering feature.
• The this dog house model is joined with the created pillar body by union trim operation.
• Finally, we have got full model with master section reference. Next we will do draft analysis.

DRAFT ANALYSIS OF DOG HOUSE

I Same drafting analysis procedure is used to analysis the drafting angle. It is used to determine the drafting angle of part in difrent postion by main tooling axis and side core tooling axis.

CONCLUSION:

Different commends are used to create the surface A class, B class, C class. Then join and convert the solid. Finally, B surface and solid part of surface are created from provided class A surface. Dog house with ribs are created by standard guide lines. Full model is successfully created by master section and draft is analysed by CATIA software.
