Week 9 - Project - A pillar Design with Master Section

AIM:

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

CLASS A SURFACE:

This is surface which is made by the Styling designer. It is aesthetic surface and usable outside features are on this surface.

CLASS B SURFACE:

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

CLASS C SURFACE:

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

TOOLING AXIS:

• Class A surface or part is used to manually analysis which is best for tooling and create the axis perpendicular to the product by which it will be easy to eject out from the mould. It is called tooling axis. Mould is open and closed by this axis.

DOG HOUSE:

This is used mainly for three functions.

• To eliminate the sink marks
• To give outside Screw bosses from B surface
• To lift the Screw bosses for height

MASTER SECTION

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. Carefully watch and take this axis with the help of all types of views.
• First created the point on the surface and create new axis system.
• Then this intersect line is used to create the new lines on both wall lines. Then the both lines are used to create a bisecting line in tooling direction or it is zero degree drafting part, so we directly draw line through the line to form tooling axis.
• Change some appearance to this line like thickness, colour, dot lines. Finally, it is called tooling axis. It is published for frequent uses.
• Dog house is created by side core. So, we created separate tooling axis for dog house. Same method is used to create a tooling axis parapedicular to the main axis.

DRAFT ANALYSIS

SURFACE B CLASS CREATION:

1. We directly offset the given Class A surface at 2.5 mm distance inside with the help of offset command for B surface.
2. Some discontinuous surface filled with some commands swept, Mss etc.
3. If we need any bounty expand with the help of extrapolated comment.
4. Split & Trim unwanted surface
5. Finally, we got class B surface

SURFACE C CLASS CREATION:

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

1. Join & Trim command is used to join the surface A class with the surface C class

1. Finally, we got hollow product.
2. In part bench closed surface command is used to get the solid model.
