Week 8 - Challenge 4 - Bumper

BUMPER.

TOOLING AXIS.

Sides of the part that appear parallel with the direction of draw (The axis of the cored position (hole) or insert is parallel to the up and down movement of the mold as it opens and closes) are typically angled slightly with (draft) to ease release of the part from the mold. Insufficient draft can cause deformation or damage.

TO CREATE TOOLING AXIS.

First we need to check the component that is create based on normal axis (compass) it realated or not.

For this we need to create a line for line we need a point

place the point where surface is flat to check the draft analysis and create the line It should perpendicular to the component

Then check the normal axis and also the draft analysis passes or not.

If it is passing we can go with normal axis which in softwate by default

if it is not we need to go with making the line (tooling axis) with poin to normal to the surface that surface should be flat.

And then do the draft analysis with the refrence of tooling axis what we made.

FOR THIS EXERCISE.

In this particular exercise class A surface is given as input

Class B and Class C surface should we have to do it properly with the correct draft angle (For this exercise c surface should be flat because the undercut draft are flat so we need to maintain the thickness with 90 deg draft from the Class A surface to the Class B surface).

And make the component as solid body.

And do the draft analysis of that component that we have made.

PROCEDURE FOR CREATING PLASTIC COMPONENT.

Input Class A surface ( it should be in single surface)

Use the join tool to join the surface

Check the boundary with the help of boundary tool.

Draft analysis

And to start creating b surface by manual extract and offset or straight offset .

Untrim the surface and trim with each other and create the Class B Surface

Then stat to create c surface which is in between the in Class A and Class B surface

C surface should have the draft angle too

And trim both the surface with Class C surface.

And to check the surface boundary and draft analysis too.

If any thing goes beyond that we need to inform the styling team to improve the surface model.

Then we need to go for solid model that is close body.
