Week 8 - Challenge 5 - Door Trim Lower

Q:- A detailed report should be done explaining the draft analysis and the tooling axis creation.

Aim:- To create tooling axis and perform draft analysis.

Introduction:-

1. Tooling axis:- It is axis about which component is being manufacturer. Core moves along with this axis. It gives the direction of ejection of component.
2. Draft analysis:- It ensures sufficient inclination to be provided to surfaces of part. Sufficient draft ensures easy removal of part from core and cavity. This has to be carried out before part is send to CAE.

Procedure:-

1. Tooling axis creation:- Following are the steps involved in tooling axis creation
2. Check for continuity of given class-A
3. Visual check for tooling axis and create dummy tooling axis
4. By observing it is conclude that tooling axis must be created perpendicular to class-A
5. so flat surface of door trim lower is chosen
6. Taking middle point on that surface
7. A line is drawn from that point perpendicular to surface
8. And this line will be our tooling axis

b. Draft analysis:- Following steps has to be follow for draft analysis

1. First of all we need to activate material from customize view parameter section
2. Using draft analysis tool, we need to alined co-ordinate system with tooling axis and lock it
3. Then by clicking on surface of part we can see colour shading
4. Green colour tells us passing of surfaces in draft analysis, that is they have minimum draft angle needed
5. Red colour shows rejected surfaces
6. While blue colour shows passing of minimum draft angle but in reverse tooling axis
7. Provided class-A gives green colour in direction of tooling axis, so it passes the draft analysis
8. As well created solid body also passes draft analysis, hence it has minimum 3 degree of draft on each side
9. But some region of c- surface is clearing with class-a while some region is going to clear in class-b, so it shows some patches in blue
10. As well transition areas from green to blue shoes red in colour.
