Week 8 - Challenge 1 - Draft Analysis on a Fan Cover
TOOLING AXIS CREATION & DRAFT ANALYSIS
OBJECTIVE: The main aim of this challenge is to create a tooling axis for a Class-A surface through bisection method and to perform draft analysis
PROCEDURE:
1. Check the connectivity of the surface, this can be done by creating boundaries or by simply using the join option such that any openings can be easily visualized.
2. Analyse visually for the best possible tooling axis.
3. A Dummy tooling axis will be directly created using point-direction command.
4. Check the possibilities in all the directions of axis and find what are all the problem creation parts of the component or model.
5. The clearance checking along all the axis direction will be done by creating an intersection along an axis on a plane with the model and constructing two lines contact with the walls, the line bisecting the two lines and passing through the point will be the tooling axis.
Dummy Tooling Axis Creation:
Using the intersection tool the lines will be created along the inclined walls, these lines are used for creation of tooling axis by bisecting method where the two lines and point will be selected as inputs.
Creating a tool along X direction
After the creation of line in outer walls, create a bisect line along X direction using Bisect option in Line tool.
Creating a tool along Y direction
1. The same process in repeated for the creation of tool along Y direction.
2. Create the lines along the inclined walls and get a bisect line along Y direction.
Create a tooling axis using the tool creation of X and Y directions.
PUBLICATIONCreating a tool along X direction
1. Publication is used to make easily accessible of the published components.
2. Publish the Fan cover and Tooling axis seperately.
DRAFT ANALYSIS
1. Draft analysis is done after determining the tooling axis.
2. Draft analysis is used to check the surfaces whether the minimum draft (3 degrees) is maintained or not.
3. Before the analysis is done check the view mode is in "Material", as to get the correct analysis result.
4. Compass is used to define the draft direction.
5. If the minimum draft 3 degree is provided the whole component changes in to green colour.
