Week 8 - Challenge 1 - Draft Analysis on a Fan Cover
1.Title of the Project:
To perform draft analysis on a fan cover using Catia V5.
2.Objective:
To perform draft analysis on a fan cover by creating tooling axis class A surface data using Catia V5.
3.Methodology:
Class A Surface continuity:
It is the initial stage, such that the class A surface input data is verified for its continuity, and ensures that there is no dis continuity in between two surfaces in the model.
Tooling direction:
It is analysing the model visually to check which direction would be most optimum for tooling axis, such that it would result in gaining better product with optimum cost.
Dummy tooling axis:
By selecting the model, the intersection data is gathered along the selected axis and create a dummy tooling axis, which is considered as reference.
Creation of tooling axis:
After creation of dummy axis, by selecting the X and Y axis planes an intersection is generated. Using the bisecting lines the intermediated tooling clearing along their direction is generated. Using this tool clearing direction lines, the actual tooling axis is created for the fan cover model.
Performing draft analysis:
By applying the material to model, draft analysis is done by aligning the compass to the tooling axis and minimum and maximum draft angle is entered to get the desired result on the model.After interpreting, if there are any negative draft angle is identified, then the tooling axis or the model needs to be isolated for further design correction.
4.Tooling axis:
The defintion tab on the tool as dialog controls,desired orientation of tool itself during cutting process.through multi-axis toolpath.total as select to define tool orientation.
5. Draft analysis:
Draft analysis is performed on a component in order to identify whether there is any negative and positive angle is involved in the component.This draft angle allows the part to eject easily from the mold. The draft angle reduces the friction between mold andpart.it also tends to avoid the damage occurring to the mold and part during ejection processes frequently used draft angle is 3 degree and minimum draft angle is 0.5 degree.
6.Publication:
It is a feature used to make an easy access of the sketch or the surface feature. This feature reduces the time of searching for exact feature which is inside the geometrical set or the part body.

8. Conclusion:
Based on the requirement the draft analysis is carried out on the fan cover, by creating the tooling axis using class A surface data. The results ensures that there is no negative draft angle involved in the model. This draft analysis ensures that, the part can be manufactured easily.
