Week 8 - Challenge 1 - Draft Analysis on a Fan Cover
The draft analysis is performed to detect if the part that has been drafted can be removed or not.It helps in analysing the continiuity of the componet and drafting angle of multiple surfaces.We need to ensure the appropriate tooling axis is used while manufacturing.Draft analysis enables the manufactures and designers in knowing proper drafting angles are given to the parts or not.If the drafting angles are not given,it creates friction while removing the component and creats unnecessary wastage.
The tooling axis should be selected in sucha away that the axis should have proper clearance from all the faces.Because its important to minimise the frequency of the manufacturing process for the parts of a same component.
The bisecting method is essential incase the drafting angles used are unequal. For components with complex design and unequal drafting angles,bisecting method needs to be used.So,a common point where the two lines with with different angles meet is taken as the referance point of the bisecting line.
