Week 8 - Challenge 2 - Base Bracket Design
Challenge :
Creating the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface will be created meeting the requirements of the draft angle and at the end of performing the Draft analysis on the model.
Step : 1
In order to create the tooling axis for the component, we had to create the bisecting lines for the axis according to the shape of component by intersecting lines of it.
Step : 2
Using the insertsecting lines, we are creating planes at the point, creating the bisecting line in the intersecting lines aswe get our tooling axis shown below.
Step : 3
Performing the Draft analysis by using tooling axis we generated with angle of 3 degree and the thickness of 2.5mm. in order to initaite the analysis we have set the compass to the tooling axis and arrest it.
We gonna set the colour code by green in 3 degree is okay, red colour as 0 to 3 degree and orange has - 0 which is not accepted.
Step : 5
Analyzing the draft angle by using checker over the surface of the component. finally our darft angle is displaying green hence it is accepted.
Step : 6
To create the B class surface from the given class A surface, by extracting the surface from the given component.
we going to untrim surface and going extrapolate the extracted surface to get the definite shape before it filleting or trimmed.
Once the surface get meeting each other, now we are gonna trim the surfaces and gonna offet to the 2.5 mm has shown below. following this for other side also to get the aashape of the component.
We going to trimmed out the extra surface to get the proper shape and gonna fillet the edges to make smooth surafce as shown below.
Step : 7
To create the Class C surface, simply gonna sweep the boundary edges of Class A surface to the drafting angle of 3 degree.
Step : 8
Finally we are gonna get the final plastic component to make the solid body by trimming the Class C surface by B surface. to get the final product. and making it into solid body.
