Week 8 - Challenge 1 - Base Bracket Design

Aim: create the base bracket plastic component through the given class A surface.......

Class A surface

Step 1: check the connectivity of class a surface and inside that there is no gap in the component and we can visually check it by clicking boundary command.

Step 2: create the tooling axis of the component

Create the tooling axis along the z direction.

Intersect the YZ plane with the component as a result we get two line on YZ.

So the main tooling axis is along Z axis.

Now perform the draft analysis using the featured draft analysis tool in the tools

then after opening the draft analysis Toolbox go for the compass and place the compass align to the tooling axis and click on the lock symbol after aligning and further click on the surface then it will be shown green coloured.

Now measure individually

How to Creating class B surfaces ?

Step 1: extracting the right side rib using extract option from class a surface

Step 2: perform untrim

Step 3: perform extrapolate to increase the length upto 10 mm.

Put in the surfaces to required surface then offset the surface 2.5mm in order to get the required thickness.

Similarly create the left side rib……(follow the same procedure)

Similarly you can get the base as well as final base surface and offset (2.5mm) it to desired value.

Now fillet the surface to required amount and give some colour to the model.

Creating class C surface….

Bisecting method is basically use to find the proper tooling axis using the dummy tooling axis. In bisecting method bisecting line is used which either bisect the two line or it will show error which means the two lines are parallel to each other in order to know whether the particular surface is tool able or not we intersect the surface with the respective plane and get a sketch with consist of two lines with the help of bisecting line option. We bisect the line which create a line at the mid point of the two line. Like wise we create tooling axis for X and Y which will be used to create the main tooling axis using the bisecting line option in the line command.

We have to sweep option.

Selecting the draft direction in the sweep bar menu.

Get the boundary of the class A Surface with the boundary command.

now click on the sweep command.

Select the boundary of class A surface iin the 1^st option and select the tooling axis as reference.

Now we get the class c surfaces.

Now you can trim the class C surface with class B surface.

Now you can get the solid part by selecting the close surface in the part design.
