Week 8 - Challenge 2 - Base Bracket Design

Base Bracket Design

Objective:

To create tooling axis, class B, class C Surface and make it a solid model. Draft analysis of class A surface and the final plastic component.

Introduction:

The Draft Analysis command enables you to detect if the part you drafted will be easily removed.

This type of analysis is performed based on colour ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values

The maximal draft analysis accuracy is 0.01 deg. According to the graphic card performance, this accuracy can be debated.

The different mapping analyses of the same surfaces cannot be displayed simultaneously, even if you have set the mapping analysis in no show. You need to visualize them one after the other.

Class A Surface is a given component.

Creating of Tooling Axis:

Create an Intersection line of class A surface with the help of ZX Plane and take a point and offset plane with the help of point. make surface intersection on with the offset plane. and draw two parallel lines then create a bisection line as a Tooling Axis.

Now,

Creating Of Class B

We have extracted the surface from class A and untrimmed it to obtain the original surface.

Then extrapolate and trim surface and offset 2.5mm to the required thickness and make it rib then follow same on middle surface and external surface.

After Offsetting and trimming all required surfaces and applying fillets to the sharp edges.

Creating Class C Surface:

Creating class C surface is from the class A Surface boundary. Using the boundary command and swept with the help of the tooling axis you can create the class C surface.

Class C Surface

After Trimmed Class A and Class C

Now,

Class A, Class C, and Class B Trimmed Surface:

Draft Analysis for Surface A:

The analysis is done for 3deg. Draft so as we can see all the surfaces are in positive draft.

Draft Analysis of the Final Component:

The main Tooling axis refers to the draft analysis.
