Week 8 - Challenge 1 - Base Bracket Design

Input:

      The input was given as Class A surface.

Tooling Axis:

      The tooling axis was created using Bisecting Method. A point and dummy tooling axis was created with respect to the hole in the class A surface. A Plane was created at the point by offsetting the appropriate plane surface. Class A was intersected with respect to the created plane. Using the intersection lines, two bisecting lines were created using the lines intersecting in both XZ & YZ planes respectively. Bisecting lines were drawn in between the lines from both XZ and YZ planes. This line is the Tooling Axis. 

Draft Analysis of Class A:

       Draft analysis is done on the Class A Surface with respect to the Tooling Axis created. 

          The minimum draft angle was given as 3 Degrees. 

Class B Surface:

       Class B was created by simplifying the faces of the Class A Surface by dividing them into multiple small sets. Such created sets are offset to the thickness of the component, (i.e.) 2.5 mm. Finally, these sets are trimmed together to achieve the desired class B Surface. The commands used here are Untrim, Extrapolate, Trim, and Offset. 

Class C Surface:

     The boundary is created from the Class A surface and it is extended along the Z direction using the Sweep command with the created boundary as the Guide Curve and Tooling axis as the reference direction, Sweep is done in the appropriate direction for every boundary. The Class A surface is joined along with the created Sweeps. And thus the Class C Surface is created. 

Closed Surface:

      In the final stage of the surface creation, The Class A Surface and Class B Surface are trimmed to gether to form an appropriate closed surface. 

Part Body - Base Plate:

      The part body is created using the close Surface command in Part Workbench with Closed Surface as the reference surface.

Draft analysis of the Component:

        Draft analysis is done on the Coimponent with respect to the Tooling Axis created. 

       The minimum draft angle was given as 2.8 Degrees. The minimum draft value was reduced to 2.8 degrees from 3 degrees due to technical difficulties and it is done only after confirmation from the technical instructor.
