Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

AIM : Create the rib and screw boss for the Drill Handle considering the design rules .

Tree Structure

Draft Angle:

• Draft angle is the degree of taper that is incorporated into the side wall and part, core, and cavity of the die-cast tool to aid in the removal of a part. Primarily, their function is to reduce the friction between the part and the tool as it is ejected. Without draft angles, parts can be stripped, dented, or get stuck in the tool.
• Draft angle also reduces the friction between the part, core, and cavity and also reduces the production time as it is easy to reject the part from the core and cavity.

Draft Analysis:

• As the name suggests, draft analysis is nothing but checking the draft angle range i.e., whether the angle is in the ideal range of 3 degrees or not.
• In this analysis we have a colour scale where we can see the range of a specific colour and we can even change the range by double-clicking on the number.
• To do draft analysis go to insert-Analysis-Featured Draft analysis.

Steps to create a tooling axis :

Tooling axis creation-

The steps to follow for creating a tooling axis:

Open the file which contains the Class A surface,after creating a geometrical set "Tooling Axis" then select the most appropriate position which can clear the part in one short for manufacturing.For the given class a surface I have created tooling axis by using point with direction in line command.

For this first i have created a point on the class A surface using point command.

Then using line command with point direction drawn line .

Conclusion:

• Hence all the submission requirements are successfully done and the CATPart file is attached below using the Browse option.
• Given Class A, Draft analysis is not clearing with the angle of 2.9 degree and C surface also not clearing draft analysis in edges of the class A and below the class A surface.
