Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1
ATTACHMENT FEATURES (RIBS AND SCREW BOSS) DESIGN AND DRAFT ANALYSIS
- Objective: To create the design of the Attachment Features (Ribs and Screw Boss) for plastic components and also do a draft analysis of such components.
- Tooling axis:
- Firstly, we have to create a tooling axis which is essential for designing the component and also for draft analysis.
- To create the tooling axis, I'm choosing bisecting method.
- With the help of bisecting method, I had to create a tooling axis that probably clears all the surface of class A.
- Now, let's check the draft analysis of class A and the component Door Handle (refer to the below-given pic).
- Class A Surface Draft Analysis:
- Here, the surface of class A is not in good condition.
- So, in this situation, we have to contact the class A designer to provide a draft on these surfaces.
- But this we are doing for learning purposes and our aim is to design attachment features (Ribs and Screw Boss).
- So, neglecting this and proceed further by creating class B, C, and close body.
- Design Rules for creating Ribs:
- Design Rules for Creating Screw Boss:
- Rib Root Thickness Analysis:
- Draft Analysis of Ribs and Screw Bosses:
- Result: Its clears well at 0.45 draft angle
