Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)
Attachment Feature Creation (Ribs & Screw Boss)
Objective
1 - Learn how Create the Door Handle from the given Class-A surface.
2 - Learn how to create attachment feature (Rib & Screw Boss).
3 - Learn engineering Approach For create Door Handle And its attachment Feature.
Approach For Door Handle Creation
1 - Create Tooling Axis (For checking Mold opening and closing direction)
2 - Draft Analysis With respect to tooling Axis for Analyzing The part is manufacturable or not.
3 - Create B surface by using given Master section (Class A)
4 - Create C surface by using class A And tooling Axis.
5 - Create close surface by using Class A, Class B & class C surface.
6 - Create Solid Door Handle By using Close surface.
7 - Finaly doing draft analysis for checking the solid body manufacturability. And draft angle.
Assumption For Door Handle
A - Thickness – 3mm
B - Draft Angle – 3*
C - Material – Plastic
Steps to Follow
1 - Check the connectivity of the class A, ensuring that no gap between two surfaces.
A - Using Join command
B - Boundary command – to check the boundary of the A surface (there is not any opening consider)
2 - Find the tooling axis of the component
3 - Tooling axis is the direction at which the mold open & core & cavity opens.
4 - Analysis the component & find which is the best tooling direction (X, Y, Z)
5 - Draft analysis (Insert – Analysis – Feature Draft Analysis)
6 - Create B Surface
7 - Create C Surface
8 - Join A Surface with B, & C Surface & create a closed Surface.
9 - Using close surface command Create Solid Part.
A Surface is the surface that is created by the concept sketches made by free hand sketchers. this computerized design is known as Class A surface.
B Surface is created by using class A surface, and the distance between A surface and B surface is equal to the thickness of the part, it is also called engineering surface.
C Surface is created for connect Class A and Class B surface also known as the side wall of the surface.
Tooling axis
1 - Tooling axis is the direction at which the mold open & core & cavity opens.
2 - Analysis the component & find which is the best tooling direction (X, Y, Z)
Draft analysis
Draft analysis is done to see the manufacturability of a part, green color indicates that all parts are clearing when core is removed from cavity.
A - The part has fully constrained like.
B - It does not have any negative draft.
C - How does the part behave.
D - What is going to the constrain whether it is maintain the same radios.
E - You don’t have any undercut in part, you have maintained 3.0 plus thickness radius.
F - You have minimum hold requirement Gap.
