Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1
AIM: Create the rib for the Drill Handle
- To Create the Door Handle Component from the given Class-A surface.
- To Create the tooling axis for the given Class-A Surface meeting the requirements of the draft angle.
- To Attach B side Features in the component.
- To perform the Draft analysis on the model.
DESCRIPTION:
1. CREATING TOOLING AXIS -
Given Class A

- Check for gaps between surfaces for that click on join and then preview.
- If theres any gap between the surfaces join them with a maximum tolerance of 0.003 mm.
- Extract the boundary and dissemble the boundary.
- Find the correct tooling axis where the material don't interfere with the tooling axis and all the elements can be created.
- Create an axis system using at the centre of the switch Bezel.
Tooling axis represents the opening and closing of the mold core and cavity during the manufacturing of the components. A plastic product designer should consider the best tooling direction to cutdown the cost of the component very less.
Method opted for creating tooling axis for the bumper
- Check the best tooling direction for the given surface.
- We can find out the best tooling direction by cross checking all the three axes

3. DRAFT ANALYSIS
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 color ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.
- Before going to drat analysis go to customized view parameter >under mesh >check material and then click ok.
- Now for draft analyses go to insert » analysis » feature draft analysis.
- Use the compasss to define the draft direction.
- In the colour scale change the draft angle to 3 degree.
- The component changes to green in indication of passing draft angle.
- Use running point to check the angle on the component.

- The draft analysis is complete.
4. CREATING CLASS B SURFACE
- offset 2.5mm from the class A
- Insert them into new geometrical set and name it with respective part names.
- Use multi - section tool to modifiy given class B surface.


5. CREATING CLASS C SURFACE
- Extract the boundary from the class A surface using boundary command.
- Using disassemble tool to divide the boundary as the boundary contains domains.
- Use sweep command > choose profile type line > subtype as with draft direction > choose guide curve and draft direction > draft angle as 3 degree > preview.

- After getting sweep then join the output with class A surface to get final output.

- Now trim with Class a + c with Class B


Create close body in part body

7. END DRAFT ANALYSIS


CONCLUSION:
- The Tooling axis and the Solid part with B Side Features is created from the given Class A Surface and Draft Analysis is Performed.
