Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)
AIM: Design of ribs and Screw boss for Drill Handle following the design rules.
Procedure
- Creating a tooling axis from the given class A surface using bisection method and analysing the given class a surface.
- Creating class B and C surfaces from the class A surface and tooling axis with a draft angle of 3 degrees using sweep.
- Joining the class A and C surfaces and timmed with the B surface to form the closed surface .
- From the closed surface by using thickness we can get a solid body in part workbench.
- Draft analysing the obatined final out put.
Creating a tooling axis from the given class A surface using bisection method and analysing the given class a surface.
After visual inspection of the class A surface we can conclude that z axis would be the best possible way to create the tooling axis.
creating a intersecting line from the class A surface so that we can find the surfaces parallel to dummy tool which may create problem.
lines are extended from the points of the intersection which may create a problem while manfacturing.
By using bisecting line the two parallel lines were bisected to form a tooling axis,and analysed it using draft analysis.
class A and C surfaces joined together using join command
To create a closed thick surface the obtained surface been trimmed using class B surface.
The obtained closed body then thickened in the part work bench to form a solid.
Draft analysis on the solid surface.
- First by setting the view parameters to material we can further proceed to draft analysis , after positioning the compass on the tooling axis we can get the draft anlysis.(min draft required for the component is set to 3mm)
- Green region in the draft analysis indicates that the component has a minimum draft of 3mm
- Blue region indicates no draft or negative draft.
- which maens the component cannot be manfacturable or it will create problems while manfacturing.
draft analysis of the obtained part from the closed surface.
TO extract Ribs for the door handle , sketch must be created by considering the design rules.
Ribs extracted from the sketch then trimmed using a refrence surface.
Further the extracted ribs thickened in the part workbench and applied draft of 0.5 degrees on each face .
intersection shows ribroot thickness of the obtained part.
TO extract screw boss for the door handle , sketch must be created by considering the design rules.
Further extruded using pad in part workbench ,then applied fillet.
