Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)
Tooling axis
The tooling axis can be created by using differnt metods like biscuting method and by using point and direction and also normal to surfce method.
Tooling axis shows taht in which way that core and cavity is opened.
It also hepls to ensure the draft angle.
Draft analysis of class A
The draft analysis made to make sure that the part can be manufactured.It also ensure draft angle is rom 1 to 3 degree.If teh draft angle is more the part cannot be manufactured.
Draft angles are very important in thermoforming product design. If the product is formed onto a negative mold, it shrinks away from the mold sidewalls. As a result, negative products can be thermoformed with vertical walls having zero draft angles.
With draft angle the part can be ejected easily from the mold.
Draft analysis is very importnt to check the part can be manufactured.
Class b surface
Class b surface is created where some of the paths are missing also the gaps between the surface are filled.
Class c surface
Class c surface helps to join both a and c surface
Join of class a and c
The join and a and c helps to join a and b surface to the required thickness for the component.
Final trim
The final tri is done by joining both a and b surface.
Final trim draft analysis
Ribs
Ribs helps to increase the the strength of th part.
The designig rules to be followd while designing ribs are
Thickness,height of the rib,location,Quantity,Manufacturability.
Whiile designing ribs the draft angle should be given properly.
A draft angle of 0.25-2 degrees, with 0.5-1 degrees being the most commonly used, should be applied to each side of the rib
Rib design
Screw Bosses
The screw bosses are also similar to the rib used to increase the strength of the part while ribs uses more material while screw bosses use less material.

1.draft
2.Thickness
3.Height of the diameter hole
