Week 8 - Challenge 1 - Base Bracket Design
AIM:
To Create the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.
REPORT:
Given class A sufrace:
STEPS:
- Check the connectivity of the Class A Surface .Ensure that there is no gap between the component, using join command check it or by clicking boundary command.
- Find the possible tooling direction for the given component,it is the direction of mould(core or cavity) opening and closing.
- NEXT FIND THE DRAFT ANALYSIS,DRAFT IS required on all the parts in the direction of mould movement in order to allow parts to release (or) eject from the molds properly
- DRAFT NOMINAL VALUE:3 degree is the nominal value,7 degree for textured faces
- colour ranges in draft vanalysis
green-draft above 3 degree
red-below 0 degree
blue-0 to 3 degree
Draft is providing angles or tapers on the product engineering features such as ribs,screw bosses,that lie parallel to the direction of release from the mould eases part ejection.
The draft is done based on the tooling direction
