Week 8 - Challenge 1 - Draft Analysis on a Fan Cover
AIM : To Create the tooling axis for the given Fan cover model meeting the requirements of the draft angle and perform the Draft analysis on the model.
PROCESS :
*Drafting analysis has to be done to measure the angles of different surfaces.
*This helps us to get mould parts with accuracy.
*The given model is checked for any open surfaces.
*Next the surfaces are joined together.
*To do drafting , it is necessary to generate tooling axis. The axis has to be perpendicular with respect to surfaces.
*The angles of surfaces are measured with respect to tooling axis. Maximum angle be 90 degrees.
*In the image below intersection is taken and bisect is given to generate tooling axis.
*Reference planes are taken as xy & yz.
* Insert - analysis - draft analysis is selected.
*The degrees are set.
*In the display option select 'analysis under running point'.
*Place the cursor on any surfaces to see the angle. Here the angle is seen to be 9.2 which falls under criteria with respect to assigned angles.
*As we could see, if the minimum value is changed to 10, one of the surfaces is visible in red. This means that the product has failed to clear based on angle specification.
