Week 8 - Challenge 1 - Base Bracket Design
Aim : 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.
EXPLANATION ON BISECTING METHOD
Bisecting system is principally use to find the proper tooling axis using the dummy Tooling axis. In Bisecting method, intersection line is used which either intersect the two line or it'll show error which means the two lines are parallel to each other. In order to know whether the particular face is toolable or not create intersect line with the help of plane and get a sketch which correspond of two lines and with the help of intersecting line option we intersect the line which creates a line at the middle point of the two lines. we produce a tooling axis for x and y which will be used to produce the main tooling axis using the intersecting line option in in the line command.
STEP 1 Check the connectivity of the Class A Surface insure that there's no gap between the element, using join command. We can visually check it or by clicking boundary command. It has 3 boundaries one external and two inner circle boundaries.
STEP 2 : Find the Tooling axis of the element. The Tooling axis is nothing but the mould opens or Cavity opens. Check visually which is the possible Tooling axis axis. Check all three axis.
Along x it possible but precious and y isn't possible.
z is the possible Tooling axis.
Creating a Tooling axis along z
thus the main tooling axis is along z axis. Now perform the Draft analysis using the Featured Draft Analysis tool in the tools. also after opening the draft analysis tool box go for the compass and place the compass aligned to Tooling axis and click on the cinch symbol after aligning and further click on the surface.
Now creating Class B Surface
Initially Extracting the right side Rib using extract option from Class A face. also perform Extrapolate in order to increase the length Now trim the Surfaces to needed surface also neutralize the surface in order to get the needed offset Similarly produce the left side Rib,
Now get the slanted as well as the flat face and neutralize it to asked value And now trim in order to get the needed face Now fillet the face to a needed thickness
Now Create Class C surface by using sweep tool
