Week 9 - 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 draft angle requirements and performing the Draft analysis on the model at the end

TOOLING AXIS

From the given Class A surface we can start with checking the connectivity of the Class A surface, ensure that there is no gap between the component Using join command we can visually check it or by clicking boundary command.It has 3 boundaries one outer and two inner circle boundariesTherefore first check completed.

The next step is to creating TOOLING AXIS, The tooling axis is nothing but the mould opens or cavity opens.Check visaully which is the best possible tooling axis and check all three axis. Along x it possible but expensive and y is not possible. z is the best possible tooling axis.

First create a line throuhg the hole in Z direction by creating a point and it is called as Dummy tooling axis, then create a plane in the point and use intersect tool then we can get intersection and we can draw two parallel line to the Dummy tooling axis and then we can find the bisecting ling, it is the real Tooling axis

BISECTING METHOD

Bisecting method is basically use to find the proper tooling axis using the dummy tooling axis. In Bisecting method, bisecting line is used which either bisect the two line or it will show error which means the two lines are parallel to each other. In order to know whether the particular surface is toolable or not we intersect the surface with the respective plane and get a sketch which consist of two lines and with the help of bisecting line option we bisect the line which creates a line at the mid point of the two lines. Like wise we create tooling clearing axis for x and y which will be used to create the main tooling axis using the bisecting line option in in the line comand.
