Week 8 - Challenge 4 - Bumper

The draft analysis is given to body inorder to avoid the scratches on the surface due to friction, also it allows for the part to release from the mold easily.

The minimum draft angle is given 0.5 degree and upto 3 degree is accepted.it is given with respect to tooing axis.

Drafting is done on C surface which connects A and B surface.

The Draft Analysis allows the user to easily analyze a part for proper draft angle. A Draft Angle describes the amount of taper for molded or cast parts perpendicular to the parting line.

during drawing, Initially we have given the A surface. First step is to draw the tooling axis by finding the most appropriate direction and using the bisection of tooling axes along X and Y direction by intersecting method,if needed. By inersecting the a suface and a plane , we get the line along it. we can give the drat angle on a body if there is large flat surface or on a circular hole if any.

In Bumper we created the tooling axis by simply extracting aa surface which is planar in nature and create a point on it in zero cordinates. then we create line along the x axis on the inserted aaxis system at the point.

This is then named as tooling axis. and with this tooling axis we check the draft analysis with a surfaace and ensyre the angle is greater than 3 degree.
