Week 8 - Challenge 5 - Door Trim Lower

AIM

To Create the Door Trim 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.

Take the Thickness of the component to be 2.5 mm

Explainations :

Class A :

in this challeges we got the catia part file which is having the A class surface we only change their name and color before that look all body is pefectly close as well as no any impurity in surface after that create class B

Procedure Creatation of Toolinf Axis, B surfaces , C surface & Close Surface :

Tooling Axis :

Here first we required tooling axis for draft analysis. tooling axis is works as provided to direction for injection moulding as well as direction of draft angle where is check it right or wrong so 1st we extract the surface of class A and than create point on it use this point we create the line by using line command for proper direction which want to the draft analysis and this line knows as the tooling axis.

B surface :

here we just offset the Class A surface and get the B surface body here we offeset the 2.5mm value so we get the thickness is 2.5mm is mention in above so we offset the A surface for 2.5mm

After extracting the A surface, there are some impurities in extracted B surface. We have to sove it using commands such as multiple extract,join,fill,curve,fillets etc.

Class B surface

C surface :

c surface creation by using the sweep command so 1st we create a boundary than disassemble get two curve 1st out-side surfaces than second is in-side surfaces after that we used sweep commat in that goto draft section on choose surface reference option and sweep it similar think done inner curve than we get c surface

Close Surface :

After that join Class C surface to Class A and trim it with the Class B surface to get the closed surface. Then make it into solid surface using Solid Command.

Draft analysis of closed sirface.

here we goto the draft ananlysis and 1stly we required direction so used tooling axis so we drag the compass and properly mounting on tooling axis than fix it after that goto analysis and get the results here we see that green means draft angle greater than the required angle value and above figure shows the draft analysis results.
