Week 9 - Challenge 3 - Bumper

AIM : To create the bumper design plastic component through the give class a surface. create the tooling axis for the give class a surface  by meeting the requirement of the draft angle and at the end perform the draft analysis on the model 

INPUT GIVEN : To create the bumper design plastic component through the offset class a surface using 3mm thickness of class b surface

 TOOLING AXIS :Tooling axis is defined as such all the featres of the part can be manufactured easily. so here we followed the below steps to create the tooling axis.
 Create a point between the corner most edges of the bumpeAxis is created on the point intersection is taken with class A and Axis Sketch is drawn on the intersection curves.Two lines are drawn at the outmost ends.Both the lines are bisected and a line is created at the middle.

DRAFT ANALYSIS :

• Draft is done on the Class A surface. 
• Change it to material in customise view.
• Click the Draft analysis tool and click the surface and align the compass to tooling axis.
  3 degree is the clearing angle
• So here is photo of cleared (Green) draft.

CLASS B SURFACE CREATION :

• B surface is created by using the given Class A surface.
• Join all the faces except the filletsSo we get separate 4 parts
   Offset to 3mm beneath the class A surface.
• All the 4 faces are offseted.
• Boundry is taken and the below shown edges are extrapolated. 
• The extrapolated faces are trimmed.
• The edges are given with fillets so that the 3mm is maintained
  Hence the B surface is formed.

CLASS C SURFACE CREATION :

• Class A boundry is taken.
• Boundry of the A is taken.
• Sweep is used to form the C surface.
• Be aware of the draft limit and make the sweep accordingly
  Join the segmented parts to get a whole C surface

CLASS C AND A JOINING AND C AND A TRIMING WITH B SURFACE :

• Surface C and A is joined.
• Surface B is trimmed with C & A.

DRAFT ANALYSIS :

• Draft is done on the Final Part. 
• Change it to material in customise view.
• Click the Draft analysis tool and click the surface and align the compass to tooling axis.
  3 degree is the clearing angle
• So here is photo of cleared (Green) draft.
