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 :
1.Tooling axis is defined as such all the featres of the part can be manufactured easily.
2. SO here we followed the below steps to create the tooling axis.
3.Create a point between the corner most edges of the bumperAxis is created on the point.
4. INtersection is taken with class A and Axis
5.Sketch is drawn on the intersection curves.
6.Two lines are drawn at the outmost ends.
7.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 :
- B surface is created by using the given Class A surface
Join all the faces except the fillets. - So 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 :
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 A AND C 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.
