Week 8 - Challenge 1 - Draft Analysis on a Fan Cover

DRAFT ANALYSIS ON FAN COVER 

CLASS A MODEL

                             

 

* Before start doing the axis sysytem for the Class A surface we need to check the given Class A model is correct.  Whether the all the surface are connected. It can be checked through JOIN command and BOUNDARY command. 

                                     

 

DEFINE THE TOOLING DIRECTION

Next we need to find the exact toooling direction to clear all the face section of the surface. So check through all the possible way of doing in a single main tool.

                          x direction                                                                                              y direction                                                                                              z direction

                                                                  

 

In the above all 3 direction we come to know that x and y axis are not able to  clear top hole surface , We need to use separate side core to clear the top hole surface which will increase the cost of the component. 

In the z direction it was clearing both side and top faces in a single main tool axis. So we are taking the tooling direction towards z direction. So create an dummy tooling axis in z direction for refrence.

 

           

BISECTING LINES

Next create a interfrence line through xz and yz direction and create a line for a parallel side face then create a bisecting line for each x and y direction. Then bisect the both the x and y tooling axis create a tooling axis for z direction.

XZ DIRECTION

  

 

YZ DIRECTION

    

TOOLING AXIS Z DIRECTION 

 

DRAFT ANALYSIS

To get into the draft analysis go to insert-analysis-feature draft analysis

 

Before switching to the draft analysis make sure the part model mode is in material mode by selecting through the customize view parameter section.

Next select the compass mode , drag the compass near by class A surface and merge it to the tooling axis direction.

      

Now select the model, draft analysis feature is applied while the model shown as green colour. While blue color indicates the inverse draft direction.

   

Draft angle limit can be identified through the colours shown

This pic show as the total draft analysis angle and colours. And also we can check the draft angle of surface at any point.
