Week 8 - Challenge 1 - Base Bracket Design

                                                                        Base Bracket Design

Tooling Axis

The axis in which the mold or core and cavity is opens or the axis which the designer can modify or create a model by taking axis as a reference is called Tooling Axis.  

Procedure to creat tooling axis.

• Checking the Class A Surface, for to check which is the perfect place to create a tooling axis.
• By selecting hole as a reference surface creat a point useing the point type circle/sphere/ellipse in the centre of the hole.                                                                                                                                                                           
• Creating the dummy tooling axis we can find the origenal tooling axis . By selecting the line and click on point-direction option and create a line in Z- Direction.                                                                                                                         
• Create a plane in xy-direction by taking point.1 as a reference and intersect plane to the Class A Surface.                     
• Create two lines on the rib 1 and rib 2 useing intersect plane.                                                                                       
• By Bisecting line 2 and line 3 with the point 1 we get the Tooling Axis and publish that tooling axis.                               

Draft analysis

Draft analysis is a method to check the draft angle of the model in various faces and to creates draft on the surface to reduce the friction in the Ejection process.

Procedure to Draft analysis

Draft analysis 1

In draft analysis 1 we taking Class A Surface  to draft.

• Check the view mode and change it to material mode.
• Select the draft analysis tool in the tool bar and select Campass in the Direction option of the draft analysis tool. Then move the campass on the tooling axis at draft direction and lock the draft direction.                                                       
• Useing the running pointer we see the draft angle at different surfaces of the Base Bracket.                                            
• Then by useing the color scale option we can change the Draft angle.The green color shows if the draft angle is 3 degree,red shows if the draft angle is between 0 to 3 and blue shows the negative draft angle.                                       

Draft analysis 2

In draft analysis 2 we taking Final Solid surface  to draft.

• Select the draft analysis tool in the tool bar and select Campass in the Direction option of the draft analysis tool. Then move the campass on the tooling axis at draft direction and lock the draft direction.                                                       
• Useing the running pointer we see the draft angle at B surface and C Surface of the Base Bracket.                               
• Then by useing the color scale option we can change the Draft angle.The green color shows if the draft angle is 2.9 degree,red shows if the draft angle is between 0 to 2.9 and blue shows the negative draft angle.
