Week 10 - Challenge 2- Attachment Feature Creation (Dog House)

AIM:

• Write A detailed report explaining the draft analysis of class A surface,final component and engineering features
• An explanation should be given on the way of creating the tooling axis, particularly the Bisecting method

given class A surface

Tooling axis

It is defined as the direction in which the core and cavity open. Here I created tooling axis using the bisecting method. Selection of the direction of the tooling axis depends on the ease at which components can be easily ejected

Steps to create tooling axis

• Create a point on class A surface, And create a plane on that point now creating an intersection on a that plane with the class A surface                                                                                                                                          

• Using the intersection, lines will be created along the inclined walls, these lines are used for creation of tooling axis by bisecting method where the two lines and point will be selected as inputs. Name this line as main tooling axis

                                                                            

Draft analysis

class A surface

Before going to drat analysis go to customized view parameter >under mesh >check material and then click ok.

• Now for draft analyses go to insert » analysis » feature draft analysis.
• Use the compasss to define the draft direction.
• Nominal draft considers is 3 degree

All areas are within minimum draft of 3 degree except the area show below

 here minimum draft is -0.98deg

 minimum value of draft at this area is -1.93 deg

 here draft value is 2.39deg

 class B

since class B is the offset of class A surface hence the errors occre in class A will also occure in class B 

 minimum value of draft at this area is -0.98deg

 here draft value is -0.937 deg

 draft value is 0.83 deg

class C 

All areas are within minimum draft of 3 degree

     

draft analysis of dog house with resepct to tooling axis and side core axis

outside surface of dog house will be cleared by main tooling axis but to clear inside surface of dog house in draft analysis we need to create side core axis

nominal draft consider is 1.5 degree with tooling axis and 0.5 deg with side core axis 

all areas are within nominal draft of 1.5 wrt tooling axis

    

all areas are within nominal draft of 0.5 deg wrt side core axis
