Week 9 - Project 1 - Door Trim Lower with Engineering Features

For Draft Analysis, Tooling Axis is required. So here we have to create center point on hole surface by creating boundary there, then have to fill that area.
From that center point, we have to create a normal line through that point in Y direction.
We choosen Y direction as in this direction we will able to see all parts of the component.
So in this way we get Tooling Axis in Y direction.

Once we get Tooling Axis, we can go for Draft Analysis. Click on Feature Draft Analysis tool and open it.
Ensure that our component in the material view mode. As we open Draft Analysis tool, we can able to see 2 boxes as shown in above image.
Click on compass, so compass will be seen to screen. Align this compass with Tooling Axis and click lock symbol and then on Class A Surface.
So surface get colour on it.
Green colour indicates that, draft angle is above the 3 degrees.
Red colour indicates that, draft angle is between 0 to 3 degrees.
Blue colour indicates that, draft angle is below 0 degrees or negative.

Class B Surface :
Its a offset surface of Class A Surface.

Click on Feature Draft Analysis tool and open it.
Ensure that our component in the material view mode. As we open Draft Analysis tool, we can able to see 2 boxes as shown in above image.
Click on compass, so compass will be seen to screen. Align this compass with Tooling Axis and click lock symbol and then on plastic component.
So component get colour on it.
Green colour indicates that, draft angle is above the 3 degrees.
Red colour indicates that, draft angle is between 0 to 3 degrees.
Blue colour indicates that, draft angle is below 0 degrees or negative.

4 Way Locator :
Its a component use to positioning the attachment component on the main component.

For design this Locator, we have created 2 crossd lines with 20 mm. Its like rib construction.
So, we have given thickness for it is 1 mm by using relation of 0.4 × thickness of main component.
Height, we have given as 12.5 mm by using relation of 5 × Thickness of component.
We have given Draft of 0.5 per side of Locator.
At 4 corner edges of Locator we have given 3 mm chamfer.
Then 0.3 mm of Fillet radius at all side edges of Locators and 3 mm on upper edges.
In this way, we have restricted 11 degrees of freedom for locators and only one translation degree of freedom we have kept for positioning the locator on main component.

Heat Stake :
For joining the 2 dissimilar or similar materials with each other by means of melting the created portion of attachement component on the main component.
There are many advantages of it, like reduce machinery cost, Time saving and economical.

For designing this Heat Stake, we have created circle with 5 mm diameter.
By using relation of thickness of wall, 0.6 × Main component thickness. So we get 1.5 mm, then by giving wall thickness per side, we created of 8 mm diameter circle and then give pad to it.
Its construction is like a Screw Boss, so for height we used relation of Diameter to Height ratio of 3:1, but in this way height of Heat Stake we get as 15 mm, which goes beyond the height of Locator. So we have given 5 mm less height to Heat Stake as compare to the Locator for do fixation after the positioning. So here we have given height to Heat Stake is 7.5 mm.
Then we have given 0.5 degrees of draft inside and outside of this heat stake.
