Week 9 - Project 1 - Door Trim Lower with Engineering Features
AIM:
To create Plastic design and attach the Engineering features and generate the Draft Analysis for the given the model.
PROCEDURE:
Create a point at the center of the surface by using Point Definition by : Point Type - on surface ,Surface - select the surface and Distance - 0
By using the Line Definition option create a line in Y direction by : Line Type - Point-Direction, Point - select the point and Direction - Y which will be the Main Tooling Axis
Do the draft analysis on Class A surface.
CREATING B-SURFACE FOR DOOR
Extract the Class A surfaces by selecting the surface to extract and Untrim the surfaces by selecting the surfaces which are required and offset the untrimmed surfaces by selecting the surfaces to offset to a distance of 2.5mm and then trim the surfaces.
Fillet the surface with a radius and extrapolate the surface.
CREATING C-SURFACE FOR DOOR
Extract the Boundary of Class A by Extract option and Using Sweep option create the Class C surface.
Smooth curve the extracted boundary and then in Sweep option : Type - With draft direction , Guide Curve - Boundary and Draft direction - Tooling axis and angle as 3 degrees.
After creating the C surface,join the Class A and Class C surface by Join option and then trim it with the B surface.
Part Design,fill the surface body with the solid using Close surface.
ADDING LOCATORS 4 WAY
Create a point at the center of the surface of Door Attachment by Point Definition.
Create a plane on the surface at the center by Plane Definition with reference to the Point which was created and then create a sketch of a 4 way locator on the plane.
Pad the Sketch in Part Design, in Pad : Type - to surface , Limit - select the surface as limit and Profile - Sketch and in Pad tick mark the “Thick” option and then click the more option and select the Neutral fibre and the thickness 1 should be 40% of the main wall thickness.
Draft the faces of the padded area by Faces to draft - select the faces to draft , Neutral element selection - select the base surface and pulling direction - Tooling axis.
After drafting the faces,chamfer the edges at the top and Objects to chamfer - select the edges , Mode - Length/Angle.
Fillet the edges and faces.
ADDING HEAT STAKES TO DOOR
Now create a sketch on the point created on a Parallel curve.Draw the circles with diameters of 5mm and 7mm and in Part Design,Pad it : Type - to surface , Limit - select the Class A surface.
Copy the Part body of the Heat Stake and Paste it Special with reference link and then Replicate to the points which are created by Translate option : Vector Definition - Point - Point.Translate the part body of Heat Stake to the other point which was copied by selecting the start point and endpoint.
By Boolean operation,Assemble all the Heat stakes part bodies in a single body and then Unitrim the Heat Stakes with the Solid body of Door Applique by selecting the faces to keep.The distance between the tip surface of locator and Door Attachment surface should be equal for all locators.Also the height of Heat stake should be smaller than the Locators.
Finally do the Draft Analysis for the final component
