Week 9 - Project 1 - Door Applique Design with Engineering Features

AIM : To create Door Applique Design with Engineering Features

Door Applique

Door Attachment Feature

PROCEDURE:

1. Check the continuety of class A surface by using Boundary command.
2. Create a point at centre of the surfaceusing point definition: Point type - on surface. Select the surface and distance= 0
3. Create a Line at point along Y axis: Line type - Point direction. This line will be the main tooling axis.

4. Perform Draft analysis on class A

Creating Class B Surface for Door Applique:

1. Extract the class A surface by selecting surface to extract and untrim the required surfaces and offset the untrimmed surfaces to 2.5 mm and them trim the surfaces.

2. Fillet the surface with radius.

Creating C surface for Door Applique:

1. Extract the boundary of class A by extract option and using sweep feature create class C surface

2. Smooth curve the extracted surface then sweep. Type : with draft direction, Guide curve :Boundary and draft direction, Tooling axis and angle 3 degrees.

3. Create the C surface for 2 boundaries seperately.

After creating class C join Class A and Class C and trim it with Class B

Close Solid Body

In part workbench, Fill the surface with solid using close surface

ADDING 4 WAY AND 2 WAY LOCATORS:

1. Create a point at centre of surface of Door attachment

2. Create a PLane at the centre by plane definition with refrence to a point and then create a sketch of 4 way locator on the plane.

3. Pad the sketch. Pad type - to surface, Limit - select the surface as limit, Profile - Sketch and select Thick option. More option - Neutral Fibre and Thickness 1 should be 40% of main wall thickness.

4. Draft the faces to be padded area by Faces to draft - select faces to draft, Neutral element selection - Select the base surface and pulling direction- Tooling axis.

5. After Providing draft, Chamfer and Fillet the required faces.

6. Copy the part body of the 4 way locator and paste it special with reference link and then translate it to the other side by coordinates by Translate option : Vector definition - Coordinates

7. Now create 2 way locators at below the centre by creating the skertch and repeat same procedure of padding, Drafting, chamfering and filleting.

8. By boolean operations, Untrim the locators with solid body of Door Applique by selecting faces to keep.

ADDING HEAT STAKES TO DOOR APPLIQUE:

1. Offset the class A surfae to 2.5 mm and extract the boundries of offsetted surface.

2. Parallel curve the extracted boundries

3. Give Point repeatations to the Parallel curves. No heat stahes should be present nearer to the Locators.

4. Now create a sketch on a point created on parallel curve. Draw two circles of dia 5mm and 7mm. Pad it.

5. Copy the part body of Heat stakes and paste it Special with refrence link. and then replicate the points which are created by translate option.

6. By boolean operation, Assemble all the heat stakes in the single body and then Untrim the Heat stakes with the Solid body of Door Applique.

7. The distance between Tip of the locator and the Door attachment surface should be equal for all locators. Also the height of heat stakes should be smaller than the locators.

THICKEN THE DOOR ATTACHMENT SURFACE AND CREATING CLEARANCES FOR LOCATORS AND HEAT STAKES:

1. Thicken the Door attachment surface by2.5mm by using thicken option

2. Now from the Locator sketch copy the sketch into new geometrical set and then draw a circle of 15mm and make the old sketch as constrution line where we have to make clearance for Locators.

3. Pad the circle to an offset distance below the door attachment surface and draft the surface to 0.5 degrees.

4.By Boolean operation, remove the pad from the Thicken surface. So the clearance gap between the locator wall and clearance wall should be 0.1mm to lock the motion.

5. Do the same process for remaining locators and heat stakes by creating the Clearance gaps where the clearance gap for heat stakes should be 0.5mm.

6. Finally perform Draft analysis for the final component.

Result:

Created the Plastic design and attached the Engineering features and generated the draft analysis for the given Door Applique Class A model.
