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

DOOR TRIM LOWER-WITH ENGINEERING FEATURES

AIM:

  • To create the Door Trim Lower Plastic component through the given Class-A surface
  • To create the Heat Stakes and the locators considering the design rules mentioned in the video for the door

OBJECTIVES:

  • Sketches
    • Use Positioned sketch
    • Sketches should be Iso-Constrained
  • References
    • Use the given points in the model to create the locators and Heat stakes
    • Refer to the below-given image for more details
  • Tree Structure
    • Ensure Proper Tree Structure
    • Geometrical sets should have a proper name based on the sketches present inside of it
    • All the sketches should be created under the Geometrical set
  • Report
    • A detailed report should be done explaining the draft analysis and the tooling axis creation.
    • An explanation should be given on the way of creating the tooling axis, particularly the Bisecting method.

REPORT:

DRAFT ANALYSIS:

Draft analysis is done after determining the tooling axis,draft analysis is used to check whether the minimum draft 3 degree is maintained or not.Compass is used to define the draft direction if the minimum draft 3 degree is provided the whole component changes into green colour.

CLASS B SURFACE:

class-B surface is created by extracting each walls and un-trimming and extrapolating the walls to obtain the shape by trimming the excess surfaces and offsetting it to certain distance based on the thickness of the model.The offset surface will be the B-surface.

CLASS-C SURFACE:

The surface created using sweep command by sweeping the boundaries of A-surface along the tooling axis to connect from A to B-surface is nown as C-surface.Using the B and C surfaces created a closed surface will be formed by trimming the excess surfaces the surface will be converted into a solid model using closed surface option.

1) It is a tool that allows the user to ‘see’ whether the part they are designing can be removed from the tool being used to make it.

2)In the case of plastic injection molded parts it also allows the designer to see if there is enough draft on the part to ensure that it can be correctly grained.

3) we always use the tool with the axis direction method. Put the main axis on the draft direction line with Z being parallel to it. Select the tool then select the part body. You may need to reposition the axis again.

4) The results window has 2 options 1 with just 3 colour variants and the other with many variants. They can be edited by double clicking on them to give you the result you desire. The colours show the different draft angles.

5) We have to use following path for drafting anaylsis

Tools- Anaylsis- Feature draft anaylsis

6) At starting of drafting anaylsis we have to set compus which is show in direction row (2nd number option). During this w of compus is set towards the drafting angle.

7)After this we have to click on component. Now component become green as shown in below image and also if it become blue then flip direction of compus using flip option in direction row.

8) Finally set drafting angle at 0.5 degree and measure drafting angle at different faces of component by using display row.

9) If your component is green then drafting anaylsis process is completed.

Draft analysis is done after determining the tooling axis,draft analysis is used to check whether the minimum draft 3 degree is maintained or not.Compass is used to define the draft direction if the minimum draft 3 degree is provided the whole component changes into green colour.

CLASS B SURFACE:

class-B surface is created by extracting each walls and un-trimming and extrapolating the walls to obtain the shape by trimming the excess surfaces and offsetting it to certain distance based on the thickness of the model.The offset surface will be the B-surface.

CLASS-C SURFACE:

The surface created using sweep command by sweeping the boundaries of A-surface along the tooling axis to connect from A to B-surface is nown as C-surface.Using the B and C surfaces created a closed surface will be formed by trimming the excess surfaces the surface will be converted into a solid model using closed surface option.

TOOLING AXIS:

STEP 1:

connectivity of class-A surface:First checking the connectivity of the class-A surface,this can be done by creating boundaries or by using the join command and see how well it is connected.Just ensure there is no surface gap between component or surfaces.This is the first design step to check continuity and the quality of the class-A surface.

STEP 2:

Analyse visually for the best possible tooling axis for the component.Checking possibilities in all three x,y and z axis direction and finding what are the problem creation parts of the component.

The clearance checking along all the axis directions will be done by creating an intersection along an axis on plane with the model and constructing two lines contact with the walls,the lines bisecting the two lines and passing through the point will be tooling axis.

CREATION OF TOOLING AXIS:

Using the intersection,lines will be created along the inclined walls and as there is only one wall another line will be created at a certain angle to the wall,these lines are used for creation of tooling axis by bisecting method where the two lines and point will be selected as inputs.

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

Using the tooling axis created along x and y-axis,these are used for creation of tooling axis by bisecting method where the two lines and point will be selected as inputs.

publication is used to make easily accessible of the published components.
