Week 9 - Project - Master Section Development

MManas Patil8 Mar 2022

AIM: To develop the solid plastic component from the given master sections along with the engineering features and also perform the draft analysis.

REPORT:

Examine the given inputs i.e. the master sections and the class A surface to develop the component
To create the tooling axis extract the opposite faces from the two master sections provided
Form a bisecting line using these faces and we would get the Tooling Axis
The next step is to create the Class B Surface for that offset the class A surface by 2mm
Now we need to create the flanges following the master section
Extract the edges to with the flanges are to be connected and sweep it
Match the sweeped surface with the master section and we would get the Flanges
Offset the flanges and trim it with respective class A & class B surfaces
Class A with flange:
Class B with flange:
To obtain the Class C Surface create boundary for class A surface with flange and sweep it with 3° draft
Then trim the C surface with class A & B and join them to form the final component
Then use closesurface command to add thickness and form solid component
The next step is to create the attachment features for this we need to follow the master sections
To form the dog house refer the master sections and sketch the profile then extrude it
Provide thickness to the walls and give 0.5° draft on faces
Ensure that doghouse wall thickness at the intersection of the part wall ( C ) should be 40% or less than the main wall stock ( T ) also height of ( B ) should be between 3.0 – 6.0
For the creation of locators sketch the profiles for 4-way locators and pad them with thick feature
Provide 0.5° draft on their faces and also give chamfer and fillet on the edges
Sketch line profile for rib and create ribs 50mm apart using extrude and thicken commands

Draft Analysis Report:

We need to perform draft analysis on both the class A and solid component
For the draft analysis go to Insert-Analysis-Feature Draft Analysis and make sure the view mode is on material
Inline the compass with the Tooling Axis and lock then click on the solid part we will get the draft analysis
When we click on the part it will turn green that means the required draft angle is maintained
We can change the value of draft angle from the colour scale table and the model will change the colour accordingly
We can also analyse the draft at a particular point on the body by moving the mouse cursor on the surface
