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

HEAT STACKS AND LOCATOR ON DOOR APPLIQUE

LOCATOR

Locator is a part that is used to arrest the degrees of freedom for a part
The locator can be of any shape if until it satisfies the requirement
The locators used in this exercise are 4-way and 2-way locators
4-way lacators are used to arrest the x and z axis moment and rotation
The 2-way locator is used to arrest the y axis rotation
The locator is created by creating a positioned sketch
Then, the sketch of the locator is drawn and then it is thickened using pad command
A thickness of 1.3mm is given to it
A draft angle is given with respect to the tooling axis (0.5°)
It is given an entry chamfer of 3 mm and filletted
Now, the second 4-way locator is recreated by copying the first locator and pasting it with the link
And then it is trasnlated to the other end of our convenience
The 2-way locator is created in the same way

HEAT STACKING

Heat stack are points that help in arresting only a certain degree of freedom
In this case, it is used to arrest the Y-Axis movement
They are small cylinder like protrusion that are pressed to lock the parts together
This is similar to rivetting process used for metals
First, the boundry is extracted on both ends of the part
Then multiple points are placed for the number of stacks placed
A posotioned sketch is created on the point and the drawings are done
It is then thickened using pad command and trimmed to the Door applique
The remaning stacks are copied and pasted and then trasnlated to the corresponding points created
The necessary holes are created on the door panel for the locators and stacks to come out
