Week 9 - Project 1 - Door Trim Lower with Engineering Features
Aim:
To create the Door Trim Lower Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.
Create the Heat Stakes and the locators considering the design rules mentioned in the video for the door applique.
Solution:
Downloasd the file ans save as catpart.
Class A surface:
The class A surface is given and the creation of class B and C are to be done
Creation of tooling axis :
The flat surface is been analysed and we can create a point is created and the line is created in Y direction.We use the draft analysis is been taken for the surface and the the green shows the toolling is done without any damage.
Creation Of Class B surface:
The Class B surface is been offseted fo 2.5mm for thickness of the material/surface.There will be some un offseted points we can use extrapolate join trim split and multisection solid etc for the creation of the surface.
Class C surface:
The class C surface is created by sweep operation of class A boundary and sweep with reference to surface and 90 degree fpor 3 or 4 mm the join the surface to the A class surface and then trim the surface to get the final surface.
Class C surface:
A+C surface:
Final Surface:
Solid model:
We change to part design workbench then insert a body n chose closed surface and click on okay
Darft Analysis of Solid model:
Design of locators and heatstakes:
LOCATORS:
The device to establish and maintain the position of the workpiece in work holders such as jig and fixture to ensure repeatability of work holder. The locating device for a work holding device mainly depends on the property of workpiece and the overall machining process.
4-WAY LOCATORS:
A round locating pin located concentrically in a hole is a common application of a 4-way pin, and helps to further secure the piece. 4-WAY LOCATORS: 4-way mean you prevent movement at 2 axes (+X, -X, +Y and -Y) on the plane. Generally, you have cylindrical pin on the fixture and circular hole at workpiece part.
Design :
We create a skecth for the 4 wqy locator and we givren them a minimun draft angle of 0.5deg and thickness according to the surface thickness
Can the skectch iso contrained so the padding is done easily.The make sure u keep a little lenght more for refernce during assembly we can correct accorinf to the surface we can easily copy paste the translate to different locations:
Heat stakes:
