Week 11 - Final project
FInal Project Report
The Door Assembly can be divided as four parts
The door arm rest
The lowe substrate
The bottle holder
The upper part
Fistly started with the doorm arm rest
Class A surface is given. Firstly the tooling axis is created . As per the mastersection the class B should be created using offseting the class A Two times. Class C SUrface is then created using sweep and multisections
The final body is then obtained using triiming A+C with B surface and then it is made to a close body in the part design work bench
With help of mastersections Flanges are made by measuring the dimensions
Lower Substrate
First the tooling axis is made for lower substrate
The class b surface is obtained by ofsetting the class A surface by 2.5mm
The class c surface is then obtained by sweeping along class A surface and joined together with class A and tthen trimmed with CLass b surface
final body is then obatined and close body is obatined in part design
the draft analysis is taken
additional flanges and dog houses created using the mastersections and required dimensions
The upper substrate
The tooling axis is then created
class B surface is created using offsetting the class A
The class c surface is then created using sweeping class A
The class A+c Surface is joined
and final body is obtained using trimming CLASS A+C WITH class B
the thickness of the surface is 2.5mm
the final close body is obtained
the extra parts are crreated using mastersections
The bottle holder
The tooling axis is then created
class B surface is created using offsetting the class A
The class c surface is then created using sweeping class A
The class A+c Surface is joined
and final body is obtained using trimming CLASS A+C WITH class B
the thickness of the surface is 2.5mm
the final close body is obtained
the extra parts are crreated using mastersections
FINAL JOIN
The assembly is done using the push pin given
It is made coincident with the dog house
The dog House is an attaching part that help to attach the plastic part with the metal which is also a secondary use and it is mainly used to avoid sink marks
Heat stakes are used to attach to plastic parts. The dimension given for heat stake is 7.5mm outside dia and 4.5mm inside dia . The draft is given for .5 degree and edge fillet is .5 mm
