Week 12- Final project

FINAL PROJECT - DOOR TRIM

:TO create individual tooling for the parts and perfrom draft and perfrom draft analysis on the class surface

:to create the class b and clas c surface from the given class a surface .

:to form a soild geometry by combining all the surface

:to decide an attachment strategy for the part and create engineering feature in reference from the master section provided

:to perform draft analysis on the solid part modal with all engineering features

: to assemble all the components together to obtain the final trim .

TOOLING AXIS : THE next step is to create the tooling axis for the part which will determine the direction in which the core and cavity of the mould will move .

DRAFT ANALYSIS : DRAFT ANALYSIS IS DONE THE CLASS A SURFACE after the tooling axis has been obtained .

CLASS B SURFACE ;after all the validation has been done the class b surface is created by offsetting the class b surface to a distance of 2.5 mm.

CLASS C SURFACE : the classs c surface which connects the class a and class bsurface is creeate by sweeping the boundary of the clas a and using the class a as a reference .

PART : THE FINAL TRIM is create by joining the a class and c and finally trimming it with the class b . the combination of class a, b,c is then converted into a solid with the aid of fill command in the wrokbench.

ENGINEERING FEATURES :

DOG HOUSE : The main two purposes of a dog house are to avoid sink mark and to house varius other engineering features like scrow boss , locatars , push clips etc .

HEAT STAKE : are used in thermoplatic to assemble two parts together by locally heating ND COOLING the plastic material and allowing it to refrom itself and act as a joint for the two materials.

LOCATOR: the main purpose of locator is to faciliate proper locking of two component together while assembling and arrest the mix degrees of freedom possible .

RIB: the main purpose of rib is to increase the stiffness of the part in certain critain critical area without adding much weight and complexity to the component .

FLANGE: flange were create on the arm rest with the reference dimension from the mate rsketch provided .a

FINAL ASSEMBLY : the final assembly of the door trim involved the insertion of the push clips into the dog house slots using the dog house central axis and axis of the push pin coincident relation was given .after which using contact constraint the push clips were made to sit in the dog house slot as required .
