Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

LOCATOR AND HEAT STACK DESCRIPTION

TOOLING AXIS :-Tooling axis is created along x,yand z direction, to choose the best tooling axis out of it for reducing the tooling cost.this tooling axis is decides the movement direction of core and cavity to manufactur the door arm rest part.

DRAFT ANALYSIS :-The draft analysis command enables you to detect if the part you drafted will be easily removed. this type of analysis only based on colour ranges identifying zones on the analysed element where the deviation from the draft direction at any point ,corresponds to specified values.

draft analysis is carried out to check the draft in the class A surface of arm rest is feasible .the normal draft for plasitc components is 3 degrees and 0.5 degrees is the minimum draft value.

B SURFACE :- B surface are said to be engineering surface which has all the fixing elements in it this b surface created with reference to the given class A surface.

C SURFACE :- C surface is said to be the connecting surface of class a surface with b surface

CLOSE SURFACE :- after creating of class A,B AND C surfaces they are joined and trimmed to from the closed surface fully enclosed surface with out any gaps.

HEAT STAKES :- Heat stakes is also a type of attachment feature of the plastic components which is used to fix the components together perfmantly by plastic welding. the heat stakes are the protrusions on the b surface which is used weld the components by controlled melting or heated tips .

STEPS INVOLVED IN HEAT STAKE CREATION :- after creating the part ,positioned sketches were created normal to the part according to its requirements.

then these sketches are padded along the tooling axis with a height which is enough to go over the bottle holder flanges and translated to the reqired positions.

after padding the inner and outer sides are drafted along the tooling axis with 0.5 degrees and the reqired edges were filleted.

all heat stakes created are assembled and then union trimmed with arm rest part by using boolean operations.

some ribs were created to support the heat stakes to certain height .

the same procedure is followed to conduct draft analysis on the solid part of the heat stakes .

LOCATORS :- Locators are type of attachment feature of the plastic components which is used to arrest the degrees of freedom of the component to help its fixation. locators are in two types, they are 2 way and 4 way locators

STEPS INVOLVED IN LOCATOR CREATION :- After creating the part ,positioned sketches were created normal to the part according to its requirements .

then these sketches are padded along the tooling axis with a height which is enough to go over the clearance panel to the reqired positions

after padding its sides are drafted along the toling axis with 0.5 degree and reqired edges are chamfered and filleted .

in completion of locators creation,some boolean operations are used to assemble and union trim the locators with part body .
