Week 8 - Challenge 1 - Draft Analysis on a Fan Cover

ANSWER:

Create the tooling axis for the given Fan cover model meeting the requirements of the draft angle and perform the Draft analysis on the model.

What is the draft?

it is defined as a modeled parts to make thwm easier to remove from molds. there are two of determining the objects to draft either by explicitly selecting the natural element,which makes the application detect the approximate focuses to use

major industries use the minimum draft angle is 3 degrees.

PROCESS:

First we check the continuity of the given first class -A surface

check the directiopns (X.Y,Z) axis and finally we decoded which is the best possible direction to produce a mold that direction of the axis is called dummy tooling axis

a fan with several drafted surfaces that is oriented in a part location that the draft analysis initially assumes z-axis direction

in z-z axis direction the faces are either positive or negative draft . so that the z- axis we have taken as the summy tooling axis we nees to crate to a perfect tooloing axis.

PROCESS:

TOOLING AXIS defined as thr direction in which the mold opens or closes the core cavity

create an axis system on a ppoint.

create an intersecting line on zx plane and a cass-a surface

Pulling direction: The direction corrssponds to the reference from which the draft faces are defined

Draft angle: this is the angle that the draft faces make with the pulling direction . this angle may be defined for the each faces

Parting element: this plane, face or surface cuts the partin teo and each portion is drafted accordingly to its previously defines direction

Neutral elemnent: this element defines a natural curve on which the drafted face will lie. this element will remain the same during the draft the neutral element5 and parting element may be the same element
