OBJECTIVE:Create the Bumper Plastic component through the given Class-A surface.

GIVEN CLASS A SURFACE:

Thickness of the component is 3mm.

METHODOLODY:

1.TOOLING AXIS CREATION

Tooling axis is the direction in which a core or cavity of mold opens. This Axis is very important to determine the orientation of the component in mold, core and cavity design.

In this case the tooling axis is created by,

Check in which direction the component tooling axis is going to create.in this case the x axis direction is more suitable to create an tooling axis.

Create an point on the curve.

An line is created through the point , the line considered asdummy tooling.

To check the tooling axis is right or not use draft analysis.in this case the tooling axis clear the draft anaalysis do the created dummy axis is considered as the main tooling axis

2.DRAFT ANALYSIS OF CLASS A

The draft angle is the amount of taper perpendicular to the parting line for molded or cast parts. It is measurable in degrees. Because plastic shrinks and sticks on molding surfaces as it cools, we draft the walls of the plastic part so that it ejects or breaks free from the molding surfaces more easily and without dragging. To reduce the risk of damage to the elements and ensure ejection, a functional injection molding part must have drafts on both the cavity and core sides.

PROCEDURE:

First change the created part into material.
Click on the compas and plase in the tooling direction.
Use the lock command to fix the compass
Click on the surface and apply the draft angle(minimum draft angle is 3 degree)

3.CLASS B SURFACE

The A-surface is offsetted by 3.00mm as it is the thickness required.
The Areas where the B-surface has issues are corrected by closing them using commands like Multi section,Sweep,Offset and extract.

4.CLASS C SURFACE

The A and B surfaces are connected by another single surface which is called the C surface
Class c is created using sweep command.
The sweep is done with draft direction and in some area using the referance surface.

5.CREATION OF SOLID BODY

The solid body is created using close surface feature.
Boundary is selected and the body is picked. Since an error popped up it can be understood that all surfaces are joined with each other to form a proper closed surface body.
