Week 9 - Challenge 3 - Bumper

OBJECTIVE

Create a tooling axis in proper way for finding better draft analysis from given class A surface. Create draft analysis of class A surface and create class B and class C surface from class A surface. And finally create draft analysis of finished body.

TOOLING AXIS

Tooling axis or tooling direction is main consideration for plastic part and mold parts because it defines movement of mold part and possibility of plastic part to come-out from mold part (Core and Cavity). In Molding machine arrangement is given to open the mold along a direction which is known as Tooling Direction. The mold is built from two separate halves (Core and Cavity) and tooling direction basically define the direction of mold pulls apart. Tooling direction is known as primary direction.

• Here created a tooling axis. First of all I extract a base surface and create a mid pont on it. And then I create a line through this point with perpendicular to base surface. And then I performed draft analysis ans I saw every thing is ok. Then finally it is my tooling axis.

DRAFT ANALYSIS

The Draft Analysis allows the user to easily analyze a part for proper draft angle. A Draft Angle describes the amount of taper for molded or cast parts perpendicular to the parting line. Draft Analysis is applicable for 3D part models. To create a draft analysis for any 3D part file, the user needs to select part/surface select the pull direction. You can change the pull direction.

CLASS A SURFACE

It is the aesthetic surface and the outer surface. The Class A surface is given as input to the plastic designer to create the plastic component.

CLASS B SURFACE

The offset from Class A surface is used to produce the class B surface. Offset the given Class A surface downwards to 3mm. There will be certain patches in the offseted surface, close all the surfaces using multi-section surface.

CLASS C SURFACE

This is the surface that connects the class A and B surfaces together. After joining surfaces together check the draft analysis on the final component, convert the component into a closed surface.

CLASS A & B

FINAL TRIMS

CLOSE SURFACE

Import the final component on the part workbench, defines the part body and do close surface operation on the final trim.

• FINAL DRAFT ANALYSIS
• Perform Final Draft Analysis on the plastic component. Enable the tooling axis and enter the axis system on the tooling axis and analyze the draft on the surface
