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

Report

Draft Analysis is very usefull tool to analysis the draft value of plastic components as well as sheet metal components. In molding process, no part can ejected from the tool if it is having a straight 90 degree profile from its base surface.so, we provide small angle to each and every area of the component to get an easy removal of the component from the tool. Draft analysis technique is used to analyze whether our part model created in cad is manufacturable based on the draft condition applied.

In this Fan Cover components we check the draft analysis of given class-A part. for analysis draft firstly check the which plane is suitable for molding then after we draw tooling axis.

Process to draw Tooling Axis:-

• Pick the centre point of the circle by using piont command.
• Creat dummy tooling axis by using line comand.
• Intersect the class A along XZ Plane for checking which side effected the molding part.
• Draw two line that are paly major role during molding.
• Bisect two drawn line. Bisect line is called tooling clearing X direction.
• Intersect the class A along YZ plane for checking which side effected the molding part.
• Draw two line that are paly major role during molding.
• Bisect two drawn line. Bisect line is called tooling clearing Y direction.
• Bisect tooling clearing X direction line and tooling clearing Y direction line. This Bisect line is our Tooling Axis.

Class A Draft Analysis

After creating tooling axis, we perform draft analysis.Draft analysis workbench available in part design, Generative shape design, wireframe and surface for building and free style shaper workbench. Draft Analysis workbench available in Insert>Analysis>Draft Analysis. Firstly change the view mode to customize view parameter and select material option from the mesh and select material. After That Drag the axis simble and fited in the tooling axis. Two sub window pop up one is for draft deviation colour bar and second is menu bar. Green colour part represent ok for manufacturing. We check all part part with different view all are green that mean ok for molding.
