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

AIM

To 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 in CATIA V5

SOFTWARE USED

CATIA V5

DRAFT ANLAYSIS

Draft analysis in catia is a command that is used to detect if the part you drafted will be easily removed from the mold. it is performed based on color ranges identifying zones on the analyzed element.

Most of the industries is using minimum draft angle is 3 degree

PROCEDURE

• Check all the boundary whether it has connected or not.
• Check the model visually & choose the best tooling direction which should be easy for draft

• After analyzing from the above model the best tooling axis is z direction.

CREATING THE TOOLING AXIS

• Create a point 1 and insert a axis system on the point 1 as shown below

• Create a dummy tool axis on z direction using point – direction

• Create a intersection on zx plane for the given surface

.

• Create a point to point line as shown below

• Add bisecting line as shown below by the reference of two lines created above and named as tool axis facing x direction

• Create a intersection on zy plane for the given surface

• Create a point to point line as shown below

• Add bisecting line as shown below by the reference of two lines created above and named as tool axis facing y direction

• Now create a tooling axis by the reference of tool axis facing x direction and tool axis facing y direction

PERFORMING DRAFT ANALYSIS

• To easily pickup the class a surface and tooling axis on tree, insert a publication on tools
• To perform draft analysis open customize view parameters and choose the material

• Insert a feature draft analysis by following these commands

insert>analysis>feature draft analysis

• Align the compass on tooling axis that we created
• Open the color scale and enter the value is 3 deg.
• If the whole body is green that all the faces is greater angle than the provided angle
