Week 9 - Attachment Feature Creation - Challenge 2

OBJECTIVE

Converting the given CLASS A surface into closed body and make 2 Dog house on body and perform draft analysis

PROCEDURE

Given step file is convert into CAT and given bumper model taken as CLASS A SURFACE

CLASS A SURFACE

Check for gaps between surfaces for that click on join and then preview. If theres any gap between the surfaces join them with a maximum tolerance of 0.003 mm.

TOOLING AXIS

Normal tooling axis does not working here

Create point on the body

using normal to body option make a line and make it as TOLLING AXIS

DRAFT ANALYSIS

The Draft Analysis command enables you to detect if the part you drafted will be easily removed. This type of analysis is performed based on color ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.

• The draft analysis is done by clicking feature drafat analysis or go to TOOLS>ANALYSIS>DRAFT ANALYSIS
• on the bar select the compass and place it on the tooling axis and lock the compass and click on the body
• As u can see the body comes in GREEN in colour that ie angles are under 3 degree and ready to draft

CLASS B CREATION

we can easily off set the CLASS A by 2.5 mm and create class B surface

Work on the patch and make body same as class A

CLASS C CREATION

• Extract the boundary from the class A surface using boundary command.
• Use sweep command > choose profile type line > subtype as with draft direction > choose guide curve and draft direction > draft angle as 3 degree > preview.

• After class C creation Join Class A and Class C and trim it between class B to get Final body

• By moving to part body and using closed surface tool make a part body

• Final draft analysis

DOG HOUSE

• Make a square using sketch on the surface
• Pad it in 20mm
• Give draft of 1.5 mm
• Give fillet
• Using shell option shell it in 2mm
• For inside wall ectract base surface and wall
• offet wall in 1 mm (2.5*40%=1mm)
• offest base in 5mm
• trim them by dog house body
• give draft as .5 degree inside

Draft analysis out side of body

Draft analysis in side of body

PUBLICATION

CONCLUSION:

• The Tooling axis and the SolidCAT part with B Side Features is created from the given Class A Surface and Draft Analysis is Performed
