Week 11 - Final project

AIM - To create a door interior part from the inputs of class A surface along with master section by following the design rules followed in tier 1 and OEM industries in catia v5

SOFTWARE USED

CATIA V5

OBJECTIVES

• Create a sketch by using Positioned sketch
• All the should be sketches should be Iso-Constrained
• Ensured Proper Tree Structure
• Geometrical sets should having a proper name based on the sketches present inside of it
• Create thickened part using master section for reference
• Create the mounting features as per design guidelines in the industry and with master sections
• Creating of Draft analysis & Tooling analysis
• Creation of parting lines and check tooling feasibility

Since the input class A surface is containing four different parts(class A). So class b and c for all the surface has been created in separate catpart. Also performing draft analysis and tooling axis separately. finally all the surface have assembled together in  one catproduct

CREATION OF TOOLING AXIS – LOWER SUBSTRATE

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 the above model the best tooling axis is y direction.

CREATING THE TOOLING AXIS

• Create a point on centre of gravity of part by using measure inertia command and insert a axis system on the point  as shown below

CREATION OF CLASS B SURFACE

• Insert a new gemeotrical set.Measure the value of thickness in master section.The value is 2.5mm
• Offset the class A surface to 2.5mm.
• Check all the sub elements are formed if not try to fix it locally

CREATION OF CLASS C SURFACE - 

CREATING CLOSED BODY - 

PERFORMING DRAFT ANALYSIS ON MODEL

• To perform draft analysis open customize view parameters and choose the material

• Insert a feature draft analysis by following these commands                                   

I         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

DRAFT ANALYSIS REPORT OF CLASS A – UPPER SUBSTRATE

WEIGHT OF THE COMPONENT

• Apply material plastic to the product
• Use measure command to caluacute the weight of product
•

CREATION OF PARTING LINE - 

Parting line is used to the differentiate between core and cavity

NOTE = THE PARTING LINE BELOW IS CREATED WITHOUT ATTACHMENT

CONCLUSION

Thus the door interior part has been created from the inputs of class A surface along with master section by following the design rules followed in tier 1 and OEM industries in catia v5
