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

OBJECTIVES:

• Create a sketch by using a Positioned sketch
• All the should be sketching should be 'so-Constrained
• Ensured Proper Tree Structure
• Geometrical sets should have 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

INPUT OF CLASS A SURFACE:

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 surfaces have been assembled together in one cat product.

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.
• create a point -direction line parallel to the y axis and named as TOOLING AXIS as shown below.

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,we have to create tooling axis on Y

CREATING THE TOOLING AXIS

• Create a point 1 and insert a axis system on the point 1 as shown below.
• Create a intersection on XY plane for the given surface.

ARMREST

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, there is an chance for undercut when we consider tooling axis from z.so we have to create tooling axis on x,y and also z.

• 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.
• create a point -direction line parallel to the y axis and named as TOOLING AXIS 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

• Analyse the class A once where the sweep is easier to create towards tooling direction
• Create a boundary using limitation points whereever possible for sweep 
• Sweep the above boundaries for industrial standard 3 degree towrads tooling axis
• Now Create the c surface by using multisection solid where the sweep cant perform.
• Create a points on the curve as shown below and Create a line by using point to point line
• Split the both surfaces by using split command
• Create a boundary by using on the class a surface that is going to pefrom multisection surface
• Join the surfaces by using multisection surface
• By using the same method creating the c surface whereever the sweep is not possible
• After ,join all the c surface
• Using the same method create c surfaces for all the parts
