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 the Positioned sketch
• All the should be sketches should be Iso-Constrained
• Ensured Proper Tree Structure
• Geometrical sets should have a proper name based on the sketches present inside of it
• Create thickened part using the master section for reference
• Create the mounting features as per design guidelines in the industry and with master sections
• Creating Draft analysis & Tooling analysis
• Creation of parting lines and checking 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 a separate part. Also performing draft analysis and tooling axis separately. finally, all the surfaces have assembled together into one catproduct

CREATION OF TOOLING AXIS – LOWER SUBSTRATE

DRAFT ANALYSIS

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 a minimum draft angle is 3 degrees

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 the draft.

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

CREATING THE TOOLING AXIS

• Create a point on the center of gravity of part by using the measure inertia command and insert an 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 TOOLING AXIS – BOTTLE HOLDER

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

• 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 TOOLING FACING X DRIECTION

• 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 TOOLING FACING Y DRIECTION

• Add bisecting line by the reference of tooling facing x direction and tooling facing y direction and named as tooling axis

CREATION OF TOOLING AXIS – 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

CREATING THE TOOLING AXIS

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

• 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 TOOLING FACING X DRIECTION

• 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 TOOLING FACING Y DRIECTION

• Add bisecting line by the reference of tooling facing x direction and tooling facing y direction and named as tooling axis

CREATION OF TOOLING AXIS – UPPER SUBSTRATE

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

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

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

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

LOWER SUBSTRATE CLASS B

BOTTLE HOLDER CLASS B

ARMREST CLASS B

UPPER SUBSTRATE CLASS B

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 comman.
• 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

LOWER SUBSTRATE CLASS C SURFACE

CREATION OF B-SIDE ATTACHMENT FEATURES

using the master section to create the Flange, Locater and Heat Satke position in all component
