Week 11 - Final project
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 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
INPUT OF CLASS A SURFACE
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
- 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
- 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
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
- Create a point and insert a axis system on the point 1 as shown below
- Create a point to point line as shown below
- Create a intersection on ZY plane for the given surface
CREATION OF SIDE TOOLING AXIS Y
- Create a point on surface and create a line using point direction, use direction as y axis.
- Drag a compass and place it on axis that we created. Adjust the compass till we get correct view. lock the orientation of the compass.
- Modify the above line by changing the direction along compass
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
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
Map poket Class B :
BOTTLE HOLDER CLASS B :
LOWER SUBSTRATE CLASS B
ARMREST 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 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
LOWER SUBSTRATE CLASS C SURFACE
BOTTLE HOLDER CLASS C SURFACE
ARMREST CLASS C SURFACE
CREATION OF B SIDE ATTACHMENT FEATURES
DOG HOUSE
- Extract the surface that we going to create a dog house
- Insert a axis system. use positioned and draw a dog house sketch
- Sweep the sketch to 1.5 degree on the direction of main tooling axis
- Add thickness to the above sketch of 2.5mm by using thicken surface
- Trim the portion to get the required sketch
- Draft to 5 degree along second tooling axis
- Add fillet to all faces
- Assemble the doghouse to lower substrate solid
- Translate the doghouse to wherever we need
- To place pushpin on the doghouse create a ribs to doghouse
- Trim the ribs with doghouse
PUSHPIN
- Draw a sketch of pushpin by using positioned sketch command
- Ensure that the sketch is iso constrained
- Shaft the sketch to 360 degree by using shaft command
- Add minimum fillets to pushpin
HEAT STAKES
Heatstakes is known as thermoplastic staking is the process of joining two dissimilar metals together
- Extract the surface that we going to create heat stake
- Use positiioned sketch and draw a heat stakes sketch
- Use pad commands for the sketch to till we required
- Draft the stakes minimum of 0.5 degree
- Add fillet 0.5mm o all faces
- Assemble the heat stake to lower subtrate solid
- Maintain a 50mm minimum between two heat stakes
- Translate the heatstakes to wherever we need
- Trim the all heat stakes with lowersubstrate solid
LOCATOR
- Extract the surface that we going to create locator
- Use positiioned sketch and draw a locator sketch
FLANGE
Create a flange for attachment of heatstakes and locators at lower substrate
