Week 11 - Project - A pillar Design with Master Section

AIM :-

To create a pillar Design with the help of Master Section, that is provided with the Cat file in the Classs A surface.

ABSTRACT :-

For the creation a pillar Design with the help of Master Section, that is provided with the Cat file in the Classs A surface, we need to maintained a proper features in mind that is neccesary to complete this work.

• Points to ensure:

1. In Tree StructureEnsure using the surface command.
2. Use closed body command to create the solids
3. Rename the geometrical set properly.

• Output Required in a ppt :-

1. Picture of the sketches with Sketch solving status’s geometry tab
2. Picture of the Detailed tree structure.
3. Picture of the 3D CAD
4. Create closed body
5. Create a tooling axis and follow design rules.
6. Follow the Master section to create a flange
7. Follow the master section for thickness and to create the Closed volume.
8. Follow the master section to create Attachment features
9. The thickness of the Plastic to be 2.5 mm

SOLUTION :-

Master Section :-

• Master Sections are the guides for design requirements which shapes the component after technical styling of Class A Surfaces.
• Master sections are the guides for design requirements that decide the component packaging after technical (Styling, Concept, or Class-A) surfaces. Creating this master section should need 5 to 6 years of experience.
• This helps you to decide the feasibility, clearance, packaging, and fixation strategy before working it on a 3D. We have a master section.

SNAP_3 :- Class A with Master sections

PROCEDURE_1 :- Creation of Tooling Axis

Tooling Axis :- In injection molding, the Class A surface is first analyzed to determine the axis or tooling direction that separates the molds. Tooling direction is critical for plastic product design because it determines mold direction. It is a main axis towards the direction the component ejject with also an core & cavity open or close.

The tooling axis created here with the reference of a master sections.

• First we need to create a point, point defination as a between.
• The point created between the 2 line point selected from the master section.
• After the point creation extract the 2 lines which are from the 1st master section. & hide the same master section as well for the better crearance view.
• Then this 2 lines has extraced used as a referance line for the creation the 1st Bisecting line.
• The same procedure are used for creation the another 2nd line from the 2nd master section repectively.
• Here we got a 2 Bisecting line in which we need to create a common line that is bisecting method again 7 finally we get a main Tooling axis.

SNAP_4 :- Tooling Axis Created Yellow line as shown.

PROCEDURE_2 :- Creation of the Class B surface.

For creation the Class B surface we need to offset the Class A surface to the downward direction with the 2.5 mm .

SNAP_7 :- Offset of class A

After offseting we got a uncleared surface the large cut/ patched surfaces has got.

SNAP_8 :- Class B Patch area

so for the filling this patch / uncreared area we need to select a boundary with the adjecent corner of a offseted are & apply a sweep there.

SNAP_9 :- Clear class B by applying sweep.

After that we need to select a join commond & select a offset & sweep together for getting a better class B surface.

SNAP_10 :- Modified Class B

PROCEDURE_3 :- Creation of Class C surface

For the creation of Class C surface we need to take a multiple sweeps all over boundary line of the Class A

SNAP_11 :- Creation of Class C surface applying multiple sweep.

1. In this procedure we need the Class A again to as a referance for creation the Class_C surface.
2. Here 2 types of Sweeps are used for the making class_C surfaces.
3. The 2 types as 1st is taking a referance surface with an angle of 90 Degree &
4. 2nd is with the draft direction with the angle of 3 Degree. In the referance with surfaces we take a referance as a Class_A & in the with the draft direction as a Tooling axis as well.

SNAP_12 :- Multiple sweeps of cass C surface

After the sweeps are applied there is need to trim the adjecent matting surfaces, so we need to extrapolate the proper extreme boundary line and apply the trim & finally join the trims together with an merging distance 0.003mm as well.

SNAP_13 :- Complete Class C surface

PROCEDURE_4 :- Final trim / Closed surface.

when we move on for getting the closed surface here we need to take a trim between the Class A + Class C or also we can join as well. After getting this trim we need to trim the Class B surface with the Class A+B . In this way we got a closed surface.

SNAP_14 :- Triming Class A with Class C

SNAP_15 :- Trimmed class A+C surface with Class B surface

SNAP_16 :- Complete Closed surface

PROCEDURE_5 :- Closed Solid Body/ Final component.

After getting a closed surface, we need to insert a new body in the tree structure. First Switch the workbench into part design & select a command closed surface to make a solid body.

SNAP_17 :- Closed Body component

SNAP_18 :- Draft Analysis of a closed body component.

PROCEDURE_6 :- B_side feature creation.

1] Dog house creation

We always create a B side feature or a attachement by using the help of master section & make a sketch properly guidence with the master section. First create a mid-point between the 2 point of a 2 lines of a master section followed by the dog house section. Finally created a iso-constrained sketch as well.

SNAP_19 :- Sketch of a Dog-House

2] PLATE :- In the same way the plate has created

SNAP_20 :- Sketch of a plate

3] RIBS :- same way the Ribs also created with the help of master section.

SNAP_21 :- Sketch of a Rib

4] Pocket :- The pocket has created at the top face of a dog-house with proper iso constrained.

SNAP_22 :- Sketch of a Pocket

1. After the sketches has make we need to pad or extrude it with proper thickeness has to be provided.
2. In this way we have need to create the B-side feature dog-house inside sub elements of a Dog house as Plate,Ribs & pocket.
3. The draft angle also has provided to inside the dog house is 0.5 with the referance of Tooling Axis & for the ribs & plate is 0.5 by the side core axis or lifter.

• Draft Angle Provided to the B side features & complete closed component.

SNAP_24 :- B] Draft Analysis to the complete closed component.

• TREE STRUCTURE.

• FINAL COMPONENT WITH ALL VIEWS :

CONCLUSION :-

In this way we have cteated the closed body by the provided Class A surface. After this we have Created the B-side feature with the help of master sections as well. The required snaps are attached to the report & Explained each steps respectively. Finally Cat part file is also browse.

Thank You.
