Week 8:- 3D Finishing Challenge 2

Week 8 Challenge: 3D finishing

Aim:

• Perform 3D finish for all units of assembly design
• Create rough locators for assembly.

3D FINISH:

The 3D finish is the process where design is completely finished and ready for final simulation and 2D detailing. In 3D finishing we perform and ensure the following points:

Hole concentricity and hole sizes- All parts hole concentricity is checked while finishing the parts.

Machining area- The machining area in every part is defined and the machining area is highlighted by using orange color.

Nominally: All units dimensions are maintained nominal to facilitate easy assembly of the unit.

Holes coloring standard- Color code standard used in 3D finishing.

• Cyan-Simple hole
• Yellow- Threaded hole
• Orange-Machined area
• Blue-Dowel hole.

Fasteners implementation- Fasteners are implemented in all units as per the requirement and load on the part.

Avoiding clash between different parts- Proper gap is maintained between parts to avoid the clash.

Mylar splitting as per panel profile- Mylar splitting is confirmed while finishing the design.

Proper renaming of parts/assemblies as per standard-Proper renaming of parts and assemblies are done while finishing the design hence we can identify each and every part easily with a unique identification.

• Renaming and structuring of the design tree:

Renaming of the design tree is done and structuring the design tree in a way that it's simple to identify the units. Some units are used multiple times and those are easy to identify by their name.

Base unit:

• Renaming of parts and structuring design tree.
• Threaded hole and dowel holes making nominal and color-coding are done so it is easy to distinguish holes.
• Threaded hole(yellow), clearance hole(Sky blue), Dowel hole(Blue), Machining surface(orange).

Retractable Pin unit:

• Holes are made nominal and concentric to each other.
• The open position of the retractable pin is shown in yellow color.
• The proper butting of the two parts is done.
• Color coding is done as per the standards.
• Structuring design tree renaming of the parts is done.
• Below are some images after 3D finishing is done on the fixed pin unit.

4. Swivel clamp unit:

• Holes are made nominal and concentric to each other.
• The proper butting of the two parts is done.
• Fasteners are implemented.
• Color coding is done as per the standards.
• Structuring design tree renaming of parts is done.
• Mylar splitting is done.
• The open position is shown in yellow color.
• Below are some images after 3D finishing is done on the swivel clamp unit.

5. Power clamp unit:

• Holes are made nominal and concentric to each other.
• The proper butting of the two parts is done.
• Fasteners are implemented.
• Color coding is done as per the standards.
• Structuring design tree renaming of parts is done.
• Mylar splitting is done
• The open position is shown in Yellow color.
• Below are some images after 3D finishing is done on the swivel clamp unit.

8. Rough locator:

• Provide a locator in 4 directions.
• Mention 0 mm gap between rough locator and panel.
• Here I used 6 rough locators as shown below.
