The image below illustrates the machines used in the final project.

RC Production

🏗️

Define the design and dimensions of the RC furniture.

🏗️

Create a 2D/3D model of the furniture using CAD software.

🏗️

Export the design files to a format compatible with the ShopBot.

🏗️

Use CAM software to generate toolpaths, ensuring settings are optimized for plywood cutting.

🏗️

Choose high-quality plywood sheets suitable for furniture.

🏗️

Securely fix the plywood sheets onto the ShopBot bed.

🏗️

Load the toolpath files into the ShopBot controller software.

🏗️

Execute the cutting process, monitoring the ShopBot to ensure precision and safety.

🏗️

Sand the edges of the cut pieces to remove splinters and roughness.

🏗️

Assemble the pieces.

🏗️

Inspect the completed RC furniture for any defects or adjustments needed.

3D Printing Linear Mechanism:

🏗️

Define the requirements and constraints of your linear mechanism.

🏗️

Use CAD software such as Fusion 360 to create a detailed 3D model of the mechanism, including all components such as sliders, rails, and any mounting points for motors or sensors.

🏗️

Select appropriate filament materials based on the mechanical properties needed.

🏗️

Use slicing software to convert the 3D model into a format compatible with the 3D printer.

🏗️

Print the parts using a 3D printer

🏗️

Remove any supports and smooth out rough edges using tools like sandpaper, files, or chemical treatments.

🏗️

Assemble the printed parts.

🏗️

Conduct thorough testing to ensure the mechanism meets all design requirements and performs reliably under expected operating conditions.

Electronic Circuit and PCB Production:

🏗️

Create the schematic and design the PCB using KiCad.

🏗️

Mill the PCB and solder the components.

🏗️

Test the board and upload the program.

Logo For the ARC

🏗️

Define the design and dimensions of the logo.

🏗️

Use graphic design software to create the logo design.

🏗️

Export the design to a format compatible with the Trotec Speedy 400 (DXF).

🏗️

Import the file into Trotec JobControl software, adjusting the layout for optimal material usage.

🏗️

Choose an acrylic sheet of the appropriate thickness and color for your logo.

🏗️

Execute the cutting and engraving process, monitoring the laser to ensure precision and safety.

🏗️

Carefully remove any protective film from the acrylic pieces if present.

Final Project Schedule

🗓️

The Kanban chart of my final project is shown below

🗓️

The Gantt chart for my final project is shown below. After completing my final project, I prepared this Gantt chart. Due to the dengue fever, I lost 10 valuable days of my final project. I was unable to complete this task before the final project. However, I have prepared schedules and timelines in my notebook. Later, I digitalized it.
