I designed and modeled a semi-automated, precision Advanced Gem Pre-Forming Machine aimed at optimizing gemstone calibration, reducing material wastage, and improving dimensional accuracy.
Key Engineering & Design Contributions:
3D CAD Modeling & Assembly: Created a complete, detailed 3D assembly in SolidWorks, incorporating a custom headbox, precision centering mechanisms, radius change systems, and a transparent safety guard.
Power Transmission Design: Engineered and selected components for the mechanical drive systems, including gear motors, timing belts, jaw couplings, and lead screws for precise linear motion.
Mechanical & Structural Analysis: Conducted Finite Element Analysis (FEA) to evaluate stress, displacement, and structural integrity on critical components like the drive shafts, machine headbox, and safety guards.
System Integration: Integrated technical specifications for variable frequency drives (VFD), dial gauges for micro-adjustments, and a customized water circulation and filtration system.
This project demonstrates my ability to take a complex mechanical problem from conceptual design through detailed engineering calculations, component selection, and final 3D CAD realization.

I designed and modeled this custom external gear hydraulic pump specifically to power the lifting mechanism of a two-wheel agricultural tractor trailer, enabling efficient loading and unloading.
Because standard off-the-shelf pumps often do not match the specific RPM, space constraints, or power output of small two-wheel tractors, this pump was custom-engineered from the ground up.
Key aspects of this project include:
Complete 3D CAD Assembly: Created a highly detailed 3D model in SolidWorks, ensuring all components fit together with strict manufacturing tolerances.
Component Design: Modeled the complete internal architecture, including the main casing, drive and driven gears, precision bearing blocks, and heavy-duty structural assembly bolts.
Sealing & Fluid Dynamics: Carefully designed the internal routing and integrated O-ring grooves to ensure high-pressure fluid containment without leaks during heavy lifting operations.
Exploded Views: Generated professional exploded assembly views to clearly demonstrate the internal mechanics and aid in the manufacturing and assembly process.
