01 // ISOMETRIC 3D CAD RENDER

01 // TECHNICAL CHALLENGE

External hydraulic hoses were vulnerable to flying CNC aluminum chips, causing fluid leaks and fixture reload downtime every few days.

02 // ENGINEERING & DFM SOLUTION

Engineered gun-drilled gunmetal internal fluid passages inside a heat-treated 4140 steel manifold block, incorporating quad-ring seals and micro-inductive sensors.

03 // MODELING & TOLERANCING HIGHLIGHTS

—Complex gun-drilling clearance verification using SolidWorks Intersect tool

—3D Model-Based Definition (MBD) step files with native Y14.41 annotations

—Dynamic motion assembly simulation with hydraulic fluid velocity checks
