Instron Die Set Testing, Membrane Cutting, and Report
This project originated from observed issues on the manufacturing line at MilliporeSigma’s Cork, Ireland facility, where variations in membrane cutting performance were affecting product consistency. To address this, I designed and built a custom fixture for the Instron testing machine to measure the force required to cut membranes using different punches and dies. The goal was to quantify drag forces, identify optimal tolerances, and establish a standardized cutting process. I modeled the parts and assemblies in SolidWorks, created detailed machining drawings, selected and procured hardware, and assembled the final test setup. I then conducted testing, analyzed the data, and compiled a comprehensive report outlining findings and recommendations for process improvement.
I first started by getting an off-the shelf die set, made modifications to it in CAD, and created other necessary fixture parts, drafted detailed drawings for off-site machine shop.
