Background The Magnum Shear™ cuts flooring material in a “dustless” manner. It is lightweight and requires no electrical input.

Introduction Objective: Motivation: Create a test apparatus to measure load versus blade position Improve the quality of a cut edge produced by the Magnum Shear™ Motivation: Expand target client base Improve understanding of cutting mechanics

Force Analysis Apparatus Force as a function of position Test prototype blades Test various materials Re-locatable to Bullet Tools

Lessons Learned Strain gages are not viable Recommendations I-beam is too stiff Recommendations Customized load cell SATEC or similar device

Composite Decking Blade Reduce the blow out by 50%

Crack Formation

Double Blade: Origin Discovered by conserving test material Thin slices change crack propagation

Double Blade: Cut Sample Stock Magnum Shear™ Double Blade Cut

Double Blade: Pros and Cons Reduces blowout by over 50% Easily installed on stock Magnum Shear™ Cons Greater force required for cut Material between blades is wasted

Future Improvements Lower Operator Force Discard Material Longer Lead/More Clearance Longer Handle Thinner Blades Discard Material Easily ejected Simple Add-On
