V-Mill Demonstration

For the testing of composites, few samples are harder to make than the shear test specimen, whether for the ASTM D5379 V-Notched Beam Method sample, or the ASTM D7078 V-Notched Rail Method sample.  In response to demand for an easier way to notch these blanks, Tensilkut Engineering developed the V-Mill I, which employs a custom diamond coated wheel to accurately complete the notch without tool marks or deformation, while maintaining the tight tolerances, including depths and angles, required for a successful test.

This is a video demonstration, which first explains the principles behind the machine, followed by the actual notching of a carbon fiber specimen.

The specimen finished during this demonstration, along with two others made from different materials, are shown here.
