Before the test
Prepare material name, grade, dimensions, drawing, cut path, target kerf, tolerance, surface requirement, coolant limitations, and expected production volume.
Define what success means before cutting. Success may be speed, low chipping, low kerf, acceptable roughness, or simply proof that the material can be separated.
During and after the test
Record wire speed, feed rate, tension, coolant, wire diameter, loop length, cut time, wire condition, and visible defects.
After the test, inspect surface roughness, cracks, edge quality, kerf width, and whether the process is repeatable.
