FAT Checks for a CNC Fabric Cutting Machine
A buyer's guide to defining practical pass or fail checks for factory acceptance testing of a CNC fabric cutting machine, with questions to raise in the RFQ and at the demonstration.
Before signing off a CNC fabric cutting machine, decide which cut samples will serve as the pass or fail reference. Ask the supplier to cut the same fabric and pattern at the low and high ends of the stated 1–60 m/min range, then compare edge quality, dimensional accuracy and repeatability against agreed tolerances.
Build the acceptance test around your own materials: woven and knitted fabrics, denim and selected nonwovens. Request a defined sample set for each, with the cutting speed and cut depth recorded for every run. Ask how many consecutive pieces must match before the test passes, and whether the machine must hold that result after a tool change or restart.
Confirm the site conditions the test assumes, including the 380 V AC, three-phase, 50 Hz supply. Clarify who supplies fabric, patterns and operator time, and whether the test runs at the supplier's facility or on site.
Before requesting a quote, confirm with the supplier which tests they will witness, what tolerances they will commit to in writing, how results are recorded, and what happens if a sample fails.
