Pass/Fail Checks for a Six-Axis Robot Factory Acceptance Test
Buyers should define measurable acceptance checks for an assembly robot, using catalog values such as 25 kg payload, 1,831 mm reach and ±0.02 mm repeatability as reference points, not guarantees for a supplied unit.
For an assembly robot, decide before the factory acceptance test whether pass or fail will be judged on a defined test path at a stated payload, or on a broader demonstration of the full working envelope. That choice shapes the checklist you attach to the purchase order.
Ask the supplier to propose a test path that exercises the six axes and the assembly motions you actually need. Will the test be run at the catalog reference payload of 25 kg, or at your expected load? Will positions be checked near the 1,831 mm reach limit as well as close to the base? How many cycles, and how many repeated approaches to each position, count as sufficient evidence?
Treat the ±0.02 mm repeatability figure as a catalog reference value. Confirm how the supplier measures repeatability, with what instrument, and whether the result applies to the tested unit under agreed conditions. Agree in advance which deviations fail the test and whether a retest is allowed.
Before requesting a quote, confirm with the supplier the proposed test procedure, the measurement method, the payload and positions used, the pass thresholds, and what documentation will be provided as acceptance evidence.
