Prove a Six-Axis Robot on Your Own Workpiece
For an assembly robot, the decisive demonstration is running the buyer's actual industrial workpiece through the intended cycle. Use the catalog values as reference points, not guarantees for a supplied model.
Before signing off on a six-axis assembly robot, require the demonstration to use your own industrial workpiece, not a supplier sample. A robot rated to a 25 kg maximum payload and 1,831 mm reach may handle your part on paper, but the real question is whether it can present that part to the fixture within your tolerance. Ask the supplier to run the actual workpiece through the intended assembly cycle and record cycle time, approach paths, and any near-collisions.
In the request for quotation, specify the workpiece mass, center-of-gravity offset, gripper mass, and required orientation at the fixture. Compare the quoted payload and reach against those combined figures rather than the robot alone. Treat the ±0.02 mm repeatability figure as a catalog reference value; confirm how it was measured and whether it holds with your tooling fitted. In the acceptance test, define pass criteria: repeated placement of your workpiece, no interference with fixtures, and documented results at the working envelope edges.
Before requesting a quote, confirm with the supplier which workpiece and tooling will be used in the demonstration, how repeatability will be measured with that setup, and what documentation of the trial you will receive.
