CMM Demonstrations: Test With Your Own Workpieces
A buyer's guide to requiring a coordinate measuring machine demonstration on the buyer's actual industrial workpieces, with practical checks tied to measuring travel, resolution, and maximum workpiece mass.
Ask the supplier to demonstrate the coordinate measuring machine on your own industrial workpieces, not on a polished sample. Before agreeing, decide which parts represent your range: the largest, the heaviest, and the most feature-dense. A demonstration on your material shows how fixturing, probing, and reporting behave under your conditions.
Compare candidates by asking each supplier to run the same parts and return the same inspection report. Check that each workpiece fits the stated measuring travel of 500 × 700 × 400 mm and stays within the stated maximum workpiece mass of 180 kg; treat these catalog values as reference points and confirm they apply to the offered configuration. Ask how the stated resolution of 0.0001 mm is achieved and displayed, and whether it is meaningful for your tolerances. During the demonstration, watch setup time, probe access to critical features, and how the software reports out-of-tolerance results.
Before requesting a quote, confirm with the supplier which workpieces will be used in the demonstration, who supplies fixtures, how results will be documented, and whether the demonstrated configuration matches the quoted machine.
