Flash Flatness Measurement System Using Digital Dial Gauges

Batch or mass production of workpiece has raised new challenges for high-efficiency measurement, especially the measurement of flatness, which is a key parameter of machining tolerance. This paper presents a novel flatness test system utilizing array of digital micrometer gauges. The software is developed based on .NET. Experiments on oil coolers are carried out with 20 sampling points, comparison with coordinate measuring machines and the steadiness of both the single gauge and the system is presented, and the results show that the system achieves high measuring speed and high consistency.
