1/5/2018, · To solve this problem, in this paper we take the SCK230 ,drill pipe, thread-repairing machine tool as a carrier to design and achieve a fast and on-machine measuring system based on a laser probe. This system drives a laser displacement sensor to acquire the contour data of a certain axial section of the thread by using the servo function of a CNC machine tool.

The relative standard deviation (,RSD,) for detection of 10 μM and 50 μM of UDMH were 3.1% and 1.6% (n = 6), respectively. The proposed method exhibited convenience, anti-interference, stability and reproducibility abilities, making it possible to successfully detect UDMH in tap and lake water samples.
