In-process out-of-roundness measurement probe for turned workpieces

“…In the previous studies made until now [2, 3,4,5] it was highlighted the possibility to measure the work pieces processed on a lathe [2,3], especially on measuring the radial deviation of a shaft and to represent it into a virtual environment. The technical literature also presents some aspects concerning a study which presents the possibility to measure a work piece, using an optical sensor, from a milling machine [3] in order to measure the geometry of the processed part.…”

Abstract. Manufacturing Engineering domain generally uses for creating virtual work piece profiles or tool representations descriptive parameters or simplified drawings. More recent and accurate methods such as the present study uses optical devices for obtaining virtual projections of work pieces/tools. This paper presents an experimental method applied in order to obtain the profile for a given cutting tool, which can offer in addition possibility to estimate the cutting tool wear, without using such built-in machine-tool device. The experimental values obtained are materialized by the accuracy which characterizes the accurate profile of the measured cutting tool. This fact can make a difference between a classical measurement method applied outside of machine tool sector and a new one provided by a device which offers the solution to measure a work piece directly on the machine tool, without modifying the actual work piece orientation conditions and at a low price.

A LabVIEW based data acquisition system (LV-DAS) is developed for Electrical Impedance Tomography (EIT) for automatic current injection and boundary data collection. The developed LV-DAS consists of a NIUSB-6251 DAQ card, NISCB-68 connector module and an automatic electrode switching module (A-ESM). A LabVIEW based graphical user interface (LV-GUI) is develop to control the current injection and data acquisition by LV-DAS through A-ESM. Boundary data are collected for a number of practical phantoms and the boundary data profiles are studied to assess the LV-DAS. Results show that the high resolution NIDAQ card of the DAS improves its data acquisition performance with accurate measurement and high signal to noise ratio (SNR).
