3D vision systems are more and more required in a large variety of applications and mostly for mechanical and medical purposes. This paper presents the study and realization of a prototype of a structured light automated tilt-rotational 3D vision system for high-quality reconstructions of components of various sizes and in cases of freeform and complex surfaces. The main goal of this research work was to develop an instrument with the following main novelties: configurability for different object sizes, high precision and resolution levels and ability to automatically generate the mesh representing the full scanned objects without any intervention of the operator by means of a 2 degrees of freedom automated tilt-rotational mechanical positioning system. A detailed analysis of the instrument and the procedures and results of the performance tests are presented, together with the examination of possible strategies to obtain a better performance, especially by the calibration and the synchronization between the optical and the mechanical systems. As a result, the prototype and the performance parameters resulting from the experimental campaigns, are reported.

“…Literature reviews show that some researchers have investigated the effects of the driven mechanisms 1 and the tool-setting techniques 2,3 on the performance of the rotary table as well as calibrating technique. 4 The published contributions on the rotary table techniques are numerous; however, so far there is no study on the support system that greatly affects the static and dynamic performance of the rotary table.…”

The rotary table of the heavy machine tools demands higher stiffness to provide substantial load capacity as well as a lower cost. The hydrostatic rotary table supplied with constant flow rate pump is not often used due to its high cost; meanwhile, the system with constant pressure pump suffers from a relatively lower stiffness problem. In this study, an alternative type of rotary table supplied by a constant flow pump and a constant pressure one is proposed to satisfy the requirements. The mathematical model is presented on the basis of hydrostatic theory to predict the axial static performance of the table. A comparison of the performances between constant pressure supply table, constant flow supply table and constant flow and constant pressure supply table has been conducted; the results show that constant flow and constant pressure supply table is the best in static behavior. A multicriteria optimization technique based on the weighted ideal point method is better than the single criteria optimization in achieving the comprehensive property of the table. A variation rate method is used to calculate the weighted factors. The optimization problem is formulated with the maximum stiffness, the minimum power dissipation and the minimum supply pressure.

“…Fan et al [12] developed a six degrees of freedom (6-DOF) measuring system by using four laser Doppler scales, two L-shaped plane mirrors, one long right-angle mirror, and two QDs for the measurement of six motion errors of a wafer stage. Jywe et al [13] proposed a simple and low-cost technique using a laser diode, a one dimensional (1-D) grating, two PSDs, and a reference rotary table with good repeatability to measure the four degrees of freedom (4-DOF) errors of a rotary table for a 360 • full circle.…”

Geometric errors, such as straightness, perpendicularity, and parallelism errors are determinant factors of both the accuracy and service life of a linear guideway. In this study, a multipurpose geometric error measurement system was mainly composed of a laser source and an in-lab-developed optical module is proposed. Two adjustment methods were used for the in-lab-developed optical module to calibrate the altitude angle of the pentaprism: The first one is designed for ease of operation based on Michelson principle using a laser interferometer as the light receiver, and the second is aimed at high calibration repeatability based on the autocollimator principle using the quadrant detector (QD) to replace the light receiver. The result shows that the residual errors of the horizontal straightness and the vertical straightness are within ±1.3 µm and ±5.3 µm, respectively, when referred to as the commercial laser interferometer. Additionally, the residual errors of perpendicularity and parallelism are within ±1.2 µm and ±0.1 µm, respectively, when referred to as the granite reference blocks
