Abstract:

This diploma thesis describes realization and testing on-the-fly measurement using tracking interferometer. This measurement enables to achieve higher amount of measured points and decrease time of machine tool calibration. Calibration and verification values of machine parameters, as well as time of measurement and other details of this method are compared with results of conventional method called trigger. To evaluate the quality of volumetric compensation created from calibration values, we use verification measurement of circular interpolation.

Abstract:

This diploma thesis deals with the influence of electronic compensation on accuracy of the measurement using the touch probe. The theoretical part concerns touch probes, specifically their classification, principles of working and applications. This part also includes devices used later in the experiment, particularly double ballbar, laser interferometer and LaserTRACER. The Practical part describes an experiment, demonstrating the correlation between the accuracy improvement of the touch probe and the electronic compensation’s level. All measurements were executed in accordance with the norm

As Máquinas de Medir a Três Coordenadas (MM3Cs) desde sua criação evoluíram sensivelmente, entretanto poucas foram as modificações estruturais observadas. Hoje, para fabricantes de máquinas destacarem-se no mercado, são necessários grandes investimentos na busca de novos materiais estruturais e no desenvolvimento de programas computacionais cada vez mais versáteis. O sistema eletrônico e os programas computacionais utilizados durante as medições são inacessíveis e rígidos. Estes aplicativos normalmente não podem ser analisados nem modificados pelo usuário. São exemplos clássicos desta rigidez

Therefore, NTU Metrology Lab developed a Micro coordinate measuring machine (Micro-CMM) with high precision. This research presents the combination of industrial techniques, including an Abbe free XY Co-planar stage, Z-axis ram, scanning probe and high-resolution sensors. Based on these parts, the goal of this research is to improve Micro-CMM, which contains Laser wavelength error and volumetr

Abstract:

Machine tools produce positioning errors due to thermal and structural deformations of the structural elements, geometric errors due to inaccuracies in the manufacturing and assembly of their components, and computer numerical control errors caused by the bandwidth of their servo drives. This thesis presents the measurement, modeling and compensation of geometric errors of three axis machine tools in order to simulate and improve their volumetric accuracy in virtual environment. The geometric accuracy of each axis is measured using a laser interferometer. The displacement, pitch, yaw an

Abstract:

碩士<br>國立臺灣大學<br>機械工程學研究所<br>104<br>The position feedback control of NC machine tool controllers mostly employs displacement sensor (such as optical scale or encoder) as a single sensor system. Distance between axis of sensor and axis of cutting could lead to massive enlargement of the positioning error of each axis which is known as the Abbe principle. The movement of linear stage inherently has position and orientation errors in six degree of freedom, which are three linear errors (positioning error, horizontal straightness and vertical straightness) and three rotational angles (pitch, yaw

碩士<br>國立成功大學<br>機械工程學系<br>106<br>The purpose of this study is to improve the machining precision and processing efficiency in the milling process of thin workpieces. In the case of thin workpieces, elastic deformation is the main problem causing volumetric errors during milling. To solve this problem, the tool path is modified to compensate for volumetric error. First, the cutting forces generated during the milling process can be predicted from a cutting force model. Second, in order to analyze the elastic deformation of a workpiece, feature points are chosen on the workpiece, and the predict

On account of avoiding elastic deformation of thin workpieces caused by multi-axis machining, most engineers in the past must repeat test and measurement in the process planning stage for the optimal material removal within precision requirement. If an analysis and compensation system for volumetric errors of thin workpieces can be established, it will provide for user
