“…The component error functions can be acquired from the repetitively measured data by considering the statistical distribution of the residual errors [15]. Fig.5 shows an example of extracting the repeatable error function from the repetitively measured straightness error data on a high precision machine.…”

Numerical error compensation is a cost-effective way to further improve the accuracy of high precision CNC machine tools. This paper discusses the major techniques for numerical error compensation on high precision machine tools. First, the high accuracy 2D holographic scale system and the dedicated measurement software are introduced. Then, the mathematical modeling of repeatable machine tool errors and the synthesis of volumetric error model are presented, followed by a description on the procedure of NC code modification. Error compensation experiments have been performed on a ballscrew driven machine tool and a linear driven machine tool. The experimental results show that numerical error compensation is generally effective on machine tools with both drive systems, while the linear driver system provides better dynamic performance for further improvement when the control precision is increased.

“…However, with one setup, the laser interferometer system can only measure one error element, and the optic setup and laser-path alignment is time consuming before every measurement task. Thus, some developed methods and measuring systems have worked to measure multiple geometric errors simultaneously to speed up the calibration [1][2][3][4][5][6]. Most of them need a complex optical setup.…”

A simple measurement system has been developed and implemented for the simultaneous measurement of pitch, yaw and roll of the moving axes of a linear stage. This developed system is based on the principle of the diffractive theorem and optical triangulation. It is composed of a laser source, two quadrant detectors and a diffracting grating. The diffraction grating mounted on the moving axes of a stage reflects an incident laser beam into several diffractive rays and two quadrant detectors are set up for detecting the position of ±1st-order diffraction rays. When the diffraction grating moves, the locations where the diffractive beams are generated change and also the positions of the spots on two quadrant detectors. According to the relationship between the three angular motions of a moving stage and the output coordinates of two quadrant detectors, an inverse algorithm is used to solve these pitch, yaw and roll angular errors through a kinematic analysis.

“…Therefore, investigation has been carried by Ren et al [11] CMM. In fact, an online error compensation system based on three laser optical multi-degree-of-freedom measurement systems (MDFM systems) for CMMs has been presented by Huang and Ni [13]. This system provided flexibility to measure error components by using both on-line and off-line measurement methods.…”

Abstract. There have been substantial improvements in measurement systems in order to meet fluctuating market demands. This rapid change and development in measurement technology has primarily been governed by demands of accuracy and precision from aerospace, automotive and other manufacturing industries. Coordinate measuring machines (CMMs) available with different technologies and configurations has efficiently been fulfilling customer demands for more than a decade. Though, current CMMs can meet needs of rapid and increased demands of customers to a greater extent but still there is lot of scope for improvement and development in CMMs. The globalization of manufacturing has resulted in development of variety of complex products and miniaturization of mechanical components. The technology of micro/nanoscale 3D measurement is still a bottleneck for industries. Therefore, precise and accurate system which is flexible enough to deal with complexities of parts and micro & nano range products has to be investigated. In this paper, comprehensive review concerning CMMs with capabilities to measure micro/nano features has been presented. This work has also discussed different methods to estimate measurement uncertainty, as well as performance evaluation of CMMs. Moreover, novel concepts such as intelligent CMM, multi-sensor CMM, virtual CMM have been presented.
