“…As shown, the problem of erroneous movements of machine tool spindles can be investigated in many different aspects, which may include searching for new technical solutions for research equipment, striving for ever higher accuracy of measurements, and creating new computational algorithms in control systems or detailed studies of the influence of selected factors on the final result measurement as well as the influence of erroneous movements on the quality of the treated surface [46]. At the end of this section, it is worth mentioning the works devoted to the influence of geometrical errors in rolling bearings [47] and hydrostatic bearings [48] on the values of erroneous movements.…”

The spindle of a machine tool is an important component of the machine. Its condition affects not only operation of the machine tool but also, above all, the quality of the workpiece. This paper explains the terminology and describes the research methods used to measure the spindle error movements of cutting machine tools. This article explains the impact of spindle motion inaccuracies on the quality of workpieces, quotes the requirements of European and American standards, and describes the current state and directions of development of the presented methods. Our own research work in this field is also presented.

“…However, the machined surface is the result of many factors and the surface form cannot fully reflect the spindle error motions. Ma et al [26] applied three-point error separation method in hydrostatic spindle error measurement, which features online finish turning. Shu et al [27] studied the measuring uncertainties resulting from sensor alignment and non-linearity for Donaldson reversal and three-point techniques.…”

This paper presents a complementary multi-probe method for measurement of radial and tilt error motions of a spindle. Neither indexing of artefact nor rotating of spindle housing is required and thus make it suitable for in situ evaluation of spindle performance effectively. In order to minimize the harmonic suppression problems commonly encountered in the multi-probe measurement approach, three sets of probe angle combinations were optimized and the harmonics of the three measurements were extracted and composed to reveal the true artefact errors in a complementary way. The exact probe angles were identified by the correlation function of the probe signals after the sensors are mounted onto the fixture and the requirement of high-precision fixtures was alleviated. The evaluation of measurement results showed that the erroneous harmonics were greatly reduced by 70%. Using this method, the radial error motions of the precision air bearing spindle were measured at seven axial positions and then the synchronized tilts error motions were calculated. This demonstrated an effective approach for measuring four degree-of-freedom error motions in one setup with a small number of displacement sensor probes.

“…The associate editor coordinating the review of this manuscript and approving it for publication was Qiang Miao . method of quantifying radial rotating error, it only indicates the rotating performance in non-rotating conditions [6]. Since the radial motions of spindle vary significantly with different rotation speeds, as described in [2] and [7], the speeddependent evaluation for rotating spindles has been widely recognized as a popular evaluation method [8].…”

Load-Dependent Rotating Performance of Motorized Spindles: Measurement and Evaluation Using Multi-Zones Error Map

et al. 2019

The rotating performance of motorized spindles is critical to the dimensional accuracy and surface quality of the parts to be machined. This paper proposes a novel measurement strategy and an evaluation method of spindle's rotating performance, considering the loads imposed on the spindle. To be specific, cutting loads are simplified as a unified function to guide the load simulation, and the load-induced error is eliminated using a position adjustment procedure. In a certain speed-load combination, the spindle's rotating performance under the unified load function is measured using a data envelope method. To extend the assessment to all typical work conditions, an evaluation scheme for different speed and load combinations is proposed based on a visual ideal of Multi-Zones Error Map (MZE Map). The necessity of considering the load-dependent rotating performance is demonstrated via several tests conducted on proposed load simulation platform. Besides, the procedures for developing the MZE Map are performed, and the results express an overview relationship between rotating performance and different speed-load conditions. The proposed method provides a new approach to evaluate the rotating performance considering the actual load conditions. This load-dependent oriented evaluating strategy contributes to a more precise health evaluation and management method for motorized spindles in actual machining process.INDEX TERMS Rotating machines, load modeling, performance evaluation, prognostics and health management.
