ISSN: ISSN Online: 2768-7961 Beschreibung: <p>Producing large, high-quality workpieces requires precise axes with accurate guid ance systems, which results in a demand for tighter tolerances in the corresponding guide surfaces. However, these tight tolerances and rigid structural requirements in the surfaces lead to high manufacturing and assembly costs. This causes an in creased manufacturing and adjustment effort, especially for long linear axes, be cause the assembly cost scales with the axis size. A novel approach to circumvent these tight tolerance requirements lies in compensating for the errors in the guide surface by actively positioning the guide carriage. For this purpose, a double-sided actuator consisting of an electromagnet and an air caster is used. The advantage of such a system is the increased flexibility since it is not necessary to build a mechan ical wrap-around structure for the guide rail. The elimination of the wrap-around structure is advantageous because it also makes the parallel alignment obsolete. Ex isting bidirectional active guide systems are limited to micro-precision applications due to the air gap of aerostatic bearings in the single-digit micrometre range. An air caster decouples the air gap from the lifting height with an elastic bellows, resulting in a higher and broader operating range of the actuator. These properties enable the usage of the actuator in larger machine tools, for example, to manufacture wing frames for aircraft. Furthermore, the guiding system can be extended by adding fur ther guide segments at the end to extend the axis. This paper presents this new guid ing system by investigating the achievable forces and the stability towards disturb ance. The air caster is capable of a levitation force of up to 7,100 N with a levitation range from 250 to 280 µm, which makes ultra-precise surfaces unnecessary. The magnetic actuator provides attraction forces up to 2,300 N within this range. In duced disturbance forces of up to 250 N could be compensated by a PI controller with position errors below 1 µm.</p>

DOI: https://doi.org/10.20965/ijat.2026.p0057 Beschreibung: <p>Grinding is a process that still today largely depends on the skill and experience of the operator. For grinding, no generalized computer-aided manufacturing tool exists as for milling, and the grinding machine manufacturers have their proprietary process planning tools for the path planning. The success of a grinding process furthermore depends on a suitable conditioning of the grinding wheel and not only on the appropriate selection of the process parameters. Skilled operators are, on the one hand, capable of setting up the process in shorter time than their less skilled colleagues and with immediate success. Artificial intelligence, driven by sufficiently increased computational performance, is increasingly capable of handling manufacturing processes, particularly as these processes become more complicated and experience-based. Therefore, extending the machine’s ability towards what today is the task of the operator, namely process planning feeding the vision of “operator integrated” is a breakthrough in zero defect manufacturing and first part right for grinding processes. The paper conceptualizes an intelligent grinding machine that uses ontologies, applies rule-based planning tools, makes use of physical as well as autonomous modeling, and is capable of learning. Moreover, the processes of grinding and dressing are fully monitored so that a self-learning ability is provided. Learning is fed from different sources, from monitoring, from other machines requiring filters built on physical models, and from the operator with the ability to deal with incomplete, unstructured, and unreliable data. From this the way, how such a machine communicates with operators must be completely different than today. Research results and literature are provided to discuss the different aspects like machine state monitoring, process monitoring, and parameter selection for an optimized grinding process.</p>
