“…It is not proposed to discuss differences in modern machines and applications in this paper, as it would require too much space for a single paper. However, a schematic of a special-purpose grinding machine is shown in Figure 3 as an example of innovative designs produced to achieve high productivity in the grinding of high precision mirrors and lenses [5]. Whereas most machines are based on an open "C" or "U" shaped structure for convenience of part-loading, a new generation of high precision machines employ a box structure to limit machine deflections.…”

Over the last century, substantial advances have been made, based on improved understanding of the requirements of grinding processes, machines, control systems, materials, abrasives, wheel preparation, coolants, lubricants, and coolant delivery. This paper reviews a selection of areas in which the application of scientific principles and engineering ingenuity has led to the development of new grinding processes, abrasives, tools, machines, and systems. Topics feature a selection of areas where relationships between scientific principles and new techniques are yielding improved productivity and better quality. These examples point towards further advances that can fruitfully be pursued. Applications in modern grinding technology range from high-precision kinematics for grinding very large lenses and reflectors through to medium size grinding machine processes and further down to grinding very small components used in micro electro-mechanical systems (MEMS) devices. The importance of material issues is emphasized for the range of conventional engineering steels, through to aerospace materials, ceramics, and composites. It is suggested that future advances in productivity will include the wider application of artificial intelligence and robotics to improve precision, process efficiency, and features required to integrate grinding processes into wider manufacturing systems.

“…Increasing the stiffness and optimizing arrangement of air bearings are the most effective way to enhance the machine's dynamic performance. It should be noted that in conventional precision machine design, the first natural frequency is expected to be higher than the machine operation frequency [15], for example, the spindle rotational frequency. However, it cannot be the case in ultraprecision micro milling machine, because the maximum spindle speed in micro milling machine can be up to 4000 Hz (240,000 rpm).…”

Ultraprecision machines with small footprints or micro-machines are highly desirable for micro-manufacturing high-precision micro-mechanical components. However, the development of the machines is still at the nascent stage by working on an individual machine basis and hence lacks generic scientific approach and design guidelines. Using computer models to predict the dynamic performance of ultraprecision machine tools can help manufacturers substantially reduce the lead time and cost of developing new machines. Furthermore, the machine dynamic performance depends not only upon the mechanical structure and components but also the control system and electronic drives. This paper proposed a holistic integrated dynamic design and modelling approach, which supports analysis and optimization of the overall machine dynamic performance at the early design stage. Based on the proposed approach the modelling and simulation process on a novel 5-axis bench-top ultraprecision micro-milling machine tool – UltraMill – is presented. The modelling and simulation cover the dynamics of the machine structure, moving components, control system and the machining process, and are used to predict the overall machine performance of two typical configurations. Preliminary machining trials have been carried out and provided the evidence of the approach being helpful to assure the machine performing right at the first setup

“…In this study, the first ten natural frequency and their vibration mode shapes were extracted for both configurations using the block Lanczos method. Table 1 lists the first ten natural frequencies and the description of the mode for the bench- design, the first natural frequency is expected to be higher than the machine operation frequency [14], for example, the spindle rotational frequency. However, it can not be the case in ultraprecision micro milling machine, because the maximum spindle speed in micro milling machine will be up to 4000 Hz (240,000 rpm).…”

Abstract:Using computer models to predict the dynamic performance of ultraprecision machine tools can help manufacturers substantially reduce the lead time and cost of developing new machines. However the use of electronic drives on such machines is becoming widespread, the machine dynamic performance depends not only upon the mechanical structure and components but also the control system and electronic drives. Bench-top ultraprecision machine tools are highly desirable for micro manufacturing high-accuracy micro mechanical components. However the development is still at the nascent stage and hence lacks standardised guidelines. Part 2 of this two-series paper proposes an integrated approach which permits analysis and optimization of the entire machine dynamic performance at the early design stage.Based on the proposed approach the modelling and simulation process on a novel 5-axis bench-top ultraprecision micro milling machine tool -UltraMill is presented. The modelling and simulation cover the dynamics of the machine structure, moving components, control system and the machining process, and are used to predict the entire machine performance of two typical configurations.
