“…This microfactory paradigm is closely linked to microrobotics, covering micromanipulation tools, micro-robots and micro-conveyors. One widespread requirement for all these devices is the need for precise movement, where accuracy in the order of the nanometer is often sought, together with a long travel range, large payload capacity and low energy consumption [3][4][5]. Different actuation systems, such as electrostatic, electrothermal, electromagnetic, pneumatic or piezoelectric, can be used to develop planar motion in micro-conveyors.…”

This paper reports the design, fabrication, and performance of a hybrid piezoelectric planar micro-conveyor based on Micro-Electromechanical Systems (MEMS) bridge resonators and featuring 3D-printed vertical legs. The device includes two cooperating silicon plate resonators with an area of 5 × 1 mm2, actuated by an integrated aluminum-nitride (AlN) piezoelectric thin film. An optimally designed array of 3D-printed projection legs was attached to the plates, to convert the standing-wave (SW) vertical vibrations into horizontal rotations or translations of the supported slider. An open-loop control strategy based on burst-type driving signals, with different numbers of sinusoidal cycles applied on each of the resonators, allowed the cooperation of the two bridges to set up prescribed trajectories of small flat objects, up to 100 mg, with positional accuracy below 100 nm and speeds up to 20 mm/s, by differential drive actuation. The effect of the leg tip and sliders’ surface finish on the conveyor performance was investigated, suggesting that further optimizations may be possible by modifying the tribological properties. Finally, the application of the micro-conveyor as a reconfigurable electronic system, driven by a preprogrammed sequence of signals, was demonstrated by delivering some surface-mount technology (SMD) parts lying on a 65 mg glass slider.

“…Therefore, research on the process planning method for part families in reconfigurable manufacturing will be of great significance for the reasonable and effective design of RMTs and RMSs [10]. At present, there has already been a lot of research on reconfigurable manufacturing system and the modular design of machine tools [11][12][13][14][15][16][17][18][19]. Among the research, the concept of the delayed reconfigurable manufacturing system (D-RMS) was proposed to improve the convertibility of RMSs by grouping parts with common former operations into the same part family and selecting appropriate machine types including dedicated machines, flexible machines, and reconfigurable machines [12].…”

“…According to the production demand, the study of reconfigurable drilling machine selection and process parameter optimization was carried out [14]. A new class of reconfigurable parallel kinematic machines [17] and reconfigurable micro-machine tools for desktop machining micro-factories [18] were designed. A method for selecting RMT modules based on RMT ontology was proposed [20] in which the appropriate RMT modules were selected according to the established knowledge base, and the selection of RMT modules was studied according to RMT performance indicators.…”

Reconfigurable Machine Tool Design for Box-Type Part Families

The reconfigurable manufacturing system (RMS) is a new manufacturing technology and paradigm that resolves the contradictions regarding high efficiency, low cost and flexible production in the mass production of part families. Reconfigurable machine tools (RMTs) are the core components of RMSs. A new approach is proposed for the design of RMTs, which is closely related to the process planning of a given box-type part family. The concepts of the processing unit and the processing segment are presented; they are not only the basic elements of the processing plans of machined parts, but also closely related to the structural design of RMTs. Processing units created by processing features can be combined into various processing segments. All the processing units of one processing segment correspond to the machining operations performed by one RMT. By arranging the processing segments according to the processing sequence, a variety of feasible processing plans for a part can be obtained. Through analysis of the established similarity calculation model for processing plans, the most similar processing plans for the parts in a given part family can be determined and used for the structural design of RMTs. Therefore, the designed RMTs can achieve rapid conversion of processing functions with the least module replacement or adjustment to realize the production of the parts in the part family. Taking the production of a gearbox part family as an example, the validity of the presented method is verified.
