In the last decade, parametric and generative design techniques become quite popular for form-finding strategies or for pushing automation in design processes. Nevertheless, these techniques could be applied in engineering processes as well in order to improve the effectiveness and the efficiency of manufacturing processes in BI (building industry). Focusing on the case study of GLT (glued-laminated timber), this paper shows the procedure of programming a parametric algorithm adopted by authors that pursues two specific design intents: reducing the usage of unneeded high-quality raw material and improving the efficiency of production processes by producing DF (digital fabrication) contents for standard production systems of GLT. According to different European and international standards, thanks to FEM (finite element model) simulations and curvature analysis, the algorithm allows saving at least 33% of high-quality raw material and, according to early first surveys on a standard production system, 30% of operation time among product engineering-processes. 展开更多

The paper points out that the science and technology, social productivity and economic form are the decisive strengths in facilitating the reformation of the production method of the manufacturing industry. This kind of strength happens through making an influence on the theory of management and science. It analyses the stage and the characteristic of the development model of manufacturing industry of human society, and on this basis does the detailed research on the several patterns of the advanced manufacturing theory and practice: the computer integrated making, concurrent engineering, lean production, agile manufacturing, planning of enterprise resources, global manufacturing. Finally, it thinks that the development model of the advanced manufacture theory and practice embodies a continuous curve of the technical innovation, which is on the basis of the theory of management science. 展开更多

A new precise actuator is proposed,which is ac-tuated by the impact force of an end-loaded piezoelectric bimorph cantilever,and bears two degrees of freedom for translation and rotation.The dynamic characteristics of the piezoelectric bimorph were analyzed by FEM,and are fur-ther proved by experimental tests.A new control system for the actuator was put forward and tested,which is called the fixed-frequency with adjustable voltage.In addition,the actuator’s performance of translation and rotation were both measured.The results demonstrate that the actuator is char-acterized by a simple structure,large movement range,strong driving ability and high positioning resolution.Its cost is estimated at only 1%of the traditional impact actuators. 展开更多
