Digitized Processing Track Generation of a Computer Integrated Multi-Functional 5-Axis Laser Processing System

Based on the computer integrated and flexible laser processing system, an intelligent measuring sub-system was developed. A novel model has been built up to compensate the deviations of the main frame-structure, and a new 3-D laser tracker system is applied to adjust the accuracy of the system. To analyze the characteristic of all kind surfaces of automobile outer penal moulds and dies, classification of types of the surface、brim and ridge(or vale) area to be measured and processed has been established, resulting in one of the main processing functions of the laser processing system. According to different type of surfaces, a 2-D adaptive measuring method based on B?zier curve was developed; furthermore a 3-D adaptive measuring method based on Spline curve was also developed. According to the laser materials processing characteristics and data characteristics, necessary methods have been developed to generate processing tracks, they are explained in details. Measuring experiments and laser processing experiments were carried out to testify the above mentioned methods, which have been applied in the computer integrated and flexible laser processing system developed by the Institute of Mechanics, CAS.

Hacia los orígenes de la literatura gastronómica: el calendario de Ananio (fr. 5 West)

[ES] El fragmento 5 West de Ananio, un yambógrafo del siglo VI a.C., es probablemente el primer ejemplo de literatura gastronómica en Grecia. En él se mencionan diversos alimentos indicando el mejor momento del año para su consumo, lo que lo convierte en un verdadero calendario gastronómico. Este tema será después particularmente importante en la medicina dietética, reapareciendo también en el personaje del cocinero-médico en la comedia.
