Processing Information

In allusion to the status of the expression and integration technology of the three-dimensional CAPP processing information, a machining process information expression and integration method was put forward, which was process-oriented and based on the three-dimensional model of products. The machining process object was represented by the processing structure tree, and the processing information was expressed and collected in the three-dimensional situation. Finally，a prototype system was developed to illustrate the feasibility and validity of the proposed method.

Abstract Does the materiality of a three-dimensional model have an effect on how this model operates in an exploratory way, how it prompts discovery of new mathematical results? Material mathematical models were produced and used during the second half of the nineteenth century, visualizing mathematical objects, such as curves and surfaces—and these were produced from a variety of materials: paper, cardboard, plaster, strings, wood. However, the question, whether their materiality influenced the status of these models—considered as exploratory, technical, or representational—was hardly touched upon. This article aims to approach this question by investigating two case studies: Beltrami’s paper models vs. Dyck’s plaster ones of the hyperbolic plane; and Chisini’s string models of braids vs. Artin’s and Moishezon’s algebraization of these braids. These two case studies indicate that materiality might have a decisive role in how the model was taken into account mathematically: either as an exploratory or rather as a technical or pedagogical object.
