The Analysis on the Application of CAD/CAPP/CAM in Die Designing and Manufacturing

Die design and manufacturing are organic unity, primarily owning to its own characteristics. On account of the fact that curves and surfaces constitute the main inner part of die, CAD software can be applied in die designing, plotting and three-dimensional modeling. Additionally, CAPP software could be applied in the scheming of die processing while CAM software in the imitation of die manufacturing. As the intensive research and development of CAD/CAPP/CAM, computers not only offer spacious room for die design, modeling and application but also bring about great prospects for research and development of computer software.

Koch Snowflake

Fractals are geometric objects, each part of which is similar to the whole object, so that if we take a part and increase its size to the size of the whole object, it would be impossible to notice a difference. In other words, fractals are sets having scale invariance. In mathematics, they are associated primarily with non-differentiable functions. The concept of "fractal" (from the Latin "Fractus" meaning «broken») had been introduced by Benoit Mandelbrot (1924–2010), French and American mathematician, physicist, and economist. Mandelbrot had found that seemingly arbitrary fluctuations in price of goods have a certain tendency to change: it turned out that daily fluctuations are symmetrical with long-term price fluctuations. In fact, Benoit Mandelbrot applied his recursive (fractal) method to solve the problem. Since the last quarter of the nineteenth century, a large number of fractal curves and flat objects have been created; and methods for their application have been developed. From geometrical point of view, the most interesting fractals are "Koch snowflake" and "Pythagoras Tree". Two classes of analogues of the volumetric fractals were created with modern three-dimensional modeling program: "Fractals of growth” – like Pythagoras Tree, “Fractals of separation” – like Koch snowflake; the primary classification was developed, their properties were studied. Empiric data was processed with basic arithmetic calculations as well as with computer software. Among other things, for fractals of separation the task was to create an object with an infinite surface area, which in the future might acquire great importance for the development of the chemical and other industries.
