The Tool Path Generation Software System For 2Dimensions Numerical Control

With the development of science and technology, great changes have taken place in the manufacturing. Every kinds of advanced manufacture technology are applying in the manufacture system now. In the system of modern manufacture, NC machining equipment is the core of manufacture system and the important subassembly of the modern manufacture system. The NC machining an important link that process the inside is a quality to design the tool path, tool path design the quantity, will affect directly the spare parts process the quantity and process the cost.In this paper to the 2-dimensions arbitrarily the shape flat surface carries on tool path generation, the adoption have to of closing wreath carry on the description to the slot form boundary, use offset curves method make tool path generation. Not only constitution offset curves but also analyzed of Bezier curve and B-spline curve ,and use the diagram example was good to explain it each from of characteristics. By study NURBS curves bring two method about offset curves.This paper became a software system and can carry on the auto that the tool path generation.
