Implicit Function in the form of five-axis
machining of cylindrical surfaces
Abstract Five-axis CNC machining technology in the development of a fairly rapid pace in recent years, especially for complex surface machining has played an irreplaceable role . There are a lot of the complexity of the project cylinders, 5-coordinate high-performance processing can achieve the required shape, through the cylinder differential equation is derived to explore the processing line and the line when the tool between the local shear of the basic theory of touch, and dwelt at length on the tool Under these conditions the problem of the coordinates. But the technology at the global level has not been universal, the article analyzes the current five-axis CNC technology at the global level are prevalent, and difficult to resolve the problem, an analysis of the market's five-axis machine tool industry the demand for CNC machine tools and the development of five -axis CNC technology, the need for, and made the prospect of their application. To touch (high-contact) principle applies to surface processing, such as from contact with the tool along the straight line on the bus, the bus should be along the straight tool is processed surface of the asymptotic direction. Exhibition of non-ruled surface, ruled line of the normal vector of each point in different directions, and the Spur Line bus every point the same direction as normal vector, so it may have been cut.In accordance with the principle of touch to determine when the contact line is not along the straight generatrix tool, the tool the best posture. Touch and 2-order theory, the best tool to determine the best exposure to posture and direction. 2-order surfaces can be carried out and 3-order contact.
