CNC manufacturing automation technology as the foundation and key technologies, has become the measure of a country's level of industrialization

With advances in computer technology and the development of global manufacturing, numerical control technology as the basis for manufacturing automation and key technologies, has become the measure of a country's level of industrialization, an important indicator of overall national strength. CNC technology CNC programming  Polycrystalline diamond  as an important component of the current CNC technology has been the research focus. In this paper, CNC milling programming theory and its application problems, combined with fifteen national key scientific and technological project "product design CAD ​​software", to complex multi-surface  abrasive wheels  programming roughing, finishing and complement the related theories and key processing technology for the systematic study and practice. Roughing tool path generation for high efficiency and stability problems, the paper roughing area boundary extraction methods and cutting area boundary  abrasive grinding  technology to conduct in-depth research, the Z-map model based on rough cutting zone generation algorithm. Through efficient tracking method to extract the boundary cutting area boundaries, improve the efficiency of the roughing tool path generation and automatic identification using the boundary description of the tree cutting nesting areas, improve the stability of the roughing tool path generation. The traditional tool path interferometric processing algorithms often apply only to specific tool types, can not be applied to a variety of tool types and the lack of scalability.
