Various process parameters and project data can only experience with engineers and manuals

Geometric modeling and tool path generation is the implementation of two key technologies of CNC machining, including CNC tool path geometry is the foundation of the parts CNC machining accuracy is only reasonable under the premise of the tool path can be guaranteed. Tool path planning is reasonable or not, not only directly related to the cutting efficiency, precision, machining interference, but also affect the dynamic performance of the machine and tool life. Currently, in the actual  ubic boron nitride  toolpath  synthetic diamond  entirely through human-computer interaction by hand, over-reliance on the experience of engineers; various process parameters and project data can only experience with engineers and manuals, failed to achieve automation. Mainly based on actual production needs for tool  Polycrystalline diamond  path planning, and Shenyang Brilliance Jinbei Automobile Company HIACE a cover for the sample studied. Application of the principle of reverse engineering, the use of hospital laboratory LK G90CS15.10.8 coordinate measuring machines on the physical sample freeform surface data collection, get a lot, scattered point cloud data.

Ceramic cutting tool applications with CBN difference

Cubic boron nitride ceramic materials science in the category, although attributed to, but because of CBN, SIN, Al2O3, SiN material difference in performance, cubic boron nitride ceramic cutting tool less Diamond blade and hardness. Therefore, according to its hardness and toughness of the differences in cutting ubic boron nitride less than 50HRC small depth of cut and feed small case hardened steel workpiece, ceramic tool is a better choice. Cubic boron nitride cutting tools better suited to the workpiece hardness is higher than 50HRC situation. In addition, note that the boron nitride ceramic tools and abrasive grinding mosaic roughing blade rarely used, only some grades of boron nitride inserts such as BN-S20 capable roughing and interrupted cuts.
