Is the key step in the CNC carving carving design drawing and CNC programming, simple design can directly by AutoCAD software rendering, but it's hard to sculpture design complicated by drawing software, then usually make the sculpture carved by hand samples first, and then use 3 d scanner to samples recorded data to a computer system, into a 3 d data model.
3 d scanners can be divided into two categories, contact and non-contact, non-contact and divided into two categories, laser scanning and photographic, laser scanning is used for planar CNC engraving machine, photographic type is used for 3 d CNC engraving machine more. Laser scanning is a beam of a laser beam (issued by the scanner Or light) Exposure to the measured object surface and is moving on the measured object, use a digital camera to receive the reflected beam, and the distance between the object point, thus the surface shape data. 3 d laser scanner is mostly installed in the plane of CNC engraving machine power head, As shown in figure 1) , through the movement of the head to complete scan, by adjusting the measurement precision of the scanner when work power head and movement speed for different scanning effect, generally speaking, the workpiece surface engraving is fine, the precision of the laser scanner Settings should be higher, scan speed should be slower, in order to get the more elaborate point cloud data. Due to scan for planar mobile way, thus the type of scanner is mainly applicable to surface scanning artifacts.
figure 1 laser scanner photographic scanner is similar to the photographic camera within the field of vision on objects, different intake of a camera is a two-dimensional image of the object, and the obtained is the object's 3 d scanner. It through a series of grating projection grating launcher stripe to the surface, through the surface deformation, and then with the help of two digital camera photograph grating interference fringes, using optical pictures positioning technology and grating measuring principle, get the complete point cloud on the surface of the workpiece, based on the marked points matching or feature, can get 3600 each azimuth data object, thus is more suitable for three-dimensional photographic scanner or placed TiGong scanning. Photographic type 3 d scanner, but make it stationary and handheld ( As shown in figure 2) , the overall price is laser scanner.
figure 2 camera type 3 d scanner
the 3 d scanning data of point cloud data, need to pass to remove noise and more visual alignment, compaction, surface reconstruction and so on steps to get the 3 d model of the sample. Model after data were treated with dedicated software can guide people to the CAD/CAM software editor for subsequent processing, such as setting tool motion trajectory, and generate CNC engraving machine can identify the NC code.
