At the 12th China International Machine Tool Show (CIMT2011), a uniquely shaped processing sample, “Wall Street Copper Bullâ€, earned the attention of visitors. In the impression, the samples processed at the machine tool exhibition are mostly molds or mechanical parts. The display of such “alternative†art processing workpieces not only reflects the uniqueness of the exhibitors, but also shows that the domestic machine tool manufacturing industry is at high speed and high. Accuracy has evolved to a new level. It is reported that this "Wall Street Copper Bull" symbolizing strength and courage is closely produced and produced by the British company Delcam and Shenyang Machine Tool Factory. This cooperation, in addition to perfectly reflecting the strong alliance of two well-known enterprises, fully demonstrates Delcam's complete and powerful digital advanced manufacturing technology for the art copying industry.
Only one month after the launch of CIMT2011, Miao, the manufacturing department of Shenyang Machine Tool Plant, came to the Delcam Beijing headquarters, hoping to process some exquisite handicrafts for CIMT as a sample exhibition. The reason why she chose Delcam, Miao said: "Delcam and Shenyang Machine Tool have successfully cooperated in the 4th National CNC Competition last year. The high-speed and high-precision 5-axis machining center developed by Shenyang Machine Tool (CCC model) is the 4th The CNC contest selected five-axis machine tools. At the time, there were more than 80 machine tools on the field. As the software supplier designated by the competition, Delcam PowerMILL's post-processing integrity and safety left a deep impression on me. I think Delcam The processing software can make the machine work safely and give full play to the high-speed and high-precision characteristics of the equipment. Moreover, I also know that Delcam's product line is very long. In software, it can realize prototype proofing, digital manufacturing simulation, high-speed, five-axis machining. Waiting for a new manufacturing concept; more importantly, Delcam software can be seamlessly integrated with the device, providing a program interface that does not require any modifications."
“Wall Street Copper Bull†is a symbol of Wall Street in the United States. Shenyang Machine Tool Plant hopes to process the “Wall Street Copper Bull†crafts to reflect the “mainion, innovation, breakthrough†business melody, and also reflect the five-axis machining of Shenyang Machine Tool Plant. Advantage. Since Shenyang Machine Tool Factory provides "Wall Street Copper Bull" crafts, there is no corresponding digital model, so Delcam provides five-axis programming by reverse engineering - triangular grid data (STL) editing - triangular grid (STL) The complete program.
"Wall Street Copper Cattle" Crafts
The first is the reverse engineering of the "Wall Street Copper Bull" artwork. The "Wall Street Copper Cattle" handicraft was scanned by a photographic 3D scanner to obtain point cloud data. In 3D scanning, it is necessary to spray a developer (colored penetrant) on the surface of the copper bull, and paste multiple identification points to better generate point cloud data and fit the point cloud. In just one hour, the scan was completed and 3 million points of point cloud data were obtained.
The point cloud data is then imported into Delcam's forward/reverse hybrid design system, Delcam PowerSHAPE Pro, to generate high-precision triangular meshes from point cloud data. Delcam PowerSHAPE Pro has a friendly input and output interface that supports point cloud data reading in multiple formats. In addition to the standard formats such as ASCII, IGES and NC, special data formats are available for different scanning devices. Using Delcam PowerSHAPE Pro's powerful and powerful point cloud data calculation, processing and editing tools, you can convert 3 million points of point cloud data into a triangular grid (STL) in just five or six minutes.
Since the marker points also generate a triangle mesh, these marker points need to be deleted, and then these regions are filled in the direction of the loss of the adjacent boundaries.
