Specialty routers There are also CNC routers which are dedicated on special designs, they are called specialty CNC routers. Samples of specialty routers are engraving machines, 3D engraving machines and PCB routers. The PCB router is used to create circuit boards. Several CNC features would include having separate heads. However, some builders feel that following the directions, exactly as they are, fails to meet their needs. Since they have to follow the plan, considerations in designs and sizes (or whatever the builder needs or wants) may not be accommodated by the plan. This would leave builders operating with CNC routers that they do not want or need. How does it work? CNC machines are programmed and controlled by a software. The design that would be followed by the machine is used by the CAD module. It is the Computer Aided Manufacturing (CAM) which ensures that the movement of the motor or the machine is controlled. Once the machine is already set-up, using it would be easy. Will there still be changes or development? Definitely, yes. With technology continuing to progress, there is much advancement on computer knowledge. CNC machines are continuously being developed to accommodate both manufacturer and customer demands. Shifting from manual to mechanized manufacturing through CNC woodworking machines, showed that manufacturers were able to profit from the changes and at the same time, meet customer expectations. One of its most simple examples would be Paint which is present in Microsoft Windows. CAD software would allow you to create high-quality and professional furniture designs on your computer. There are different woodworking programs or software that would allow you to work with different wood and furniture designs. Advantages and benefits Because programming does not put in margins of error, CNC lathes produce uniform products looking exactly like the original. Duplicates are all identical with no noticeable variations in them whatsoever. What come out unmatched as well are the CNC lathe s speed and the accuracy in the manufacture of these desired pieces or products.
