This axes would determine the motion of the machine which is important in the manufacturing process. Additional features may be included in CNC woodworking equipments, like the automatic tool changer, spindle speed and the coolant. The automatic tool changer replaces the spindle automatically when needed. Others may have technical background, while others may be completely clueless. To help woodworkers, there are different websites and forum where they can interact with other woodworkers and ask them about their CNC router building experience. Hobby CNC wood routers are small and could be placed on the top of a table or counter. In turn, the controller converts these into varying voltages and currents that control the movements of the mechanical drive systems. Spindle The spindle is the part that does the actual cutting and is sometimes mistaken to be the actual router itself. It works by rotating a cutting tool (router bits) at different speeds depending on the material to be cut (wood, plastic, metals). CNC Woodworking And Shopbots When computers first arrived in the last quarter or so of the 20th century, it had started early on to take over some important functions in some of man s complex machineries and devices. It was only a matter of time when software programs like CNC and ShopBots would dominate the manual-driven industry of woodworking. The following is a short walk-through of some of the very important processes and tools of the craft. CNC Routers CNC Routers are the machines that are programmed to shape wood in specific and precise shapes and sizes. These files are also created by CAD/CAM programs. The old traditional routers are usually supervised by humans while CNC routers are totally automated. Others foresee further integration between CAD programs and the CAM software for the machine. This, experts say, will make the connection between product development and actual production easier. Others declare that CNC machining operations will be completed without repositioning the part. Powerful drive system Other experts predict that in the future there will be faster and more powerful drive systems for the CNC machine to be more accurate.
