The size would be based on the amount of work you will be putting on the machine and kinds of wood pieces you will be making. Since CNC lathes would turn or spin, it is important to follow safety rules when using it. Avoid wearing loose-sleeved shirts, watches, bracelets or anything that the rotating CNC lathe may catch. If you are a hobbyist or catering to small orders, then getting a do-it-yourself CNC router would help you in your production and increase sales. Though the benefits may be great, there are still woodworkers who are not confident enough with their CNC router building skills. Others may have technical background, while others may be completely clueless. For those who have been doing woodwork manually, the price of CNC equipment may be surprising and the costs of upgrading the system may cause some serious dent on your savings. Would there be another way of increasing productivity without spending too much? There is a good alternative for buying new CNC woodwork, buying used ones. These CNC machines are operated by computer files created by CAD/CAM programs. A number of new CNC machines have built-in design programs. This way, the programmers can make changes on the fly and design pieces with the machine. The following is a short walk-through of some of the very important processes and tools of the craft. Some machines specialize in cutting at different and complex angles as well as being able to work on exotic materials with impressive amounts of power to boot. Some are small mills for smaller parts, and some are lathes that can cut whichever angle is needed. Today, there are mills that have beds that move at programmed angles in such a way that angled cuts or drills are done according to the design, and with pinpoint precision. Materials are cut with a saw, work the drill press to put in the holes, and using the router to do the edge treatment. With a ShopBot, the first job is to design the part or parts, including all of the features like the holes and the grooves. Next is the loading and securing the material. In a few minutes, everything is done by the ShopBot the sawing, drilling, and grooving.
