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. Through the ages, it slowly developed into a specialized craftsmanship mostly mastered by men. Today, woodworking is into another level with the introduction of CNC not too long ago. What is CNC? Once a taboo subject among woodworking professionals and hobbyists alike, CNC is now accepted as an indispensable aid in the craft of woodworking, carpentry and other related fields. There are different cutting bed designs, the most popular would be the T-slot and the vacuum table. The efficiency of the cutting bed would be based on what kinds of materials and cut are made. For example, T-slot cutting bed could hold different kinds and sizes of materials, but they are not ideal for speed cutting. The elegance and the beauty of its masterpieces at that time had been duplicated only sporadically during the ensuing centuries. Until, of course, the advent of the computer-aided CNC woodworking. CNC or computer numerical control machines are machine tools that are automated and controlled by resident computer programs. Benefits The biggest benefit CNC machines have is their being able to make parts and pieces to the exact specifications programmed into its computer. This greatly helps lighten up human fatigue caused by common human errors on projects done manually in the old traditional ways. With no human intervention in the process (except in the pre-programming), the manufactured parts are made in exactly the same way each time. CNC machines could adapt easily to different materials. Flexibility could also mean that CNC machines are quick to reprogram to create new products. They could easily shift from one product to another. Although there are major advantages of using CNC machines, it is not that perfect. They also have limitations.
