Consider the following factors that are needed to be met time to learn the machine s software, time to learn proper dust collection and hold-down techniques, and time to train new employees. The CNC machine can only do what its operators want it to. While the CNC tool can do the tasks more accurately than humans, it still needs regular maintenance and an operator committed enough to learn everything about it. In a few minutes, everything is done by the ShopBot the sawing, drilling, and grooving. Mind shift In this new scenario, instead of involving the use of a number of individual tools, the thinking is now shifted to the design and planning phase. It is important to know that CNC have the capabilities for complex and precise cutting and carving. This is then converted into digital signals and relayed to the CNC controller. 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. These complicated moves are programmed into the machine and are carried out with zero error. 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. Since, the wood work designs are controlled by a computer software/program, it could be changed to suit manufacturer and customer demands without spending too much effort. They could even develop designs which the competition may find difficult to replicate. Automation also reduces the risk of human error and the time spent in correcting such errors. If you are a hobbyist, you do not have to worry about the size of the equipment, since the CNC wood lathes are available in different sizes. If you are a small hobbyist, then there are portable models which can be easily mounted on a table or a countertop. 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.
