Experts observed that advancement in software, the 4 and 5 axis capabilities, and other related technological progressions are born faster and that the machinery is getting more versatile. For most shops and factories, CNC router and machining centers are the hearts and souls. Today s five-axis routers allow the customers complete flexibility without requiring expensive aggregates. Compared with manually done pieces, there are minor variations among the finished products. While the CNC finished work pieces are almost the same. Simplicity Although, they may look complicated, CNC machines are easy to operate and learn. There are machine controls which make manufacturing processes easy. It is unique since it is based on the needs, models, available parts and budget of the owner. It can be easily placed on counters and table tops. Most hobbyists would prefer having a hobby CNC router compared with acquiring midrange or industrial router. Hobby CNC router is inexpensive compared with the industrial router. Basically, the main advantage of CNC machining is the improved accuracy, efficiency, productivity and overall safety. Operators are less at risk because human interaction is decreased. Many applications of CNC machining have the machines operating unmanned for significant periods of time. The software automatically stops operations and asks for human help only in cases of errors and other problems. Like the good old traditional router, the new CNC router also moves in 3 directions (usually called X, Y, and Z directions.) The longest is the X axis which runs from front to back. The Y axis goes from left to right while the Z axis goes up and down. Moving in perfect synch with each other, these routers can carve some very complex shapes with flawless precision and accuracy. With CNC, they are able to produce some amazing pieces with complex and sophisticated shapes that enhance their work. Computer Numerical Control Basically, CNC means computer numerical control. When applied to woodworking, it simply means using today s computer technology and applying it into the craft.
