Mechanization of the processes Since the manual manufacturing process is replaced with automation, little supervision is needed from the operator. This would allow the operator to attend to other tasks. Mechanized processes would reduce product mistakes which are caused by human error brought about by fatigue or lack of skill. The codes which are converted by the computer software would then send or relay it to the CNC controller which would control the motors and drive systems. The part of the CNC wood router which performs the actual cutting is called spindle. To classify the spindle, horse power (in English units) and watts (SI units) are used. Given these benefits, it is very likely that businessmen, from small businesses to large scale woodwork business, will use CNC machines for their production. How does it work? CNC machines are programmed and controlled by a software. The design that would be followed by the machine is used by the CAD module. 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). When cutting metals (usually the non-ferrous types like aluminium), there is a coolant system used to cool the materials and the tool itself. Hobby CNC router The Hobby CNC router, which is homemade, is designed and built by the owner. 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. Should one choose a dedicated machine or some multi-function model? What can the performance be like? Can the machine justify its price? The underlying aspect of all these questions is the fact that the smaller guy most likely has a smaller budget and naturally fidgety. Commitment However, the first consideration when thinking of buying a CNC machine is a simple commitment.
