Basics
First, it's important to understand the forefather of the computerized router: the handheld router. This common tool features a motor that usually has a variable speed setting, a tapered spring that creates the necessary friction to keep the tool steady, and an adjustable height that is fixed or what is called "plunge". It helps to understand the function and movement of this non-computerzied version before using the more technological version. This can be said for almost any tool, as the handheld version allows you to know how to prep the computerized one.
Once the handheld version is understood, it's time to move on to the computerized one. A cnc router controller is used for the computerized CNC. It is often retrofitted via a "kit". It helps determine the programming of the CNC. The manufacturer of the kit determines the properties of the kit, from look to ability. The kit is an essential part of retrofitting any router.
Bits
A CNC relies on router bits that consist of four pattern parts called flutes. The four flute parts are straight flute, up spiral, down spiral, and compression.
A straight flute bit is an all round piece that is the best at removing chips. An up spiral works wonders by tearing out the thin veneer on plywood. A down spiral does not perform tear out and is slow for better control, plus lacks chip removal. A compression flute combines the up and down bit into one bit.
Because these flute bits each command distinctive capabilities, it's a good idea to keep all four on hand. Some carpenters assume that owning the straight flute bit and the compression bit will suffice. That's not the case. Just because the compression combines the up and down spirals, it doesn't necessarily replace them in certain instances. There will be some jobs that requires the unique proponents of each bit.
After going to all the trouble of computerizing this tool, it makes sense to keep it in the best shape. Therefore, maintenance proves essential to the function of a CNC.
If there's a lack of calibration, then whatever is programmed is not going to be what the tool produces. In other words: Without proper input, the output is kaput. Any carpenter knows that tool maintenance is essential. Therefore, don't forget this just because a tool is electronic and programmable. Maintenance is still critical.
A CNC can make all the difference in how a carpentry shop produces its goods, increasing business via exceptional final products. Success comes naturally to shops that understand and refine their use of the CNC.
