How Does it Work?

This image has an empty alt attribute; its file name is CNC-machine-for-woodworking-1024x576.png
CNC machines are fully automated. All they need is digital files with the instructions about cutting trajectories and tooling. Design or machining processes require many tools to produce a certain part.
Machinists can build digital tool libraries that interface with the physical machine. Such machinery can automatically switch tooling based on the digital instructions, making them manufacturing workhorses.
The CNC machining process starts with designing the parts in CAD software. The 3D model determines the necessary dimensions and properties of the final part.
Some of these programs come in CAD-CAM packages, so the flow can continue in the same programs. Otherwise, CAD models are fed into designated CAM software. If both CAD and CAM are from the same product family, no translation of files is necessary. Otherwise, the CAD files need to be imported. CAM software prepares the model for the whole fabrication process.
First, it checks the model for errors. Then it creates a CNC program to fabricate the physical part. The program is, in essence, a set of coordinates that guides the cutting head during the manufacturing process.
The third step is choosing the right parameters. These include cutting speed, voltage, RPMs, etc. The configuration depends on the geometry of the part as well as the available machinery and tooling.
Lastly, the software determines the nesting. Nesting means the orientation and placement of parts relative to raw material. The purpose is to maximize material usage.

How Big Are CNC Routers?

In terms of size, older and industrial-strength models of Cheap CNC Machines are extremely large and can take up a good amount of space. However, newer desktop cheap CNC milling machines are much smaller and can sit right on a large table. While these desktop machines are certainly not as powerful as their industrial-size counterparts, they are ideal for home use and can literally connect with a home computer. A user can simply use the software on their home computer and program the desktop CNC router to perform specific production functions.

Types of Different CNC Machines:

High powered Spindles
Complete User Interface

Mid Range CNC Routers

The next step down from an industrial CNC router would be a midrange CNC router. The precision and accuracy of these machines are not necessarily less than that of an industrial type. They often use the same internal components. However, these machines are usually much smaller and lighter than their big brother counterparts. Mid-range CNC routers usually run from desktop CNC router size to a full 4 foot by 8-foot layout. These machines are popular with hobbyists and smaller businesses with less production.

Hobby CNC Routers

Hobby CNC routers are usually referring to the homemade CNC router. These machines are usually designed and built by the owner. There are many plans that may be bought or downloaded. These designs are as unique as the person designing or building them. Each machine is different and is usually designed around the parts and budget available. There are many homemade CNC woodworking routers out there that rival the industrial ones.

Multi-Axis CNC Routers

All CNC routers have 3 axes and may cut in 3 dimensions. However, some applications may require more flexibility. This is where four and five-axis CNC woodworking routers four and five-axis CNC woodworking routers come into play. A 4 axis CNC router usually means that either the spindle head may rotate in one additional plane or that a turntable of sorts is attached to the cutting bed.

A 5 axis CNC router means that the spindle can rotate in 2 additional planes. You can see this well in the picture to the left.

4 and 5 axis CNC routers offer the ability to cut a true 3D part. A traditional 3 axis machine is limited as to the depth in certain dimensions. These machines are popular with rapid prototyping and artistic industries. Be expected to pay a hefty price for these additions. They require special controllers and software and are more difficult to learn.
02.

Plasma

CNC plasma cutters cut 2-dimensional wood and metal and do not need as much power as cheap CNC milling machines. They may have similar size and setup with routers but they fly above the table with a plasma torch instead of grinding around a spinning tool in the material. These machines use the plasma torch to penetrate sheet metal or wood.

03.

Laser

CNC laser cutters work like the plasma cutter but these use a laser to do the cutting. These laser cutters are often great for cutting metal, plastic, and wood. Each of these materials requires a different strength of laser suitable for the material’s thickness and hardness.

04.

3D Printer

3D printers make use of Affordable CNC Machines technology and operate with identical technology as CNC lasers, however, it performs additive machining as opposed to subtractive machining. Other previously mentioned machines require a solid piece of material and remove bits of it to produce the desired part. The opposite happens with 3D printing as it starts with a blank canvas and builds a part layer by layer.

05.

Pick and Place

These Cheap CNC Machines consist of numerous nozzles that pick up electrical components for electronic equipment and put them in the preferred location. Pick and Place Cheap CNC Machines are frequently used in the construction of computers, tablets, and mobile phones.
