CNC In Modeling And Prototyping

CNCs in Modeling and Prototyping

A CNC tool can be used in many ways for prototyping, reverse engineering and modeling.  As a rapid-prototyping tool, a OMNI can machine foam, wood, plastics and aluminum to efficiently create prototype and reproduction parts.  With a CNC tool, you will typically be doing subtractive prototyping, but it is a process that lets you machine quickly in materials that are similar to the end product.  Large projects can also be done using additive layering techniques that allow substantial models to be constructed even beyond the machinable area of the CNC.

The sheer versatility of a CNC wood router in a prototyping setting is nothing short of astounding.  With a good CAD/CAM package and a CNC router, it is possible to create master models with the proper draft for secondary operations such as casting, vacuum forming, sheet metal stamping and FRP composite construction.  These types of models are typically 2.5D, meaning that they don’t have undercuts and can be completely machined on a 3-axis CNC on one side of the material.  In addition, advances in affordable hardware and software now give you the ability to cut double-sided parts using 3 axes and carve true 3D parts on a machine equipped with a 4th axis, rotary indexer.  The indexer can be used as a lathe to cut simple profiled turnings or elaborate 3D parts and relief carvings, giving many of the advantages of a 5-axis tool at a fraction of the cost.

Mold Making

Aside from playing a key role in subtractive methods of creating models, the CNC is also instrumental in preparing molds for creating parts.  Thermoset plastic parts can be created in conjunction with a rotational molding machine.  Masters can be created on the CNC, molded and setup to produce thin-walled and hollow models not possible using a subtractive strategy. A CNC router coupled with the proper mold making equipment is a potent combination spanning many industries and applications.

Reverse Engineering Processes

While CNC wood routers excel at producing accurate parts with speed and efficiency, they also excel when it comes to reverse engineering an existing 2D or 3D part.  The digital version of the part can then be toolpathed to produce an exact duplicate, or transformed into an updated version by modifying the scale or geometry to create the required part. Using the optional rotary indexer, odd-shaped and cylindrical 2D & 3D parts can be digitized a full 360° with the same straight-forward method as a standard 3-axis tool equipped with a probe.

Use CNC Wood Router For Mold Production

Dianel Dean and Ryan use cnc wood router to produce a mold for their project " Underground Sound".  Their project is with some giant flowers, which allow people to hear the sound from earth via megaphones.

The mold for the megaphone was designed in Rhino and imported into Enroute software as an .STL. They created all the toolpathing in EnRoute. The form was cut in pieces on the CNC router mold using a 1/2" wide by 3.5" tall ball nose bit.  Daniel glued together panel board to be 3.5" deep and divided the megaphone up into various sections. Once cut, the sections were glued together to create the final form, which was then used as a mold for the fiberglass.

The following is the final project at field.

Laser Cutting Machine Cut Foam Material

Cutting foam by laser cutting machine can be resulted very fine cutting edge. The laser cutting machine's un-touching cutting way ensures the clean cutting edge, this is very important for foam cutting.
If you are engaged in foam cutting industry, you can try to use laser cutting machine to cut foam to see, and you will find that the foam cutting is so easy, clean, fast and fine quality.

Comparing traditional foam cutting way, laser cutting foam machine's advantages:
1. Fine Engraving: The accuracy of laser engraving machine is with rather higher accuracy than cnc wood router bits. Its accuracy could up to 0.02mm. With laser engraving machine and laser cutting machine, we can work out rather beautiful words and imagine on acrylic.
2. High Working Efficiency: Laser cutting machine and laser engraving machine is with high engraving speed, rather faster than traditional saw. 
3. Easy operation: laser engraing machine and laser cutting machine is just like laser printer. There is no much high requirement to operator, very easy to learn it and get starting.
4. Low cost. Unlimitless on the processing quantity.

CNC Plasma Cutter VS CNC Wood Router

CNC Plasma Cutting VS CNC Wood Router Cutting

1. Cutting Material Difference
CNC Plasma Cutter is mainly for cut metal material, such as aluminium, metal, steelless.
CNC wood Router can work on more material besides metal. It also can work on plastic, acrylic, wood, glass etc.
2. Cutting Way
CNC Plasma Cutter cut metal by hot energy. The energy is powered from Plasma Generator, with the engergy, the torch can cut through metal up to 20mm around.
CNC router cut material by its bits. The bits are designed for different material, different shape etc. 
3. Application
Whatever cnc wood router or cnc plasma cutter, both machines are used in industrial industry and sign, advertising industry. And both machines are widely used.

Choose What To Cut Aluminium

How to cut aluminum? By China CNC Router or waterjet? Sheet size would be 4' x 10' with a thickness of 1/4-1/2". Such aluminium is for fabricator, many companies use plastic and wood laminates. it would be a better investment for the company to buy a machine that could do multiple things as opposed to a water jet or china cnc router which will only cut steel and aluminum.

You can cut aluminum with a china cnc router. The China cnc router needs to be set up with lubricant spray and the vacuum pump cannot be one with graphite vanes - if the lubricant sucks through the vacuum to the pump and gets on the vanes, they are toast. Routers are not really made for cutting metals, however, the key word above is "can." For working metal, it is better to get a mill, as they are engineered for metal work in terms of feed rates, rotation speeds, adequate lubricant flow, recycling lubricant, etc. Hold downs are usually mechanical using t-channel (rather than vacuum, as is typical on  China CNC routers). Routers' rotation/hp ratio are typically best at higher rotational speeds (like 18,000 to 21,000 RPM), which are way higher than those normally used for metals. I have been doing aluminum on our China CNC router.

Laser Cutting Machine Cut Paper

Using laser cutting machine and laser engraving machine could cut paper, paperboard such gretting card material quickly. 

OMNI laser cutting machine is cutting paper by un-touching working way, will not damage the paper surface. And OMNI laser cutting machine laser beam is with rather less size comparimg traditional cutting tool. So OMNI laser cutting machine is with rather high cutting precision, can make out fine greeting card.

When we cut paper, suggest using vacuum table on laser machine. In this way, the thin and software material could keep even for best cutting quality. If there is any question about laser cutting machine on paper cutting, kindly let me know.
