Cardboard Innovation Using CNC Laser Machines

For a machine that is capable of cutting metal or non-metal plates such as stainless steel or carbon steel the process of cutting cardboard or making holes or pattern cutting on cardboard is a very simple task. What needs to be observed is the finish imparted to the cutting edge of the cardboard. The versatile machine that can do this task is the OMNI CNC Metal and Non-Metal Laser Cutting machine.

Check out the video (,) that shows off the impressive ability to drill holes in cardboard with such accuracy that is beyond comprehension. The responsible element in the machine is 130 watt (also available as 150W) sealed CO2 (carbon dioxide) laser that commands an accuracy of plus or minus one-twentieth of a millimeter.

Laser cutting by CNC machine involves motion control system of the lasing device to follow G-code of the tool path. The lasing beam is focused at the material (in the video it is cardboard) that vaporizes away the cardboard leaving behind a high quality edged finish.

CNC Laser Machines

CO2 lasers are used in industrial cutting for prototyping packaging material which allows quick sampling before final production. As an example the use of lasers in the manufacture of advertising display modules has greatly revolutionized display elements in brick and mortar establishments. CO2 lasers can cut through several materials which include aluminum, stainless steel, wood, plywood, cardboard, plastics and fabrics.

The OMNI CNC laser machine is available in two models – We also offer OMNI

•  The OMNI 1390 andThe OMNI 1325 model.

Both of these models have a working speed of 600 mm per secondand are equipped with protective systems as well as water cooling equipment. Laser cut edges are crisp and the results can be stunning as can be seen in this origami patter on cardboard. Today cardboard furniture is witnessing innovation in design as can be seen in these samples.

3D Technology in Overdrive

Technology advancement has led CNC router applications unprecedented range in the use of designs, material and scope. 3d printing is an extension of 3d CNC router application and the future looks promising.

What is 3d Carving by CNC?

To understand 3d carving a little background in 2d is necessary. Cutting a flat outline in a straight up and down motion by the cutter can be constituted as 2d – short for two dimension. Like length and width or breadth and width. If you take this understanding a bit further by assigning the depth of cut to vary then you have a horizontal cut, a vertical mill or cut and a varying amount of depth. This is classified as 2.5d – two and half dimension. The reason why the fraction of a dimension came into being was that CNC industry was aware that complete 3d – three dimensional was just one step away. Other media such as films and optical glasses had already entered the mainstream and carving 3d was a foregone conclusion. In 2.5d it was just a case of extending the cutter to work in an up and down movement.

What Differentiates 3d from 2,5d?

2.5d CAD / CAM software works at cutting out the material say wood or plastics and removing material from the cut areas (called pocketing). The pocketing was made to look hand carved with the use of v-carving bits that gave a great look to lettering or signage. The process was fairly quick as there was no need for visualization.

3d carving however needed visualization. It was imagining a hologram image of the object but on the CAD/CAM software. It was 3d rendering of converting 3d wire frame models into 2d images. To explain in simple terms every point of a 3d model was plotted and this included the depth points as well. Extrapolating Euclidean geometry did the trick of visualization. This geometry also explains how pattern making for prototyping has led to advances in 3d printing.

How is 3d CNC Router Used in Interior Decoration?

Man is very creative; with 3d CNC routing it was to give Man an inch and he did not stop at that he went for the whole mile. CNC wood routers spin at nearly 24000 rpm (revolutions per minute) with the spindle varying in power from 5 to 15 horsepower. This gives the CNC Router (example of OMNI CNC 1328 model) to machine hundreds of inches in a minute. Carving pictures and design in wood has become so easy that there is no aspect of interior decoration that cannot be carved. Some examples include

• Table legs for armoires, coffee tables, dining tables, chair legs, bedposts
• Cornices and modillions for mantel pieces, kitchen islands, fireplaces, window embellishments
• Kitchen cabinets, doors, handles,
• Wardrobe carvings, Main door relief sculptures
• Partitions, panel designs
• Ceiling designs, wall designs

The list is endless. CNC routers went another step further by making heavy duty routers and carbide tipped bits that treat stone as if it were wood and lo and behold 3d carving in stone became the next big thing. Stone pillars, cornices, signs, company names. Tombstones were just another matter irrespective of whether the material was granite, marble, soapstone or any other stone material. This YouTube video is self-explanatory.

CNC Routers Machining Tomorrows Engineering

CNC machining, mold making or turning out components require basic knowledge of geometry. This is a simple guide to the basics of high school geometry. Of course our forefathers never went to high school but still learnt the basics via common sense.

Take a long thin and flat piece of wood or foam or any material that can be cast. Let the object be 1cm wide, 2mm thick and 15cm long. Lay the object on its side and try to break it. There will be resistance as the object flexes. Now lay the object on its 2mm thick edge. Apply the same force from the other side and try to break it. The long object will resist forces and will also not flex. Although the cross section is still the same it exhibits greater resistance to forces. This is the principal used in designing any part particularly plastic parts for improving rigidity by increasing the maximum span of the object in the same direction that is subject to bending force. The engineering trick is to add ribs – example ‘C’ sections, ‘U’ sections or ‘F” sections.

CNC Routers Machining

Robotic engineering makes use of rib engineering as it allows very thin chassis to maintain rigidity. The ribs are routed in such a manner that areas requiring additional clearance are factored in the mechanical design.

Robotic Engineering Design

Mold designs use the principle of reinforcing sharp corners and holes that are subjected to forces and stresses. Simple reinforcement ensures that stress is distributed. CNC routers can simplify the designs when using foam as the router follows the tool path to produce ribs as delicate as 100 microns (twice the width of human hair). The CNC router is an indispensable machine tool that can tackle large mold designs (such as blades for windmills) or as small as the drones that are slated to carry 1 kg packages for Amazon delivery services. Recently Elon Musk OD SpaceX identified that the ribs supporting the landing fins of the Falcon booster rocket buckled because of faulty reinforcing design of the rib. The simple act of strengthening the rib allowed the Falcon booster stages to land perfectly in the vertical position. This was tested by CNC machining.

CNC Machining For Countertop Production

Countertops are created from several types of stones. The most common stone in use is Granite. Marble is also a preferred material. To achieve a perfectly positioned countertop involves several factors.

• Cutouts for the sink
• Seams to appear seamless
• Cabinet positioning for proper placement of granite / stone slab

Stone is heavy and proper supports are needed as the countertop needs to last a longtime; probably a lifetime. The alignment and cutting the openings of the sink is a critical element in the function as well as the decor of the kitchen. Finally is the edging finish to the countertop. There are several edging finishes such as

• Half round
• Fully rounded
• Half round with bottom beveling
• Fully beveled

Creative Stone Countertops Pawtucket

Presently a digital template of the countertop is produced as a computer file ensuring that measurements are accurate. The advantage of digital templating by laser ensures that accuracy is achieved due to the precision involved in digital measurements. This also prevents human errors. On the computer screen, the image of the stone slab is over-layed with the image of the digital template and everything is checked once again.

The stone slab is mounted on the worktable of the OMNI CNC 1325, which is a versatile CNC router for stone routing operations. CNC machining by this robust state of the art stone router is precision combined with speed. The stone slab is cut as per the image and edged; Cutout pieces for under mount sink and holes for faucets are drilled. The reason for precision measurements taken earlier become clear as the under-mount sinks match perfectly and the half-round edging under the sink allows perfect fitting. Polishing the back side of the coarse stone slab as well as the underside of the overhang gives a smooth feeling when felt. To make the seams as seamless as possible the CNC machine uses polishing tools to make the surfaces of the joints smooth.

Quartz Engineered Stone Countertops

Countertops are manufactured from 2 cm and 3 cm quartz, or granite or engineered marble stones. Mitered saw edging is possible as the heavy-duty spindle is capable of performing profiling and machining with ease. Employing a higher rated spindle allows greater torque at lower rpm (revolutions per minute). This gives the added facility of honing, brushing and texturing of different stones.

OMNI-CNC Routers are equipped with NC Studio control system or DSP handle controller or Syntec PC platform. Capable of spindle speeds of 24,000 rpm the CNC machine is equipped with water cooling system that is ideally suited for countertop production. High degree of tolerance of plus or minus 0.05 mm (millimeter) for a machine that works with heavy stone material is achieved because of a robustly built frame that is reinforced by ultra-thick steel tubes with welds that are quenched. To facilitate the easy movement of the stone slabs the machine table is equipped with a coolant tray with wheels.

CNC Routers are Ideal for Puzzle Manufacturing

Puzzle manufacturing has undergone several iteration over the years; Similar to changes in technology, engineering a puzzle in the present 21st Century is completely different from methods employed in 1760 by John Spilbury (a cartographer – meaning a person who made hand drawn maps) when probably the first puzzles were created. John Spilbury pasted his maps on thin pieces of cedar panels and cut them using a marquetry saw. Marquetry is the tool derived from the ancient art of inlay where a solid piece of material is cut out so as to receive another material to form a surface patterned finish.

Puzzle Manufacturing CNC Routers

Spilbury’s maps soon became popular and the art of puzzle making by the jigsaw (marquetry tool) method became widespread; with advances due to the Industrial revolution and new printing technologies the offset printed pictures soon found their way and glued onto cardboard as well wooden veneers and die-cut in various shapes. The market for puzzles reached its peak during World War 2 and thereafter as Jackson Pollock’s painting Convergence became a best-selling puzzle and enjoyed by thousands of Americans. Wooden puzzles are making a comeback after all these years primarily for affordable CNC laser routers that have allowed small custom wooden puzzle manufacturers to reinvent the art. Lasers can cut with precision, as it is a concentrated beam of light that does the cutting. The beam is very thin and the cut is also clean leaving no burrs. The term jigsaw puzzle is apt for laser cut puzzles as intricate shapes can dovetail into each other when finally assembled.

Sign making CNC routers

Sign making CNC routers such as the OMNI CNC 1318 model is also capable of puzzle cutting as well as 3 dimensional character cutting. A powerful spindle operating at 24000 rpm rated at 1.5kw and protected with digital spindle temperature monitor is the perfect tool for craftsmen to produce wooden based puzzles. The advantage of the vacuum combined T-slot enables proper material hold down and the linear guide on 3 axis is the perfect traverse system that can work 24 x 7. OMNI-CNC Routers are based in China and among the top suppliers of affordable CNC routers.

Requiem for the Departed to Live Forever Via Tombstone Engraving By CNC Router

Benjamin Franklin wrote in 1789 after the Constitution of America was established describing it as an appearance that promised permanency but in this world there are only two things that are permanent death and taxes.

Tombstone Engraving by CNC router

This blog is more about perpetuating death and less about taxes. Most people like to be remembered – by the people who are alive want to remember the dead and so it became perhaps one of the earliest professions of a tombstone engraver and the engraver’s place of work was the cemetery. Even today, it is common for a stone-mason and his assistant busy chipping names and dates on granite stones (if the people are middle class) and marble (if the people are wealthy). It is also normal for the stonemason to be replaced by a small workshop equipped with a stone engraving CNC router machine. Both the manual and machine coexist.

In the video clip ( the CNC router is quickly finishing the cross on the headstone of a tombstone. The speed of the router is amazing. Laser etching CNC machines are also employed for tombstone engraving. This is an expensive method and only the wealthy can afford the laser etching. However, for a tombstone accuracy is not really required and speed is not a constraint for the departed. The router in the video clip is made by OMNI CNC, which is a reputed CNC router manufacturer from China. The stone CNC router is specially built with heavy duty frame work and solid rib welding that houses the high power spindle and advanced control system.

Stone CNC Router

The table is also rigidly built and the heavy-duty construction allows different kinds of tombstones such as granite, marble, soapstone and other natural materials for engraving. THhe design input takes text and other designs such as the Catholic cross and the G-coded technology makes short work of the engraving in no time. The process is very fast and accurate.

Vectoring and Rastering via CNC Lasering

OMNI CNC are true technology partners to Signage industry entrepreneurs as they manufacture specialty laser machines that aids creativity in design and increased productivity.

The role of CNC Router manufacturers does not end just churning out machine after machine. Unless and until these manufacturers work as a silent but adjunct partner of the industry to which they are supplying the machine then only they can earn the badge of success. The CNC Router marketplace is intensively competitive. Manufacturers from America, Europe, and United Kingdom being pioneers have an inherent edge. China is the new powerhouse of CNC Router manufacturing. There are many manufacturers. One among them is making waves. This company is OMNI CNC Router manufacturers. They have passion for understanding to which they are supplying.

As an example, they supplied OMNI CNC Laser machine to FRF from Budapest in Europe. John Baksai the owner of FRF is another passionate and dedicated artisan who has created a niche in advertising display by specializing in light boxes, lighting and non-lighting display signage, LED advertising signage and other display production items like totem poles and neon tube manufacturing among others.

Vectoring and Rastering

Being a design-oriented company the accuracy of cutting LED signage as per original designs conceptualized becomes important in achieving the quality. FRF incorporate high quality standards in the materials like electronic equipment, LED light sources and enclosures in the designing and manufacture of LED advertising signage. The accuracy of design matching the concepts has taken FRF LED lighting signage to Romania, Austria, Belgium and Germany in Europe and to Hong Kong in China and Seoul in South Korea.

Vectoring and Rastering

OMNI CNC Routers with Laser cutting systems employ cutting-edge technology in vector cutting and raster engraving. Vector paths are clear defining tool paths for the CNC Router bits to accurately cut acrylic or other translucent material used in signage. The OMNI CNC laser machine performs vector cutting and raster engraving. Vector cutting is the process of cutting the outline shape of the image while raster engraving performs engraving functions as the tool bit glides along the substrate. The advantage of laser cutting is it can be used on several substrates. Vector means a line that allows designing LED lighting shapes as per image. There is calculation of geometry and other mathematical formula in computing the type of cutting.

Raster cutting is similar to printer simulation. The tool head of the Router moves back and forth creating pixilation of bit-maps Raster images are denoted in dpi (dots per inch). Incorporating a combination of vector imaging with raster graphics is the hallmark of FRF in Budapest that are faithfully executed by OMNI CNC Router Laser machine. The substrates like acrylic, leather, wood (MDF, plywood, soft woods) and other plastics like ABS, Polycarbonate, and Plastic Foam can all be cut using OMNI CNC Laser machine by vectoring.

Turning Hobbies to Business Idea with CNC Woodworking Routers

Prime examples of using CNC woodworking routers to turn a hobby of toy carving into a profitable business

Before electronics or electrons became a part of the mystique of civilization Man was using wood for building houses, as fuel for cooking and ultimately toys for children to play. So much so the carpentry world had its first taste of entrepreneurship in toy manufacturing as whittling became an art form. Carving intricate shapes in wood stemmed from carving basic shapes using a pocket knife. This led to the discovery of soft woods and the simple act of whittling turned into toy carving of dolls and figure and thereafter woodworking toys became a major industry. Read more
