Lasers: Cut and Engrave
This is useful for cutting holes in plastic enclosures such as those from www. The Verslaser acts like a printer, so any vector graphic that you draw can be 'printed' onto a surface, either etched or cut through. The easiest way to make a pattern is to use Visio from Microsoft. At this point your drawing is ready to be "burned". Put it on a USB drive, and contact Mr. Bring the material that you wish to use or use the department-provided supply -- it is good to have extra material in case something goes wrong. You should also bring some heavy stock paper if you want to 'test' the cutting before you try cutting the real material. Do not put multiple drawing sheets in the same file; instead, use a separate file for each drawing sheet. Do not use 'raster' images in your drawing - everything should be a line drawing. The ECE department has some Acrylic sheets available for each team. If the Senior Design team should need more than what is provided by the ECE department, the material will have to be procured by the team. Maker Case - Web-based application for laying out project boxes. Very handy application. Inkscape - Vector graphics program. Freeware and available for Windows, Mac and Linux. This program is good because it will produce SVG files and import directly into Visio. Microsoft Visio - Visio is the primary software used with the laser cutter. You should now be on the Microsoft Dreamspark page and see the available software. Click on the Visio orlink and click Add to Cart. Search this site. Versa Laser Cutter. To prepare a drawing, do the following in Visio: Create a new drawing in US units. You will probably want to have fixed grid for your drawing. Here are some samples: sample1sample2. For now, your page size can be anything -- it will have to be changed once your file is loaded into Visio on the computer running the laser cutter. The maximum material size handled by the laser cutter is 12" x 24". Any other lines that you need for reference, make them either blue or black these will be skipped during the laser burn. The best way to draw geometry is to make the dimensions relative to some border that you draw. It is very difficult to have the laser go to an absolute location due to imprecise placement of the material inside the Versa laser cutter, but the laser is very precise in relative movements. If you must have absolute coordinates: the lower left-hand corner of the page is the lower left hand corner of the laser 'burn' area, so reference everything from there. The laser cutter has a X,Y offset of The easiest way to do this is to first draw all of your vectors normally referencing the lower-left hand corner as 0,0.

If you are not aware of the compoistion of the material, try the Beilstein test to avoid highly toxic chloro-dioxins : A copper wire is cleaned and heated in a Bunsen burner flame to form a coating of copper oxide. It is then dipped in the sample to be tested and once again heated in a flame. A positive test is indicated by a green flame caused by the formation of a copper halide. On the PC machine driving the lasercutter, in the Imal main folder, there is a folder ' LaserCutter Templates ' with ready-made settings. You will also find near the laser cutter a few test sheets of cardboard, mdf and plexiglass with cuts at various powers and speed and the corresponding values thanks to Julien and Hans. Finally, you can also find some settings and tips below. For thin cardboard, hold the sheet down with something heavy around the cutting area to maintain it perfectly flat. If you do a cutout around the whole object, make sure the cutout happens at the end. Because of the material, the cutout can move the cardboard, causing imprecisions. You can change the order by putting the cutout on a separate layer with a higher number so if your object is on layer 1, put the cutout on layer 2. Make sure the speed settings of both layers are correct. MDF is engineered wood, wood fibers held together by wax and resin. This is why your MDF might appear to "sweat" when cut, ending up a bit sticky and making the blades dirty. Formaldehyde resin, often used in MDF, isn't cool. So don't oversniff it because "it's just wood". It's not. Different brands and colors have different resistence to the laser beam, so always test the settings before cutting big parts. Glass can only be engraved. After engraving, you MUST run a scrubber sponge on the surface to remove the micro-shards the laser created in the glass. Back of mirror can be etched very easly with S20 pw 10 to be confirmed. Please note: This is only an indication, you should ALWAYS make tests and ALWAYS look after your material while it's being cut especially considered the machine calibration was changed since our first tests The focal length - the distance between the noze tip and your material - is 6mm. You will also find near the laser cutter a few test sheets of cardboard, mdf and plexiglass with cuts at various powers and speed and the corresponding values thanks to Julien and Hans Finally, you can also find some settings and tips below. Cardboard For thin cardboard, hold the sheet down with something heavy around the cutting area to maintain it perfectly flat. Use cast acrylic. It certainly seems to happen with plexiglas. According to what I have read on CNC Zone, lifting the material off the cutting bed for example with pieces of wood at every corner should help. To be tested and tried. Dirty blades especially from MDF glue also make those marks more likely. Tags lasercutter plexiglas pmma wood. Links cutlasercut. Admin Login.

Parts could be scrapped because of inconsistent cut quality, or assist gas could be wasted because of leaks in the gas delivery system. For some, laser maintenance is a given. The meticulous metal fabricator knows how important it is to keep the laser cutting machine at its top efficiency and productivity levels. The equipment is probably under a service contract, and the fabricator religiously follows scheduled preventive maintenance recommendations. For others, laser maintenance is out of sight and out of mind see Figure 1. These carefree fabricators are more concerned with uptime than scheduling downtime for maintenance. But at this point, because the fabricator has not stayed on top of recommended maintenance activities, the equipment operator is at a loss where to begin the investigation. The problem can be due to any number of variables, and precious productive cutting time is lost while the search for the cause of the production disruption takes place. No matter what the approach to laser maintenance may be, a metal fabricator can reduce future hassles significantly by staying mindful of just a few commonly overlooked maintenance areas. Otherwise, out-of-spec optics can affect mode quality, beam quality, cutting performance, and optics life. Beam analyzer and beam profilers are available to address this issue. These tools are large camera-based systems that measure the beam characteristics when the laser beam passes through. However, this equipment is typically very expensive to purchase and complicated to use in a shop environment. Because the beam must pass through the large analyzer box, it needs to be placed on the machine table, underneath the Z axis, a tight spot. Some manufacturers eliminate the need for that costly equipment by imprinting and attaching original mode burn profiles on a piece of acrylic attached to each machine before it leaves the factory. This allows fabricators to reference and check quickly for proper shape, size, power setting, and beam optic specifications. As the fabricator checks out the resonator and the beam delivery components, he or she is looking for cleanliness. If spots on an optic are ingrained onto the surface, meaning they cannot be wiped away, they will continue to grow and will need to be replaced. At the processing area, the operator checks primarily the processing lens, but also confirms that all optical components throughout the system are aligned. Hot and cold optics checks can be performed both at the resonator and at the processing area. Hot burns most often affect the transmissive optics—or those that absorb heat—specifically the output coupler and lens. If any optics are causing thermal distortion, the evidence reveals itself immediately. Kerf change is easily seen in mild steel, medium sheet cutting with oxygen. If this is the case, the operator is able to isolate and identify the culprit: output coupler or lens. Most laser machines use an assist gas for cutting. Assist gas flows through the laser head and out the cutting nozzle with the laser beam to achieve a cleaner cut. Oxygen, nitrogen, and shop air are the most common assist gases. Oxygen requires the lowest flow, but leaves oxidized edges on the part after the cut. Nitrogen usage requires greater pressure to deliver it to the cutting head, but it also results in a clean, precise cut without oxidation. Shop air is the fastest-processing assist gas and is widely used for cutting stainless steel, mild steel, and aluminum sheet metals. Most compressor OEMs issue recommended maintenance guidelines, but a monthly check is standard. Contamination of the air source affects cutting performance, machine life, and productivity. Figure 2: Dirty slats are not only unsightly, but also ill-advised. The buildup of material on the slats can prevent material from lying flat during the cutting, which can affect cut quality, and can cause excessive damage to the material surface. Fabricators also should have a dedicated compressor for the laser cutting machine to support the assist gas supply. This prevents downstream processes from using the same air source and decreasing air pressure to the machine. Nitrogen generators as a source of assist gas are growing in popularity. This process feeds compressed air into a membrane that purifies the air into nitrogen, which is then used as the assist gas. The chiller needs to be looked at.
