A common application for laser tools is in cutting and engraving wood. Plywood, MDF, soft or hard wood, as well as numerous other types of wood can be engraved using laser cutting tools. It’s a quick and effective method of creating professional quality wooden items, that is widely used by fabricators. Lasers are used for cutting and engraving wood because they leave a high quality clean finish and because of their ease of use. Laser engravers are used in conjunction with graphics programs. These allow a design to be created digitally first then sent to the cutting machine for production. Lasers also allow for very precise geometries to be engraved. To engrave at...
There are many different techniques that can be utilised when laser cutting. In order to ensure materials are cut to a high standard it may be necessary to make use of various methods to see which works effectively. When cutting with a CNC laser, a common technique is to move the cutting head over the metal plate in the shape of the desired part. This allows the part to be cut cleanly out of the pate in one piece. A capacitive height contol system can also be used, this will maintain a very accurate distance between the end of the laser nozzle and the plate that is being cut. Maintaining a precise...
Lazer cutting is a manufacturing process which is used commonly on engineering, production and fabrication jobs. The process can eliminate the need for machining on many different jobs, allowing faster production times and a more efficient manufacturing process overall. Lazer cutting is often compared to plasma cutting as they are relatively similar processes, however lazer cutting offers several advantages. For instance lazer cutting is more precise and uses less energy when cutting durable materials such as steel and aluminium sheets. Lazer cutting is also becoming more advanced, offering the ability to cut through ever more thicker materials. The precision and quality of cut that can be achieved with a lazer is of...
Many manufacturers chose acrylic as a primary material when producing plastic goods. This is due in part to the low cost associated with both the material and the cutting required. It’s also considered an attractive material, it has a glossy surface and comes in a variety of thicknesses and colours. The edges of laser-cut acrylic have a laser-polished look which is seen as a professional standard. When produced professionally acrylic usually comes with a paper masking on both sides. Using acrylic does have some downsides however. It is somewhat brittle, so the person handling the material needs to be careful not to drop it. A heavy drop on the corner of an acrylic...
When laser cutting, its important to understand the settings and functions of the cutter before anything has been permanently cut into. This can be done in a variety of ways, using presets is one method of setting up your cutter before hand. Your laser should have some suggested settings for cutting or engraving different materials and different thicknesses. You should also be able to load these settings into your computer or laser and save them as presets. Be sure to name them something that makes sense so you can easily find them again. Test cuts are also used to set up a cutter before hand. This can be done by creating...
