Inspection of our work area¶
Safety¶
Before you start with everything do not forget to be with the corresponding PPE, for the case of laser cutting, which are: HALF FACE RESPIRATOR, EAR PLUGS, LASER PROTECTION GLASSES AND SAFETY GLOVES. It may seem uncomfortable, but it is better to be well protected.
Switch-on sequence¶
Here we are, in our work area, we have: 1. Voltage regulator. 2. Chiller liquid cooler. 3. Laser Cutting Equipment GCC X500III. 4. PURE AIR air purifying filter.
We proceed to turn on all the equipment according to the list: 1, 2, 3 and 4. In order not to have inconveniences or failures, to turn off all the equipment is in reverse, that is, 4, 3, 2 and 1, respectively.
1. VOLTAGE REGULATOR¶
2. CHILLER COOLING SYSTEM¶
3. GCC LASER POWER SWITCH¶
4. PURE AIR SYSTEM.¶
DESIGN & CUT¶
For the laser cutting and engraving process, we will choose to work with COREL DRAW software, since it allows us to work with vectors, ideal to indicate to the equipment which lines and powers to apply in this step.
Once the design stage is finished, we will select the equipment installed in our laboratory, to define the most important parameters, such as: cutting speed, power and PPI.
These are very important to have good quality in cutting and engraving, as we also help to extend the life of our equipment.
Once all the parameters have been defined, we simply hit print, that’s where the magic happens.
Before we can cut we have to adjust the focal distance, so that the cuts and engravings are precise and we do not have problems when removing the cut material from the cutting table.
According to the sample provided in the photograph: Material thickness = focal length.
Let’s observe the team working on the 5.5 mm thick MDF material, the parameters are also plotted on the material to be recorded.
After the cleaning generated by the cut, this is how it looks like.
Now with the cutting table as an example, we have a gauge that will help us in making measurements and tolerances for a better cut in socket parts.
We design lace pieces for a sample pixel wall, these in union with others can generate interesting 3D images. so let’s see.
We cut according to parameters
We assemble our cut pieces and have a structure.
VINYL CUTTING¶
Well, now this process is similar to laser cutting, because we work with vectors, and we change some parameters like: FORCE and SPEED. On the vinyl, which is a material that adheres to almost any surface, except rough or textrurized surfaces. Then, we will make a printing process with textile vinyl, let’s go!
We load our textile vinyl to the cutting area, calibrate ends and fix.
