Optimized to achieve the highest quality results at even higher speeds, the new Speedy is the fastest and most productive mid-size laser engraver in the industry. The new model produces high-quality results even at its maximum engraving speed of inches per second — which is 30 inches per second faster than the previous model.
Maximum cutting speed at highest cutting quality — this is what OptiMotion TM motion control - the new innovative Trotec path planning system- stands for. The Speedy is up to eight times faster when cutting than comparable laser machines on the market. Using OptiMotion TM the cutting speed and acceleration are calculated and optimized in real time based on the geometry.
OptiMotion TM delivers high quality in curves and maximum throughput. Tests with competitor devices have shown that cutting jobs can be completed up to eight times faster thanks to OptiMotion TM. The comparison between Trotec Speedy and two matching competitor machines is based on acceptable quality of the application. Comparing these jobs it shows that if you aim to get similar quality output, the competitor machines can not go as fast as Trotec Speedy can.
As a result only a fraction of the application is then done in the same time. It shows that Speedy with OptiMotion TM is more than 3,5 times faster than Competitor 1 and more than 8 times faster than Competitor 2 by delivering similar quality output. This measurement is important as it must be considered into the design for making tight fitting junctions while assembling multiple parts.
Experimentally we determined the a. The formula used for average kerf width is:. Average Kerf angle: The angle of the kerf channel a. The formula used for the kerf angle is:. This test required us to precisely measure the thickness of the material before and after each test with a high precision micrometer. What we show is a clear relationship between the thickness of the cut, the angle of the cut and cut depth and the laser energy.
As we increase the Energy, the conic laser beam will burn the material from the work-face towards the base in a cylindrical volume and therefore create parallel walls between the kerf. However, as the energy will be much higher, this will burn more material and therefore enlarge the overall tolerance within the cut channel. Kerf Tolerance: The Kerf tolerance seems to be fairly predictable and is related to the Energy level that we focus onto the work surface.
This is very convenient as it allows us to adjust our cut off-sets based upon the level of tolerance that we seek! Within certain limits we can predict the tolerance of the Kerf by applying a simple linear equation. However, we must be careful because, as we can see, the more energy we focus onto the cut area, the less accurate our cut becomes.
When we start to heavily melt the material within the localized region of the cut, the liquid nature of the cut zone becomes less predictable. We see that the tolerance is directly related to the power and speed. Equally, the size, focal length of the laser lens, and the users ability to precisely position the Z-height above the work surface play an important role in the accuracy of this measurement.
Within certain limits we can predict the angle of the Kerf by applying a simple linear equation. The tests done on the kerf angle are far less precise as the sample group is much smaller, and there is not enough data to verify that there is a linear relation between energy and kerf angle.
The following calculations express a linear solution for the data set that we measured. The Kerf angle is equally predictable and is related to the energy level that we focus onto the work surface.
This is perhaps generally less useful when machining parts, but there exist some very specific cases in which it is very useful. Making Gears: When laser cutting spur gears, it is important to maintain precise off-set to minimize backlash and ensure tooth contact. For spur gears, it is also important to consider the tooth profile. The tooth profile on the front surface will not be the same as the profile on the back.
This phenomenon may be totally negligible for most practical applications, but it is certainly something best understood so that considerations can be made during the design phase.
It is a multidisciplinary field at the intersection of engineering, physics, chemistry, biochemistry, nanotechnology, and biotechnology, with practical applications in the design of systems in which low volumes of fluids are processed to achieve multiplexing, automation, and high-throughput screening. Microfluidics emerged in the beginning of the s and is used in the development of inkjet printheads, DNA chips, lab-on-a-chip technology, micro-propulsion, and micro-thermal technologies.
Due to the relative scale and consistency required to manufacture a Microfluidic system, it is imperative to take into consideration the capillary geometry as it will have an impact on the performance of the system.
One must take into consideration the cross section of the capillary, of which the two principal dimensions will be depth and taper see figure. The proposed calculations for taper angle may allow for the development of more precise microfluidic systems.
Cut depth The cut depth is very predictable and is related to the energy level that we focus onto the work surface. This is interesting as it allows us to adjust our engraving depth as well as our cutting parameters for varying thickness of PMMA. The tests were all done at relatively low energy levels as we wanted to reduce the impact of smoke. Tests at higher power are less precise as we have a high concentration of smoke that stays within the channel, as well as the refraction of the laser against the non-parallel kerf walls.
