The TPT cutting lay up device has a relatively high cutting accuracy, a relatively high speed, and is not limited by a cutting pattern, and has a low cost when processed. TPT cutting devices are gradually replacing traditional metal cutting process equipment. In addition, the application range of the TPT cutting device is becoming wider and wider, and the cutting accuracy of the laser cutting machine is related to the processing technology to a great extent.
For the understanding of the cutting accuracy on the TPT cutting lay up device, there are many misunderstandings for more people. In fact, the cutting accuracy of the cutting device does not depend entirely on the device itself, and it is affected to a large extent by various factors. One of them is also the impact of cutting speed.
The speed of the TPT cutting device when cutting is to increase the quality of the cut. After that, it is necessary to pay attention to improving the quality of the cut. After the cut is slightly narrowed, the surface of the cut is evener, and the occurrence of deformation can also be reduced. . If the cutting speed is too fast, the cutting line energy will be lower than the required amount. The jet in the slit cannot quickly blow the melted cutting melt off immediately to form a relatively large amount of rear drag, accompanied by slag, nicks, and incisions. The surface quality will also drop.
The TPT cutting lay up device is in use when the cutting speed is too low, because the cutting point is the anode of the plasma arc. In order to maintain the stability of the arc itself, the anode spot or the anode region must be near the nearest cutting slit to the arc. Finding the place where the current is conducted will at the same time transmit more heat to the radial direction of the jet.
Therefore, when the TPT cutting lay up device is actually used, the incision will be widened, and the materials melted on both sides of the incision will gather at the bottom edge and solidify to form slag which is not easy to be cleaned, and the upper edge of the incision will melt too much due to heating. Rounded corners. When the speed on the TPT cutting device is relatively low, the arc may even extinguish because the slit is too wide. Therefore, it is inseparable with its good cutting quality and cutting speed.
