For cnc cutting machine, the cutting way is flame and plasma, no matter which cutting way we use, we can't control the cutting seam size of cutting, at the same time, we ca n 't control the accuracy of cutting out sample . CNC flame cutting machine and CNC plasma cutting machine have a common disadvantage, that is, the corner is prone to appear fuzzy "initial angle", corner cutting machine is a difficult problem.
We know that the CNC cutting system for cutting parts contour speed control and cutting process requirements are always contradictory: cutting process requirements for cutting parts contour speed, but at the same time in order to ensure the machine cutting smooth and have to slow down at each corner, accelerated operation, which will lead to a decline in cutting quality at the corner. For flame cutting, because the cutting speed is very slow, it has little effect on the cutting quality of each corner, and for plasma arc cutting, the higher the cutting speed, the worse the cutting quality of each corner, especially the thin plate cutting is more obvious, so it is more obvious to the plasma arc cutting. The numerical control system does well on the corner speed. It has detailed corner speed setting , that is, pre-processing the corner speed before cutting. The speed of the corner should be calculated according to the intersection angle of the corner line and the system parameter "centrif ugal acceleration "and the cutting speed currently set.
The quality of cutting nozzle of CNC cutting machine will affect the quality of workpiece surface and the flatness of cutting side. The method of reducing this kind of error is to select the cutting nozzle of qualified quality, and the cutting nozzle specification should also be suitable for the thickness and material of the plate that needs to be cut, which can be adjusted on the scrap first, until the width of the cutting seam is uniform, the section is flat and the slag is not hung, and then the rectangle with a fixed ruler is cut without compensation, and then the measurement is carried out, and the width of the small cut seam is compensated.https://www.wxsilvercoast.com/
