Factors and control skills of CNC cutting machine cutting trajectory change?

Usually, the finished cutting graphics we see are the cutting graphics set by the CNC cutting machine before cutting, which is a continuous cutting operation according to the cutting trajectory.

However, in practical applications, various factors such as the shape of the steel plate, the size of the parts, and the thickness and material must be taken into account to determine where to start cutting when the knife is moved.

The so-called cutting distance is simply understood as the height of the cutting torch and the cutting surface. The cutting distance is mainly affected by factors such as cutting material, cutting thickness and cutting fuel. When adjusting the cutting distance, you can visually control it according to the requirements of the instruction manual. Of course, the configuration of the cutting machine can also be improved from the hardware, such as adding an automatic adjustment device to achieve the effect of automatically adjusting the cutting distance.

In general, when using plasma cutting perforation, the initial arc starting distance should be twice the normal cutting distance or the maximum height that the plasma arc can transmit.

In general, when using a CNC cutting machine, we recommend that the user design the position of the cutting point at the edge of the steel plate. Considering the preheating problem of flame cutting, the above description will mainly focus on plasma cutting, try not to use the "pierce cutting" method, the main reason is that using the edge as the starting point will prolong the life of wearing parts. The correct method is to aim the nozzle directly at the edge of the workpiece before starting the plasma arc.

Of course, in order to improve the quality of the cutting surface of the part, when using edge cutting, it is recommended to add a lead wire of an appropriate length to improve the quality of the cutting seam.
