Fiber laser cutting machine has become the absolute flagship product in the metal cutting field, combined with intelligent technologies such as automatic edge finding, automatic typesetting, and leapfrogging functions, it has a broad development prospect. Nowadays, industries such as automobiles, electronics, machinery, aviation, and steel have basically completed the upgrading of traditional craftsmanship with laser processing technology, entering the era of "light manufacturing".

When the fiber laser cutting machine cuts large-format and medium-thick metal sheets in the sheet metal industry, in order to improve the utilization of the sheet and facilitate programming, the straight edge of the sheet must be parallel to the X-axis processing direction of the machine tool before laser cutting. Normally, manual calibration is used, which has low efficiency, large errors and serious material waste, which affects processing efficiency. We applied the automatic edge finding function in the fiber laser cutting machine. This function is easy to operate, high precision, and short time-consuming, which solves this problem well.

1. Introduction of automatic edge finding function

The large-format and medium-thick metal plates are placed on the closed machine tool workbench, and workers only need to press the "edge finding" button, and the equipment will calculate the inclination angle of the plate within a few seconds, and the coordinate system of the machine tool will respond accordingly. The rotation of the fiber laser cutting machine ensures that the X direction of the fiber laser cutting machine is parallel to the long and straight side of the plate.

⑴System composition

The hardware connection and composition required for the fiber laser cutting machine to realize the automatic edge finding function is shown in Figure (1), which mainly includes CNC, servo control, linear drive, sensors, etc.

⑵The principle of automatic edge finding function

As shown in Figure 2 below, when the sheet is placed on the workbench, if it is skewed, it may cause waste during cutting. If the inclination angle and origin of the sheet can be sensed, the processing procedure of the fiber laser cutting machine can be adjusted to suit the angle and position of the sheet to avoid waste. The automatic edge finding function came into being.

The automatic edge finding function is applied to the fiber laser cutting machine, which solves the problem of low material utilization in the processing of large-format and medium-thick metal plates, saves the time for calibrating the plates, effectively improves production efficiency, and provides users with This brings objective benefits and at the same time increases the degree of automation of the processing and cutting machine.
