After triggering, this function interface will be presented in the form of a pop-up window. Step 2: In the human-computer interaction interface, establish two mutually perpendicular number axes with a common origin to form a rectangular coordinate system of X and Y axes. The coordinate axes provide scales. Within the X and Y coordinate areas, rasterization is performed with the scales as the resolution. A raster map is established to divide the roadway cross-section to be cut. The X and Y coordinate scale data are automatically generated from the preset cross-section size data. The minimum resolution of the raster is the preset cutting head radius size. Step 3: According to the cutting process specifications provided by the mine, including the cutting cross-section size and cutting process path, click at the intersection of the X and Y axes or the midpoint of the unit grid within the rasterized map area to select the starting and ending points of each segment of the cutting trajectory and generate inflection point coordinate data. After each cutting trajectory is completed, the rasterized map will automatically generate a line connecting the coordinates of the two points, and select the coordinates of the inflection point of the next cutting trajectory until the planning of all cutting process paths is completed and coordinate lines are generated. At the same time, the data is numbered and packaged, and sent to the lower computer execution controller through the network communication protocol to drive the cutting unit to perform cutting and tunneling operations. During the point selection process, the human-computer interaction interface has an automatic grid intersection optimization control strategy to identify and judge the point selection coordinate data. That is, the manual point selection coordinate data is identified and judged by the intersection points of the roadway boundary and the adjacent X and Y axis grids, and the matching control algorithm optimizes the trajectory coordinate data of the point selection.
