The application discloses a space network networking method and device, a network resource arrangement platform and a storage medium. The method comprises the following steps: in the case that a UAV service accesses a network, the position of the UAV performing the UAV service is determined; the service score corresponding to the cell within the preset distance range from the position of the UAV is determined; the preset number of cells with the highest service score are determined as the space candidate working cells, and the number of adjustable beams of the space candidate working cells is determined; and the space-to-air beam and the ground-to-air beam of the space candidate working cells are determined and set according to the number of adjustable beams. The application solves the technical problems that the UAV space coverage scheme in the related art mostly needs to add equipment for transmission transformation, the cost is too high, the scheme of covering the space by directly using the existing site resources has too great influence on the ground coverage, and the beam resources for covering the space are wasted.

This invention relates to the field of five-axis machining technology and discloses a method for measuring the Z-axis value of the workpiece coordinate system origin and the tool length. The method involves placing the Z-axis setter on the upper surface of the workpiece; with the spindle stopped, lifting the handwheel pulse generator and gently pressing the spindle end face against the elastic upper plane of the Z-axis setter; adjusting the movement ratio of the handwheel pulse generator to "X1"; moving the spindle away from the Z-axis setter; mounting the tool on the spindle; adjusting the movement ratio of the handwheel pulse generator to "X1" again, and the pointer of the Z-axis setter pointing to the "0" mark; due to the addition of the Z-axis setter, the Z-axis value h0 of point B in the workpiece coordinate system in the machine tool coordinate system A is -h - h1 - 50, where 50 is the fixed height of the Z-axis setter. This method ultimately yields the Z-axis value of the workpiece coordinate system origin. This method reduces the cost for companies to purchase on-machine measuring instruments and tool pre-setting devices, achieving high operation speed, high efficiency, high precision, and excellent cost-effectiveness.
