a2: the horizontal position relation between the cutter measuring head (101) and the cutter is adjusted through the front-back moving mechanism (3);
a3: the vertical position relation between the cutter measuring head (101) and the cutter is adjusted through the spiral lifting mechanism (2);
a4: the measuring end part of the cutter measuring head (101) is aligned to the direction of the cutter fixing device, and the tool setting movement amount of the cutter is transmitted to the measuring rod (102);
a5: the movement amount is transmitted to the flat measuring head (103) through the measuring rod (102), the flat measuring head (103) is driven to move when the measuring rod (102) moves, and the movement amount of the cutter measuring head (101) is fed back to the first mechanical meter.
