according to fig. 1-8, the path of movement of the support base 3, and therefore of the knives on the cutterhead 5, is first set by conventional programming;
in the programming process, the moving distance of the supporting base 3 is prolonged during transposition, and then in the moving process of the supporting base 3, automatic transposition is carried out through the following processes:
when the position needs to be changed, the cutter is gradually separated from the object, and the moving distance of the supporting base 3 is prolonged during the position changing, so that the supporting base 3 can gradually move towards the limiting block 2, and the limiting block 2 extrudes the connecting rod 11;
when the connecting rod 11 is pressed, the supporting disk 10 is synchronously pressed, so that the supporting disk 10 and the cutter head 5 are close to each other, the supporting rod 14 extends into the sleeve 12, and the spring 13 is compressed;
while the supporting disc 10 and the cutter disc 5 are close to each other, the twist threaded rod 15 gradually approaches the twist threaded hole 16 until the twist threaded rod contacts the twist threaded hole;
in the process that the twist threaded rod 15 gradually approaches the twist threaded hole 16 to be contacted, the positioning tooth block 9 also moves towards the inside of the cutter head 5, so that the limit teeth 8 and the teeth on the positioning tooth block 9 are completely staggered, and the connection between the limit teeth and the positioning tooth block is disconnected;
then, the supporting disk 10 and the cutter head 5 are continuously close to each other, the twisted threaded rod 15 can be in threaded connection with the twisted threaded hole 16 under the action of the torsion spring 18, and the rotating shaft 17 provided with the twisted threaded hole 16 can rotate through the threaded connection of the twisted threaded rod and the twisted threaded hole;
