The utility model discloses a shield constructs cutter cutting force and changes testing arrangement and system, the device includes: frame, experiment piece fixed knot construct for the experiment piece of fixed cutting, two hydraulic jack and PRESSURE DETECTOR. The utility model provides a shield constructs cutter cutting force and changes testing arrangement and system, through setting up two hydraulic jack, make the cutter move on the face that the flexible direction of these two hydraulic jack formed, when one of them hydraulic jack during operation, the cutter can the linear interpolation, when two hydraulic jack during operations, the arc cutting can be realized to the cutter, thereby make should test the cutter not only can linear -cutting, can also arc or the cutting of other unshaped, thereby greatly increased the investigation factor of cutter, can accomplish the optimalizing tool clearance of cutter cutting force, the anterior angle, the investigation of various factorss such as chasing speed.
