The invention relates to a numeric control tunnel boring machine with a controlled digging and cutting cross-section shape for a test. The numeric control tunnel boring machine comprises a support machine base, a motion mechanism which is arranged on the support machine base and can move freely in the X-Y-Z directions, and a tunneling mechanism which is mounted on the motion mechanism and can move along with the motion mechanism, wherein the motion mechanism comprises an axis-X assembly, an axis-Y assembly and an axis-Z assembly which can respectively drive loaded objects to move in the X, Y and Z directions; the axis-X assembly is arranged on the support machine base; the axis-Y assembly is mounted on the axis-X assembly; the axis-Z assembly is placed on the axis-Z assembly; the tunneling mechanism comprises a ZD conversion unit, a driving assembly, a main shaft and a cutter; the ZD conversion unit is arranged on the axis-Z assembly and can move in the Z direction; the driving assembly is mounted on the ZD conversion unit; one end of the main shaft is connected with an output end of the driving assembly while the cutter is fixed at the other end of the main shaft. Compared with the prior art, the numeric control tunnel boring machine disclosed by the invention has the advantages that linkage in three directions can be carried out, so that tunnels in any shapes can be dug, thereby reducing the difficulty of tunnel model tests.
