A cutting machine for cutting a flat workpiece comprises a cutting table having a working surface for supporting the flat workpiece, a support movable parallel to the working surface, and a cutting unit mounted on the support above the working surface, the cutting unit comprising a cutting knife vertically adjustable relative to the working surface to regulate the cutting depth of the knife, a vertically displaceable carriage for the cutting knife for vertically adjusting the knife, a cutting knife holder rotatable about a vertical axis for orienting the knife in a desired direction, and drives actuatable for displacing the carriage, rotating the holder and moving the support in response to a programmable control. To engage the position of the cutting knife to be efficiently adjusted, a setting device is provided, the setting device comprising a vertically extending positioning path indicator arranged to indicate the actual position of the cutting knife in a set position and to transmit to the control a signal corresponding to a deviation of the actual position from a pre-set vertical position of the indicator relative to the working surface whereby a reference point for the vertical adjustment of the cutting knife is put in the control.
