A vehicle-mount-type building-materials process system and a building-materials processing method

Provided is an in-vehicle building material processing system that enables a non-skilled worker to easily perform cutting at a construction site other than a factory， without giving rise to the problem of a cutting means contacting a clamper and damaging both. The in-vehicle building material processing system is provided with: a flat carrier (60) formed in a vehicle (90); a rigid member that ensures a flatness degree with respect to a workpiece receiving base (50) formed in a prescribed section of the flat carrier (60); clampers (11 to 18) that fix a building material to the workpiece receiving base (50); an articulated robot (40) that is fitted at a tip end thereof with a swingable cutting means (30) capable of swinging outside the periphery (51 to 54) of the workpiece receiving base (50); and a control unit (80) that has an operation section (70) for causing the building material (1) to be cut as desired by the articulated robot (40). The control unit (80) performs control so that the cutting means (30) cuts the building material (1) while the cutting means (30) and/or the clampers (11 to 18) avoid contact therebetween.
