The invention relates to the technical field of
laser processing, and discloses a
processing machine tool and a
processing method for a special-shaped polyhedron. The
machining tool comprises a base, a stand column arranged on the base, a control device, a first adjusting mechanism, a rotating mechanism, a second adjusting mechanism, a
laser mechanism and a linear scanning device, the first adjusting mechanism is arranged on the base and used for adjusting the position of a blank to be machined in the X-axis direction and the Y-axis direction. The rotating mechanism is in transmission connection with the first adjusting mechanism and used for driving the to-be-machined blank to rotate around the A axis and the C axis. The second adjusting mechanism is arranged on the stand column and used for adjusting the positions of a
cutting head and a
line scanning device included by the
laser mechanism in the X-axis direction and the Z-axis direction, and the
line scanning device is used for obtaining
point cloud data of the to-be-machined blank; according to the processing
machine tool disclosed by the invention, the control device is matched with the linear scanning device, so that the
cutting precision of the processing
machine tool during processing of special-shaped polyhedrons can be improved, and the adaptability of the processing
machine tool to complex shapes is enhanced.
