A new type of ship's frame bender with computer numerical control (CNC) has been developed and installed in many shipyards. The bender has many advantages and will result in significant cost savings and increased production efficiency. The CNC bender is compatible with existing shipyard automation programs, using the frame data generated by a computer-aided design/computer-aided manufacturing (CAD/ CAM) system to produce a formed frame automatically. The bender can straighten deformed beams in both horizontal and vertical planes, as well as bend them in the horizontal plane without out-of-plane deformation. Markings can be stamped at the required position in the bending process.
