| Abstract: | Bending machine is an important infrastructure for sheet metal manufacturing.A new high-power all-electric CNC bending machine based on open CNC system was presented.Industrial PC,motion control interface board and servo motion control system were used to build system hardware.Real-time Linux operating system with RTAI extension was used to install the professional CNC system EMC2 to ensure system’s computation power and real-time response.In y-axis,the high-power was achieved by adopting 3 servo motors drive synchronously.Not only bending precision is improved and power requirement is met,but also cost is reduced,the low efficiency and low bending accuracy of traditional hydraulic bending machine are effectively overcome.Practice has proved that the manufacturing precision and bending efficiency of the new all-electric CNC bending machine are high. |
