[0002] The CNC system is a special real-time multi-task computer system. Its control software integrates many advanced technologies in today's computer software technology, among which the most prominent are multi-task parallel processing and multiple real-time interrupts. They are introduced below. On large CNC machines, workpieces weighing more than several tons or even more than ten tons are often encountered. Due to the heavy weight of the workpiece, it often takes a long time to straighten the workpiece using traditional methods.

[0003] The original method of straightening large CNC workpieces is to use a copper hammer to hit the workpiece to achieve the purpose of straightening the workpiece. This operation is labor-intensive and easy to damage the workpiece. At the same time, it is difficult to quickly align the workpiece to the ideal state due to poor control of the force. In addition, this operation is also easy to damage the calibrator due to operator errors, and the vibration of the equipment due to strong knocking force can damage the CNC precision parts.
