The entire feeding process of using a complete set of double groove molds for punching C-shaped steel manufacturers greatly improves the tapping effect, and the work efficiency of CNC cutting machine is also greatly improved. After cutting the punched C-shaped steel, the crack extends along the cutting edge of the steel towards the base, and the width of the crack is from the front end to the base. Gradually reduce to form thick, low plastic areas at the edges. The arrangement structure of cutting edges is similar to the structural changes in the affected zone of the heating zone, and punching C-shaped steel has varying degrees of compressive stress, which is the primary reason for delayed cracking.

在冲孔C型钢生产过程中，很难避免冷却过程构成的板材剩余应力。因而，钢板切开变形严重影响客户运用。因而，控制冷却技能的优化和剩余应力场的猜测已成为炼钢职业的热点。

It is difficult to avoid the residual stress caused by the cooling process in the production of punched C-shaped steel. Therefore, the cutting deformation of the steel plate seriously affects the customer's use. Therefore, the optimization of control cooling skills and the speculation of residual stress fields have become hot topics in the steelmaking profession.

In this work, different trajectories were extracted and tested, and the trajectory extraction algorithm was validated. During the steel cutting process of punching C-shaped steel, oblique cutting is carried out along a straight line to check the line and reinforcement. After Iterative reconstruction, provide the function of reconstruction picture and track parameters, and in some cases, summarize the track error, provide the tracking adjustment error algorithm, and adjust the error on the lower computer through serial communication.
