Sun,1994, born in July, Jilin Huaide, a cadre and senior engineer of Dalian Heavy Industry Group Co., Ltd., 1996- 1997, developed two-coordinate NC cutting automatic programming software and NC cutting automatic nesting software, and published 2 papers. Among them, automatic programming is suitable for professional functions such as double-arc fitting of non-circular curves and dynamic simulation of drawing parameters of intersecting lines. Automatic nesting is suitable for occasions where the plate size cannot be determined in advance, or nesting can be performed on site according to the feed size of the machine tool. The paper "Research on Automatic Layout System of NC Cutting Site" was published in 1998 "Proceedings of the Eighth National Welding Conference". The paper "Development and Application of Programming Layout System for NC Cutting Machine Tool" won the second prize of Excellent Paper of Liaoning Railway Society 1997. Two CNC flame/plasma cutting machines manufactured by Kota Sousa Co., Ltd. in Japan were reformed, and the function of on-site graphic nesting was realized on the machine tool. The computer floppy disk was used instead of punched paper tape, which improved the utilization rate of the machine tool by 30% and the utilization rate of the finished steel plate by 3%. The 1 CNC flame cutting machine produced by Mesa company in Germany was reformed, all the strong and weak control systems were replaced, and the torch head clamping was changed from Qigong to manual/pneumatic dual-purpose clamping device.
