我所光电跟踪线切割机床在学习兄弟单位先进经验的基础上,完成了机床的设计制造与调试,其中光、机、电设备都是自行设计与制造的。光电头部分采用亮度差动法。在跟踪墨线(?)90°的锐角时,除20°以下锐角用R=0.5毫米圆弧来过渡,其余均不用圆弧连接,当两条跟踪墨线最小线距为1毫米时,光电头仍能辨别而不偏离墨线正常跟踪。这是因为在光电头部分解算装置中,采用了较高精度的正弦—余弦函数同位器(简称正余弦函数同位器),来代替正余弦函数电位器,而得到较理想的跟踪性能,以此解决加工复杂形状零件,克服数控切割机对复杂形状零件编程序的困难。这种跟踪性能对航空工业中飞机外形铝板与造船工业中船体钢板的跟踪切割有一定意义。
Based on the advanced experience of our brother unit, our photoelectric tracking wire cutting machine tool has been designed, manufactured and commissioned. The optical, mechanical and electrical equipment are all designed and manufactured by ourselves. Optical head using brightness differential method. When tracking the acute angle of 90 ° of the ink line (?), The acute angle of less than 20 ° is used for the transition with R = 0.5 mm arc, the other is not connected by arcs. When the minimum line pitch of the two tracking ink lines is 1 mm, Can identify without deviation from the normal track ink line. This is because the optoelectronic head solver, the use of high-precision sine - cosine function homosexual (referred to as the sin-cos function homophase), instead of sine function sine potentiometer, and get better tracking performance to This solution to the processing of complex shape parts, CNC cutting machine to overcome the complexity of the parts programming procedures difficult. This tracking performance has certain significance for the follow-up and cutting of the hull steel plate in the aircraft industry and the shipbuilding industry in the aviation industry.
