上海求新造船厂为适应造船工业的发展,于一九七○年研制成功我国第一台高精度绘图机。一九七一年求新造船厂和我们组成了三结合科研小组,探讨数控绘图技术。我们的主要研究从开始至今都是放在产生曲线的方法上。因为对于造船来说,将离散的船体型值点,连成光滑的曲线,已在数学放样中解决。数控绘制曲线的主要矛盾是克服误差的积累。开始我们的指标是绘制二米长的曲线误差不得超过30丝。我们着重分析参照线切割机走圆的方法,将其观点提高推广。经过一年多时
Shanghai Innovation Shipyard to adapt to the development of shipbuilding industry, in 1970 successfully developed China’s first high-precision plotter. In 1976, Shinchung Shipyard and we formed a three-pronged research group to discuss numerical control drawing technology. Our main research has been devoted to generating curves since the beginning. Because for shipbuilding, the discrete hull shape points, even smooth curves, have been solved in mathematical lofting. The main contradiction of NC drawing curve is to overcome the accumulation of errors. The beginning of our indicator is to draw two meters long curve error shall not exceed 30 filaments. We focus on the analysis of reference line cutting machine to round the way, to promote their views. After more than a year
