我厂从1970年开始,同六机部第十一研究所、一机部西安仪表厂研究所,以及浙江大学等单位,实行厂、所、院校和工人、干部、技术人员两个“三结合”,着手进行我国造船工业第一台数控绘图机——SHD—1型数控绘图机的研制工作。这台绘图机于1971年5月调试考机结束,1972年9月用“正负法”绘出了我厂建造的第一艘石油勘探船肋骨线型图,而后又逐步完善,终于达到能够绘出符合生产要求的各种船体图形的程度。此台SHD—1型绘图机,已于1975年8月在六机部船厂数控设备经验交流会
I plant from 1970 onwards, with six Eleventh Research Institute, a machine Xi’an Instrument Factory Institute, and Zhejiang University and other units, the implementation of factories, institutes and institutions, and workers, cadres and technicians two “three Combination ”, proceed to China’s shipbuilding industry’s first CNC plotter - SDH-1-type CNC plotting machine research and development work. The plotter was completed in May 1971 and the test computer was completed. In September 1972, the “positive and negative” method was used to plot the line pattern of the ribs of the first oil exploration ship built by our plant, and then gradually refined to finally achieve Draw the extent of various hull patterns that meet production requirements. This Taiwan SHD-1-type plotter, has been in August 1975 Shipbuilding Machinery Factory Shipyard experience exchange meeting
