The invention discloses a shipbuilding precision control method utilizing unilateral datum, which comprises the following steps that: a datum line is arranged on a datum edge of the unilateral datum from the beginning of a blanking stage, the datum line is from the beginning of butt joint of parts to the end of carrying, and the datum line is used for a long time and is a datum for realizing butt joint line shipbuilding; when a ship body works, all parts are assembled or segmented, lineation is carried out on a unified datum according to the same size, and the lineation is used as a datum which is set for guiding field operation personnel to ensure that a good ship body is manufactured in the assembling and total assembling/carrying stage. Unilateral datum construction application standardization is achieved through design, production, inspection and feedback design improvement, and the construction technology is formed. According to the method, the unified datum of the whole ship is improved, a previous cross curve shipbuilding process method is replaced, the serious phenomenon of the repairing and cutting rate caused by margins existing all around in the past is improved, meanwhile, the repairing and cutting process is moved forwards, the original groove retention rate is increased, the dock tool opening rate is reduced, and cost reduction and gain are achieved.

    本发明公开了一种利用单边基准的造船精度控制方法,所述控制方法包括:单边基准从下料阶段开始就在基准边设置一条基准线,该基准线是从零件对接开始直到搭载结束,长时间使用,是实现对合线造船的基准;船体作业时先把各零件、组立或分段,在统一的基准边以相同的尺寸先进行划线,该线是作为指导现场作业人员在组立以及总组/搭载阶段确保制造出良好的船体所设定的基准线。本发明通过设计、生产、检验、反馈设计改进实现单边基准施工应用标准化,形成施工工艺。改进全船统一基准,取代以往的十字线造船工艺方法,改善以往四周存在余量导致修割率的严重现象,同时将修割工序前移,提高原始坡口保留率,降低船坞开刀率,实现降本增益。
