1996年1月18日在西安飞机公司计算中心内,西飞总工程师和波音公司材料部合同执行总裁一起按了CATIA系统的绘图指令,由波音工程师在大洋彼岸设计、贮存在软盘上的波音737-700垂尾模型,从西飞公司的AO超长绘图机上徐徐绘出。至此1500架份的波音737-700垂尾的转包生产正式启动。这项1995年8月签订的合同,占波音该项目需求量的50％,总金额达几亿美元,也是西飞公司迄今为止数量、金额最大的转包生产合同,1997年底首架份垂尾将交付。波音在737-700研制生产中,全部采用了以CATIA软件为主的计算机设计、生产、检测一体化技术,在计算机上直接设计、绘图,生产中把数据直接输入数控和检测设备,不用做很多模拟件,省略了中间环节,消除了生产过程中越来越大的误差积累,提高了效率,节省了人力。作为波音737-700垂尾的供应商,西飞公司得到的不是过去那样大量的具体
January 18, 1996 in the Xi’an Aircraft Corporation Computing Center, XAC Chief Engineer and Boeing Materials Division, the contract executive president together according to the CATIA system drawing instructions by Boeing Engineers across the ocean design, stored on floppy disk Boeing 737 -700 vertical tail model, from XAC’s AO long plotter slowly drawn. At this point 1500 copies of the Boeing 737-700 vertical tail subcontract production was officially launched. The contract signed in August 1995 accounted for 50% of Boeing’s demand for the project with a total amount of several hundred million U.S. dollars. It is also the largest and largest amount of subcontract production contract ever made by XAC. At the end of 1997, the first vertical tail Will be delivered. Boeing in the 737-700 development and production, all using CATIA software-based computer design, production, testing integration technology, the computer directly on the design, drawing, production, the data directly into the NC and testing equipment, do not do a lot Simulation of parts, omitting the intermediate links, eliminating the accumulation of more and more errors in the production process, improve efficiency and save manpower. As a supplier of Boeing 737-700 vertical tail, XAC did not receive as much specific information as in the past
