A contractor of famous national defence industry, use standardization to measure software, the great bottleneck problem that in solving craft of a treatment, exists -- large work is measured on all sorts of treatment facilities. Current, the treatment of large work is facing enormous challenge, examine this kind of spare parts is a very thorny issue likewise, undertake metrical to the component of complex system especially, already became a crucial factor in manufacturing technology. In fact, one of the biggest to industry of world national defence contractor BAE system company, inspection man is made already became the first class major issue that resolves this company to produce bottleneck problem, it must reconsider its be opposite the measurement technique of large work. The plant of BAE system company is located in the Minneapolis city of the Minnesota, be engaged in emitter of system of armor chariot, artillery, missile technically, intelligent artillery shell reachs the production that big, small-bore naval vessel prepares Chinese medicine by roasting it in a pan. The component of these device is very complex, volume is very huge also. Contractor of industry of this national defence discovers, come from tracker of the machine tool at many manufacturer, laser and CMM3 coordinate to measure through using machine, measure software platform to carry out standardization operation to, it can make its measure a technology to achieve running water to change the standard of exercise. System of artillery piece of advanced naval vessel of naval 155mm of certain United States (AGS) be machined by large weldment and element is become, its dimension can amount to 20 Ft of × of 35ft × 20ft (1ft = 0.

3048m) . In machining a process, solder to these of package examining is very necessary, in order to ensure its are soldering, treatment and the dimension integrality in assembling a process finally. Regretful is, these large parts are measured in numerical control machine tool or large CMM3 coordinate the process designing on machine and measuring ever was a nightmare. Mr Chuck Vogland is manager of control of quality of BAE system company, he is in charge of CMM3 coordinate measuring the application of machine. 10 years ago, this factory has 3 CMM3 coordinate to measure machine, but every are measured machine use different software. Mr Vogland says, used CMM3 coordinate to measure in the past machine metrical process needs for a long time, so that this factory produces engineers to must be in manufacturing plan additional add a certain number of hours, because CMM3 coordinate is measured,make up for opportunity is potential the time incur loss through delay that cause. Laser dogs appearance makes BAE system company can will measure what equipment applies at the spare parts. When the large work that shows in surveying a plan, can show its special advantage more accordingly, this company decides to measure the platform of a software on machine to undertake standardizing handling to these CMM3 coordinate: Introduced PC-DMIS to survey software system from the Wilcox Associates company of Hexagon Metrology group. BAE system company and company of its agency Productivity Quality (abbreviation: PQI company) with coact of Wilcox Associates company, offer concerned licence to use, groom and the service that the technology helps. PC-DMIS surveys software system is construction of an open mode surveys process designing system with what have CAD function, but with a series of measure mechanical equipment and measurement unit compatible use with form a complete set. The immediate gain that this passes initial effort and scores is: The Pro-Engineer CAD document that will be designed and can use in manufacturing company introduces PC-DMIS to measure software system to use directly, reduced process designing time substantially thereby. After this, this company from Brown&One is purchased to be mixed newly over there Sharpe company contain formerly the global CMM3 coordinate of PC-DMIS software is measured machine, use a kind of new control system and PC-DMIS software next, transformed a more vintage Brown afresh&Sharpe3 coordinate is measured machine. In addition, this company still purchased the PC-DMIS software of an edition leaving a line, such, it can adopt CAD model directly, the program with work out spare parts is established on the computer. Process designing leaving a line provided a kind of significant measure for BAE system company, the CMM coordinate that transforming about 40 through face-lifting measures the traditional program that uses on machine, changeover becomes the form of PC-DMIS. To onefold the changeover that measures software platform did not stop to use CMM3 coordinate to measure the measurement of machine. In a year of in the past, BAE system company purchased two Leica laser of contact bougie to dog appearance. These equipment contain the free corner coming back of 6, can serve as already measure a tool, also can measure as the portable CMM3 coordinate of contact bougie machine use. Be in proper when, can allow this company to measure this instrument move to undertake metrical to the side of workpiece, already can managing measure time, can reduce large work to measure the risk that produces when engine is locomotive to CMM3 coordinate again. In assembling a process, use laser to dog appearance still can rise solder speed, make the calibration of the spare parts more easy. When occurrence production problem, it is OK apace measures large element inside the workshop, make manufacturing engineer rapid thereby and understand the problem of a generation intuitionisticly. A 46in (1in=25.

4mm) the model that planar monitor can let inspector see a part that be measured clearly. Factory of this company Minneapolis shares 3 member that measure systematic process designing, among them two are full-time process designing member, another is pluralistic process designing member, they measure machine, laser to dog for CMM3 coordinate what work in appearance and environment of same process designing leaving a line is portable measured a system to develop PC-DMIS program. 2008, the Cordova sister factory that this company parts to reach its to be located in the Minnesota for Minneapolis factory introduced the Ingersoll machining center of linkage of a 5 axes. Every deployed software of bougie of a main shaft and server of PC-DMIS NC numerical control on stage machine tool, use at be being measured in the automation on the machine tool. Pass the application of this one system, achieved be measured on machine and process examines mediumly purpose, the adjustment with additional need is installed or use no longer portable measure equipment. Mr Vogland admits, to achieve the goal that detects on machine, to diametical 4ft (1ft=0.

3048m) head of treatment of 5 axes milling undertakes process designing needs to measure machine or laser to dog than CMM3 coordinate the process designing of appearance possesses higher skill. These two factories that an application engineer that comes from PQI company helps BAE system company founded first order, can make PC-DMIS software gets applied quickly consequently, in the meantime, the member that it is the process designing of this company provides very useful skill. BAE system company already passed a variety of means to be reached from platform of type of this one across a lot of gain were scored from the enterprise in measuring software. Will single software platform applies at all sorts of measurement equipment, also reduced greatly to detecting of personnel groom requirement, the major that also does not need those who be all sorts of types to measure installation service to differ again measures personnel.
