Suuren sähkökoneen 3D–mallintaminen myyntitarkoitukseen

Abstract

Tässä diplomityössä selvitetään, mikä olisi paras ABB:n nykyresursseilla toteutettavissa oleva tapa mallintaa yksinkertaistettuja myyntivaiheen 3D–malleja laivateollisuuden asiakkaille. Tutkielma tehtiin ABB:n yksikölle, joka suunnittelee ja valmistaa suuria sähkökoneita. Asiakkaat haluavat 3D–malleja usein jo myyntiprosessin alkupuolella, jotta he voivat integroida ne osaksi omia tilanjärjestelymallejaan. Toimittajat luonnollisesti haluavat toimittaa malleja helposti ja nopeasti. Aluksi perehdyttiin ABB:n nykyisiin myyntivaiheen 3D–mallinnusmenetelmiin sekä siihen, mitä ominaisuuksia asiakkaat tuotemalleilta vaativat ja milloin he niitä tarvitsevat. Tämä tehtiin toteuttamalla 14 puolistrukturoitua haastattelua. Haastateltavana oli sekä ABB:n insinöörejä että asiakkaita laivateollisuudesta. Haastattelujen pohjalta suoritettiin temaattinen sisällönanalyysi, jotta saatiin selville, mikä nykyisistä menetelmistä vastaa parhaiten kriittisiksi koettuja tarpeita. Todettiin, että nykyisissä olosuhteissa paras tapa tuottaa yksinkertaistettuja asiakasmalleja on tehdä ne detaljimallien pohjalta. Jos detaljimalli on 3D–mallinnettu, NX:n Linked Exterior –työkalua tulisi käyttää ensisijaisena ratkaisuna. Jos ainoastaan 2D–detaljimalli on saatavilla, suositellaan mallinnustyön ulkoistamista. Molemmissa tapauksissa 3D–asiakasmalli voidaan tarjota yhdessä työpäivässä. Ehdotettu menetelmä ei kuitenkaan tyydytä kaikkia asiakastarpeita. Asiakkaat haluavat mahdollisimman kevyitä mallitiedostoja, joiden maksimikoon pitäisi olla selvästi nykyistä pienempi. Lisäksi huoltotilojen sisällyttämistä malleihin pidettiin tärkeänä. Vaikka tämä on toteutettavissa Linked Exterior –työkalulla, manuaalista lisätyötä vaaditaan sekä suunnittelijalta että asiakkaalta.

In this master’s thesis, I propose a best practice for providing reduced 3D models to marine customers at sales stage at ABB, a company designing and manufacturing large electric machines. Marine customers often request 3D models early in the sales process to integrate them into their own spatial layouts. The suppliers naturally want to be able to provide models easily and swiftly. To examine what kind of product models customers want and when, and to map ABB’s current sales phase 3D modeling practices, I conducted 14 semi–structured interviews. There were both ABB engineers and marine customers among the interviewees. Using these interviews, I exploited thematic content analysis to find out which of the current methods suit for the needs considered critical. I find that the best practice is to extract the reduced customer model from detailed product designs. If the detail design is 3D modeled, NX tool Linked Exterior should be the primary solution. If, however, only a 2D detailed model is available, I recommend outsourcing. In both cases, a 3D customer model can be provided within one workday. The best practice, however, does not satisfy all customer needs. Customers desire as light model files as possible, and the maximum file size should be much lower than it currently is. Moreover, the inclusion of maintenance and service spaces in the models was widely requested. Although that can be done using Linked Exterior tool, manual extra work from both ABB designers and customers is needed.
