Enhancing safety in dangerous industries
Diakont Group, consisting of ZAO KTPI Gasproject, ZAO Diakont, OOO Diakont Innovatica, Diakont Advanced Technology (USA), and Diakont s.r.l. (Italy), develops, manufactures, and delivers high-tech safety systems for the nuclear and natural gas industries. The group also offers hazardous facilities monitoring and maintenance services, and designs and constructs such facilities.
Company experts with extensive hands-on experience in high-tech equipment design perform the entire product engineering cycle, including mechanical and electrical design. ZAO Diakont has a production facility with modern high-precision numerical control (NC) tools. The facility includes machining and assembly shops equipped with coordinate measuring machines (CMMs) and printed circuit board (PCB) assembly lines.
Gradual move to design automation
Diakont Group has taken a step-by-step approach to deploying computer-aided design (CAD) and computer-aided manufacturing (CAM). Initially the development process involved a number of different inhouse solutions used for design, and there was no document management system.
In 2004, company management decided to switch to commercial CAD software. They selected a CAD system with a simple and affordable licensing plan but, by 2007, the amount of design projects had grown and it became obvious that this solution – basically a “digital drawing board” – was not sufficient. Management then began looking for a new, more advanced solution.
They chose Solid Edge® software software from product lifecycle management (PLM) specialist Siemens PLM Software on the basis of the system’s comprehensive functionality. For instance, Solid Edge supports 3D modeling and the automated creation of drawings, views, and sections from a 3D model. “This is really important since we have not switched to a totally paperless process and sometimes we still use production drawings,” explains Mikhail Uvarov, head of the Analytics department at Diakont Innovatica.
Other reasons for choosing Solid Edge included the fact that the system is totally adapted to the Russian language; supports the national ESKD (Russia’s Unified System of Design Documentation) standards; is customizable to meet the company’s needs; and includes ready-to-use databases, knowledge assets and an engineering handbook, as well as help files and self-learning tutorials.
The company noted that Solid Edges outperforms its competitors in terms of price/performance.
CAM came next
As the number of numerical control (NC) tools increased in 2011 and 2012, it became clear that shopfloor programing was no longer an option. After considering several competing CAM solutions, Diakont selected NX™ software from Siemens PLM Software.
NX was chosen primarily because its CAM functionality takes greater advantage of the capabilities of the company’s NC machine tools compared to competing solutions. It also supports the specific features of the company’s tools and controllers, so there is no need to make corrections to the postprocessor’s output. In addition, NX CAM supports user-defined postprocessor commands and cycles, as well as customized machining templates.
Moreover, Diakont takes advantage of the extensive functionality of NX CAM, including solid modeling; assembly creation and machining of assemblies; and drafting (for the creation of manufacturing drawings and setup charts). The company also utilizes the software’s programming for turning operations and multi-spindle lathes and multi-axis milling.
Since Diakont now uses integrated CAD/CAM functionality, the time needed for software training has been significantly reduced. Also, since Siemens PLM Software provides file format compatibility between Solid Edge and NX CAM, Diakont did not have to spend any effort on integrating the two systems, with manufacturing planning completely automated.
The software deployment was a multistage process. First, two Solid Edge seats were purchased for a trial run. The trial was supported by training and seminars. “It was a pilot deployment. Company management wanted to evaluate the system’s value prior to making it a company standard,” recalls Uvarov.
He says that initially two designers were trained and began using Solid Edge to identify the system’s benefits in terms of document quality, performance and so on.
Having analyzed the results, management decided to gradually increase the number of licenses of Solid Edge. In 2012, Diakont standardized on Solid Edge as its primary design tool, and the company now has 60 seats of Solid Edge. The system is used for developing complex parts that require NC machining. In 2014 the company purchased NX CAM for some of its manufacturing engineers.
Today, nearly all projects at Diakont are developed using Solid Edge, while NX CAM is used for creating NC code for many equipment types, including the Moore CPWZ500 jig grinder; the Mazak, Datron, DMG and Mikron milling and mill-turn machining centers; the Sodick wire electrical discharge machining (EDM) tools; and many others. Presently the company is commissioning the Traub TNL 18 Swiss turning machine for batch roller drive manufacturing and expects to see significant productivity improvements.
