The sources of energy expends big unit basically is cooling and lubricant pump. Use the rotate speed below high-pressured condition to adjust, the sources of energy that OK and managing the sources of energy supplies a machine tool has 20% ～ only 40% be used at its main function, for example, use at the metallic cutting craft of component on milling machine. This is meant, there is the tremendous latent capacity that can have discussing in this respect. Study a project to go up jointly in NC-Plus, 9 partners devote oneself to the sources of energy that milling machine regular job status leaves to use up reduce 30% . However, of single component optimize can't achieve this goal, be necessary to let whole machine and machine treatment process realize integral sex to match so, use control system to give to energy management support. So, project federation composition includes machine tool and component to make enterprise, user and school partner. The machine tool is a complex system, its composition includes many functional unit, and in in principle, want to satisfy the client's requirement. Here, manufacturing task, if precision, periodic time is mixed,flexibility is main influencing factor. This means us to be obtained impossibly " off-the-peg " efficiency measure. NC-Plus studies the project shows an improves fundamental efficiency measure that provides wide perspective extremely, with respect to its economic benefits character, be necessary to undertake assessment to the one by one of specific application circumstance of these measure. High-energy source efficiency is the result that takes a series of step the foundation that studies a project jointly is pair of milling machine of demand of whole in process energy measure. These measurement, besides rate of flow of the sources of energy, the compression that still includes oily temperature of discharge of pressure, cubage, cooling lubricant, cooling water, hydraulic pressure and machine tool air is used up etc. These measure data to provide research machine tool to 3 stature projects the foundation of different domain: NC coordinate, fluid and hot concept and control system. The subproject studies the result will arrive integratedly in archetypal project, in archetypal project, can undertake test and verify through measuring to energy conservation circumstance. The controller of handling center of treatment of graph 1 DMC 80 H has all sorts of functional NC-Plus projects to begin on NC-Plus in July 2009, will continue to be carried out in June 2012. Now, had gained the knowledge of many concerned energy conservation. Among them, research of a stress is cooling system. In NC-Plus project, developed new cooling strategy, cooling device relies on air to undertake cool and be not used compression air. Intelligent adjustment uses hot model, have the aid of the help of these hot models, can be changed to structural sex and all sorts of control strategy undertake assessment. Use up to avoid needless the sources of energy, stop in machine tool main shaft, when having treatment task, control system can shut cooling system automatically. Additional, the milling main shaft of new development also balances to the sources of energy in cooling circuitry improve play to wear contributive action. Because took a series of step, compare with photograph of groovy main shaft, the efficiency of main shaft of this kind of milling raises a higher level, accordingly, need fewer refrigeration. Be in in machine tool or craft still do not have treatment task, perpendicular coordinate is secured when be not being moved, the brake of innovation sex can shut relevant gearing, consequently, make sure lower electric power is used up. Another the sources of energy expends big unit is cooling and lubricant pump. The test makes clear, below high-pressured condition, adjust rotate speed, OK and managing the sources of energy. Besides rotate speed adjustment, the side is supplied in cooling lubricant, used cubage discharge to adjust, such, to every kinds of machine tool, can presetting pressure or cubage discharge. To cutting bits purify and refrigeration, cubage discharge is important parameter on the technology. On energy efficiency, the machine tool controls a system to having core effect. Intelligence changes a concept to be able to keep away from power aiguille, executive the sources of energy manages. In this respect, need controls a program to undertake matching to component. The job that control system also wants to will examine the machine tool subsystem such as cooling device or cooling lubricant system serves as the task of oneself. Any moment are become when craft is concessional, be about to let its enter reserve condition. In NC-Plus project, developing a kind of program, gather all craft information, this function comes true on control system. Nextpage pursues in the 2 missions that execute in controller of DMC 80 H, include what allow in craft to allow when to be awaited, the subsystem such as will cooling pump or cooling and lubricant system optionally switch comes reserve sex of whole of sophisticated technology need evaluates mode to resemble machine tool itself same, shifting efficient work also is complex. Why to plant measure, why planting below the condition, bring about why to plant benefit, depend on a lot of elements. The information that concerns specific applying is more accurate, machine tool with respect to more can effective ground, with taller efficiency adaptability the ground matchs to it. But, even if all-purpose machine tool, also can press what be opposite according to relevant craft to undertake optimizing adjustment, develop tremendous energy-saving potential. Who is the backside of efficiency factory and NC-Plus project, what are they doing? Efficiency factory (Efficiency Factory) it is federation of manufacturer of German machinery equipment (VDMA) be taught with German federal and study a ministry (BMBF) an activity that combines initiate, the tenet is promotion communication be taught in German federal and below research department support with " the energy efficiency in production " 31 begins for the theme combination study the newest achievement of the project. The partner of many 200 industry and scientific research unit creates catenary research and development to give multinomial energy efficiency to manufacture a technology along value. Involves research project includes thematic field " the machine that efficiency produces and establishment " the NC-Plus research project inside. This project began in July 2009, ended in June 2012.
