Machine control designs 10 great skill

Investigation, research and quantify collect information, make a plan, advance fastidiously to fixed target next. This is a portraiture of machine design technological process. To go after the flexibility of product height and adaptability, when engineers are designing a product, constant regular meeting expends many time and energy, add new function to the product ceaselessly, what bring about a product finally however is excessive and complex. The father MichaelGurney of company of compositive business ConceptSystems mixes industrial system EdDiehl says: "In products plan, once decided first order, that should immediately from most the place of be to one's profit begins. About the process control and quality pilot statistic are analysed is very useful information. " 　 　 " modular machine design and the customer that production method can satisfy constant growth on one hand make the design demand that change, shorten on the other hand the development time of the machine, still can reduce the production cost of OEM at the same time. " LarryKomarek of manager of product of PhoenixContact company automation says. Komarek still suggests to say: " the machine or machine series is decomposed for different functional component, each function component has corresponding machine, dominate component and software program oneself. these functions collocation combines the component to be able to found an user guest to make the configuration that change or ' small-sized / medium-sized / large ' range of products. The course is designed beforehand, the functional part that documentation is changed and tests beforehand beforehand can be come out by fast production, and still reduced manufacturing cost. " 　 of 　 　 　 2.

Standard and Gurney of 　 of safe 　 　 and Diehl point out, the general interface of standard of have the aid of, the product is OK and compositive first-rate system component, the equipment past the appointed time that still reduced special control system at the same time discards as useless wait for a problem. The knowledge that accumulates in designing software is OK by code of translate into machine, avoided the modification to designing parameter thereby. Some designs software offerred the data converter that faces STEP and IGES file pattern. STEP, namely product model data exchanges a standard (ISO10303) , defined the product information that how be described and exchanges digitlization. "In NECcode should making full use of when designing distributinging control group group electromotor installs a regulation (Groupmotorinstallationprovisions) the 430th.

53(c) . The profit that such doing is, can reduce the amount of branch circuit, reduce cost, eliminate EMC noise, need not new wiring and debug can change each function module, enhanced the flexibility of the product. " the RichMintz of electronic product manager of SEW-Eurodrive company says. The LarrySunday of manager of machine safety product of SchneiderElectric company says: "In safe respect, since NFPA-792002 year since revised edition is released, all general machine designs should observe IEC60204-1Category4 standard. It is the top level of safe standard, ask all machine designs should consider safe relay and safe chain unit. " at the same time he mentions again: "Revised edition united NFPA-79 and IEC60204-1 international standard 2002 rise. The customary practice of American is the relay that uses a level in dominating circuit basically, in order to assure so called ' control reliability ' . But to IEC60204-1Category4 standard, this is far insufficient. " 　 of 　 　 　 3.

Sensor and machine vision 　 " the issue that just does not consider sensor in design evening. The sensor of small-sized intelligence often can bring the profit that expect is less than. In component motherboard space already affirmatory circumstance falls, a good in quality and cheap in price sensor can solve big problem sometimes " , the JosephDolinsky of technical market manager of BannerEngineering company says. The MarkSippel of manager of market of product of In-Sight vision sensor of Cognex company points out, use why to plant pattern processing detects and process feedback depends on a lot of elements. These elements include: Whether does feedback information need to detect in multichannel disperse, restrain or share between other system? Whether to need to a controller is in charge of detecting result and the harmony that assist the task? How communicate and to how communicate and use detect result? If I/O equipment is used at communication, what are the so other types that dominate port? Where is the position? Lamplight, power source and data are transmitted wait for an element to also need to be considered. 4.

The data of industry of NationalInstruments of 　 of 　 of logistic platform 　 of soft hardware collects and the product manager RahulKulkarni of control branch says: "The machine devises the first step of long journey, choose a logistic platform correctly namely. The controller that uses generally now has: PLC, PC-104, PCI, the circuit with groovy perhaps PXI board. Before the decision adopts which controller platform, must mature all function that this controller wants to carry out (detect logistic control, process control, sport control, automatically for example and machine condition monitoring) . Process designing tool should master easily, generated code should be modular, Yi Sheng class and but of put sb in a very important position. The DanSeger of global OEM technical adviser of RockwellAutomation says: "Make choice of controls framework solution to become simple with making design. From controller and network technology, to peripheral equipment and operator interface, if the choice to these component considers from the angle that purchases cost lowest only, can bring a trouble to later period development so. Same, connect goodly quality (for example each equipment component compact assemble, close together communication) can rise efficiency and reduce cost. Contrarily, if those who use is in in the design,be cheap equipment communication plan, so use hard not only, and can be in the project is initial and safeguard level to expend many time. " to obtain first-rate result, the process designing job that he suggests to share control and information two parts undertakes apart. Other valuable practice still includes: Data form of structuralization, pull-down menu and the are based on code object library that classify according to the function. 5.

Basis of actuator 　 　 applies need, choose appropriate pneumatic, hydraulic pressure and electric actuator. Same, athletic controller also needs serious alternative. So, can you use electromotor to control unit (MCU) or digital signal processor (DSP) undertake electromotor is controlled? The electromotor of TexasInstruments controls proposal of politic expert KedarGodbole, should seek function innovates and reduce systematic cost, the balance is acquired between function and price (obtain first-rate sex price to compare) , efficient C/C++ kernel is used in fast software development, use the tool that uses easily neatly, and the imitate that undertakes Gao Shuiping is compositive. The JanLindholm of SEW-Eurodrive company says: "Chafe at machinery relatively orgnaization, control an orgnaization often more applicable and efficient. Wait for similar solution photograph to compare with brake of separation and reunion, transducer (especially of closed circuit) can lengthen cycle to 2 to 3 times, still can reduce the cost that wear away and maintains of equipment at the same time. " Lindholm explains again say: "Technology of frequency conversion drive and without sensor vector vector of control, magnetic flux is controlled and communication is not had brush servo photograph union, can solve problem of drive of a lot of electric machinery.

Indication screen and pushbutton, bad of what actor what? The man-machine interface that is based on indication screen (HMI) with pushbutton, bad of what actor what? The answer is: Using feeling screen to replace pushbutton is beneficial. The pattern plate adaptability that HMI kit takes oneself is strong, and can put sb in a very important position. The JoeRubino of manager of software product market of OmronElectronics says: "HMI still has a few otherer advantage, if data interconnection is mixed,diagnose ability. Diagnostic ability can bring a machine soft hardware is the advantage on normal run time, handy connect ability and reduce process designing workload, it is content is worth somewhat really. " 　 of 　 　 　 7.

Network and communication 　 　 use network technology to be able to reduce the workload of wiring of machine inside and outside and communication coding. The marketing expert DavidCrump of Opto22 company says: "The machine is right machine (M2M) communication technology enhanced a machine connect quality. Have the aid of at wireless technology, can rise machine equipment and join of business information system, implementation is long-range equipment monitoring and start, the report when producing state seed and a few otherer operation. M2M still can help a machine design personnel to dog the lifecycle of the machine, identify trouble site, improve prospective design. In the meantime, m2M still can create more battalion to receive an opportunity for the enterprise, for example, provide lead for the user equipment is safeguarded and the appreciation such as maintenance serves. " the Kulkarni of NI of 　 of 　 　 　 says: "Wireless technology sort is various. Correspond to the M2M between long-range computer and factory HMI/SCADA system, because transmit a distance to be as long as hundreds miles, should use satellite communications so or means of beehive telephone communication. To controller / the communication between PLC and HMI/SCADA system, IEEE802.

Technology of 11 wireless communication is the most applicable. However, to the communication between controller and sensor, because transmit a distance to have 10~100 rice only, use blue tooth technology or Zigbee technology is more effective. " the Seger of RockwellAutomation of 　 of 　 　 　 points out: "(when designing the communication between different equipment) should avoid to use RS-232 and technology of standard aether net, want to expend many time to write appropriative communication driver to support data to transmit otherwise. This is a take time arduous and won't the job of appreciation. And in-house to the machine, if I/O class uses a safe terminal,the technology can save the time that assemble and overhauls. " the market manager DeanNorton of Wago company says: "Of Wago company avoid pinchcock of screw basket type to hold (CageClamp) terminal has taller flexibility, can shorten the wiring time of 60% , in some application the circumstance can absolve every the 6 need that have consolidate to the machine to 8 months. This wiring technology can come true beforehand wiring, satisfy the requirement of all machine I/O, can go to the lavatory to use appropriate bus line agreement to realize the communication of controller in design later period. " 　 　 8.

　 of power source 　 buys power source system directly, and do not try oneself design them, can save a large number of time and energy so. System of power source, bus line, management and intelligent component can submit a report to HMI, can achieve more expensive system so compositive with efficiency. Segregation, monitor and screen measure can make sure the smallest transmission line and EMF are disturbed. 9.

It is OK that compositive 　 　 considers a machine to design from the angle of whole production technological process huge improves efficiency. The CEOFredrikJ Sson of FlexlinkSystemsAB says: "Normally the circumstance falls, the ability of product line of a machine was developed only 30% . If can shed the angle of Cheng to consider mechanical design from whole production, so the utilization rate of product line can be raised greatly. " the information that 　 　 　 comes from a machine tool integratedly can arise than machine itself more benefit. A few main projects are designed and produce an organization to point out, STEP database can reduce be as high as respectively 35% plan with the production of 75% and make control cost (data origin: StepToolsInc) . 10.

When seasonable project sums up 　 　 to near end when the project, might as well smoke some of time to undertake evaluate and be summinged up to the project, the design that falls in order to go to the lavatory one round. CNC Milling CNC Machining
