01mm arrives 0.

Between 05mm, when treatment, cutting tool makes fast and sharp movement scan edition roller surface, at the same time edition roller is rotating ceaselessly, can machine a face that has certain taper, use grinding treatment, can realize efficient cutting with simple cutting tool already, can simplify again construction of system. The grinding engine that abroad produces is to use complex relay pilot, put in dependability difference, plasticity difference, wiring rate of complex, automation is low a series of defect, and enhance market competition ability to be in increasingly intense competition, choosing PLC to regard control as unit is relatively proper program. The servo that the article put forward to use transducer and unit of control of PLC fixed position forms the opinion of grinding machine and method, gave out to control a system the design program of structure of soft, hardware. 1 technological process one electrify, procrastinate board the servo that is apart from with control feed clears, begin to detect to realize appropriate feed to be apart from then, detect end begin real grinding process. In system of grinding engine control, will control through 3 transducer use at procrastinating board mobile, bit body is rotational, the electric machinery with edition rotational roller, PLC(of application of system of feed of bit body main shaft can make up controller) fixed position servo controls a system, will achieve certain feed distance through servo, grinding gives the edition roller of a requirement, always grand input of high speed of FBs-MN series PLC reads the reading that takes the probe when detecting. Photoelectricity is close to switch outfit to be on roll annulus, procrastinate board signal of pulse of length translate into, use the tally that can make up Cheng controller to have count, when computation value achieves set to be worth, control procrastinates board stop shift, demand of precision of transverse and mobile control is not high, with PLC interior tally comes true can, managing cost. Sparge a powerful person moves in the machine when, spray to edition roller cooling fluid, will make sure figuration roller does not suffer wear away those who reach profile surface is bright and clean degree. The accuracy of the intelligent sex that the flexibility of the security that uses to increase product line, reliability that run, maintenance convenient sex, operation, breakdown diagnoses, grinding, the control system of the design is used automatic (include thick cut, essence of life is cut) / the hand changes control way. When choice hand moves an operation, open through feeling the soft pushbutton on screen to realize equipment, stop control, operate handle to control servo enter or retreat a dot to move, facilitating equipment debugs maintenance. When choosing automata, amount of length of roller of edition roller diameter, edition, cutting is set on feeling screen, show the maximum of edition roller diameter when detecting, the information such as the least value and average and the breakdown information that detect, also rose to control convenience sex thereby. Change the set frequency of transducer, procrastinate convertibly board rotate speed of roller of edition of floating rate; coming back is spent and bit body rotate speed coming back is spent. The hardware of system of control of PLC of 2 grinding machine is designed 2.

Composition of equipment of 1 grinding aircraft and engine of design target grinding are main by PLC of 1 series of Tai Yonghong FBs-44MN, series of MR-J2S of a 3 water chestnut communicates servo, transducer of series of FR-E540 of 3 3 water chestnut, the 510T of a WEINVIEW, module of a 4DA is comprised. Its core is to be able to make up Cheng controller, its output basically is used at dominating servo and drive electric machinery partly.

LC of Man of majestic take along sth to sb: FBs-44MN is finished detect (computation gives first-rate feed to measure) , the working procedure such as automatic grinding. ② uses servo to realize the double closed-loop control that measures to grinding feed. ③ uses in-house tally and photoelectricity switch to read take transverse procrastinate board mobile distance. ④ used feeling screen to realize more convenient, friendly man-machine communication. 2.

2PLC control system makes control system by but FBs-44MN of controller of process designing logic, servo, photoelectricity is close to switch and D/A to expand module and feeling screen component are comprised, in realizing grinding process basic and logistic movement, detect, does servo of 1) of 4 big functions mix servo closed-loop control and man-machine communication the combinative module: of fixed position controller? Scepter of  of ハ dice  carries Chang to fasten male Du Tao to brag commonplace で holds Xi Mi of M of box of an insect destructive of the roots of seedlings setting out high to black  knows well  of boundless and indistinct of extensive of sneer  Nai Lang chaos suffers from commonplace ぱ  to punish  benefit tadpole  Fei is foolish W of idle of Gua of  of ぜ of poisonous Fu Xian, the diameter that shows edition roller according to formula is the biggest, the smallest, average (with make appropriate cutting measure concerned) , subtract with right now servo reading next probe reading, plus the cutting of need the quantity seeks an exacter feed amount, begin process of whole and automatic grinding finally. The fixed position program that the fixed position controller that FBs-44MN turns as intelligence weaves by the user gives out fixed position pulse, moving direction to wait to driver, signal driver controls electric machinery of signal drive servo to drive ball guide screw to have fixed position by these, to servo electric machinery, have end of servo preparation, servo and null 3 signal feedback, exterior set uses digital switch to be able to choose location the numerical value such as the position and speed to send a person fixed position unit, fixed position unit receives expander of FX series PLC to go up repeatedly through bus line, the fixed position intelligence in becoming PLC to control a system controls segment, inside fixed position unit, the change of the setting of constant and monitoring, parameter can join through using the data to PLC accesses unit to finish, because this is OK,module number is assigned by PLC in moving process (here 4DA is) of a module, the data such as speed of deferent fixed position, can monitor in PLC fixed position signal reachs the real time of GM to move or suspend status. Corresponding ground allocates in PLC have relay losing a person, output relay, assist relay, and the equipment such as special and auxiliary relay. Nextpage feed capacity is controlled with servo electric machinery, the control of servo electric machinery comes true by PLC. PLC generates two signal, it is servo pulse signal all the way, the rotate speed of its frequency and servo electric machinery becomes direct ratio, its several angle that decided servo electric machinery rotates. It is DIR of directional n signal additionally all the way. When DIR is tall n, electric machinery suitable hour hand rotates; is contrary, when DIR is low n, electric machinery is anticlockwise rotate. The cent in grinding is thick cut and essence of life is cut, the precision demand that essence of life cuts is very high, general cutting quantity cannot is more than 0.

05mm, servo advancement Lmm, delivered 1600 pulse, was equivalent to a pulse advancing 0.

625um, precision is very tall, make thereby guide screw gets exact location. When servo controls bit body feed, feed speed is not changeless, want to begin decelerate automatically when bit body is close to edition roller, lest cross quality of strong influence grinding. Control has 3 to be close to switch on the guide screw of bit body feed, one uses origin fixed position, additionally two are to enter respectively, retreat be close to switch. : of 3) transducer module?  enlighten Hu of order  Qi falls bone of lamp of Gan of cap of take along sth to sb of dispatch of cheek of  of  of common of ㄔ of discuss of buttock of  of Kun of magpie of Yu of Duo   blows Liang vulgar to black Cong of dainty of where D of Jian of  １ Gan Deng says Miao Gou Su chants mail?DA speed voltage is worth, according to the parameter of in-house set the value is opposite asynchronous electromotor timing. Timing pattern is WF model, pattern of this kind of timing is changing the output voltage that transducer changes while transducer outputs frequency, both ratio is calm, in order to maintain asynchronous electromotor magnetic flux changeless. This timing pattern is handy, reliable, can satisfy the requirement of electric machinery timing. Does 4) feel screen: ? LC of Zuo of ッ  bad closes suitably, the moving information feedback that makes much to the random of equipment operation control, many feels screen process designing to grant through be opposite with implementation, PLC and feeling carry serial interface news report between screen, connect a line concise, whole system is more compact, beautiful. The software of 3 systems is designed 3.

1Can be the design that PLC pilot software designs PLC to control software divided roughly for: of the following module? PLC of series of BS of Mo of an ancient earthen utensil for steaming rise of rotten basket of ∮ of rancorring Q of  of Wa of ㄌ of ammonia of  of ň of ⒈ of a huge legendary turtle of ハ of far  of ⒆ of Suan of Hu of ⒓ of  of thistle of the Jia that fasten red, its interior includes basic and logistic instruction, pace to enter suitable accuse instruction and functional instruction, cooperate the special statement of patulous module, process designing is agile, revise convenient and moving stability. Undertake initialization above all, initialization includes to procrastinate board, of guide screw of bit body feed and servo clear, the axis of bit body of control of one electrify servo moves quickly at 0 o'clock the position, corresponding servo reading is 0, procrastinate board also return according to need at 0 o'clock the position, if feed of bit body main shaft exceeds the biggest when giving the route, the system sends Cheng of favorable balance of trade to call the police, at the same time bit body main shaft returns null automatically. More troublesome is the expectation value that does not know to want cutting a few times to just can achieve grinding, to improve efficiency, the user can store commonly used grinding cycle rise to be used with equipment hind, and need not redesign grinding cycle. : of 2) DA module?  of  of E barefooteding  prevent electromotor of stage of? of straight Liao of  of deficient of Qun of be used to of  of  of silk ribbon  procrastinates move, the edition roller diameter that transducer basis inputs, edition roller length adjusts through calling formula electromotor rotate speed, make sure grinding gives the appearance of certain taper. 3 speed and edition roller diameter, there is particular mechanical concern between length, and memory of relation of this kind of convert is in PLC and call automatically before grinding come out, procrastinate board transverse and mobile distance is used be close to switch to detect, electric machinery every turn a week detects 5 switch (10mm) of guide screw advancement, plan 5 frequencies, computation moves 2mm, next certain distances had been marked when stopping, should procrastinate board when go back goes can stop shift automatically according to the computation value with good convert. No matter bit body rotate speed still is edition roller rotate speed, procrastinate board floating rate produces wave motion, can affect the exterior precision that grinding comes out, accordingly, when among them when a speed happening is fluctuant, additionally two rotate speed must dog quickly. No matter the hand uses rate of the set when the operation or foundation edition roller diameter, length gets roller of bit body, edition through formula, procrastinate board rate value, want to pass its cost transducer of 3 water chestnut. For this, we increase 4DA module. This module offers 4 output channel (should use 3 passageways) , voltage outputs mode, corresponding at - 10V-+10V. Electric current outputs mode, part corresponding at 4mA-20mA. 3.

Appearance of 2 feeling screen designs 510T to be chromatic liquid crystal, 256 kinds show.
