The automation program efficient application on cylindrical grinder is amounted to in

Summary: The article basically introduces a stage to amount to series of B series servo, VE transducer and in amount to general-purpose numerical control system and the application that go up in cylindrical grinder. In using, amount to general-purpose the tall open sex of numerical control system will realize distinction at machine tool of other numerical control the technology of intuitionistic input innovates, reach an operation the simple and easy, result that improves efficiency. Keyword: Servo is general-purpose cylindrical grinder of numerical control system is tall open sex is intuitionistic inputting 1 foreword cylindrical grinder is pair of embryo outside the circle undertakes abrade, right embryo dimension finish machining, realize embryo through finish machining at the same time the surface is bright and clean degree. Accordingly, cylindrical grinder is the machine tool with treatment very tall precision. And the work that its process is relatively fixed also, this gives in amount to general-purpose numerical control system provided the very good platform that shows tall open sex. Amount to in general-purpose program of dot of the indication picture of numerical control system, in-house PLC, I/O, in-house parameter program is open, according to demand is revised and can plan, can come true to machine the intuitionistic input of data to securing work relatively, do not need to modify G code program, make the work of handlers simple, simplify, improve efficiency. Cylindrical grinder of principle of job of 2 cylindrical grinder uses X of two servo axis, Y. Electric machinery drives collet and workpiece to rotate, in the meantime, emery wheel also rotates, heart of runner shaft of workpiece and emery wheel coming back is parallel two axes at X axis, direction of rotation is contrary, the attrition that passes emery wheel and workpiece surface processes work. The shift of axis of X of two servo axis, Y axis, change the diameter of workpiece and form. Cylindrical grinder belongs to the machine tool with taller precision, taller to the requirement of system of floor sills, guide screw, numerical control, servo. Traditional cylindrical grinder is to use hydraulic pressure to drive Y axis movement, this makes machine workpiece to get very big limitation. After use numerical control, the can control process of gender, NC automatic nap emery wheel of the position of Y axis and speed, make the limits that processes work increases greatly. Because the solutions of 3 numerical control cylindrical grinder that are based on a stage to amount to automation platform are used those who require design of sue for peace is different, the machinery of different machine tool and electric design also are the same as very much, amount to in general-purpose the open sex of numerical control system, the can oldest rate satisfies the special requirement of every machine tool. Rely on parent company stage to amount to the automation product with complete set, amount to in can with most economy, handy, efficient way, for solution of system of quantities of machine tool client. Use by in the solution of whole of numerical control grinder that amounts to system of numerical control of PUTNC-H4C-2 of tall open sex, stage to amount to transducer of series of ASDA-B servo, VE to comprise, can make machine tool manufacturer, final client gets satisfactory service and benefit the biggest change. 3.

If the graph is shown 1 times,the stage of system of numerical control of 1PUTNC-H4C-2 of technical characteristic graph of system of 1PUTNC-H4C-2 numerical control amounts to system of PUTNC-H4C-2 numerical control. If workpiece definition picture pursues 2 -- the graph is shown 5 times. (1) the systematic framework of open mode, embedded embedded PLC, can satisfy the different requirement of of all kinds manufacturer. (2) liquid crystal of high-definition clear LCD shows, the user can plan by oneself appearance content. (3) most drive 3 servo axis (X, Y, A) . (4) coordinate PLC development, can define key-press function oneself, make an operation more agile. (5) offer the standard was inputted at 24 o'clock and outputted at 16 o'clock, optional distribute I/O patulous unit, input at 56 o'clock, output at 64 o'clock. Graph picture of setting of work of sign of 4 2 of graph of picture of setting of work of sign of 3 1 of graph of picture of 2 workpiece choice pursues picture of nap of 5 emery wheel 3.

M02 (2) workpiece 2 machine program: Because machine the emery wheel a side of workpiece to have circular arc model, need to use G40 of instruction of compensatory of cutting tool radius, G41, G42 so. Need to make set in MCM parameter: 00012500;022Tool#1radiuscompensation (radius of cutting tool of the first group of R makes good omissions cost set) . O0002 G65P#430L3A#322B20.

1Series of ASD A -A of servo of communication of series of ASD A -A is entered rank model communication servo and servo of communication of ASDA-B standard type are a stage the product of 2 mainstreams servo that amounts to electronic group to part to be rolled out with 5 years at 3 years, can all-around the demand of contented industry user, special go up in the application of CNC machine tool, property performance is more superior. The stage amounts to servo needle to characteristic of domain of CNC machine tool: (1) 3 built-in and complete kinds (the position / speed / torsion mode) control function basically, can mix expediently on position control implement join. (2) it is good that trends answers a gender, servo rectifies calm time 1ms, sky to carry condition to fall - of 3000RPM ～ 3000RPM quicken time 10ms. (3) PDFF (Pseudo-Derivative Feedback And Feedforward) framework of able-bodied type control is corresponding faster, right exterior interference has stronger control compensation capacity, can assure instant of lathe tool cutting thereby, or when other outside force intervenes suddenly, servo locates or decide fast be affected very few, if pursue,5 are shown. (4) the automatic gain of servo adjusts a function, can assess laden situation automatically and gain of reasonable setting servo, make servo is debugged thereby simpler, quicker, and servo locates more essence of life is accurate, without surmount quantity and acceleration to rush too. (5) offer resonance to restrain function and low connect filter function, can remedy mechanical inadequacy and flaw effectively. (6) the stage amounts to ASDA-A series to enter rank model communication servo has function of graduation fixed position more, coordinate the I/O program of CNC system PLC, library of knife of servo of can relaxed implementation is controlled. 4.

2 amount to VFD-VE series magnetism bundle series of VFD-VE of transducer of vector control communication is a stage amount to a when rolled out 2007 to satisfy high-end market brand-new product, its frequency outputs limits to be 600Hz of 0 ～ , and V2H output more be as high as 3600Hz, can satisfy the control requirement of main shaft of high speed of CNC machine tool completely. Use unique position to control a function, the C axis function that coordinates H4CL-T system also can realize function of graduation of angle of main shaft random. VFD-VE series communicates transducer characteristic: (1) inside buy V/F, vector control; Torsion control, and the position controls a function. (2) frequency output limits is 600Hz of 0 ～ , the output of high-end type more be as high as 3600Hz. (3) speed controls precision: FOC+PG shuts loop control, can amount to + / - 0.

02% . (4) low speed moment of force: 0.

5HZ can amount to 150% . (5) can do motor parameter and laden inertia appraise to measure and appraise of curve of high speed weak magnetism measures a function. (6) function of the decelerate when mechanical stop a machine by cutting off the power controls power cut of function, instantaneous. (7) motor temperature is answered give protection (PTC) function. 5 last words machine course of study now to develop at full speed, and automation product is machining course of study to apply in great quantities. Can see, treatment industry is controlling stride to automation in whole. Amount to in general-purpose the characteristic that numerical control system has tall open sex, tall stability, there are very large development space and latent capacity on machinery of very much special treatment, other automation product is amounted to in cooperating again -- wait like guide screw of servo, transducer, coder, slideway, integral solution of composition, can make machine tool product of the client has qualitative flight on stability and quality not only, and the product that also can make treatment of machine tool place comes out, there is very old rate to rise on quality and efficiency.
