High-powered machine tool needs tall efficiency CNC

Much axis moves, high speed treatment and expensive precision work, compound model the feature of the machine tool is many sided. But the CNC that there is tall efficiency rear in its moves in what ensure its are reliable. Compound model equipment need is mixed reliably, accurately quick control. To 5 axes machining center is mixed Che Xi or part are other technical craft at a suit compound model for the machine tool, also be such. In many labour the multichannel diameter that goes up to carry out all sorts of differring in order to secure rhythm to machine the task machines equipment (mix like much axis machine tool deferent equipment) the CNC with very efficient need. Was not the amount that can charge passageway and axis only to decide to control systematic efficiency, whether does the software that still uses somewhat move fast, reliable, and whether to offer first-rate to serve support to also belong to fundamental premise condition for manufacturer and user. This are very important to the equipment such as machine tool of mill of such as car. Although each machine craft to undertake apart, namely the disparate industry that treatment of car, mill is having respective channel respectively aspirant travel, also can use axis and cutting tool jointly. Its premise is each passageways can exchange information each other, achieve synchronism deliver and machine. The application of this kinds of many passageway has a bottleneck, the circumstance that spends synchronism in main shaft rotate speed coming back namely sets the complexity that delivers fully. 5 axes treatment needs to assist a function to be aimed at 5 axes treatment, the software function that can have equipment to reach its to control systematic potential to increasing undertakes be usinged adequately (graph 1) , the compensation capacity that still has the length that enhances cutting tool, direction and radius (TCP, TPC and TRC) , if cutting tool is right,process data cut a point (computation) compensation problem. If be special cutting tool (be like echelon milling cutter) , need input spy to fasten but the corrective numerical value that has in CAM software normally. After undertaking metrical to cutting tool, these numerical value can permanent in the CNC that protects existence Fanuc GE, pass key-press to be able to be called. Can simplify not only so NC process designing, still can realize the instant to change at the same time cutting tool, and need not change NC course. Graph 1 go up in this equipment, must undertake controlling maths to 86 axes and main shaft of 33 high speed analytic the premise that is high accuracy is opposite to satisfy the requirement of high accuracy, equipment makes manufacturer research and development all sorts of technology program, its characteristic expression is on rigid and admirable structure and mathematical drive technique. CNC also has main effect, because it needs control to move accurately,this is (graph 2) . The 30/31/32i series CNC of Fanuc GE company can offer 1 μ M~1nm to control the mathematical precision of step pitch. Graph the 2 software functions that can enhance existing equipment to reach its to control systematic potential to can make full use of when using 5 axes milling, the function with length of such as cutting tool, direction and radius compensation were entered to wait main in the collect in control system this kind of maths is analytic the premise condition that is high accuracy. In the meantime, mechanical component is all in all also. For example filar lever should be achieved as far as possible little space. The mechanical error that goes up somehow can pass CNC to compensation function is able to improve or be compensated, use recoil to compensate a function quickly for example, this kind of function is passed " Servo Guide Mate " software can come true almost full automatic the adjustment with instantaneous. Be aimed at taller precision, slope is compensated and still main shaft compensates a function to be able to be offerred point-blank use. CNC shoud be able to conduce to the manufacturing efficiency that improves cutting operation quite. Be aimed at the requirement on precision, the NC program on control system is OK highest precision or the oldest rate are optimized inside 1~10 class limits, of course this is alone undertake in the light of each programs and treatment flow. Because this is when rough machining, the importance prep above that machines speed everything; And when essence of life is ground, the set of high accuracy is crucial. If a workpiece is versed in in some a treatment hind be taken away, if be used at measuring, need to return the word that continues to accept treatment to equipment again after that, need to consider work place to compensate (Workpiece Setting Error Compensation) problem. The condition photograph that holds with original mix is compared, lesser dimension deviation unavoidable. This function is OK a correctional coefficient that measures a result to regard follow-up treatment as flow. Graph the 3 control that machine integratedly in the light of car, mill, the gender is disturbed to detect to very main effect since the effect of CNC avoid to collide " 3D interference detects " the function conduces to those who prevent collision happening. Because if machine tool main shaft in complex course,go up,this is extremely fast if moving, it always is existing the problem of a safe risk, operate personnel to need special caution at least. Through this kind inside the collision of buy controls a function, equipment production manufacturer and equipment handlers but have the aid of is opposite at geometrical appearance area of all collision danger (if cutting tool, workpiece, workbench is mixed,clip runs unit) have a definition. Control system is when the moving orbit of computational axis, can rise these spatial information and the band of cutting tool data that use at that time consideration, although be below the case that handles 5 axes order, also can avoid the collision incident of likelihood happening. Collision surveillance also applies to control to be in treatment process, collision monitors the function is producing effect all the time. Undertake detecting in the dry movement before handlers also can be being machined. Danger is interfered in what because discover in time,equipment is like in milling process and happen stop machine, criterion equipment handlers is monitoring make when the function is valid still relevant axial go back. Such, although he presses the word of wrong key-press because of neglect, also can avoid the happening of collision incident. 30/31/32i series CNC can provide a good basis for compound treatment, satisfy much axis and the requirement that much passageway machines. Control system has the processor that high speed runs and inside high speed bus line. Can realize fast data processing and function of a lot of software from this. CNC Milling
