A when 5 axes machine linkage main feature uses short cutting tool in cutting process namely, reduce cutting tool significantly thereby suffer force to bend, improve treatment surface quality, prevent what do poorly done work over again reduced electrode in great quantities to apply. The people in 5 axes process designing often pays close attention to pair of interference and collision very detect reach evasive, but to CAM system character, only these are far insufficient, system must mature to the machine tool kinematic the limitative condition with geometry, this is a strong challenge to CAM system. 5 axes machine the application of 5 axes and problem to already matured with each passing day in the application of aviation and shipping domain, but the application that processes a domain in the mould just just began. 5 axes treatment is divided normally machine to secure 5 shafts (also be called 3+2 axis is machined) with linkage 5 axes are machined. Secure main shaft of the machine tool when 5 axes are machined to will be spent with certain banking angle, use shorter cutting tool to undertake high speed cutting, promote cutting efficiency already so, rose to machine precision again. It is OK to use this kind of method through set many treatment angle is finished a series of area treatment, the precision that needs to install clip to repeat fixed position in order to avoid only is short of break, save time of transhipment of through cargo in great quantities, the electrode that can reduce follow-up discharge to machine at the same time uses a measure. Of much angle secure 5 axes to machine existence two serious problems: The treatment cutter track that is different point of view must overlap, handling time can be lengthened, jackknife area also produces the trace that receive a knife surely surely, the surface machines quality to cannot get very good assurance. 2 be a series of angle definition and process designing are very trival and complex, process designing personnel needs to spend a large number of time and the risk that make mistake is increased. 5 axes treatment solved linkage to secure the issue that 5 axes machine, although use very short cutting tool, also won't cause the repetition of treatment angle. But so far the application that 5 axes process in the mould returns linkage presence is constant limitation, basically reflect in two respects: It is to agree with strategy of 5 axes treatment compares the linkage that the mould machines little, because 5 axes machine linkage to basically applied at the product such as aerospace equipment in the past,this is, the treatment of the spare parts, and the requirement that these treatment strategy satisfy a mould to machine hard; 2 it is work out linkage the skill with the program very high need of 5 axes, make accurate judgement and intervention in the ability on rich experience base only. This and difference of 3 axes process designing are very big, home's corresponding technology qualified personnel also very deficient. Graph 1 same cutter track can move fluently on machine tool of Auerbach IA 5, but change DMC 75V, rise along perpendicular wall when orbit span end face, when moving downward next, the machine tool can happen call the police what 5 axes machine is brand-new 5 axes machine tool and system of 5 axes CAM are in plan the actual application of mould production domain is an advanced technique that development of the last few years rises. As the whole world famous full automatic CAM software, workNC put forward first in mould production domain brand-new extremely practical strong 5 axes machine a solution: WorkNC Auto5. This kind of solution can abound sort simply agree with the 3 rods that the mould processes and 3+2 axis cutter track are automatic translate into linkage 5 axes cutter track, detect automatically collision and the limitative condition that consider the athletic geometry of the machine tool. WorkNC has the rich 3 rods that process in the light of the mould and the treatment strategy that secure 5 shafts, its outstanding process designing efficiency and operation function already made a domain get iteration proof in the mould. So whether use these dominant positions linkage 5 axis? The domain was made be rolled out first in the mould through company of old Sescoi of research and development brand-new extremely practical 5 axes machine strong pattern plan, this is the Auto5 of WorkNC. Personnel of process designing of use WorkNC Auto5 but automatic translate into does not have the simple 3 axes any WorkNC or the cutter track that secure 5 shafts collision, the linkage that at the same time full toe decides machine tool geometry and kinematic tie 5 axis cutter track. In addition, 5 axis cutter track undertakes the linkage after be being changed through installing parameter to still can be opposite flowing processing, make more accord with effective treatment demand, assure to machine character thereby. A characteristic of machine tool of axis of graph 2 5, namely one swings axial definition is in B9.

5, c0 and definition are in B-9.

5, cutting tool is opposite between C+180 or C-180 the cutting position at workpiece is WorkNC Auto5 of same module of WorkNC Auto5 function include two functions module: 3to5axis module and 5tomachine module. 3to5axis module can mix 3 axes automatically the linkage of politic translate into that secures the cutter track of 5 axes to press make choice of 5 axes cutter track. This module detects and evasive cutting tool reachs the collision of hilt. This changes a course is the geometry that does not depend on a machine tool and athletic feature. 5tomachine module is according to the linkage that the machine tool of make choice of outputs to 3to5axis 5 axes cutter track undertakes be handlinged automatically, detect and the collision of evasive machine tool, make this cutter track satisfies the geometry of machine tool of make choice of and kinematic tie requirement. WorkNC Auto5 solved a standard ably the limitation that 5 axes process strategy application, extended linkage greatly what 5 axes treatment machines a domain in the mould is practical, and its inheritance of the 3 axes process designing of WorkNC mix efficiently, automatically simple process designing concept, the program personnel that makes have masters linkage quickly the advanced technique of process designing of 5 axes treatment turns into likelihood. Graph 3 WorkNC Auto5 can have communicated a definition line of drive of a periphery, come to those who control cutting tool axis swing crucial technology of angle NextpageWorkNC Auto5 uses linkage 5 axes machine mould antrum or component has a lot of advantages related its, but on software level all through the ages of process designing personnel is facing 4 crucial problems, and these problems restricted 5 axes to machine what create a field in the mould to popularize application greatly. Be aimed at these problems, workNC Auto5 offerred corresponding solution, make if 3 axes process designing is euqally simple and relaxed,multifarious 5 axes process designing creates a field in the mould. 1.

The security security problem that 5 axes machine linkage basically shows the machine tool is machining the collision of the main shaft in athletic process and workpiece or machine tool mesa and interference. As a result of linkage the space of course of 5 axes knife runs orbit to hold intuitionisticly hard, this also makes personnel of process designing of major numerical control faces 5 axes machine tool " flinch " . Build be opposite appearance of geometry of 5 axes machine tool and machine tool are departmental mutual between on the foundation of the exact definition that collision concerns. Through software compositive collision interference detects the function comes personnel of how-to process designing make due judgement and operation, the area that collides in designation for instance adjusts the axial direction of cutting tool axis, make can avoid let collide. If omited the modification of collision area, so WorkNC Auto5 will delete corresponding cutter track automatically, in order to make sure whole treatment course is right 5 axes machine tool, relevant component, reach the absolute safety that processes work. The user interface of graph 4WorkNC Auto5 2.

The security that machine tool geometry and linkage of kinematic limitation requirement consider to machine merely in 5 axes process designing is insufficient. In linkage actually 5 axes are machined in, rotor and swing problem of the axis exceeding Cheng far over collision. So, the cutter track of 5 axes must want linkage accord with machine tool geometry and kinematic limitative condition. The majority exceeding Cheng that 5 axes linkage machines results from the rotor on machine tool structure and swing angle limitation of the axis, the machine tool that swings to main shaft additionally, swung when main shaft 90, the greatest distance that it compares designation on axis of X, Y, Z wants a lot of smaller, this thing often also happens X, Y, Z Cheng exceeds on the axis. These exceed Cheng to need to be in process designing when examine immediately, adjust workpiece to put the position through software interior, increase retrorse circumgyrate action or avoid some stopping not to answer through changing treatment craft to come machine. The settlement with the 5tomachine OK and very good module of WorkNC Auto5 this problem: Those who need a specification is a characteristic of 5 axes machine tool, namely one swings axial definition is in B9.

5, c0 and definition are in B-9.

5, cutting tool is opposite between C+180 or C-180 the cutting position at workpiece is same. So complex problem is having handling in the aftertreatment sometimes, and WorkNC Auto5 is in the computational process of 5tomachine can solve automatically. WorkNC builds the meeting in modular process to define the journey of each axis to restrict parameter in the machine tool, the form that takes place to choose a machine tool and journey limitation data are read when computation, automatic apace cipher out and the reasonable and safe cutter track with machine tool corresponding parameter. 3.

Treatment character is in aviation industry, in the light of linkage of large structural member 5 axes treatment can satisfy cutting tool cardinal principle along curved surface law to treatment. But the character of the detail that the more that goes after in mould treatment is a mould and treatment, the linkage is the commonnest law in 5 axes treatment is used to will be just the opposite to what one wished to treatment strategy below this kind of circumstance. WorkNC Auto5 can have communicated a definition line of drive of a periphery, come to those who control cutting tool axis swing angle. Cutting tool axis is vertical from beginning to end in machining a process surround at this drive line whole workpiece cutting, reduced C axis to cave inside each greatly a places athletic place to cause cutting loss of efficiency with frequent area, raised workpiece surface to machine character. 4.

Rich knife course is politic now, the mould machines medium linkage 5 axes machine more returning to just be applied at machining outline, reticle and the simple treatment that sweep an area. Politic without rich and effective knife course, already became the bottleneck that 5 axes technology is in cloggy linkage to be popularized in mould treatment and apply. The occurrence of WorkNC Auto5 broke this bottleneck. Because WorkNC is originally very mature automatic software of 3 axes process designing, the course of faces mould treatment 3 axes knife that has more than 40 kinds is politic, and the course of 3 axes knife of Auto5 changes linkage automatically the technology of course of 5 axes knife applies to course of all 3 axes knife politic, offer mode of 9 kinds of changeover. This makes change into the linkage that can be used at the mould to machine through WorkNC Auto5 mode of course of 5 axes knife amounts to 360 kinds of above. 5.

The efficiency of the maneuverability process designing of software depends on greatly the maneuverability of process designing software. Traditional linkage technology of 5 axes process designing is very trival, the element that process designing personnel needs to consider is overmuch. What contrast to it is the operation platform that WorkNC Auto5 provided one individual sex to change, mix with the concept of innovation distinctive algorithmic and perfect union rises. Process designing personnel should have operated the interface of 3 axes process designing of WorkNC only, through clicking a few additional pushbutton and option can weave the cutter track that gives the 5 axes linkage that accords with mould craft requirement. In recent years, high speed milling is applied extensively at mould cutting treatment, shortened greatly the production of the mould is periodic, reduced a mould to produce cost, also machined character to bring qualitative promotion to the mould. So what is the next technology heat that mould cutting machines? Will be 5 axes without doubt the application of processing technique. Rise ceaselessly as what price of sex of 5 axes machine tool compares, the 5 axes treatment of the mould also will gain ground more and more. This will machine a domain to initiate a technology to change again in the mould, lead a mould to machine course of study to answer the market environment that globalization competes. Of WorkNC Auto5 brand-new mould concept of 5 axes process designing, also will be in this development that CAM software leads the technology in changing. CNC Milling
