The article will discuss the reason that relies on 5 axes treatment to reach its to use range; The politic thought that 5 axes machine and the issue that need a consideration; And of cutting tool method optimize. In mould treatment, applying 5 axes to machine politic a few main good points is: Shorten handling time, reduce handiwork burnish and improve exterior quality. From commercial angle consideration, the treatment quality that it can improve a mould, shorten delivery time, and reduce workpiece substantially debug setting error, all all these will be helpful for raising the manufacturing profit margin of the enterprise. 5 axes treatment already had very old application history in aviation industry, but till the last few years, mould production industry just is shown to this kind of process instrumentation " interest " . The main good point that 5 axes machine is the handling time that can reduce complex part, because workpiece needs shift only,trial assembly gets stuck. Its another advantage is, can use shorter cutting tool, can raise treatment precision further thereby. Graph the 1 5 axes treatment that uses 5 axes treatment to be able to make angle of a first-rate maintains to be able to locate between cutting tool and mould surface is in certain CAM software, early had fixed position 5 axes are machined (call 3+2 treatment again) function. When using this kind of technology, the 4th with the 5th treatment the axis is in buy of dislocation coming back, its treatment is carried out by operation of a group of 3 axes. Besides, certain CAM software can provide successive 5 axes treatment, this can let an user establish method of continuous 5 axes cutting tool on complex surface, substance and triangulation model. Cutting tool method passes comprehensive inspection, supportable a series of treatment strategy and all sorts of cutting tool. The advantage that locates 5 axes machine locates the advantage of 5 axes treatment includes: Can use shorter cutting tool effectively, reduce the outspread length of cutting tool, accelerate cutting rate, prolong cutting tool service life, raise treatment precision, pass simply found a series of directional job plane improves exterior quality. And, use 5 axes treatment, workpiece needs very few tone trial assembly to block a time only, thereby spare time, because debug the error that the place that hold card causes for many times,decrease, raise the utilization rate of the machine tool greatly. The process designing that 5 axes machine does not resemble sounding so difficult. It can pass certain CAM software, find a few simple and practical process designing methods. These software packages can make high speed processing technique receives very good application, in order to get taller cost effectiveness. Experienced user can establish model, the program that establishs for future is managing time, reduced an error at the same time, and can be on the computer undertake imitate to whole craft, appear in order to avoid in workshop treatment mistake. When preparation applies 5 axes to machine, the user may need to adjust the strategy of system of tool clamping apparatus, debug the spare parts character that the largest amount is close to in the process that hold card in 5 axes as far as possible. Generally speaking, the workpiece clamping apparatus that uses a level cannot be close to the many flank of workpiece apparently. Orgnaization of clamp of device of 5 axes clamping apparatus, chuck and magnetic chuck can compare appropriative to make cutting tool freely adjacent need the part of treatment. Successive the advantage that 5 axes machine is to be able to cancel to blend a route, can make appropriate cutting tool maintains continuously treatment moves on exterior direction, this will be helpful for improving exterior quality and the service life that prolong cutting tool. Anyhow, frequency taking a knife decreases, treatment cycle shortens and one-time debug the advantage such as the setting, be helpful for spare time, reduce setting sum of errors to be close to bottom to cut a margin better. Generally speaking, the advantage that 5 axes machine still includes to improve the use efficiency of the machine tool, should use a machine tool to be able to undertake 3 axes HSM only namely treatment, fixed position is 5 axes treatment, successive 5 axes are machined and 5 axes are gotten cut treatment and more and other treatment. Generally speaking, each reference axis of these machine tools has rapidder journey rate and higher main shaft rotate speed. The volume that processes a machine tool plus 5 axes is lesser, rigid taller, improved the treatment result of the machine tool further thereby. However, as the ceaseless development of these elements, the cost that can discover 5 axes machine craft really is rising sharply. Because machine the applied circumstance in special market to lack understanding to 5 axes,this is normally. Once can understand in the round,be in when the workshop when where can score gain, so this kind of controversy can disappear very quickly. But must remember well: High speed treatment and the technique that 5 axes process backside will make these methods are improved further, and open up gives more extensive application territory. These progress of technical respect may be compared in development initial stage costly, but the bigger advantage that waits for field place system to come out now in cutting tool service life, work efficiency and operation expenses will offset these primary charge. Treatment of axis of graph 2 5 can acquire better exterior quality, the choice of the treatment that because this can raise the treatment quality of the mould to machine strategy,the applied limits that 5 axes machine includes pair of reinforcement, round horn, deeper model antrum or model the treatment of core, and the treatment operation of this kind of spare parts such as surface of shallow water wing. 5 axes treatment also can make milling cutter of round head chamfer machines spare parts surface with more significant position. Broaching treatment, undercut treatment, steep wall treatment is gotten with 5 axes cutting treatment all is play the auspicious opportunity of advantage of 5 axes treatment. Use 5 rods processing technique will raise craft level to be able to be adopted a series of politic, the circumstance that the automatic consideration that includes to adopt position of appearance of a curve, a dot, outline, cutting tool among them and examination conflict each other on method of all cutting tool. Certain CAM software also can support the cutting tool design of whole set. Other rough machining strategy include to be nodded from begin, this means cutting tool is such calibration: Axes is nodded specificly through, make cutting end points and this photograph detached. Be aimed at cutting tool of calibration of one linear function, what such axes can set through is linear, and cutting end points to this linear. These two kinds of methods allow his to be close to 3 axes to machine the area that cannot reach, perhaps offer better cutting condition. Graph 3 use 5 axes treatment to be able to compare easily treatment to produce appearance of complex tire mould drive the meaning of 5 axes is projectile direction and cutting tool direction decide by drive surface. This kind of characteristic admitted an onefold drive surface, but this is spare parts of a many surface, it assured the overall protection of half-and-half gouge. Method of 5 axes cutting tool can encounter a such problems normally: When cutting tool and the condition that machine the surface to keep normal, cutting tool may appear ramshackle circumstance, this kind of circumstance may bring about generation not the exterior quality of beautiful. If can use a simplifying referenced face, can solve this problem, remove this kind of effect. The treatment that cut bits is one uses the flank cutting processing technique that establishs milling cutter. Machining while, advance along the surface of the spare parts, resemble the sidewall of cone-shaped reinforcement for example. If according to draw a frame round of a group of lines reference is worth, also can make a similar cutting tool way. The cutting tool of all sorts of types, include cone-shaped cutting tool to be able to be used at cutting bits treatment. The good point that line draw a frame round cuts bits to machine is, below certain circumstance, it can raise the surface to cut the quality that bits machines. Always inside exterior structure is poorer, or the brim matchs not quite perfect place, using method of this kind of treatment is more appropriate. The position that the meaning that direct curve processes 5 rods is cutting tool is controlled by onefold curve, move with assuring what control cutting tool route in the round. This kind of advantage that machines a method is: Can eliminate cutting tool and the possibility that the machine tool collides, because can control the dynamic character of the machine tool better, because this can improve exterior quality. Test and verify of method of completely compositive cutting tool can offer a kind of complete collision to check an instrument. The test and verify that the machine tool moves and imitate can detect and show potential collision case, and axial moves, allow to use handiwork to be driven gently on any axes, with adjusting this kind moves. Choose to be able to provide the CAM software that prevents collision automatically again next, the machine tool damages and cause significant pecuniary loss in order to prevent. Treatment of axis of graph 4 5 allows those who use method of shorter cutting tool cutting tool to optimize CAM software to still can be an user to provide a kind of means that optimizes cutting tool method. Umbriferous law can highlight rainbow treatment is ordinal, and the retrorse movement that colorific change can show an axis. Foresight is visible the system will lead the geometrical appearance of cutting tool, speed and feed consider inside. Use new CAM systems analysis most advanced character, the user can see the real moving progress of cutting tool and effect, the influence of rate of accurate ground indication feed and speed to spare parts surface, bright and clean degree is worth the surface before can forecasting effective treatment. Of the dot distributing afresh the effective means that provided a kind to reduce handling time. In a recent example, the 5 axes that speed of a feed is 7500mm/min machining center, because used a dot to distributing afresh, because the tolerancepublic errand data of this and standard is compared, it can make machine cycle to shorten 39% . The member that can let process designing controls the smoothness of cutting tool method freely, and nod each on cutting tool distributing, achieved above thereby these results. Use correct CAM software process designing to undertake 5 axes treatment can be an user to offer an economic strategy, shorten treatment cycle, reduce tone number of trial assembly card and improve exterior quality, can prolong cutting tool service life, using traditional 3 axes to machine is impossible to achieve afore-mentioned results.
