Cimatron E machines medium process designing characteristic in high speed of model of digital camera antrum

02 in industry it is a tall intelligence, efficient one of systems of numerical control process designing that provide security most, from rough machining, leftover semifinished product again rough machining, semifinishing machining, finish machining and horn of automatic Qing Dynasty, whole technological process has perfect high speed to machine strategy. The article auspicious fine in explaining to be machined with the high speed of model of digital camera antrum, the characteristic of cutter track process designing that Cimatron E answers. Graph figure of face of 1 rough machining pursues 1 rough machining builds side elevation of 2 rough machining above all the cubic semifinished product that processes an object, and the part program that agrees with mould face, such systems are when any moment computation cutter track, can consult semifinished product information, assure the accuracy of cutter track, security. Rough machining is used surround thick mill (the treatment method of Rough Spiral) , need not appoint the treatment deepness of apogee and nadir, be based on appearance of initiative semifinished product automatically to press a standard statified, pursue the strategy of a cutting. The in-house and fast height that carry a sword presses increment means and but join of set round horn, light of the method when making sure the machine tool moves quickly is suitable transfer, the machine tool that avoids because of pointed horn generation shakes. Feed means is used optimize mode, deepness helix leaves a sword, between the layer true surround, and set surmounts border / the feed mode of semifinished product (Entry-beyond Boundary/stock Limits) , the system identifies the feed outside open area semifinished product automatically, close area helix feed or diagonal feed, still can set size of the smallest feed additionally, avoid to carry a knife on the head, the cutting that achieves zonule filters. Milling direction divides suitable mill, go against mill beyond, still " mixes mill + arrange mill finally / the means of the " that go against mill, can reduce the circumstance that jumps to suitable mill is used when the knife can assure to be close to the last knife of workpiece again or go against mill already so. Cutting deepness is pressed optimize (Optimized) type, insurable the surplus after each mesa that deepness differs inside card antrum are machined is in book limits inside. Model antrum kind mould, use trochoid (Trochoidal) means, can avoid state of full knife cutting effectively, of bits of benefit Yu Tie eliminate quickly, prolong cutting tool life. Below any circumstances, cutter track corner is automatic round horn transfers, can prevent the urgent bend phenomenon of cutter track contrail, avoid rate loss and machine tool vibration. Additional to all sorts of feed rate optimize very rich also, be like: Rate leaving a sword (Plung Feed) , initiative cut rate (Entyr Feed) , reach corner automatic rate is controlled (Adaptive Feed Control) , still have to finish machining: Pace speed of advance is led (Side Feed) and gadarene cutting rate (Down Feed) . If the cutter track of rough machining pursues 1 - 2 are shown. 2 incomplete expect 2 times when rough machining rough machining, for efficient purify material, adoption cutting tool diameter is opposite for bigger, suffer the effect of cutting tool, model the material of some positions remain of antrum is very much still. The method of 2 rough machining of Cimatron E (Rerough) designs for this just about. The odd semifinished product of before Rerough intelligence identifies one program, need to choose the cutting tool with an opposite less rough machining only, can make way of incomplete makings rough machining automatically. Because of the treatment inside Cimatron parameter can be set into associated and variable form, if cutter spacing is set into "0.

40*tldi" , least dimension leaving a sword is set into "tldi-3*crrd" , among them Tldi represents cutting tool diameter. Wait to still can be called directly from the knife library that has decided beforehand as to rate of athletic parameter, rotate speed, feed, because 2 times this rough machining needs to adjust a few very few parameter only can, other setting basically agrees with Rough Spiral. Be in the turning point of the mould, cutter track step locates blame plane or before create the position that the knife does not have mill to arrive and current Dao Nengxi reachs automatically short-hilted broadsword or the method of many knife, and but reasonable use trochoid treatment, if pursue,3 are shown. Be passed or for many times after program of 2 rough machining, provided the cutting environment with a basic and even surplus for semifinishing machining. Graph 2 times 3 rough machining pursues the finish machining means of 3 semifinishing machining and finish machining Cimatron E abounds method of 4 finish machining diversiform, already high speed machines means to again the tradition machines means, classification is very apparent, be aimed at high speed finish machining for, have the following kinds of very practical treatment methods, be like: Parallel cutting ＋ is abrupt a cutting, three-dimensional surround cutting, etc tall cutting, according to cutting of limitative horn partition, even area can divide parallel to cut again in divisional cutting, helix surrounds cut, three-dimensional annulus is cut etc, abrupt area can divide constant layer to cut again, variable layer is cut, insert cut etc. Be aimed at the characteristic of this record pattern, semifinishing machining can be used three-dimensional surround cutting (the method of 3d Step) , step pitch means is mixed by three-dimensional step pitch the greatest height leaving mark two-way at the same time pilot method, ensured in model the face is abrupt step pitch won't be pulled very widely, the most important is to be able to be pressed guide operating ring of the always that make a plan cuts method figure, avoid method quick underground slope or climb slope, assured the gently sex of method, this is very important to high speed milling. The purpose of finish machining is to rise further model of the face bright and clean degree, depending on cutting of limitative horn partition is a kind of method with high speed the most commonly used mill. Even ministry uses helix to surround commonly cutting, abrupt ministry uses advance and retreat of form of the S between variable layer cutting, layer knife or two-way insert cut (if pursue,4 are shown) method. Can prevent feed trace effectively, decrease jump knife, and transfer R horn area can get ideal result. Graph horn of 5 automatic Qing Dynasty pursues 6 machine tools are felt draft 4 clear part horn of automatic to mixed pattern Qing Dynasty especially important, horn of Cimatron E safety, accurate, reasonable automatic Qing Dynasty can reduce the likelihood that electrode makes greatly. Drawing style clear root (Pencil) does not have limitation to the use of cutting tool, in Z axis direction and but much knife is statified milling. Horn of automatic Qing Dynasty (the odd area of a knife or rudimental semifinished product have partition, to differring area can use different kind taking a knife, be like abrupt ministry etc tall surround knife, the cutting tool way that even ministry cuts by the annulus of edge corner 3D inside extroversion, if the graph is shown 5 times, the method that assured whole process smooth, load is even. Examination of 5 collision interference arrives from rough machining clear part, support the interference inspection of whole process. Definition good clamping apparatus and the length of cutting tool headroom that should use actually, the system can undertake the interference of clamping apparatus is checked automatically, the local cutter track that has interference avoids automatically let. If the length of cutting tool headroom of the definition is more than length of ideal cutting tool, the system can output commendatory optimal knife to grow, offer reference of process designing personnel, make the use circumstance of cutting tool achieves groove. The automatic output with optimal long knife, because be measured artificially,avoided to forbid, and of generation cannot book sexual mistake to happen, had protected hardware equipment. Besides, cimatron E still offers complete machine cutting imitate, if the graph is shown 6 times, be like collision happening, can produce early-warning information, on real significance restrict collision in process designing phase. Graph 7 form technology is only only to program of 6 aftertreatments and automation form technology ends, the NC form that how outputs optimization also is crucial, cimatron E backs all sorts of controller kinds, code can press output of interpolation of linear, circular arc, also can output the form of NURBS curve interpolation that high speed controller has. To mixed pattern process designing, process complex, loaded down with trivial details, program amount is more, cimatron E but fast, accurate output form craft sheet automatically, if the graph is shown 7 times, need not a ground fills in artificially, avoid needless elementary mistake to happen, rose to machine the security measure of the process further. The place on put together is narrated, cimatron machines the idea with distinctive domain in the mould, make Cimatron has become current CNC Machining, especially one of first selection software that high speed machines, the processing technique of Cimatron still is continueing, apace develops, hold the world's lead position. Process designing of milling of Cimatron high speed had received wide application in home, if Haierji is round,pattern production limited company, beautiful mould makes electron of center, rich harbor (Dongguan) limited company, Zhuhai and wait into communication equipment limited company.
