The mould is to apply CAD/CAM to be mixed the most generally at present one of the most advanced industries. In mould treatment, to make data can apply on CNC Machining machine tool, want to use CAM process designing necessarily. At present more popular CAM software has UG, cimatron, masterCAM, DELCAM PowerMILL, EDGECAM, HZS Space-E. In the development process of UG, CAM is the working associate with the most reliable person that process trade all the time. It offers reliable, accurate cutting tool way not only, more division of programming letting NC can design the most effective machine program in memory follow one's inclinationsly. The findings report of CIMdata points out, EDS UG is regarded as the most formidable competitor in vendor of all CAM software. UG CAM has following a few characteristics: (1) offer reliable, accurate cutting tool way. (2) can machine on curved surface and substance directly. (3) interface of good the person that use, the person that allow to use can depend on the need on the job, custom-built interface of the person that use, can improve exercise efficiency not only, can use effectively at the same time reach the Know-How that saves a company. (4) the treatment way that offers diversity, convenient NC division designs programming all sorts of efficient cutting tool way. (5) provide complete cutting tool library and function of management of treatment parameter library, make can make full use of newly into personnel the experience of senior staff, devise good cutting tool way. (6) offer extensive to use model aftertreatment function, produce each NC to process the NC form with applicable machine tool. UG CAM includes 2 axes to arrive cutting of management of library of cut of 5 axes milling, line, large cutting tool, hypostatic imitate and extensive are used model aftertreatment implement wait for a function. The article will introduce 3 axes milling the application of medium tall cutting on mould treatment. Wait for the tall cutting such as tall cutting to be on mould treatment, basically use at needing cutting tool to suffer below the treatment condition with even force. The tall cutting such as application can finish the of 80% workload in CNC Machining. For example when rough machining, common cutting tool gets power great, because this waits for tall cutting to be able to cut deep way in order to control, cutting tool limitation getting power is inside a limits. In addition, be in in when treatment or finish machining, if increase industry position,too too steep, deep, need extends the case of lengthen edge, because cutting tool is too long, slant when treatment place too big, also often need to use the means that waits for tall cutting to reduce cutting tool to get power. At present machine tool of the most popular high speed cutting, also be the use person that waits for tall cutting. The waits for tall cutting function to provide diversification not only treatment means of UG, allow cutting tool to be able to be in whole treatment process below even condition getting power at the same time the cutting with the fastest, best implementation. It is the character of the tall cutting such as UG below. (1) cutting tool is used it is OK to do not have division of the finite programming that make NC qualitative, clip holds capable person of the function of machine tool of according to treatment, semifinished product means and the consideration to cutting efficiency, freedom chooses the cutting tool such as smooth knife, ball knife, round nose knife, T knife to undertake waiting for tall cutting. On computation, UG uses chooses cutting tool, statified the treatment face computation such as the edge, can produce accurate cutting tool method so. (2) explore Undercut area UG automatically to be able to explore the Undercut area inside size range of pipe bent automatically, automatic computation gives way of first-rate cutting tool. When be being cut with T Dao Xi, if knife handle and treatment range do not occur interference, UG makes the most complete cutting as far as possible. Because use smooth knife cutting, because this is in Undercut area, the cutting tool method that UG produces does not come up against treatment face to be a principle with cutting tool. (3) the tall cutting such as the UG of type of cutting tool method that provides diversification offers double entry cutting, one-way cutting, helix cutting, edge edge cutting to reach multilayer edge edge cutting. Among them multilayer edge edge cutting can offer efficient shag base to machine method, also be the good choice of finish machining of face of deep steep treatment. Machine tool of high speed cutting can use this function to make good treatment way. Multilayer method of 3 cutting tool produces on the each deepness of the cutting tool method of edge edge cutting, the first leaves 3mm of finished product face, the 2nd leaves 1mm of finished product face, the 3rd path criterion treatment is on finished product face. (4) when generation cutting tool suffers the treatment method mould with even force to machine, NC programming division or machine tool operator often to avoid the cutting tool in NC program local get power too big and cause cutting tool the case of severe loss, must lower the feed rate of integral method, affected whole treatment efficiency thereby. UG offers means of diversiform feed rate set to solve this problem. The person that use is OK set cutting tool is local the feed that gets power is led (like cutting of the first knife, the) when corner of method of the cutting tool when move back and forth of cutting tool method. (5) in set of different height area different cutting deepness can keep even semifinished product to be after treatment, do not expend needless handling time again at the same time, UG can offer the person that use to press the appearance character that processes work, the cutting deepness that in different high area set differs. Finishing multilayer when be being machined in edge face, in abrupt area but the cutting deepness with bigger set, in gently area set lesser cutting deepness. (6) the idea that has treatment material and finished product system machines what material reachs finished product put oneself in another's position to run, the person that let use falls in the condition that does not alter CAD model, can undertake waiting for the computation of tall rough machining and finish machining conveniently. Make to the NC program of mould electrode and slide block very convenient. (7) the CAD data that place of the person that have allow to need job of cutting function mould receives, often be the IGES record that upriver place provides. Regular meeting has the state of clearance and jackknife between the curved surface of the CAD model that because this is machined,uses. UG offers allow to differ cutting function, the internal energy of tolerancepublic errand limits of set of the person that using handles the clearance between curved surface and jackknife automatically, produce good cutting tool way thereby. (8) go up in individual treatment curved surface, can the treatment obligate amount with different set is in mould design, as a result of the standard of appearance of finished product geometry, the wall that often needs a definition to differ thick, face combining a model, rely on to defeat face and side of general finished product. For convenient NC division is in programming program of NC of the set on onefold CAD model, the obligate that UG lets NC stylist differ in the set on individual treatment curved surface is measured (value and negative worth) , in order to improve the design efficiency of NC form. (9) offer a variety of entering / the tall cutting such as UG of the means that retreat a knife offers linear, broken line, circular arc to wait for a variety of entering / the means that retreat a knife, will satisfy the need that machines actually. The person that use can be in what different deepness area or treatment area set differ at the same time beforehand bore position and bore deepness. UG can depend on treatment geometry appearance and cutting tool definition when feed, automatic decision by beforehand bore feed or inclined to feed, in order to accord with effective treatment requirement.
