In metallic cutting process, choose very high cutting rate, not be the only method that improves treatment efficiency certainly. Do not ignore the big feed below medium cutting speed to machine plan, this is the conclusion that reachs by many cutting practice. Be based on this one new knowledge, to get used to the rapid development of automobile manufacturing industry and aviation manufacturing industry the situation is mixed the market need that develops new product ceaselessly, development is a brand-new technology recently -- namely efficient processing technique. They think, normally cutting of so called high speed, choose very high cutting rate and very low feed and very small cutting deepness to undertake cutting. A lot of program of this kind of cutting is subsistent problems, among them the biggest question is: Main purpose is the high speed cutting that produces efficiency with Yudigaosheng, did not improve manufacturing efficiency actually. It asks the machine tool issues cutting in rotate speed of tall main shaft, but will raise cutting rate to increase rotate speed of machine tool main shaft, often reduce cutting deepness in order to reduce feed ﹑ to be cost. Excision rate is very so low, manufacturing efficiency is not tall. Of course, the main shaft power of this opportunity bed is OK very small. The finish machining that this reach the part with exterior integrality very high demand to surface roughness of those dimension precision, surface (requirement spare parts is changeless form, the cutting power that produces in cutting consequently wants small the treatment that waits for a series of extremely slashing conditions to fall) , it is very advantageous truly. What develop research by Professor PhilippAndrae is efficient processing technique, what machine the quality of the spare parts and manufacturing efficiency from inside beginning to emphasize cutting machining is collective more substantially rise. This research acceded high speed cutting can reduce cutting force ﹑ to raise the characteristic such as precision of treatment spare parts and exterior quality. Emphasize set out from the purpose that improves manufacturing efficiency greatly (the excision in raising rough machining is led) , undertook many cutting experiment studies. Solved a lot of technology difficult problem from the union of theory and practice. Make efficient cutting technology development considered to obtain great progress. Efficient the key of processing technique depends on: Adopted choose or new design goes out have enough machine tool main shaft rotate speed and relatively the Gao Gang of high power ﹑ of the capacity that the earth delivers pitching moment sexual machine tool, undertake high-power cutting; Choose material of current and best advanced cutting tool; Choose the advanced cutting tool collet that suits cutting of high-power of high speed ﹑; Adopt the technical measure such as the cutting parameter with the special treatment means that provides a color alone and logical choice. Not only such, on the foundation that experiments in a large number of cutting, study the new breakthrough that go up to cutting theory, also be the critical factor that makes achievement of this scientific research scores a success. What cutting theory considers to go up is new the amazedly discovery in breaking through them to study from many cutting experiment: In high-power efficient the kinetic condition in cutting, the cutting performance that affecting cutting tool extremely advantageously and wear away form. Among them: Kinetic condition basically is the contact that shows the cutty between workpiece and cutting tool is extremely osculatory time, frequent frequency, extremely the cutting temperature of great disparity changes, and in the cutting in high-power, relatively of earth influence cutting tool and workpiece contact length (of cutting around) the very small ply that cut bits is compared etc. These in happening efficient the kinetic condition in treatment, make cutting area produces very high cutting temperature, make the workpiece material bate of cutting area, the addle of exterior surface roughness after making the spare parts is machined. But reduced cutting force however, reduced cutting tool wear away (make contradiction of cutting tool tatty falls right now for very minor position) . Be in especially nonferrous metal material for example in the efficient milling of aluminium alloy spare parts, these phenomena are reflected more apparently. It can make the cutting temperature of cutting area becomes tall, make workpiece bate, cutting is so light. Of course, this does not include to must adopt kinetic requirement the milling treatment of the plane of the small feed with the very great difficulty on very poor, technology and round dambered surface. Because workpiece bate is out of shape,such treatment can be caused the treatment dimension precision that cause is not advanced a series of problems. But, this a series of technical difficult problem, can be in efficient the finish machining phase in treatment gives solve. Above conclusion and the conclusion that high speed cutting studies to reach are fundamental be identical. But this is to be in what test and verify gets below deepness of feed ﹑ big cutting and condition of medium cutting speed greatly, it is the new breakthrough in cutting theory respect undoubtedly. This one theory makes a base, just make efficient processing technique considers to score a success. Choose or new design gives the machine tool that can have high-power cutting to want to improve manufacturing efficiency, must raise excision rate. By cutting principle knowable, the excision quantity in metallic cutting and feed of cutting speed ﹑ and cutting deepness are having close relationship. Accept the restriction with kinetic cutting, in general cutting, cutting deepness cannot choose too big, efficient cutting is not exceptional also. But efficient treatment can choose big feed (in dividing the cutting in stone's throw, because accept the restriction of acceleration, outside choosing small feed to machine only) with proper big cutting deepness undertakes machining. Repass chooses as far as possible tall and not be to choose very high cutting rate to try to cooperate, also can achieve tall excision rate. But must be chosen or new design goes out have enough machine tool main shaft rotate speed and relatively the Gao Gang of high power ﹑ of the capacity that the earth delivers pitching moment sexual machine tool, ability undertakes high-power cutting. At present the is used at high-power cutting machine tool of new design already can be in of 24000r/min (design for the machine tool) below condition of medium cutting speed, undertake to aluminium alloy spare parts the thick mill of high-power is machined. In cutting of general high speed, the high-power that the machine tool offers comes true through restricting main shaft rotate speed normally. Output power when the machine tool changeless, main shaft rotate speed increases, when excision rate falls, its reason is: As a result of the addition of main shaft rotate speed, enhanced the power that place of main shaft idling consumes. And reduce feed (increased the osculatory time between cutting tool and workpiece) , increased the attrition power between cutting tool and workpiece instead. Be in so efficient in the rough machining of cutting, choose rotate speed of very high machine tool main shaft, it is useless actually. Even root Ju is about to machine the cutting condition such as material of cutting tool of hardware data ﹑ and dimension size, have serious choice to the cutting parameter such as cutting speed, feed speed and cutting deepness. For example: When choosing small diameter cutting tool to machine aluminium alloy spare parts, can choose to come high the main shaft rotate speed of 100000r/min above and treatment of low feed rate. And the other data that processes big diameter, choose a bit low main shaft rotate speed relatively. Be in efficient in treatment, need to choose the cutting speed of 18000r/min and very big feed career only, can make excision rate achieves 5000cm³/mm. This shows, be in efficient in treatment, root Ju is about to machine the cutting condition such as hardware data, choose choose cutting parameter reasonably, also be efficient one of assurance that machine success choose material of advanced cutting tool. From efficient cutting principle respect will analyse, be in efficient in cutting process, action is in the size of the cutting force on cutting cutting tool, depend on the discretion of the cutting temperature inside cutting area. In the meantime, the effect of the effect that cutting tool of the cutting in cutting suffers centrifugal force is quite serious also, because very small centrifugal force can make,cutting system produces intense vibration. So, the cutting tool material that must choose tall tenacity of tall hardness ﹑ and benefit can assure the geometrical appearance of the cutting tool of knife head intensity again at the same time at reducing cutting force. For example, choice hard alloy (besmear Fu and blame besmear Fu) , material of cermet, pottery and porcelain, get together brilliant diamond (PCD) nitrogen of He Jujing cubic metre changes boron (PCBN) wait for best cutting tool material; Respect of appearance of cutting tool geometry, all use the geometrical figure of the cutting cutting tool that optimized via the computer, and with suit at high speed efficient the cutting tool collet of cutting closes suitably, in the meantime, must undertake before use high accuracy is balanced. Choose advanced cutting tool collet to be in efficient in treatment, most the cutting tool collet that often uses is hydraulic pressure can go up type collet and heat go up cold shrink type collet. It is good that latter has tigidity with the capacity that can deliver great moment of force. But existence replaces speed to be mixed slow adaptability (flexible) poor defect. And hydraulic pressure can go up type collet is contrary, assemble and unassemble convenient and fast, but deliver pitching moment small, can use at what needing the nonferrous metal with not large clamping force only, for example of spare parts of small-sized aluminium alloy efficient finish machining. Use special treatment method to be sufficient play efficient of treatment efficient advantage, adopt method of a few special treatment, also be the important segment that makes excision rate rises. For example, this university is in experiment research, the choice is on the horizontal machining center of high power (because it has capacity of crude automatic platoon bits relative to vertical machining center) , use much blade get together brilliant diamond (PCD) or besmear Fu diamond makes (broach and reamer) the aperture inside high accuracy of treatment of cutting tool of treatment of complex formula aperture; Manufacture efficiency to rise, reduce manufacturing cost, much blade of type of use machine clip gets together nitrogen of brilliant cubic metre changes boron (PCBN) establish milling cutter to undertake high accuracy inside Kong Jia is versed in (execute thick ﹑ finish machining through programme controll, undertake inside the adjustment that hole size machines) . For example, in the treatment on spare parts of aluminium alloy casing 6 different diameters, limits is the aperture of 12mm~32mm, normally treatment method is to use 6 6 broach, reamer to have thick precision work to aperture at least. And now, need to choose a thick milling cutter and an essence milling cutter to undertake only efficient treatment, can make sure the quality that machines high accuracy asks, time of managing cutting 25% ; Additional, choose Fu of much blade besmear hard alloy thick milling cutter, undertake the high-power milling of surplus of big planar purify wait to have the special treatment plan of the style alone, obtained favorable treatment result. Current, this research still is in begin phase, and because be a kind of technology complex involve extensive systematic project, still require the cooperation of many sided and cooperation, undertake much research works. At present majority still can be used at needing large quantities of capacities only efficient the aviation of treatment and car use the nonferrous metal part such as aluminium alloy. But the market competition capacity that can increase production business admirably as a result of it, have very good market perspective, consequently inevitable meeting gets rapid development. A lot of industrialist that have strategic eye, devote into at efficient the development research of processing technique. Introduce according to newest data, fadal company comes true to help an user better efficient treatment, undertook many experiment considers to work, increased to rotate on a variety of vertical machining center that design production in them workbench, automatic cooling system, double arm changes a knife automatically system and cut bits to transmit a system automatically to wait, in order to improves manufacturing efficiency better, increased market competition capacity greatly.
