All concern with aiguille, ? Aiguille, the linear apophysis line of method of those edge cutting tool, it is the can show an issue surface feature that after undertaking with circular arc cutting tool milling is machined, leaves. In high speed treatment, the distance between the height of aiguille and aiguille reacted process designing member politic target. Same, aiguille or the key of the new development in understanding method of high speed milling, the StarragHeckert(that for example comes from Swiss Rorschach Sidalagehaikete) the P milling law of the company. P milling is this company is such as of 5 coordinate machining center machine tool of horizontal of its SX, HX and STC series the patent technology that wait and develops. Say according to developer, the main feature of this new-style milling method is OK the cutting tool position that computation optimizes milling cutter to locate on work surface. P milling uses a kind answer curved surface cutting tool, the cutting tool that has annular geometry figure in point of its cutting blade namely (in fact, this kind answer the) of mathematical theory foundation that appearance of curved surface geometry is this method. In P milling law, tilt cutting tool proper point of view, can machine a the widest distance between aiguille thereby, maintain at the same time beforehand the aiguille height of set, because this is OK,reduce handling time according to treatment parameter or improve exterior surface roughness. Of milling cutter relatively directional through a kind of special algorithm in CAM software derivation comes out. This algorithm is calculated a certain number of axial vector, choose a best according to workpiece geometry appearance and public errand. Say according to developer, of cutting tool directional optimal from beginning to end ground and surface are comfortable match, make guide horn changes according to need. Be this distinguish P milling and Sturz milling come - latter is in 5 axes cutting tool is directional in the clearance part that uses to unite from beginning to end and without giving thought to geometrical appearance how. Sturz milling itself is at 20 centuries by StarragHeckert company 80 time introduce North America (be called in the United States in those days) of rigid machine tool, the company says, this can show it is innovating milling technology respect to have very long experience with software. This company discovered a lot of value of method of this kind of milling. When applying in rough machining, it acts as a kind of effective rough machining craft. When applying in finish machining, p milling or can reduce handling time, implementation and the same appearance quality that can acquire with Sturz milling, or can have acquired much exterior quality with same handling time. The biggest width between aiguille of have the aid of, shortened through reducing the treatment number of a need milling time. photograph comparing, use same treatment number but what reduce aiguille height to reduce or eliminated a hand to move polishing is necessary, can preserve the geometrical appearance after treatment. This company gave out the example of respect of lamina of a turbine, the test that uses P milling to undertake among them shows this method can use treatment of 5 coordinate machine tool to go out need not the exterior surface roughness that farther hand moves polishing. Had prepared the installation in wanting to be machined in turbine component this kind of machine tool, do not use further treatment at the same time. On the other hand, in showing to the test that place of a mould has P milling machines the appearance that give, use a 20mm(0. 787 inches) after milling cutter is machined, aiguille distance is 6mm(0.
236 inches of) , and parallel case is 0.
2mm(0.
008 inches of) . Below this kind of circumstance, handling time shortens about 35% . Accordingly, p milling is recommended to be used at treatment to have the work of relatively slow, invariant curve, such as mould, crust and outer garment. CNC Milling
