Cut law milling (or call comprehensive feed milling or insert into law milling, interpret is noted) the means that provides deep indentation of milling of a kind of tall productivity, do not need high speed treatment. A datedder machining center, likelihood speed is inferior, but it is good to want machine tool tigidity only, it grows cutting tool through using likely, with a series of jackknife is cut, thick cut material, achieve high metallic excision rate. These enter cutting is sharp Z axis movement cuts work, be similar to auger cut motion. Certain milling cutter is become to be used at method of this kind of cutting by the design, efficiency is very tall, according to CAD/CAM development business Delcam introduces, of certain type cut a law to use cutting of this kind of method, efficiency is taller. Delcam explains its idea that enters law milling about cutting, the concerned aviation that holds in French Paris recently as this company and spaceflight machine the one part of the conference. This company says, with cut law milling, very few person thinks of cutting tool method. Most user apt feels linear, parallel platoon is cut enough. "Grating " model cut: Initiative Kong Jia is versed in (or with auger cut) later, first time plunge milling and this aperture jackknife (cut every time must overlap with the mouth, so that discharge bits) . Next, cut the 2nd times overlap with first time, etc, cut with linear platoon, the length of moving indentation. Be over in mill such the first later, cutting tool is ascended, mill the 2nd, with the first jackknife, etc. This method produces the first problem, delcam says. Machine with this method " groove " leave very little space to discharge bits, cut bits to be pressed too cheek by jowl it seems that consequently. Additional, cut every time along this jackknife nothing more than be foregoing enter cutting, consequently material piles ceaselessly tall. Another problem is, a series of straight platoon may not be the appearance that suits indentation well. To those models in aviation industry, grotesque spare parts, especially such. The appearance that if cut,enters cannot suit the appearance of indentation, so, "One by one erect " bequeath material may stay in indentation brim all round. This company says, a kind of better method is to press continue of circular arc appearance to be cut. Start remains an initiative aperture, first time jackknife is cut with it. But next, the 2nd times jackknife is cut can cut with first time with initiative aperture, etc, the following cut according to the circular arc around initiative aperture. Next, of the 2nd series it is OK to be cut will be cut according to the big circular arc of the contrail of the area that cuts around this, etc. Typical, linear model a when cut clear advantage is process designing easy. Be at a loss for words point-blank cut easier generation software. More complex form is consistent the arc of series, must by process designing member come scale. Undertake milling according to this kind of appearance, really productivity and efficiency are taller, this company says, but process designing should expend some of time more really. Have the CNC of this characteristic, move same a spare parts for many times, through every time try to improve, can get treatment of this spare parts better, faster. To control vibration, manufacturer of this machine tool says, linear electromotor and ball guide screw are compared, choose which, where is unlike electromotor thrust augmentation is so important. A few CNC are boastful have this capacity. Below what circumstance does the machine tool just suit to have this property? Of the arc along a kind of type cut law milling, the machine tool that can feel slower is efficient milling indentation, provide better means. CNC MillingCNC Machining
