In actual production, the gear form of high quality exceeds repair forcedly grind annulus a lot of advantages have on function: Manufacturing efficiency is tall: Long form emery wheel or cutting tool and treatment workpiece are alternately on same table machine tool undertake, can rapid precision complex model face answer mirrors emery wheel or cutting tool apparently; service life is long: Long grind annulus can carry its dimension and form for a long time precision, wear extent minimum, long grind a frequency to be able to amount to above 1000 times, work product quality is stable, operation of long form of cost low; is handy. Long grind annulus put the work in the machine tool locally, undertake be repairinged randomly grinding emery wheel or cutting tool, just like processes a work same. Long form fare is low: Long form operation does not require equipment of special machine tool, level of operation staff technology can be reduced, long form time is short, precision of workpiece of treatment of cost low; is tall: Because repair form operation and treatment workpiece to be the same as machine undertake, all sorts of errors of machining complex already were included in building form operation, machine workpiece is long form to go against a process, accordingly, workpiece treatment precision is tall. Milling machine main shaft every rotate 1 week ordinal generation is similar to 3 tooth 1 times the torque of sinusoid is undee. Can think, milling twists the existence in be apart from weaveform two kinds of basic and periodic signal: Milling cutter every rotate to form cycle of milling cutter roll 1 week (its are worth the rotational and periodic) that is equal to main shaft, undee correspondence orders from beginning to end between two tine the interval between forms cycle of milling of an odd tine, a milling cutter turns cycle includes M (M states mill tooth is counted) odd tine milling is periodic. To much blade milling cutter, frequency of odd tine milling always is more than frequency of milling cutter roll. If cutting process is ideal and smooth word, around the weaveform of milling torque is identical between cycle of roll of two milling cutter. Dan Xianglin differ however phasing is the same as the milling torque weaveform between cycle of milling of 2 odd tine, this is quality of the geometrical angle because of every tooth, point somewhat difference, still be made basically as a result of tooth and mounting error is caused prejudicial the change of the cutting dosage that cause. Still existing in cutting process additionally a lot of Zhen Yuan, actually so milling still is including the part of other frequency in torque signal. CNC Milling
