The fast high accuracy of knife of end panel of external diameter of numerical control lathe is right knife law

The method that traditional lathe basically cuts work through trying is right knife, namely turning workpiece, essence of life measures turning to be in dimension, computational actual measurement is worth the difference that is worth with the target, the size of the value that press difference and losing undertake feed or retreat a knife. To numerical control lathe, deserve to have pair of knife functions besides minority besides, basically use pair of Dao Yi, right knife piece or try cut work to the knife. Make to Dao Yi with appropriative be opposite outside machine knife, although precision is taller, but cutting tool must clip of along with knife is opposite together. But knife clip is general heavier, tear open outfit is relatively laborious. Changing only especially when bit, try than using with this law cut even slow to the knife. Use pair of knife piece to the knife, as a result of the influence of a variety of errors, not tall to knife precision. Accordingly, at present lathe of most numerical control still is used try cut work to the knife. The before 3 paces of measure and lathe tradition are identical to the knife, it is a shake one's hand in disapproval only see instead of knife of scale advance and retreat input cutting tool to compensate a value with pushbutton. Try cutting work is charge to the advantage of the knife low, precision is tall; Defect is cost time, and some cutting tool (knife of the groove that be like oil) be opposite very hard with this law knife. Because this fumbles in practice,the fast, high accuracy of a knife of a kind of classics outside applying to, end panel or knife of similar oily groove is opposite knife method. This is one kind need not try cut hand to use pair of knife methods. This law can be in need not be opposite Dao Yi, right below knife piece or the premise to knife standard component, try cut pair of knife time to shorten 60% . This law can maintain try the good point that cuts pair of knives, overcome try the defect that cuts pair of knives. External diameter of 1 principle chuck can serve as transverse (X to) to the knife off-the-peg and fiducial, and the end panel outside fixed position piece is fore-and-aft (Z to) to the knife wonderful and fiducial. The size that essence of chuck external diameter measures income is a fixed cost. The Z of the program often is in again to origin outside fixed position piece on end panel, so two direction absolved foretaste to cut, again essence of life is measured, the convention of the reintroduce after the compensation of knife of final cipher out is worth is right knife formalities. Especially fore-and-aft because do not suffer,try cut an effect that measures an error, have a competition to knife precision so cut a way tall to knife precision; Because do not suffer the effect that installs precision, its are righter than standard component to knife precision knife standard is high. 2 methods divide kinds big as a result of the numerical control device of lathe, so the method wants cent to plant undertake parting narrative. Transverse to the numerical control lathe with absolutely position detector to knife measure: Be worth the X that amends order accordingly to clear to compensation; Essence of life measures the external diameter size near chuck rings aperture, write down next this D1, value (when this pace should change chuck only, make, can be worth) with the D1 that writes down directly later; Turn chuck to rings aperture with the hand to direction of point of a knife; Left hand puts a paper between point of a knife and chuck to be pulled ceaselessly move, the right hand moves an operation with the hand first fast hind stand by point of a knife slow to chuck external diameter, pull till newspaper do not move till, the X on the optical screen when setting this is D2 to indication value; If amount of subsequently treatment penetration of a cutting tool is small, can take no account of quantity letting a knife. optical screen indication value subtracts subtract double newspaper ply is the filling value of the knife again after chuck diameter. The average ply of newspaper is 0.

08mm, local after compressing, be 0.

05mm. So, x Xiang Dao fills be worth =D2-D1-0.

1. computation the value inputs this knife to compensate the X position of date accordingly. If amount of penetration of a cutting tool of the following treatment is large, answer to subtract afore-mentioned values experience lets a knife measure reintroduce. Fore-and-aft to knife measure: Be worth the Z that amends order accordingly to clear to compensation; Turn chuck to fixed position with the hand piece to direction of point of a knife; Left hand puts a paper in point of a knife and fixed position piece between end panel, pull ceaselessly move. The right hand moves an operation with the hand first fast hind locate point of a knife slow an end panel is adjacent, pull till newspaper do not move till, the Z on the optical screen when setting this is Z1 to indication value, criterion =Z1-0 of filling value of Z Xiang Dao.

05. The Z position that inputs computational value this knife to amend order accordingly again can. If machine penetration of a cutting tool later the amount is large, answer to subtract afore-mentioned values experience lets the reintroduce after the knife is measured. Transverse to using the numerical control lathe relative to positional detector to knife measure: Be worth the X that amends order accordingly to clear to compensation; Essence of life measures the external diameter size near chuck rings aperture, write down next this D1, value (when this pace should change chuck only, make, can be worth) with the D1 that writes down directly later; Turn chuck to rings aperture with the hand to direction of point of a knife; Left hand puts a paper between point of a knife and chuck to be pulled ceaselessly move, the right hand moves an operation with the hand first fast hind stand by point of a knife slow to chuck external diameter, pull till newspaper do not move till, the X on the optical screen when setting this is D2 to indication value; If amount of subsequently treatment penetration of a cutting tool is small, can take no account of quantity letting a knife. optical screen indication value subtracts subtract double newspaper ply is the filling value of the knife again after chuck diameter. The average ply of newspaper is 0.

08mm, local after compressing, be 0.

05mm. So, x Xiang Dao fills be worth =D2-D1-0.

1. computation the value inputs this knife to compensate the X position of date accordingly. If amount of penetration of a cutting tool of the following treatment is large, answer to subtract afore-mentioned values experience lets a knife measure reintroduce. "Locking " mechanical part, the X that uses operation general optical screen with the hand shows the value shakes with (D1+0.

10) value is same; Remove afore-mentioned " mechanical locking " , move an operation with the hand, rise tool carrier transverse position of rest; The X that subtracts the X value inside block of the G50 in the program right now optical screen shows is worth, this is cost of cutting tool compensation, the X position that inputs it this knife to amend order accordingly can. If be machined later amount of penetration of a cutting tool is larger, answer to subtract afore-mentioned values experience lets the reintroduce after the knife is measured. Fore-and-aft to knife measure: Be worth the Z that amends order accordingly to clear to compensation; Turn chuck to fixed position with the hand piece to direction of point of a knife; Left hand puts a paper in point of a knife and fixed position piece between end panel, pull ceaselessly move. The right hand moves an operation with the hand first fast hind locate point of a knife slow an end panel is adjacent, pull till newspaper do not move till, the Z on the optical screen when setting this is Z1 to indication value, criterion =Z1-0 of filling value of Z Xiang Dao.

05. The Z position that inputs computational value this knife to amend order accordingly again can. If machine penetration of a cutting tool later the amount is large, answer to subtract afore-mentioned values experience lets the reintroduce after the knife is measured. "Locking " mechanical part, the Z that moves an operation to attend optical screen with the hand shows the value shakes + 0.

05; Remove afore-mentioned " mechanical locking " , move an operation to rise tool carrier fore-and-aft position of rest with the hand; The Z that subtracts the Z value inside block of the G50 in the program show on optical screen right now is worth, it is cost of cutting tool compensation, the Z position that inputs it this knife to amend order accordingly can. If be machined later Z is measured to penetration of a cutting tool bigger, answer to subtract afore-mentioned values experience lets a knife measure reintroduce. 3 notes if program origin is located in be apart from place of Z of end panel of fixed position piece, so aforementioned Z should is worth plus Z to knife filling value, two kinds of types are such. Because blocked ungual reason not to arrive,locate like point of a knife an end panel, z faces a knife to usable chuck end, at this moment knife filling value should undertake conversion. CNC Milling
