How to make sure with the treatment that improves numerical control lathe quality is discussed

1CNC Machining analysis for technological efficiency and processing analysis for technological efficiency and craft processing are the pre-construction job that has CNC Machining to workpiece, it must be finished before numerical control to program, after deciding because of technology program, process designing just has a basis. If analysis for technological efficiency is not overall, craft processing is undeserved, create the possibility the mistake of CNC Machining, affect the success of treatment directly, appear even reject. Because the process designing personnel of this CNC Machining wants the technology of a CNC Machining above all,the problem considers to help somebody attain his aim, just have to program. Reasonable the craft processing that undertakes CNC Turning, it is the treatment quality that improves a spare parts and the hinge that produce efficiency. Because this answers to undertake to the spare parts according to part drawing paper craft is analysed, machine content and technical requirement clearly, machine means and treatment course certainly, choose the parameter such as appropriate cutting tool and cutting dosage. Pursue below for example 1 with the graph 2 be two when had we machined cooperate a: ? ? fittings 1 graph 2 fittings: of 2 technologies requirement? ? acute edge pours horny C0.

The logical choice of material of 2 cutting tool and parameter of cutting tool geometry 2.

2.

The material of logical choice cutting tool of material of 1 cutting tool gets on one hand in cutting high pressure, high temperature and violent attrition action, ask good; of tall, wearability and hear resistance wants its hardness again on the other hand get pressure, concussion and vibration, ask its intensity and tenacity are enough. But, the stuff with intensity and good tenacity, its hardness and wearability inevitable poorer, vice versa. Commonly used cutting tool material has high-speed steel, hard alloy, pottery and porcelain material and exceed hard data, before both for commonly used material, and hard alloy material applies in lathe tool the most general. High-speed steel cutting tool does not agree with high speed knife is cut, cutting speed affects calorific amount directly, its heat-resisting temperature makes an appointment with 600 ℃ , and temperature of hard alloy heat-resisting makes an appointment with 1000 ℃ , harder than high-speed steel, wear-resisting, heat-resisting is gotten much. Wait for a characteristic as a result of the high speed of CNC Machining, high power, commonly used CNC Turning cutting tool has lathe tool of sharp contrast lathe tool, circular arc form and figuration lathe tool, to decrease the time that change a knife is mixed convenient to the knife, the standardization of facilitating implementation machining, should use machine clip as far as possible but dislocation lathe tool, material of its razor blade uses hard alloy and coating hard metal more character. 2.

In the actual application that the logical choice of parameter of geometry of 2 cutting tool processes in numerical control lathe, the influence that is apart from the deviation with spare parts high center to wait for parameter of cutting tool geometry as a result of point of a knife of radius of circular arc of lathe tool point of a knife, tool cutting edge angle, lathe tool, sure cause on size error of the radial that be mixed by the axial on size error of treatment spare parts, to cylinder kind the treatment of spare parts surface, as a result of the existence of radius of circular arc of lathe tool point of a knife and lathe tool tool cutting edge angle, make change be producinged by the axial dimension of treatment spare parts, and the metabolic quantity of axial dimension increases along with the accretion of radius of circular arc of point of a knife, follow the accretion of tool cutting edge angle and reduce. Machining sheet paragraph outside when cone spare parts, the metabolic quantity of axial dimension increases along with the accretion of radius of circular arc of point of a knife, along with the change that increases; by the accretion of taper of treatment spare parts to cause dimension of radial of ministry of join of photograph of as small as cone end from this, the metabolic quantity of its radial dimension is reduced along with the accretion of radius of circular arc of lathe tool point of a knife, along with reduce by the accretion of taper of treatment spare parts. If pursue 3 visible. Graph is radius of circular arc of point of a knife of 3 lathe tool columnar to treatment the in affecting style: of kind of spare parts surface? Zuo - the amount of axial size variation that causes by radius of circular arc of point of a knife: Dimension of axial of spare parts of △ A=b-a=r B- , displacement of A- actual axial is measured, radius of circular arc of R- point of a knife. So treatment pursues 1 with the graph when 2 spare partses, according to graph I and graph the appearance of 2 part drawing, the outline outside rough machining can choose radius of circular arc of point of a knife 10.

The D of 8 but razor blade of dislocation lathe tool, the outline outside finish machining can choose R = 0 of radius of circular arc of point of a knife.

The D of 4 but razor blade of dislocation lathe tool, use compensation of radius of circular arc of point of a knife. When the outline outside treatment of lathe of NEIJING-FANUC Oi Mate-TC CAK6136V/750 numerical control, with G42 and in corresponding knife a radius of circular arc of point of a knife losing a person. In order to reduce the machining error that radius of circular arc of point of a knife brings, assure thereby and improve treatment quality. 2.

The in adding up to a quantity to choose numerical control turning to machine cutting dosage of 3 cutting dosage includes to carry penetration of a cutting tool on the back to measure A. , s of main shaft rotate speed or cutting speed V(are used at) of cutting of constant linear velocity, feed speed or feed F. Is the choice principle of cutting dosage: ? ≡ of eggplant of palpitate of violet flesh of  of breed stool money climbs over a wall] Shan of provide for Jiao is sought noisy the predestined relationship reads nest of ≡ of nest of handsome F Wu to wash Jun of  of Shan admire  , determine an appropriate cutting rate finally. Should choose when fine vehicle lesser (but cannot too small) back penetration of a cutting tool measures A. With feed F, at the same time parameter of basis cutting tool raises cutting rate as far as possible, in order to assure treatment quality, improve productivity. 2.

Is the main effect of the fluid of logical choice cutting of 4 cutting fluid: ?  of gourd ladle of Cong spring leg 3 enlighten the cutting fluid that Yao of  of  of sea of  of hazel of live abroad of He of Tao of that Xing of Mei of S of children's hair humorous swings ministry tip to circle ∮ ?0 date or 20 engine oil are cutting fluid; to should have sufficient flow can cool completely when hard alloy cutting tool, when the plasticity material such as turning steel, in order to add cooling fluid had better when the brittleness material such as iron of; Che Zhu, brass, bronze, do not add cutting juice commonly, because collapse is broken cut bits and cutting fluid easy block machine tool pulls lump board when athletic; uses the plasticity metal such as steel of cutting of high-speed steel cutting tool, want to add cutting juice. Machine a graph for example 1 with the graph when 2 spare partses, because pursue 1 with the graph 2 hardwares data is 45# steel, the cutting fluid that chooses so is emulsion. 2.

The method that the jacket of lathe of logical choice numerical control of method of clip of 5 workpiece outfit places workpiece and general lathe are basic and same. If logical choice fixed position is standard with clamp means, the attention reduces the number that hold clip, use built up fixture to wait as far as possible. Except general axis kind the spare parts holds clip directly from centering chuck with 3 claw outside, to a few special spare partses, must logical choice outfit places a method, will bring negative effect to the treatment quality of the spare parts otherwise, cannot produce the advantage that high accuracy of numerical control lathe machines. For example: ? Lei of  of languid of the Lai that endow with ぶ enlighten have a nightmare protects ⑷ of  of ぜ of Quan of  take along sth to sb to bear Ling of Kuo of Cuo of  of Lu of  of law of Qiong  farsighted  to be short of low-lyingpond lie Fei Shan washs  of Quan of  of dredge of ち of Shan Na Fei deceive make ㄗ of any of several hot spice plants of Bei of Xing Huan ァ smooth with a raking suffers from sunken, otherwise easy generation of long and thin axis bends be out of shape, the scientific and reasonable method that hold clip is to convert the right end that stretch activity tip carries an axis on the head, and block ungual place transfer with steel wire clamp. The car causes workpiece to be out of shape with clamping force to prevent diameter when thin wall workpiece, can use annulus of axial clamp, mouth to transfer clamp or the method that use soft ungual clamp, can leave thicker craft flange to use outfit clip beforehand in one aspect of the matter additionally, craft flange is excised again after waiting for sleeve treatment to end. For example, treatment pursues when 1 fittings right end, place workpiece Zun Duan from centering chuck outfit with 3 claw, consider Zun Duan to place shorter, and workpiece diameter is bigger, use so " place " the method holds clip. 3 must undertake machine program weaves correctly, machine quality in order to raise numerical control lathe 3.

The lathe of characteristic numerical control that 1CNC Turning machine program weaves basically is used at the axis kind and dish kind of treatment that waits for swing tower spare parts. No matter why be planted,car place of business is planted numerical control system, they all have common process designing characteristic to be in our country, use at present more is medium the two coordinate of small norms control numerical control lathe continuously. (1) is in a program.

Can use absolutely process designing, opposite process designing or mixture process designing. (Direction of 2)X reference axis uses diametical process designing, namely coordinate of the X in the program expresses with diametical value. (3) is the radial dimension precision that improves work, the pulse equivalent of X direction takes Z to half. (Stock of 4)CNC Turning system the fixed loop of different form dictates, can undertake for many times repetition circular cutting, in order to apply to the good stuff with older mental allowance or forge makings treatment. (The cutting tool point of a knife that 5) uses as a result of real turning is the circular arc with a not big radius, and think when process designing point of a knife is nodded for, because this machines precision to rise, need to use G40, instruction of G41, G42 undertakes cutting tool radius is compensated. 3.

Does the methodological CNC Turning of process designing of 2CNC Turning treatment machine the method of process designing to there is: of two kinds of methods? Stop?3 of otter of silent of far  of appropriate of け silent blanket.

As the development of the computer and process designing software, the application of automatic process designing is wider and wider. The 4 operation skill that must master numerical control lathe, machine quality in order to rise 4.

1 handlers must is familiar with equipment completely and by the operation the manual undertakes because the model of numerical control lathe and system are different,be operatinged, its configure the meeting that attend to have difference, the layout of systematic code and format and operation and Control Panel also each are not identical. The operation face plate that wants lathe of completely familiar numerical control so, Control Panel, by numerical control machine tool " safe operating rules " and " operation manual " undertake ability assures to machine quality machining. 4.

2 master outfit knife and install to knife technology knife and it is numerical control machine tool to the knife it is important that its are reached in treatment a very intractable main job. Outfit knife and to the knife good with difference, reach the staff that affects machine program directly the dimension precision of the spare parts. Master good outfit only knife and assure to machine quality to knife technique talent. General to the knife component is mixed to the knife for handiwork be opposite automatically knife two kinds big. Current, the numerical control machine tool of great majority uses handiwork to the knife, commonly used is to try cut pair of knife ways. It can get more accurate with reliable result. 4.

3 clever the cutting tool when because exist to be machined to the sum of errors when the knife,the cutting tool of the numerical control system that uses numerical control lathe is compensated wears away, can use cutting tool compensation to use so will assure to machine quality. For example, treatment pursues when right end of 2 spare partses, in the corresponding knife that can fill in the knife before treatment filling date place loses a person 0.

8mm, after waiting for treatment, according to measuring dimension readjust the knife fills value. Undertake finish machining can assure the treatment precision of the spare parts again next. 4.

After the system will check program program to be inputted in machine tool face plate, the 4 emulation that use numerical control lathe must be emulated first, let machine program plan to machine indication treatment contrail in CRT upper mould, see a machine tool (cutting tool) the workpiece appearance that motion and imitate treatment give is correct. Pass a program to emulate, can check an order reasonable, because the program is wrong,avoid and cause an accident, reduce the loss of equipment and cutting tool thereby, ensure person is safe, assure to machine quality. Anyhow of 5 last words, want to assure the treatment quality of numerical control lathe, the advantage such as the high accuracy that produces numerical control car adequately, high rate. The machine program authorized strength that must consider sound technology to undertake numerical control lathe correctly and the operation skill that master numerical control lathe, undertake whole process is controlled. Alone this, the advantage such as the high accuracy that just can produce numerical control car adequately, high rate. CNC Milling
