Current home a lot of just be engaged in numerical control machine tool operating personnel, one part handlers is, very familiar to machining, but the process designing to numerical control machine tool is more unfamiliar; One part is the student of strong finish school, they are right machining knowledge, the theory of CNC Machining and process designing is more familiar, but lack practical machining experience; Also having a lot of handlers never had contacted machining and process designing, then they should study operation of numerical control machine tool, difficulty is very tremendous. So what does the operation skill of numerical control lathe have? To the personnel of machine tools of these numerical control of begin to learn, mastering particular numerical control machine tool to operate skill is very important. On one hand they can avoid to produce accident of machine tool collision, cause machine tool damage; 2 it is to be able to be in shorter time, the numerical control machine tool that can raise handlers quickly handles mastery of a skill or technique, ;equal;fitter;fittest;qualified;equal to own job. The operates skill academic knowledge that machine tool of a few numerical control introduced below, the hope has a few senses that draw lessons from to the handlers of the numerical control machine tool that just is engaged in. Above all, handlers needs to have a comprehensive knowledge to the numerical control machine tool of the operation. Know the rigid structure of the machine tool: The mechanical construction that should understand a machine tool is comprised; The shafting that should master a machine tool distributings; More want firmly ground to master a machine tool of each numerical control axes losing way; The function that wants each part that masters a machine tool and use, the pneumatic system principle with simple for example and function, principle of simple work of hydraulic pressure system and function; Want to master a machine tool to assist unit working principle and function each additionally, manostat of library of for example knife, cooling unit, voltage, condenser of electric equipment ark waits unit working principle a moment, function and use method, and the working principle of each safe door lock, function mixes the machine tool use method. Firmly ground masters the function of each operation pushbutton of the machine tool: Know how to execute an order; After workpiece of the examination after how suspending a program machines condition, restore to suspend condition succeed add executing an order, how to suspend a program; The order is executed again after how changing a course, such. Understanding your place to operate a machine tool is what kind of operating system; Know method of the control principle of numerical control system and job simply; The system uses language of what kind of job, the machine tool machines use software and the language that its use. If handlers is right,do not understand the terminology of this language, need to groom professionally so, when groom need makes nice note seriously, every vocabulary in machine tool software represents what Chinese meaning, must mechanical memorizing undertakes control, in after just can be so, working use a machine tool correctly. Additional, the statement that when handlers also needs to grooming, calls the police to general operation undertakes study control, knowing its Chinese is to represent what meaning, how to solve a problem, how does disappear debug call the police by accident. Additional to handlers, if energy and ability allow, can undertake study control to this kinds of language, have very great help to raising a machine tool to operate skill later so. Next, the hand that wants adroitness control to control numerical control machine tool is moved or automata, adroitness control controls the shift of the axis of each numerical control of the machine tool. Handlers must reach the state of skill comes from practice, so talent for love or money can be accomplished close put freely; Just can be in encounter collide or below breakdown circumstance, handlers is OK and correct and seasonable processing problem, handlers just can form conditional reflex, decisive take step of apply the brake. Additionally handlers wants to be familiar with very much to the machine program of numerical control machine tool; What kind of working procedure and operation, the machine tool should have what kind of action, want to be familiar with very much. When the machine tool executes an order, you just can be in know whether machine tool movement is right for a short while, whether to need to take step of apply the brake. Additional, handlers of every begin to learn has a few scared mentality more or less in the initial stage of manipulator bed, fear machine tool happening bumps into a knife, happen bump machine. After so only handlers mastered the operation of numerical control machine tool in adroitness, ability overcomes 　 of similar scared psychology 　 the 3rd, want to master program editor adroitly, the parameter compensation of each working procedure and cutting tool or the compensation of the diameter of emery wheel and length. Master the programming language that you want to operate numerical control machine tool through grooming above all, process designing method and each parameter compensate a method. The numerical control machine tool with advanced now great majority deserves to have process designing or emulated PC workstation. So the emulation study that abecedarian can have software editor and machine tool cutting first on workstation. In learning process designing process, do not pay attention to imitate result only, heavier if want to learn the process that imitate machines, the treatment that wants clear work needs to use what kind of cutting tool or emery wheel, axis of machine tool numerical control passed contrail of what kind of motion to complete cutting treatment; The machine tool is being carried out specific when a certain working procedure is machined, the component is mobile inside the machine tool position related each and direction; The athletic way of each axes when the attention is carrying out treatment and cut way, include how feed, how to retreat a knife, the speed speed of each labor situations when noticing to be machined in the machine tool and displacement, the rate that the labour of each labor situations receives and displacement. Undertaking machining through emulating software, notice all in imitate process parameter must be inputted correctly, because imitate finishs sth cursorily with respect to optional input,do not want, such likelihoods appear the result of emulation treatment is incorrect; Perhaps cause the collision accident when be being machined actually later, or the spare parts discards as useless. If emulate software to have the function that defends collision test, so be about to use this function, check the validity of process designing. Additional, handlers needs to notice especially: Emulation treatment is a theoretic result only, collision won't happen in representing a machine tool to machine a process in actual cutting, also do not represent the product that can process a qualification. Emulation simulative purpose is to save process designing time, raise a machine tool effective utilization rate, when reducing treatment workpiece debug time, do not represent effective spare parts treatment. Finishing perfect workpiece to machine is the wisdom with handlers of numerical control machine tool and sweat are inseparable. Point 4, machine the treatment skill in the process actually, serious ready-made works, understand blueprint first, affirm the position that should process 　　 work, acknowledge the precision common difference that should machine work place, edit machine program next. The workpiece of the need in wanting to will be machined and cutting tool or emery wheel gets ready, prepare the testing instrument of the need in machining a process, the auxiliary tool that will machine the need in the process and clamping apparatus on deck. When processing the first work, the machine tool should use status of weak condition job to undertake trying cutting. When machine tool program every call a new cutting tool pair of knives perhaps should undertake first when emery wheel, inspection program movement is right. Nextpage 　　 adopts outfit mix as far as possible when 　 workpiece treatment, the workpiece that finish is machined; If need to undertake 2 outfit of need workpiece are placed metrical other perhaps reason, the unity with the fixed position that must assure the 2nd times to hold clip and clip of first time outfit so and standard treatment. If adopt the automatic tabulator of the machine tool, need to maintain those who survey a system automatic to measure speed consistency so. When to the treatment of workpiece precision undertakes detecting, can finish on the machine tool, can decrease 2 times to install the fixed position error of clip so. Additional, the machine tool is machining the certain place of workpiece, when the precision demand of its dimension public errand is higher, handlers is being machined every time after finishing, need to undertake precision is checked, the position of workpiece the next is machined after the examination is eligible again; If the appearance of on workpiece a certain place is by two or many direction machine complex, so the position that the treatment of every direction can affect this place figure or the public errand of appearance, a lesser to workpiece precision influence direction should be machined first when treatment so, next the direction with higher demand of rework workpiece public errand, machine repeatedly finally, approach the precision of a requirement finally. If the instrument is measured to cannot undertake metrical to workpiece in what the level uses on the machine tool, cannot get off workpiece from the machine tool again at the same time undertake metrical, affect the treatment precision of workpiece otherwise, can use the method such as special calipers, plug guage, gauge to detect so, if software of machine tool itself is contained,measure a function, can use machine tool itself to measure workpiece so. After the treatment that completes whole work, undertake detecting in the round to workpiece again. To measuring the treatment of workpiece group by group. At the outset second program is debugged after finishing, need to optimize machine program so. Optimized basic principle is as follows: Assure to machine the premise of quality, optimize cutting parameter, for example labour enters speed, cutting tool or emery wheel rotate speed, transverse feed, treatment deepness is waited a moment; Optimize treatment measure, optimize treatment fiducial, improve treatment efficiency, use tall life cutting tool or emery wheel, reduce the number that change a knife or emery wheel revises a number; Build the mathematical model of sound machine program, edit effective and responsible procedure, the surplus of reasonable setting thick finish machining and frequency and use shape appropriately cutting tool or emery wheel, to improving efficiency, make sure treatment pledges measure is had relatively the result that showing. To assuring to be machined the treatment quality of workpiece should note the following respects: Add man-hour to want to have heat engine for some time to the machine tool, maintain a machine tool each hot balance during mechanical axis is working, maintain what the machine tool machines a process to be stabilized by treatment workpiece temperature as far as possible, and maintain slideway of main shaft of working head, machine tool, guide screw as far as possible, grating feet, cutting tool collet or the cold hot balance of emery wheel extension bar. If the machine tool uses cooling oil and cooling fluid, should maintain its temperature is constant, the temperature of cooling fluid is one of main factors of the precision that affects workpiece treatment, what the cooling system that adopts a machine tool will assure cooling fluid is constant temperature. General plant needs to close in the evening machine, need reopen machine tool the following day, before the bed works, so every nature's mystery needs to have heat engine. For the machine tool utilization rate that raise, have two kinds of methods to be able to realize machine tool treatment. It is after switching on the mobile phone, be opposite original order is nominal revise, a compensation that is far from workpiece is done in all treatment working procedure, so in machining a process, the result is measured of the machine tool to change correction in the basis when the machine tool is machined, after the machine tool is in heat to balance position, correction need not need to be changed again. Additionally one kind of method is, so the period of time after switch on the mobile phone machines the position with workpiece bigger common difference first, after passing period of time next when after the machine tool achieves hot balance, will machine the demand of certain public errand is higher position on workpiece again; Perhaps undertake rough machining with the machine tool first, after waiting for machine tool job to achieve hot balance, have the precision work of workpiece again. Have to much more fiducial, many handle the work of the dimension with precision higher demand. There should be on treatment workpiece first so fiducial define only or two dimension, but the position with dimension precision higher demand, and right same and fiducial the place that has many measure, answer to machine the position with top precision first, next the position with rework inferior precision. Because the machine tool is machining the workpiece when the place of high accuracy to produce waste product easily, the place of that work the others need not be machined, saved finished cost so. Anyhow, the basic principle of treatment: First rough machining, the redundant material take out of workpiece, next finish machining; Oscillatory happening should avoid in treatment; Avoid the hot denaturation when workpiece is machined. The vibration that cause happens have a lot of reasons, the likelihood is laden too big, the likelihood is the resonance of machine tool and workpiece, the tigidity that perhaps may be a machine tool is insufficient, also may cause after cutting tool or emery wheel passivation. We can reduce vibration through undermentioned method: Reduce transverse feed and treatment deepness, examination workpiece holds clip whether firm, the rotate speed that increases cutting tool perhaps reduces rotate speed to be able to reduce resonance, examine what whether be necessary to change additionally new cutting tool. To the abecedarian that numerical control machine tool operates, often produce collision. Often listen to others to say, do not touch a machine tool, go to school won't machine tool operation, this is a kind of special mistake and harmful understanding. Machine tool collision is very big harm to the precision of the machine tool, different also to influence of different type machine tool. Generally speaking, not strong to tigidity machine tool influence is greater, the machine tool of stronger to tigidity dragon door structure, in equal strike the effect below force lesser. If the machine tool is cantilever type,get a structure, and machine tool main shaft is to hold the machine tool construction on bout runner shaft, once the machine tool produces the word of collision, to the precision of the machine tool the influence is deadly. So to machine tool of high accuracy numerical control, collision wants to put an end to absolutely. As long as handlers is attentive with the defends collision method with master regular, collision is completely OK prevent and avoid. The following result prevents collision to be helped somewhat to abecedarian of numerical control machine tool probably. The mainest reason of collision happening: It is pair of cutting tool or the diameter of emery wheel and length input are wrong; The 2 dimension that are pair of workpiece and the initiative position fixed position that other and relevant geometry measure inputs mistake and workpiece are wrong; The 3 workpiece coordinate that are a machine tool fasten setting mistake, or the machine tool was at 0 o'clock in treatment process by replacement, and generation changes. Machine tool collision happens in the machine tool to move quickly mostly in the process, the harm of the collision that happens at that time is the greatest also, answer to avoid absolutely. The initiative level that so handlers wants to should notice the machine tool is executing an order particularly and machine tool are changing cutting tool or emery wheel when, right now once the program edits an error, the diameter of cutting tool or emery wheel and length input are wrong, so very incidental collision. Phase ends in the program, the order of the movement that retreat a knife of axis of each numerical control is wrong, also may produce collision so. To prevent afore-mentioned collision, when using cutting tool and emery wheel for the first time, want to undertake pair of knives carefully, cannot underestimate this problem. To avoid to collide, when handlers is operating a machine tool, want the function of sufficient facial features, observation machine tool has as good as constant movement, have without scintilla, have without noise and unusual sound of sth astir, have without shake, have without scorching. Discover unusual situation should suspend a program instantly, after waiting for machine tool problem to solve, machine tool ability continues to work. Before be being operated at the same time, handlers should accept the security that the machine tool handles to groom, every kinds of machine tool is due and safe operating rules, operate personnel to answer to groom via systematic operation and safety, hold grooms the machine tool on the ability after acceptable mount guard evidence works. Before the job, should know the place of fire extinguisher, and handlers should master the method of fire extinguisher, the position of the baric switch of the machine tool, the position of the inputs power source switch of the machine tool, the position of hydraulic pressure workstation, the method that shuts because of mastering jury, oily to using refrigeration grinder should be in the placement of fire extinguisher 3 meters of the machine tool in. Anyhow, the operation skill that masters numerical control machine tool is the process of a successive, can not accomplish in one move. It is to build mastering a machine tool over the process designing knowledge of the machining knowledge of main operation, foundation and foundation. Skill of operation of numerical control machine tool also is not invariable. It is need imagination of handlers part play and start work the organic combination of ability, it is the work that has innovation sex. CNC Milling CNC Machining
