Contenium principium parationis CNC machinationis est programmationis CNC, qua normale inter analizationem part is drawingis et determinandum procedentis machinationis est; Calculate vectem instrumenti et accipe datum positionis instrumenti; Scribe programmas CNC machinationis; Crea media controlo; Proofreading program and first piece trial cutting. Duas metodes sunt: manual programming and automatic programming. In breve, it is the entire process of part drawings to obtain CNC Machining programs.

Programmatio manu

definition

Programmatio manu referit ad omnes stages programationis manum impleti. Using general calculation tools and various trigonometric function calculation methods, manually perform tool trajectory calculations and program instructions.

Used for non mold processed parts.

Programmatibus gradibus

CNC process for manual completing part machining

Programmatio manu

Simulatio gressus

advantage

Mainly used for point machining (such as drilling, reaming) or machining parts with simple geometric shapes (such as flat or square grooves), with small computational complexity, limited program segments, and intuitive and easy to implement programming.

shortcoming

For parts with spatial free surfaces and complex cavities, tool trajectory calculation is quite cumbersome, requires a large amount of work, is prone to errors, and is difficult to prove, some of which may even be impossible to complete.

Programmatio automatica

edit

definition

For geometrically complex parts, it is necessary to use a computer to write the part source program in a specified CNC language, and after processing, generate a machine program, which is called automatic programming.

With the development of CNC technology, advanced CNC systems not only provide users with general preparation and auxiliary functions for programming, but also provide a means to expand CNC functions for programming. Programatio parametrorum systemae FANUC6M CNC flexibile est in aplicatione et libere in forma, cum expressiones, operationes logicas, et similes fluctus programmae in linguis computatoribus altissimis nivellis, faciens programmam machinatorium concise et facile intellegere, et facile functionibus, quae difficile sunt facere cum programma ordinaria.

Programatio CNC, sicut programmatio computatoria, etiam sua "a est; Lingua;, But one difference is that computers have now developed to dominate the global market with Microsoft's Windows as the absolute advantage. CNC machine tools are different. They have not yet developed to the level of mutual universality, which means that their hardware differences have made their CNC systems unable to achieve mutual compatibility. Therefore, when I want to process a blank, the first thing I need to do is to consider what model of system we already have for our CNC machine tools.

Determine the coordinate system

(1) Regulations on relative motion of machine tools

On machine tools, we always assume that the workpiece is stationary while the tool is in motion. In hoc modum, programmers can determine the machining process of the machine tool based on the part drawing without considering the specific movement of the workpiece and tool on the machine tool

machining center

Guid93333333;Regulations on the coordinate system of machine tools

The relationship between the X, Y and Z coordinate axes in the standard machine coordinate system is determined by the right-hand Cartesian Cartesian coordinate system.

In instrumento machinae CNC, motus instrumenti machinae a dispositivo CNC controlatur. Pro determinare motum formantur et motum auxiliarum in instrumento machinae CNC, primum est motum et directum motion is in instrumento machinae determinare. Hoc opus est per systemam coordinatae, quod vocatur systema coordinatae machinae.

Exemplo, in maquina militiae, longitudine, transversa, et movementum verticalem lectuli organici. In CNC machining, machine coordinate systems should be used to describe it.

The relationship between the X, Y and Z axes in the standard machine coordinate system is determined by the right-hand Cartesian Cartesian coordinate system:

1) Extende digitum digitum, digitum digitum index, et digitum digitum dextrae manus tuae, faciens illos 90 gradus separatum. Lingua X coordinatum representat, digitus indices coordinatum Y representat, et digitus medius coordinatum Z representat.

2) Anguli puncti in direction positiva coordinatae X, digiti indices puncti in direction positiva coordinatae Y, et digiti intermediae puncti in direction positiva coordinatae Z.

3) Coordinates rotation is in circuitu X, Y et Z representantur a A, B, et C. Secundus regulam spiralae dextrae, direction pollices est direction positiva omnis axis in coordinatibus X, Y et Z, et direction rotationis alterorum quattuor digitorum est direction positiva koordinatis rotationis A, B et C.

[UNK]933434;Regulations on the direction of movement

Directio magnificationis distanciae inter instrumentum et fabricationem est direction positiva cata axis coordinatae. Sequenta figura indicat directiones positivas duorum moventium in lathe CNC.

ObjectClass

[UNK]933232;Z-coordinate

Directio motion is coordinatis Z determinata est a spindulo qui transmitat potestatem sectionis, id est axis coordinatis parallel axis spindalis coordinatus Z, et direction positiva coordinatis Z directo instrumenti relinquens fabricationem Coordinate X

Coordinatus X paralelus aeroplani clampionis opus est, normale intra aeroplanum horizontalum. Defining direction axis X, duos situationes considerabuntur:

1) Si arborem motum rotationis transierit, orientatio instrumenti relinquens arborem est orientatio positiva coordinatis X.

2) Si instrumentum rotatur, duae situationes sunt: quando coordinata Z horizontala est, quando observator videt operam secundum spindam instrumenti, directio +X motion is dextram; When the Z coordinate is perpendicular, when the observer faces the tool spindle and looks towards the column, the+X direction of motion points to the right. Sequente figura X coordinatum lathe CNC monstrat.

Coordinates:

Postquam positivam directionem coordinatum X et Z determinatum est, directio coordinatus Y determinabitur utilis systemam coordinatum Cartesiae dextrae basis super directionem coordinatum X et Z.

Setting of Origin

Origina instrumenti machinae refert ad punctum fixatum in instrumento machinae, quod est origin a systemae coordinatae machinae. It is determined during the assembly and debugging of the machine tool, and is the reference point for the machining motion of the CNC machine tool.

(1) Origin of CNC lathe

On a CNC lathe, the origin of the machine tool is generally taken at the intersection of the chuck end face and the centerline of the spindle. Meanwhile, by setting parameters, the machine tool origin can also be set at the positive limit position of the X and Z coordinates.

Origin of CNC milling machine

Centrum facie inferioris lateris spinae in novissimo loco tres axorum est.

Lathe programming

edit

For CNC lathes, different CNC systems have different programming methods.

Instruction for setting the workpiece coordinate system

Instruktio est, qua originem systemae coordinationis operationis indicat, et cognoscitur quasi punctus nullus programmationis.

Instruction format: G50 X Z

In formula, X et Z sunt dimensiones in directionibus X et Z ab initio punctis instrumenti tip usque ad originem systemae coordinationis operationis.

Quando mandatum G50 executum est, instrumentum machinae non movetur, id est, axes X et Z non moventur. Sistema memoria sunt valorum X et Z internalis, et valorum coordinatorum in cambiamento CRT monstrationis. Hoc est equivalent ad aedificandum systemam operantis coordinatum cum origine operantis sicut originem coordinatorum in system a.

CNC lathe

Methodus programationis systemae grandissimae:

1. Dimensiones absolutas et incrementales

In CNC programming, usus duo modi represent are the coordinates of tool positions: absolute coordinates and incremental (relative) coordinates. When programming CNC lathes, absolute value programming, incremental value programming, or a combination of both can be used.

:: 9332; Programatio valorum absoluti: Valores coordinationum omnium punctium coordinationum a origine systemae coordinationum operantium, vocatis coordinatibus absolutis, a X et Z representatae sunt.

●933333;Incremental value programming: The coordinate values in the coordinate system are calculated relative to the previous position (or starting point) of the tool, and are called incremental (relative) coordinates. Coordinates X a U reprezentantur, coordinates Z a W reprezentantur, positivas et negativas a direction motion determinantur.

2. Diameter programming and radius programming

When programming CNC lathes, a cause of the circular cross-section of the machined rotary parts, there are two ways to represent their radial dimensions: diameter and radius. Metodo usata per parametros systemae determinata est. Quando claudes CNC exit fabricam, generale in programmationem diametricam constituuntur, sic magnitudo in oriente X axis in programma est valor diametrica. Si praecepta est radius, necesse est mutare parametros relevant in system a ut possit illum in stato radius programmationis.

3. Dimensiones metricas et Anglicas

G20 imperial size input G21 metric size input (Frank)

G70 imperial size input G71 metric size input (Siemens)

There are two forms of dimension annotation in engineering drawings: metric and imperial. The CNC system can convert all geometric values into metric or imperial dimensions using codes based on the set state. After the system is turned on, the machine tool is in metric G21 state.

The conversion relationship between metric and imperial units is:

1mm0.0394in

Ngu933434; Maximum speed limit G50

In addition to the coordinate system setting function, G50 has also the function of setting the maximum spindle speed. Exemplo G50 S2000 significat maxima velocitatem spindle ad 2000r/min. Ut constantem velocitatem linearum supervisorem pro secessione, ut non adfligeret accidentes, necesse est limitare velocitatem spindle.

2. Feed function F

Functio F fretum fertilis, quod ex codice F adresse et pluribus numeris subsequentibus compositur.

Guid9332; Feed command G98 per minutum

Post executionem commandi G98 systema CNC determinat quod unitatem fertilitiae per F est mm/min (millimetri/minuta), sicut G98 G01 Z-20.0 F200; Tempus fertilis in segmento programae est 200mm/min.

●933333;Feed command G99 per revolution

Post executionem mandatum G99 systema CNC determinat quod unitatem fertilitiae per F est mm/r (millimetros/revolutionem), sicut G99 G01 Z-20.0 F0.2; The feed rate in the program segment is 0.2mm/r.

Instructionem imputationis

(1） Instruction Fast Positioning G00

Prima optio est operatores CNC. Discipuli qui internacionalis CNC et exercitus CNC praeterierunt poterunt esse, sed competitio pro hoc positio opus maxima est. Hoc maximus in omni collegio vocationis in ingenieria disponibilis est, ut discipulis de scholas vocationis et scholas technicas non mentionant. At present, the CNC operation positions in China's machining industry have basically reached saturation. Alii discipuli mihi dixerunt, quia socii eorum, qui a junior schola graduati sunt et in operationibus CNC quinque aut sex annos antequam eis laboraverunt, iam operarii artificii cum decentibus salariis, ita sentientes valde desperati. Dixi eis quod comparationem oportet non est praesentem sed futurum development.

Secunda, CNC programmer. Many machining enterprises use automatic programming to generate CNC machining programs, so they need to learn CAM software. Different unitates diversas typos software CAM utilizat, sed metodes processionis similes sunt, ita necesse est unum bene discere. However, as a CNC programmer, the requirements are high and the responsibility is also significant, so rich machining experience is required. In hoc case, non est realistis discipulis, qui nunc scholam reliquerunt, statim accipere ad hanc positionem. Per exercitum tempus est ab uno usque duo annos usque ad tres usque ad quinque annos.

Tertio, CNC maintenance personnel aut post venditionem personnel. Haec positio maiores necessitates habet et maxime defecit in agro CNC. Non solum divites scientiae mechanicae requirit, sed etiam divites scientiae electricae. Si hoc direction elegistis, potest difficilem esse (sicut frequenter vias negotiorum), et necesse est semper discere et accumulare experientiam. Hic positio plus curriculum requirit, ita tempus proficientiae longius erit, sed et merces relative generos erit.

Quarto, CNC venditor. Praeda pro hoc positio est generossima, et scientia professionalisma necessaria non est tantum, sed necessaria est excellentia eloquentia et bona scientia societae, quae non sunt aliquid, quod ordinari homines potest facere.

Contenium libri textoris adequatum esse pro necessitatibus programationis praeceptionis cum maxime accepta tecnologia interactiva programmantis graficae quae fundata est in software CAD/CAM quasi contentio principale. Et docentes technicas praecicales, quales operationes software et programmationes, etiam quanta scientiae basic includere debet, ut legitori intellegent naturam et rationes post eam.

Structura libri litterae. Discipulus CNC programationis tecnologiae est procesus progressionis continuatis in stagis, sic contentio librorum textilium rationale dividetur secundum diversos stages discendi. At the same time, systematically summarize and classify the content from an application perspective, making it easier for readers to understand and remember it as a whole.

Contentum et discentem procedentem

Stage 1: Basic knowledge learning, including basic knowledge of CNC machining principles, CNC programs, CNC machining processes, etc.

Phase 2: Discens CNC programming technology, with a preliminary understanding of manual programming, focusing on learning interactive graphicing technology based on CAD/CAM software.

Stage 3: CNC programming and machining exercises, including a certain number of actual product CNC programming and machining exercises.

Methodos et scientias discere

Like learning other sciences and skills, mastering the correct learning methods plays a crucial role in improving the efficiency and quality of learning CNC programming technology. Hic sunt pauci propositiones:

Concentrate pugnare annihilationis, perfecite pondus discendi in breve tempore, et in tempore tempore applicate illum ut non disceret discendi stili marathonis.

:: 9333333;Reasonably categorizing software functions not only improves memory efficiency, but also helps to grasp the overall application of software functions.

Ex principio saepe gravius est ad cultivandum standardisum operationis habitum et robustum et meticulus opus, quam simplicem discendum tecnologiam.

Recorda problemas, errores, et punctus discendi qui occurrant in vita cotidiana, et hoc processus accumulation is est procedus continuo improvinis nivellum eius.

Quomodo CAM discere

Discipere tecnologiae interactive programmationis graficae (etiam clave puncti CAM programmationis) in tres aspectos divisi potest:

1. Quando software CAD/CAM discit, focus super functiones principales magistrare debet, quoniam etiam software CAD/CAM conformit ad so-appellatum principem "20/80", quod significat, quod 80% applicationum solum 20% functionum eius opus est.

2. Conventiones opus standardissimas et standardissimas cultare est. For commonly used machining processes, standardized parameters settings should be carried out and standard parameters templates should be formed. These standard parameters templates should be directly used in CNC programming of various products as much as possible to reduce operational complexity and improve reliability.

3. It is important to accumulate experience in processing technology, familiarize yourself with the characteristics of the CNC machine tools, cutting tools and processing materials used, in order to make the process parameters more reasonable.

Instruere debet quod experientia praecipientia est constituens important is tecnologiae programmationis CNC et solum per maquinas realitas accipere potest, quod ex omni libro doctrinae CNC replicare non potest. Quamquam haec liber coniunctionem praecipientium perfectum emphasis est, dicitur quod mutationes factoribus procedentis generationis in diversis mediis processionis difficiles sunt in scripto forme perfecti expressi.

Finally, like learning other technologies, we must achieve the goal of "disdaining the enemy strategically and valuing the enemy tactically". We must not only establish confidence in achieving our learning goals, but also approach every learning process with a down-to-earth attitude.
