Description
Technical field
The present invention relates to a kind of methods for processing Cylinder Surface in four-shaft numerically controlled milling machine tool using macroprogram.
Background technique
With the development of Modern Manufacturing Technology, become increasingly complex to adapt to various shape, required precision is higher and higher
Product, technologically advanced multi-axis NC Machine Tools in machinery manufacturing industry using more and more extensive.These advanced numerical control devices
Process requires to be controlled by program, and the establishment of numerical control program is the important component and numerical control of Numeric Control Technology
One of key technology of processing, in numerical control processing, quality and digital control system, numerical control processing technology and the programming people of program composition
The various knowledge and experiences of member are closely bound up.The efficiency and quality of program composition largely determine the processing of product
Precision and production efficiency.Especially the programming of gang tool proposes very high requirement to the program capability of operator.Numerical control
There are two types of programming modes, first is that automated programming, second is that manual programming.Automated programming, which refers to by automatic programming software, completes journey
Sequence establishment, it can solve the processing problems of complex parts, but its nc program generated is influenced by many factors,
By CAD/CAM software, when CAD is modeled, computational accuracy is influenced first, secondly, being generated NC cutter path by CAD/CAM software
When computational accuracy influence, sometimes post-process link can also have an impact to it, open the nc program of an automated programming,
Can find nearly all be in program simple circular arc and straight line instruction combination, it is troublesome although data are very accurate, almost without
Method understands program.Manual programming is the program development job by being accomplished manually part, includes mainly part Interferogram Analysis, at technique
Reason, data calculate, program and inputs the simultaneously processes such as checking routine, for automated programming, the part that can complete
It is by a relatively simple.Variable is used in a program, and program function is reached by the method for carrying out assignment and processing to variable, it is this
There is the program of variable to be referred to as macroprogram.Custom macro program is the combination using variable, works out various arithmetic sum logical operations, turns
It moves and a kind of of the orders such as circulation can be with the program of flexible Application.Macroprogram has a wide range of applications in production practice, especially
It is more commonly used in the programming of curved surface.Program word is considered as constant in general program composition, and a program can only describe one
Geometry, so lacking flexibility and applicability；And it need only be changed using macro programming for same type of programming
Variable value, without reprograming, so that it may obtain different sizes and the similar program of geometry, there is flexible in application, shape
The feature of formula freedom；It is also equipped with expression formula, logical operation and the similar program circuit of computer advanced language, makes processing program
Terse understandable, realization commonly programs the function being difficult to realize.With popularizing for CASE(Computer Aided Software Engineering) programming, its application is opposite
It reduces, but as a practical technical ability, the horizontal height of numerical control processing person can be sufficiently measured to its grasp.
The difference of macroprogram and ordinary procedure is: in macroprogram ontology, variable can be used, variable assignments can be given,
It can be jumped with operation, program between variable；And in ordinary procedure, constant can only be specified, operation is unable between constant, program is only
Can sequentially execute, cannot jump, thus function be it is fixed, cannot change.Macroprogram is relative to CAD/CAM automated programming, no
It needs to buy expensive software and program is short and small.Therefore half function of thing will be played by macroprogram being skilfully used in the processing of similar workpiece
Effect again.But the establishment of macroprogram and the specialized capability of programming personnel have substantial connection.Macroprogram requires programming personnel except the palm
It holds outside the basic programming instruction of macroprogram, also requires programming personnel that can establish the mathematical model of part feed process and establish phase
Mathematical relationship expression formula answered etc..
With popularizing for numerically-controlled machine tool, more and more enterprises carry out the processing of part using numerical control device, for shape
Simple part, calculating is fairly simple, can complete task using common programmed method.But for non-circular curve,
The part of listing curve and curved surface class there is certain difficulty with the establishment that common method carries out program, although using
CAD/CAM software can automatically generate processing program, but program segment is too long, and the low efficiency processed.The axial direction of Cylinder Surface is cut
Face is dome arc, is processed on the cylinder by the curve of discrete point description, Cylinder Surface, profile arc transition and angled transition,
Forming tool processing is generallyd use in production.Cylinder Surface is that machining accuracy, geometric tolerance, surface quality etc. are exigent
Part is related to multiple complex-curved processing, is programmed with automatic programming software, Yao Jingli three-dimensional modeling, tool- path generation,
The processes such as machining simulation, postpositive disposal and program optimization spend the time longer, up to ten thousand sections of the program of generation, check and modification is tired
Difficulty may accent generation program once cutter goes wrong in process.In the multiaxis number with rotary shaft such as four axis and five axis
Cylinder Surface is processed on control lathe, usually need to generate processing program with programming software, but its processing program is often bulky,
The lookup of inconvenient program is modified.And traditional four axis FANUC lathe manual programmings are the modes of main program combination subprogram, are needed
A large amount of subprograms are individually write, call subroutine carries out circulation in main program, and main program and subprogram will form several
Independent program, program management, lookup, modification are inconvenient.
