Description
Technical field
The present invention is to utilize macroprogram in the method for four-shaft numerically controlled milling machine tool processing Cylinder Surface about a kind of.
Background technology
Along with the development of Modern Manufacturing Technology, in order to adapt to variously-shaped becoming increasingly complex, required precision is the highest
Product, the application in machinery manufacturing industry of the multi-axis NC Machine Tools of advanced technology is more and more extensive.These advanced numerical control devices
The course of processing is required for being controlled by program, and the establishment of its numerical control program is the important component part of Numeric Control Technology, is also numerical control
One of key technology of processing, in digital control processing, the quality of programming and digital control system, numerical control processing technology and programming people
The many knowledge and experiences of member are closely bound up.The efficiency of programming and quality determine the processing of product to a great extent
Precision and production efficiency.The particularly programming of gang tool proposes the highest requirement to the program capability of operator.Numerical control
Programming mode has two kinds, and one is automated programming, and two is manual programming.Automated programming refers to rely on automatic programming software to complete journey
Sequence is worked out, and it can solve the processing problems of complex parts, but its nc program produced is affected by many factors,
First affected by CAD/CAM software computational accuracy when CAD models, secondly, generated NC cutter path by CAD/CAM software
Time computational accuracy impact, it also can be had an impact by post processing link sometimes, opens the nc program of an automated programming,
Can discovery procedure be nearly all simple circular arc and the combination of straight line instruction, although data are very accurate, but troublesome, almost without
Method understands program.Manual programming is by the program development job being accomplished manually part, mainly includes at part Interferogram Analysis, technique
Reason, data calculate, program and input and the process such as checking routine, for automated programming, and the part that can complete
By a relatively simple.Use variable in a program, reach program function by the method that variable is carried out assignment and process, this
The program having variable is referred to as macroprogram.Custom macro program is the combination utilizing variable, works out various arithmetic sum logical operations, turns
The a kind of of the order such as shifting and circulation can be with the program of flexible Application.Macroprogram has a wide range of applications in production practices, especially
When the programming of curved surface more commonly used.Being considered as constant at general programming Program word, a program can only describe one
Geometry, so lacking motility and the suitability；And use macro programming, for same type of programming, need only change
Variable value, without reprogramming, it is possible to obtain different size and the similar program of geometry, have application flexibly, shape
Formula feature freely；It is also equipped with the expression formula of computer advanced language, logical operations and similar program circuit, makes processor
Terse understandable, it is achieved commonly to program the function being difficult to.Along with popularizing of CASE(Computer Aided Software Engineering) programming, its application is relative
Reduce, but as a practical technical ability, the grasp to it can fully weigh the level of digital control processing person just.
Macroprogram is with the difference of ordinary procedure: in macroprogram body, can use variable, can give variable assignments,
Can be with computing between variable, program can redirect；And in ordinary procedure, constant can only be specified, between constant can not computing, program is only
Can sequentially perform, it is impossible to redirect, therefore function is fixing, it is impossible to change.Macroprogram is relative to CAD/CAM automated programming, no
Need to buy expensive software and program is short and small.Therefore in the processing of similar workpiece, skilfully use macroprogram will play thing half merit
Effect again.But the establishment of macroprogram has substantial connection with the specialized capability of programming personnel.Macroprogram requires that programming personnel is except the palm
Hold outside the basic programming instruction of macroprogram, also require that programming personnel can set up the mathematical model of part feed process and set up phase
The mathematical relationship expression formula etc. answered.
Along with popularizing of Digit Control Machine Tool, increasing enterprise uses numerical control device to carry out the processing of part, for shape
Simple part, calculates fairly simple, uses common programmed method just can complete task.But for have non-circular curve,
Listing curve and the part of curved surface class, the establishment carrying out program by common method exists for certain difficulty, although use
CAD/CAM software can automatically generate processor, but program segment is long, and the efficiency of processing is low.Axially cutting of Cylinder Surface
Face is dome arc, processes the curve described by discrete point on the cylinder, Cylinder Surface, profile arc transition and angled transition,
The most generally use forming tool processing.Cylinder Surface is that machining accuracy, form and position tolerance, surface quality etc. are exigent
Part, relates to multiple complex-curved processing, with automatic programming software program, three-dimensional modeling to be experienced, tool-path generation,
The processes such as machining simulation, postpositive disposal and program optimization, spend the time longer, and up to ten thousand sections of the program of generation checks and revises tired
Difficulty, in the course of processing, once cutter goes wrong, and accent may generate program.Many number of axle in band rotary shafts such as four axles and five axles
Process Cylinder Surface on control lathe, generally need to generate processor with programming software, but its processor is the most bulky,
The lookup amendment of inconvenient program.And traditional four axle FANUC lathe manual programmings are the modes of mastery routine zygote program, it needs
Individually to write a large amount of subprogram, in mastery routine, call subroutine carries out circulation, and its mastery routine and subprogram can be formed some
Independent program, program manages, search, revise and be inconvenient for.
