Description
Technical field
The present invention relates to field of data storage, particularly field of data storage in the digital control system specifically is meant in digital control system the preservation to graph data and process data.
Background technology
Manufacturing industry is the basic industry of national economy, and the height of manufacturing level is an important symbol of weighing an industrial development degree of country, and the height of numerically-controlled machine level is concerning the height of national manufacturing industry level.
Be accompanied by develop rapidly, for the development of the related software of numerical control service has also obtained big lifting in digital control system.According to the difference of function, numerical control software mainly divides big class, and a kind of is the graphics software of drawing the processing cutter track, and another kind is the machining software of processing according to cutter track.Actual process is, at first draw the cutter track figure by graphic plotting software, then by the digital control processing software processing, yet, the cutter track figure that graphic plotting software is drawn generally can't directly process with digital control processing software, this intermediate demand is the process of conversion together, therefore efficient is not very high just, so, the storage mode of today's numerical control manufacture field data needs the ability of two aspects, can allow on the one hand the easy identification extraction of numerical control software, directly processes, can allow graphics editing software discern on the other hand, easily editor.And current related data storage format does not possess above-mentioned this ability.
Summary of the invention
Technical matters to be solved by this invention provides a kind of data memory format, and digital control system field graphics software and digital control processing software can both Direct Recognition.
In order to address the above problem, technical scheme of the present invention is such:
A kind of Nce data memory format, it is characterized in that: comprise three groups of vector containers that are used to store all object datas, be respectively the CAD container object that is used for the graphics editing data, be used to store machining software directly processing data and finish the demonstration of figure and the CAM container object of online editing, be used to store the parameter container object of the total attribute information of the object data of CAD container object and CAM container object.
Described three groups of vector containers adopt the form storage of pointer chained list.
The invention has the beneficial effects as follows that the Nce data memory format can be directly used in the parsing processing of numerical control software,, do not need to carry out the secondary conversion by digital control system field graphics software and the identification of digital control processing software.Therefore improve working (machining) efficiency, avoided the error rate of data in transfer process.
Embodiment
In order to make technological means of the present invention, creation characteristic, to reach purpose and effect is easy to understand, below further set forth the present invention.
A kind of Nce data memory format, comprise three groups of vector containers that are used to store all object datas, be respectively the CAD container object that is used for the graphics editing data, be used to store machining software directly processing data and finish the demonstration of figure and the CAM container object of online editing, be used to store the parameter container object of the total attribute information of the object data of CAD container object and CAM container object.Described three groups of vector containers adopt the form storage of pointer chained list.

10, star is by the number and the star type specification at center point coordinate, radius, angle;
11, abnormity, it is former thereby produce the figure that obtains after the deformation because of stretching, rotation etc. mainly to have described conventional figure.Whether fill sign and special-shaped type specification by initial form, node coordinate, the figure of figure;
12, all CAD objects are write down in the combination of object.By a vector pointer linked list array and object combination type specification;
13, take pictures a little, describe by the point coordinate and the vertex type of taking pictures;
14, text, by text box lower left corner coordinate, width, highly, font type, character pitch, character row spacing, line of text be rotated counterclockwise angle, text string and text and describe.
The described object of above CAD object type is all inherited the base class sub-object in CAD, that is to say that the structure of above CAD object should be described by comprising two class formations, and a class is itself structrual description, and another kind of is the structrual description of its base class.Above object type has only illustrated itself structrual description.Therefore if the structure of CAD object is done comprehensive explanation, must comprise top two class formations and describe.
Being described below of CAD object base class structure:
The base class structure by object ID, machine direction, parameter reference, when drawing cutter line, cutter path parameter, layering machined parameters, path layering the character string when the parameter group number of anterior layer, record CAD object and particular value, whether choose sign, viewdata pointer chained list to form.
Drawing the cutter line structure is described below: draw the cutter line by draw cutter point place segment number, draw the cutter point at the ratio of current location, draw cutter line type, draw the cutter line length, draw cutter line subtended angle, seal length (only be used to seal draw cutter line type) and form.Wherein guide line class shape has four types: nothing, wedge angle, tangent line arc, seal.
The cutter path argument structure is described below: the cutter path parameter is by sagitta error, compensation orientation type, interior inclined to one side value, outer value, the inside and outside inclined to one side sign partially of cutter compensation type, tool diameter size, switching type, straight line approximating curve.
