In practical applications, a DBF graphics file can represent seven kinds of primitive information, namely: vacancy, cylindrical, conical, inner arc, outer arc, inner sphere, outer sphere. The classification of shape information seems to be a bit more, but there are only two types of graphical elements that make up the corresponding graph: straight lines and circular arcs. The straight line can be described by only two points; so-called arc and sphere are actually part of a circle, so that it is critical to determine some information about the arc or the circle corresponding to the sphere, and a circle can be determined by actually having quantized values of the center and diameter of the circle.
Firstly, acquiring information of primitives forming a graph from a DBF file, wherein the DBF file structure is much simpler than that of a DXF file, so that the primitive information is easy to extract, classifying the primitives (divided into a straight line and a circular arc) according to the acquired primitive information, and then entering the next module for processing.
The processing module of the primitive information is very important, and how to take the appropriate number of points to describe the shape of the graph is the main task of the module. After the primitive is analyzed, only two real primitives, namely a straight line and an arc, are summarized, and for the straight line, only two end points are required to be obtained; for circular arcs, polygons are used to approximately represent circular arcs. The obtained point information is stored in a data structure, and then the next module can be entered for processing.
And generating a tool path file module, wherein the key point is the understanding of the machining process. The point information describing the shape of the figure that has been acquired is put into a container. The DBF parameter has a track step length parameter, which actually fits the graph formed by the straight lines connected by the points again, so that the joint of the two straight lines is smoother.
If the DBF file graph currently inputted by the user is the simplest one of a straight line and a circular arc, the processing procedure of the system and method of the present invention is as follows as shown in fig. 3:
analyzing the algorithm design of the whole software, the most critical part is the acquisition of the points on the graph, if the points are less, the graph which is finally fitted is not close to the original graph, and the processing is failed. In the module for processing primitive information, a Container for storing vertex information is defined in the spline curve class, which is assumed to be Container a, and such a Container is maintained by both the straight line class and the arc class.
The point taking of the straight line class is relatively simple, and only two points need to be taken and put into the Container A. The key point of the arc class is how to obtain the points for dividing the arc, and finally, the points are connected to form a part of a polygon, and then the arc is approximately described. The central angle of the circular arc is easy to obtain, and generally, the central angle is divided once by taking one point by using a method for dividing the central angle. There are two methods for dividing the central angle, one is to set the number of division times, but this method is only for the case of a small central angle, and when the size of the central angle is uncertain, the arch height division method is generally adopted. Arch height division method: according to the definition of the arch height of a circle, assuming that the arch height is h and the radius of the circular arc is r, the angle value of each angle dividing the central angle is acos ((r-h) ÷ r). Of course, h is generally taken to be small for accuracy. Finally, the coordinates of the points of the circular arc are divided, since the radius of the circular arc and the change in the angle of the point with respect to the starting point of the circular arc are known, and the coordinates of the points after rotating by this angle can be easily determined, in particular by multiplying the coordinates of the original point by the rotation matrix (determined from the rotation angle).
Since the above vertex fetching is in the primitive information obtaining module and is not specific to the specific graphics file, how the specific graphics file calls the vertex fetching interface is realized next. In the tool path generating module, firstly, in the class for generating the NC code, an object B of a spline curve is defined, and then we aim to put each vertex information of the whole graph into a vertex container B corresponding to B.
Reading file information, extracting the primitive information, defining corresponding different primitive objects according to different primitives, and initializing variables of the primitive objects by using the variables of the file primitive information, wherein the variables are mainly applied to a linear interpolation algorithm for taking points. And simultaneously putting the primitive objects into an object array called PointerersA, for example, calling a corresponding vertex fetching interface by using the object array at an interface for generating an NC code, wherein the functions of the interfaces are mainly to obtain points for describing primitive shape information and simultaneously store the points into Container A, and then putting the point information in the correspondingly generated Container A into a Container B of an NC code generation implementation class.
In the process of generating the NC code finally, the NC code generation implementation class has an interface for generating a tool path file, generates a corresponding NC code file according to the relevant machining process and the point information (i.e., the shape information of the machining graph) in the ContainerB, and loads the NC code file into the system.
By utilizing the system and the method, a user only needs to input a designed DBF graphic file, and the software system can automatically finish graphic analysis and generate a corresponding NC code, so that the user can carry out corresponding processing.
The numerical control system and the control method for realizing automatic optimization of the cutter path based on the DBF graphic file are adopted, and the system comprises a file information reading module, a primitive information analysis module and an NC code generation module. In the method, a file information reading module reads a DBF graphic file; the graphic element information analysis module divides the graphics in the DBF graphic file according to preset graphic elements; and finally, generating an NC code by an NC code generation module according to the divided graph. Therefore, by utilizing the system and the method, the graph information can be extracted from the CAD graph and converted into coordinate point data according to the data format and the application characteristics of the DBF file, the data is converted into NC codes which can be identified by a machine tool by combining numerical control machining process knowledge, a numerical control machining program is generated, and the machining control of a numerical control system is finally realized.
In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
