Description of the Invention: [Technical Field] The present invention/step and graphical inspection system and method, in particular, relates to a small line segment pattern inspection system and method. [Prior Art] In the graphics processing, the small line segment is a general concept, and the specific data range has no exact definitions. 'But in general, the length is less than the line segment of 〇1, round, 1/4 arc, etc. The primitives can be called small segments. Figure (&) - (4) is a simple example of a small line segment in a part drawing. Figure 丄 (1) is the original image of the small line segment, Figure 1 (1) is the right end of the small line segment after magnifying ten times, and Figure (c) is the sharp angle of the small line & From Fig. 1, we can find a small line segment whose original visual effect is a straight line. After zooming in, a sharp angle pattern appears at the f-end portion. When the part is subjected to wire cutting, the wire cutter cannot process parts with such sharp corners. ::Cutting machine uses electrode wire to discharge and corrode metal to achieve: Because of its high cutting precision, it is widely used in high precision. Commonly used electrode wires are molybdenum wire, tungsten wire, brass, and the like, in the case of a sharp angle between 0·03 and α1_, the mm level. When the above-mentioned small line segment appears in the processing pattern, the wire may not enter the sharp corner for cutting. If it is expensive, it is not reusable. In the meantime, the waste of the electrode wire will also not only waste the processing material and timely processing of the parts. The cost of "..., 4 can be reduced, so it is necessary to ensure the correctness of the processing path as much as possible, that is, it needs to be detected. Add 201001304 whether there are unprocessable parts in the work pattern to remind the processor to process such graphics. However, the processing of the graphics is generally performed by the naked eye, but the naked eye can not detect all the small line segments smaller than the specified range, so It is not guaranteed whether the processing pattern satisfies the processing conditions, resulting in loss of problems during processing. [Invention] In view of the above, it is necessary to provide a small line inspection system and method capable of accurately detecting whether the part graphic to be processed is Meet the processing standard to improve the quality of the part graphic, and ensure that the wire cutting machine can process the part correctly according to the part graphic. A small line segment graphic inspection system runs in the computer, the computer is connected with a graphic library and a display device, the system Including: parameter setting module for setting parts The allowable value of the length of the small line segment in the graphic; the graphic selection module, configured to read the part graphic from the graphic library, select a graphic inspection area in the part graphic, and determine the need to check in the graphic inspection area The primitive, the graphic element includes a line, a line segment and an arc; the primitive segmentation module is configured to classify the graphic element into a line, a line segment and an arc, and divide the line into a line segment and an arc, and The segmented line segment and the arc are merged into the graphic inspection area; the primitive detection module is configured to calculate the length of each line segment and the circumference of the arc in the graphic inspection area, and determine the length of each line segment and Whether the circumference of the arc is less than the set allowable value; the primitive identification module is configured to identify a small line segment pattern that does not conform to the processing standard by using the prompt mark according to the judgment result, and display the small line segment graphic in the display device 7 201001304 Position in the part drawing. A small line segment graphic inspection method includes the steps of: setting the allowable value of the length of the small line segment in the part graphic; selecting one in the part graphic a graphic inspection area, and determining the primitives to be inspected in the graphic inspection area, the graphic elements including lines, line segments and arcs; classifying the primitives into lines, line segments and arcs; dividing the lines For the line segment and arc, and divide the segmented line segment and arc into the graphic inspection area, count the length of each line segment in the nose pattern; determine whether the length of each line segment is less than the set allowable value; if the length of the line segment If it is less than the allowable value, use the prompt mark to identify the line segment that does not meet the processing standard; calculate the perimeter of each arc in the graphic inspection area; determine whether the circumference of each arc is less than the set allowable value; If the length is less than the set allowable value, the arc indicating the machining standard is marked by the prompt mark; the line segment with the prompt mark and the position of the arc in the part graphic are displayed. [Embodiment] Referring to FIG. 2 It is an implementation environment diagram of a preferred embodiment of the small line segment pattern inspection system of the present invention. The small line segment pattern inspection system 10 is operated in the computer 1 for detecting a small line segment pattern that does not conform to the processing standard from the processing pattern. The small line segment graphic is a general concept, and the specific data range is not specified. However, in general, a line segment, an arc, a quarter arc, and the like having a length of less than 0.1 mm may be referred to as a small line segment. Graphics. The computer 1 is connected to a graphics library 2 and a display device 3. Wherein, the graphic library 2 is used for storing the part graphic of the required detection, and the display device 3 is used for displaying the small line segment pattern with the prompt mark in the part graphic which does not conform to the processing standard, and 8 201001304 shows a small line segment which does not meet the processing standard. The position of the graphic in the part drawing. The small line segment graphics inspection system ίο includes a parameter setting module 101, a graphics selection module 102, a primitive segmentation module 103, a primitive detection module 104, and a primitive identification module 105. The parameter setting module 101 is used to set the allowable value of the length of the small line segment in the part pattern (for example, the length is 0.05 mm), and the allowable value is used as the judgment basis for whether the small line segment pattern conforms to the processing standard. If the length of the small line segment is greater than or equal to 0.05 mm, the small line segment pattern conforms to the processing standard. If the length of the small line segment is less than 0.05 mm, the small line segment pattern does not meet the processing standard. The graphic selection module 102 is configured to read a part graphic from the graphic library 2, select a graphic inspection area in the part graphic, and determine an element to be inspected in the graphic inspection area. The graphic element refers to each graphic element in the part graphic, including lines, line segments and arcs. The primitive segmentation module 103 is configured to classify the primitives into lines, line segments, and arcs, and divide the lines into line segments and arcs at the inflection points of the line segments and the arcs, and divide the segment lines and The arc is merged into the graphic inspection area, and it is judged whether there are repeated line segments and arcs in the graphic inspection area, and the repeated line segments and arcs are removed from the graphic inspection area, and only one repeated line segment and arc are reserved. This ensures that there will be no repeated prompts at the same location in the graphical inspection area. The primitive detection module 104 is configured to calculate the length of each line segment in the pattern inspection area and the circumference of the arc, and sequentially determine whether the length of each line segment and the circumference of the arc are less than the set allowable value. The primitive identification module 105 is configured to use the prompt mark to mark 201001304 according to the judgment result, and display a small line segment that does not conform to the processing standard and display the position of the small line segment pattern with the prompt mark in the part graphic in the display device 3. For example, if the length of the line segment is less than the allowable value and the circumference of the circle is less than the allowable value, the line segment and the arc 'are identified by the red cross line to indicate that the small line pattern does not meet the processing standard. If the length of all line segments is greater than or equal to the allowable value or the circumference of all arcs is greater than or equal to the allowable value', then the small line segment pattern is determined to meet the processing criteria. Referring to Fig. 3, a method for inspecting a small line segment of the present invention is preferably a flow chart of the embodiment. The small line segment graphic is a general concept, and the specific data range is not specified. However, in general, a line segment, an arc, a quarter circle, and the like having a length less than 0.1 mm may be called small. Line segment shape. The parameter setting module 101 sets the allowable value of the length of the small line segment in the part pattern (for example, the length is 0.05 mm). ‘The allowable value is used as the judgment basis of the small line segment map according to the processing standard (step S3〇〇). If the small line segment is greater than or equal to 0.05 mm, the small line segment pattern conforms to the processing standard. If the length of the line segment is less than 0.05 mm, the pattern of the small line segment does not conform to the processing standard. The graphic selection module 102 reads the object to be inspected from the graphic library 2. Shape (step S301). The graphic selection module 102 selects a graphic area in the part graphic, and determines an element to be inspected in the graphic inspection area/check S302). The primitive refers to the & step in the part drawing, including lines, line segments, and arcs. The primitives of the primitive segmentation module are classified into a line, a line segment 201001304 and an arc (step S303). The primitive segmentation module 103 divides the line into line segments and arcs at the inflection point of the line segment and the arc in the line, and merges the segmented line segments and arcs into the pattern inspection region (step S304). The element dividing module 103 determines whether or not there are overlapping line segments and arcs in the pattern inspection area (step S305). In step S305, if the graphics check area memory is in the repeated line segments and arcs, the primitive segmentation module 103 removes the repeated line segments and arcs from the pattern inspection area, leaving only one repeated line segment and The arc (step S306) ensures that repeated gestures are not present at the same location within the graphical inspection area. In step S305, if there are no overlapping segments and arcs in the graphics inspection area, the primitive detection module 104 calculates the length of each line segment in the graphics inspection area (step S307). The primitive detecting module 104 determines whether the length of each line segment is smaller than a set allowable value, for example, a length of 0.05 mm (step S308). In step S308, if the line segment length is less than the allowable value, the primitive identification module 105 identifies the line segment with a color-colored flag (for example, a red cross line) to indicate that the small line segment pattern does not meet the processing standard, and The position of the line segment with the cue mark in the part pattern is displayed in the display device 3. (Step S309). In step S306, the primitive detection module 104 calculates the perimeter of each arc in the graphics inspection area (step S310). The primitive detecting module 104 determines whether the circumference of each arc is smaller than the allowable value of the setting 11 201001304, for example, the circumference is 0.05 mm (step S311). In step S311, if the circumference of the arc is less than the set allowable value, the primitive identification module 105 identifies the arc with a color flag (for example, a red cross line) to prompt the small line segment graphic. The processing standard is not met, and the position of the arc with the cue mark in the part graphic is displayed on the display device 3. (Step S312). In step S308, if the length of the line segment is greater than or equal to the allowable value, or if the circumference of the arc is greater than or equal to the allowable value in step S311, it is determined that the small line segment pattern conforms to the processing standard (step S313). The small line segment graphic inspection system and method is a graphic detection system and method specially designed for two-dimensional graphic design software, which can accurately detect whether the graphic of the part to be processed satisfies the processing standard and is applied to all the graphics of the part to be processed. The small line segment pattern is smaller than the specified range, so as to improve the quality of the part graphic, and ensure that the wire cutting machine can perform the part processing according to the part graphic correctly. The above is only the preferred embodiment of the present invention, and has been used in a wide range of applications. Any other equivalent changes or modifications which are not departing from the spirit of the present invention should be included in the following claims. Inside.
