Description

  The present invention is a sheet metal CAM (computer-aided production) that uses a punch press or the like to analyze and display a tool-corresponding shape or the like of a group of production data in advance when creating tool arrangement data. The present invention relates to a machined shape display device.

  A tool by a sheet metal working machine such as a punch press analyzes a requested tool from a sheet metal working drawing to be produced, sets up a tool on a tool support such as a turret, and places a tool on a sheet metal working drawing. In a group of production orders and the like, the optimal combination of tools mounted on the turret and the proper tool placement on the sheet metal working drawing influence the productivity, so the identification of the tools is an important step. At present, an operator registers a tool to be placed in a turret, and a tool arrangement that can be processed by the registered turret is performed on a sheet metal working drawing.

In the production of blank processing, not only one part but also a nesting process for efficiently arranging a plurality of parts on a material plate material is performed, so it is necessary to register a tool common to the plurality of parts in the turret. To analyze tools common to multiple parts, the operator looks at multiple drawings, lists the required hole diameters, and looks at the number of tools that can be loaded into the turret and the quality of the tool at a time. Must be selected. For example, if the optimum tool is used and the number of tools that can be mounted at a time is exceeded, an alternative tool is searched for, and the processing quality and productivity of the alternative tool are taken into consideration.
However, many sheet metal working drawings have a complicated shape and a large number of holes, and it is very difficult to find a necessary tool by looking over a plurality of drawings. For this reason, proper tool knitting to the tool support such as the turret cannot be performed, or proper tool placement on the sheet metal working drawing cannot be performed, which hinders improvement in productivity and machining quality. Yes.

An object of the present invention is to provide a processing shape display device for processing a sheet metal, in which a whole image of the processing shape of each part corresponding to a tool can be confirmed in a group of groups to be produced, and a necessary tool can be easily grasped. It is to be.
Another object of the present invention is to facilitate generation of tool arrangement data.
Still another object of the present invention is to enable classification of machining shapes by simple processing.

The sheet metal processing FIG. 2 includes, for example, a collection of line data D1 indicating each side of the outer shape, each side of the opening H, or the whole, and the line data D1 is included in each line data D1 by either outer peripheral processing or inner peripheral processing. Attribute information D2 indicating whether there is any is provided. One line data D1 is shown as one line of data with data numbers (1), (2)... In FIG. One line data D1 includes shape type information such as straight lines, arcs, and circles and dimension information based on coordinates and the like. For example, the coordinates of the start point and end point are shown on a straight line, and the coordinates of the start point and end point and the center angle are shown on an arc. In the case of a circle, the center coordinates and radius or diameter are shown.

The attribute information D2 for discriminating between the outer peripheral machining and the inner peripheral machining is not limited to the information directly indicating the distinction between the outer circumferential machining and the inner circumferential machining. For example, the right side of the line in a predetermined direction (for example, counterclockwise) following the closed figure May be indicated by information on whether or not the left side is processed.
In addition, although FIG. 2 demonstrated the case where the figure which shows one component Wa was demonstrated here, the figure which shows several components Wa may be included.

  The drawing designating means 4 is a means for designating an arbitrary sheet metal working drawing 2 by selective input from among the plurality of sheet metal working drawings 2 stored in the drawing storage means 3. For example, the drawing designating means 4 shows a list display 14 of names of each sheet metal working drawing 2 on the screen 13 of the display device 12, and the desired name display 14 a in the list display 14 is displayed from the input means 4. It is assumed that the sheet metal working drawing 2 corresponding to the selected name display 14a is designated by selection by an operator input. The selection of the name display 14a in the sheet metal working drawing 2 is performed by, for example, checking a check box 15 provided side by side on the name display 14a.

The shape analysis means 5 is means for classifying the local machining shapes G included in the plurality of sheet metal machining drawings 2 designated by the drawing designating means 4 according to the types of tools and machining forms.

The processed shape list display 16 includes information on the shape and dimensions of the opening H to be drilled. In the example of FIG. 1, the shape type, size, and quantity for each type of machining shape G are shown. The type of the machining shape G is indicated by, for example, a circle, a corner, an inner straight line, an outer straight line, or the like.

  What is the local machining shape G is determined according to a predetermined standard (not shown) set in the shape analysis means 5. For example, the local processing shape G includes the shape of a hole to be drilled such as a round hole or a square hole, the line of each side indicating the outer shape of the component, and the shape of the opening H to be processed in the component Wa. For example, the shape of each side line shown. In the case of a circle, it is recognized as one local machining shape G regardless of the size. Further, in the case of a closed figure of a predetermined shape such as a rectangle or a triangle, if it is within a predetermined dimension, it is recognized as one local processing shape G. A predetermined dimension is a dimension according to a tool, and when it is a dimension which can be processed by one punch, it is set as one local processing shape G. In the case of one continuous straight line or curve, one local machining shape G is obtained even if the dimension is long.

The shape analysis means 5 classifies such local machining shapes G according to the types of tools and machining forms. By type of tool, the machining shape G having a size that can be machined with one punch is classified according to the distinction of the circle, corner, etc. of the tool to be drilled and the size.
The types of processing forms are classified for the processing shape G that cannot be processed with one punch. For example, a straight line on each side for processing the outer periphery of the component Wa is processed by continuously performing a plurality of times of drilling, and the outer periphery of the straight line is drilled. In that case, as shown on the screen 13 in FIG. 1, a classification name such as “peripheral straight line” is given and classified according to length and direction. That is, if the length and direction are the same, the classification is the same, and if any of the length and direction is different, the classification is different. When the opening H in the part Wa has a size that cannot be machined by one punch, the machining shape G indicating a straight line on each side is given a classification name such as “inner straight line”, and the length and direction. Classified separately.
