Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a drawing check device that automatically plots and checks tool trajectories of NC machining data on a CRT screen or an X-Y plotter, and particularly relates to a drawing check device that is suitable for examining fixed cycle machining. Regarding equipment. [Prior art] Traditionally, as a device for automatic creation of NC machining programs, tool trajectories of the created NC machining programs are automatically drawn on a CRT screen or an X-Y plotter as shown in Figure 5. There is a drawing check device that checks whether correct processing is possible. In such a drawing checking device, when a fixed cycle or a large number of tools are used, conventionally, different types of marks such as ◯, △, □, etc. are attached to each tool code to distinguish them. [Problems to be Solved by the Invention] However, in general, in hole drilling, fixed cycle processing is often performed at the same hole position using different tools, such as center drilling such as tap processing, and pilot hole drilling. In such cases, it is difficult to judge because the marks overlap because they are at the same processing point.
Furthermore, in machining that uses a large number of tools, it becomes impossible to later determine how many times a single hole has been machined. For this reason, the operator must constantly monitor the data, and as the NC machining data becomes longer and more complex, it becomes difficult to understand what is going on in the later stages of the data even when checking the drawing. . The present invention was developed in view of these problems, and in particular, the type of tool, machining order, number of machining times, and machining method at the same machining point can be easily determined later by simple expressions, and is clear. To provide an excellent drawing check device which has good workability, does not require constant monitoring by a worker, and leads to labor saving. [Means for Solving the Problems] In the present invention, the means taken to solve the above problems are an input means for NC machining data and required data, and an NC for storing the read NC machining data. Machining program memory and NC
A selection circuit that selects a required machining point from each machining point in the machining data, a machining point processing circuit that organizes predetermined machining point data such as coordinate values, tool name, machining type, etc. at the selected machining point, and an organization. a machining point data table memory that stores machining point data, a concentric circle determination processing circuit that applies pre-registered concentric circle setting data to each machining point in the machining point data table memory, and correspondence between tools and colors. is applied to each tool in the machining point data table memory, and the concentric circle data determined by the concentric circle determination processing circuit and the color data determined by the tool-specific color determination processing circuit. A drawing checking device for NC processing data is characterized in that it comprises a drawing data processing device that processes and outputs drawing data based on the drawing data, and a central processing unit that controls each of the circuits described above. [Operation] The fixed cycles are extracted by the selection circuit, and the x and y coordinate values of each fixed cycle are stored.
If a canned cycle is performed again with the same x, y coordinate values (the canned cycle can be the same as the previous one or a different one), the radius will be changed one after another for each machining order, centering on that x, y coordinate position. NC with many complex drilling operations by drawing concentric circles with increasing values and color-coded display depending on the tool
Even in the machining data, you can see at a glance which tool was used to make the hole. Note that the initial value and increment value of the radius of this concentric circle can be freely specified, and of course it is also possible to switch to the conventional mark drawing method for each fixed cycle. [Examples] Hereinafter, the present invention will be described in detail with reference to examples and drawings.
