And, NC machining data are read one block at a time, a fixed cycle is selected by a selecting circuit 11 and its coordinate value is stored, and as the fixed cycle is carried out again, a coaxial circle data and a color data are determined by a coaxial cycle determination processing circuit 15 and a color per tool determination processing circuit 17 respectively. Then, a drawing data is formed by a drawing data processing device 9 and the tracks of tools are displayed on a CRT display 6 and an X-Y plotter 7. Accordingly, the types of tools, the order, number of times, method, etc. of machining are displayed by a simple expression, which can be easily judged afterward, obtaining an excellent drawing checking device.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention allows tool trajectories of NC machining data to be displayed on a CRT screen or
- It relates to a plot checking device that automatically plots and checks a plot on a Y plotter, and particularly relates to a plot checking device suitable for examining fixed cycle machining.

[Conventional technology]

Conventionally, as a device of an automatic NC machining program creation system, the tool trajectory of the created NC machining program is displayed on a CRT screen as shown in FIG. ) There is a drawing checking device that automatically draws a drawing on an X-Y plotter and 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 marks such as ○ or Δ9 are attached to each tool code to distinguish them.

, [Problem to be solved by the invention] However, -a hole drilling requires fixed cycle processing at the same hole position using different tools, such as center drilling such as tapping, and pilot hole drilling. There are many things. In such cases, it is difficult to judge because the marks overlap because they are the same machining point, and in machining that uses multiple tools, it is especially difficult to determine later how many times a single hole has been machined. I end up. For this reason, the operator must constantly monitor the data, and the longer and more complex the NC processing data, the more difficult it becomes to understand what the later data is even after checking the drawing. Ta.

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 using hour wheel expressions.
In order to solve the above-mentioned problems, we at Kyoki Invention aimed to provide an excellent drawing check device that is clear, easy to work with, does not require constant monitoring by workers, and can lead to labor savings. The means includes an input means for inputting NC machining data and required data, an NC machining program memory that stores the read NC machining data, and a selection circuit that selects a required machining point from each machining point in the NC machining data. A machining point processing circuit that organizes predetermined machining point data such as coordinate values, tool names, and machining types at selected machining points, a machining point data table memory that stores the organized machining point data, and a machining point data table memory that stores the organized machining point data. A concentric circle determination processing circuit that applies concentric circle setting data to each machining point in the machining point data table memory, and a concentric circle determination processing circuit that applies the concentric circle setting data to each machining point in the machining point data table memory, and a concentric circle determination processing circuit that applies the concentric circle setting data to each machining point in the machining point data table memory. a determination processing circuit, a drawing data processing device that processes and outputs drawing data based on concentric circle data determined by the concentric circle determination processing circuit and color data determined by the tool-side/color determination processing circuit, and each of the above-mentioned circuits. This apparatus is characterized in that it is comprised of a central processing unit that controls the drawings of NC processed data.

[Effect]

The canned cycle is extracted by the selection circuit, and the x and y coordinate values at each canned cycle are memorized. When the canned cycle is performed again with the same x and y coordinate values (the canned cycle is the same as the previous one) But it doesn't matter if it's something else), that x
, Concentric circles are drawn with the y-coordinate position as the center, and the radius value increases one after another for each machining order, and the display is color-coded depending on the tool. This allows you to 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 a mark drawing method for each fixed cycle as in the past.
