[Prior Art] FIG. 14 is a configuration diagram of an entire electric discharge machine including a machining condition generation device, and FIG. 15 is a configuration diagram of a conventional machining condition generation device. In the figure, reference numeral 1 denotes a machining condition generation device in electric discharge machining, 6 denotes an electric discharge machining device, 7 denotes a power supply, and 8 denotes a numerical control device that drives and controls the electric discharge machining device 6 according to the machining conditions set by the machining condition generation device 1.

The condition data unit 3 is an output unit that outputs the generated processing conditions.

Next, the operation will be described. Based on the specifications required for the workpiece, the user can select the machining bottom area a1, machining depth a2,
Required specifications and finished surface roughness from a1 to an, such as electrode reduction amount a3
Required specifications such as c1, electrode consumption c2, and machining time c3 are input from the input unit 2.

There are processing condition generating apparatuses disclosed in JP-A-62-130131, JP-A-64-11715 and JP-A-63-307051.

[Problems to be Solved by the Invention] Generally, in processing, when the finishing accuracy is to be improved, the processing speed is greatly reduced. For example, Fig. 16 shows the surface roughness-machining speed characteristics for each electrode consumption ratio in electrical discharge machining. You can see that. In addition, the surface roughness classification value shown in JISB0601 is 12.5μmRmax, the next coarser classification is usually 25μm
Rmax, see Fig. 16 from 12.5μmRmax to 14μmRm
If the condition is relaxed to ax, the processing speed is increased by a factor of 2 to 2.5.

Therefore, conversely, if the finished surface roughness is improved, the machining time increases rapidly. Therefore, in order to reduce the machining time and manufacturing cost, the finished surface roughness should be as small as possible without impairing the required functions. It is effective to make. Also,
At a surface roughness of 14 μm Rmax, the electrode wear rate is 2% to 3%.
%, The processing speed is improved by 30% or more. Further, at the same processing speed, the surface roughness and the electrode wear rate have an opposite relationship. As described above, generally, the finished surface roughness, electrode wear rate, and processing speed, which determine the accuracy of the workpiece, are dependent on each other, and where to compromise is different for each user or workpiece.

[Embodiment] FIG. 1 is a configuration diagram of generation of machining conditions for electric discharge machining according to an embodiment corresponding to claims (1), (4), and (5).
In the figure, the same reference numerals as those in FIG. 15 indicate the same or corresponding parts. Reference numeral 9 denotes a data conversion unit that converts information input in the importance display into each required specification. Here, as required specifications that are dependent on each other, the finished surface roughness that determines the accuracy of the workpiece, electrode consumption, and processing time are extracted, coordinate axes corresponding to these required items are created, and the plurality of coordinate axes are defined. Combinations are made so as to satisfy the subordination relationship, and a region including the combined coordinate axes is represented by a triangular figure as shown in FIG. In this triangular figure, a-axis is machining time, b-axis is electrode wear,
If the c-axis indicates the importance of the finished surface roughness, therefore, if the importance of some of these required specifications changes, the importance of the other specifications also changes accordingly and can be input collectively. .

Next, a description will be given of a processing condition generating method according to the embodiment. First, it is assumed that the finished surface roughness, electrode wear, and processing time are set and input at the position C (cx, cy) in the triangular figure. This position information is received by the input unit 2 and sent to the data conversion unit 9. The data conversion unit 9 uses this position information as required specifications, that is, finished surface roughness c1, electrode consumption c2, processing time.
Convert to c3. The processing conditions are generated by the processing condition generation unit 4 based on the converted required specifications and the data from the processing condition data unit 5. Therefore, according to this, if the importance of the required specifications of any of the finished surface roughness, electrode wear, and processing time is changed, the importance of the other required specifications also changes correspondingly. The user can easily set the required specifications corresponding to the processing purpose and processing step without considering the influence on other required specifications.

FIG. 3 is a block diagram showing the generation of machining conditions for electric discharge machining according to an embodiment corresponding to claims (2), (4) and (5).
In the figures, the same reference numerals as those in FIGS. 1 and 15 indicate the same or corresponding parts. 10 is a sufficiency generation unit that obtains mutually dependent requirements in the generated processing conditions as a degree of sufficiency related to each other, and 11 is a request that displays the sufficiency of the required specifications obtained by the sufficiency generation unit 10. A specification display unit 12 is a processing condition correction unit that analyzes a change in the degree of satisfaction and corrects the processing condition. Here, the finished surface roughness, electrode wear, and machining time are taken out as required specifications which are dependent on each other, and these sufficiency ratios are represented by a triangular figure as shown in FIG.

Next, a description will be given of a processing condition generating method according to the embodiment. First, based on the specifications required for the workpiece, the required specifications for the processing bottom area a1, processing depth a2, electrode reduction amount a3, etc. a1 to an and finished surface roughness c1, electrode consumption c2, processing time c3 Is input from the input unit 2, the processing conditions are generated by the processing condition generation unit 4 based on the input specifications and the data from the processing condition data unit 5, and sent to the output unit 3 and the sufficiency generation unit 10.

Then, when processing according to the input required specifications is possible, position information of the input required specifications is obtained.On the other hand, when processing according to the input required specifications is not possible, the position information close to the input required value is obtained. The position information of the required specification that satisfies the dependency is obtained. Further, the obtained position information is output to the output unit 3.

In other words, the position information when the processing conditions meet the input required specifications is the center of gravity G (0,0) of the triangular figure.
For example, processing time 10 hours, electrode consumption 2%, finished surface roughness 8
When the actually possible processing conditions were 12 hours, 2%, and 8 μm, respectively, with respect to μm, as shown in FIG.
Time information of the position D that has been lowered is obtained. In addition,

When the user inputs “satisfied” with respect to the required specifications relating to the actual processing conditions displayed on the display unit 11, the processing conditions are set.

On the other hand, assume that the user wants to shorten the processing time. To shorten the processing time, it is necessary to sacrifice electrode consumption or finished surface roughness. First, the display D in the triangular figure is moved to a target position using a keyboard, a mouse (not shown), or the like, and the position information is input to the input unit 2.

This will be specifically described with reference to FIG. For example, there is a processing condition according to the required specification, and the position information of the input required specification is displayed as D at the position of the center of gravity as shown in FIG. However, if the processing time input by the user as a required value can be further shortened and electrode consumption can be sacrificed, the processing time can be further shortened and the surface roughness can be sacrificed at the position shown in FIG. In this case, the display D is moved to the position shown in FIG.

On the other hand, the relationship between the deviation of the display position in the triangular figure from the center of gravity and the correction of the processing condition is programmed in the processing condition correction unit 12 in advance. Table 1 is an example of the program, and includes the relationship between machining time, accuracy, and machining surface roughness, which are machining conditions such as a single discharge peak current, a single discharge time, and an electrode shift amount. The processing condition correction unit 12 calculates the deviation of the display position input from the input unit 2 from the center of gravity, and corrects the processing condition.

FIG. 8 is an input screen illustrating an input state of these input specifications. The data converter 9 receiving the position information C (cx, cy) from the input unit 2 converts the position information into required specifications of a finished surface roughness c1, an electrode wear c2, and a processing time c3.

Then, the processing condition generator 4 that receives the required specifications a1 to an from the input unit 2 and the required specifications c1 to c3 from the data converter 9 is described in advance in the required specifications and processing condition data unit 5.

A coordinate axis corresponding to the machining time c3) is created, the plurality of coordinate axes are combined so as to satisfy the dependency, and the position information of a triangular area whose center of gravity including the combined coordinate axis is G (0,0) ( dx, dy). Then, when processing according to the input required specification is possible, position information of the input required specification is obtained, and when processing according to the input required specification is not possible, the subordination relationship close to the input required value is obtained. Position information of the required specification that satisfies is satisfied. further,
The obtained position information is output to the output unit 3 (S3) and displayed on the display unit 11 together with the processing conditions (S4).

The processing conditions after the correction are output from the output unit 3 (S10), and the desired processing conditions are obtained.

In the above embodiment, the processing conditions are corrected by the processing condition correction unit 12 as shown in FIGS. 3 and 9, but the processing conditions are corrected by the processing condition correction unit 2 as shown in FIG. A required specification correction unit 12 'may be provided to read the correction of the required specification itself, and the corrected required specification may be re-input to the processing condition generation unit 4 to generate the processing condition. For example, when the required specifications such as “processing speed 10 hours”, “electrode consumption 2% or less”, and “finished surface roughness 8 μm” are input, the degree of satisfaction is displayed as shown in FIG. 4 (a). When inputting as shown in FIG. 4 (b) to increase the processing speed, "processing speed 8 hours""electrode consumption 5% or less"
