【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a production apparatus according to an embodiment of the invention of claim 1, 101 is processing information provided from processing information input means (not shown), 102 is processing control means, 103 is processing means, 104 is command data,
Reference numeral 105 is measurement data. These are the same as the conventional example. 111 is a communication means, 112 is a database,
Reference numeral 113 is a conversion means. There are a plurality of processing means 103, including those shown in the figure, and the processing control means 102 is provided for each processing means 103.

The processing information 101 in this case is prepared for a specific processing means 103 (in some cases, it may be in the illustrated processing means and in other cases, it may be for the processing means other than the illustrated processing). It also has information indicating the attribute of the information 101 (hereinafter referred to as “attribute information”). The attribute information includes, for example, a machining shape, a machine name, a tool name, and a function for each machining block. Processing control means 102
When the given processing information 101 is applicable to the processing means 103, the processing means 101 gives command data 104 to the processing means 103 based on the processing information 101 and the measurement data 105. The processing means 103 uses the command data 1
Processing is performed in accordance with 04, and the measurement data 105 is fed back to the processing control means 102.

The conversion means 113 refers to the processing information 101 and the database 112 through the communication means 111 in response to a request from the processing control means 102, and if necessary, the processing information 101 can be applied to the processing means 103. The data is automatically converted and sent back to the processing control means 102. Although the database 112 is placed outside the processing control unit 102 in the illustrated example, the database 112 may be placed inside the processing control unit 102.

Next, the operation will be described. FIG. 2 is a flowchart showing the flow of processing performed in the conversion means 113. When this process starts, first, step ST
In step 1, information indicating the attribute of the processing information 101 is read from the processing information 101 of the conversion source (= before conversion). The attribute information may include information other than the above. Of course, if information other than the above is included, more accurate processing information can be transmitted, and if the amount of information is smaller than the above, erroneous conversion may occur, but the processing information can be transmitted easily.
Here, a case will be described in which the above-described information (processing shape, processing machine name, tool name, function for each processing block) is included.

In step ST2, it is checked whether or not the processing machine name in the attribute information read in step ST1 matches at the conversion source and the conversion destination. The fact that the conversion source and the conversion destination are the same means that the processing information 101 of the conversion source
Since it is intended for the processing means 103 of the conversion destination, in this case, obviously no conversion is necessary, and the process jumps to step ST7 and the processing is directly performed based on the processing information 101 of the conversion source. To do. When the processing machine name of the conversion source and the processing machine name of the conversion destination do not match, the process proceeds to step ST3 to convert the processing information 101.

In step ST3, it is checked whether or not the processing shape in the attribute information read in step ST1 can be processed by the conversion destination processing machine. If processing is possible, the process proceeds to step ST4, and if processing is not possible, an error is generated. In step ST4, the processing information 101 of the conversion source is interpreted according to the format of the conversion source information, and processing specifications such as dimensions and processing conditions are read. Next, in step ST5, the processing specifications read in step ST4 are developed and converted according to the format of the processing information of the conversion destination, and the processing information of the conversion destination is created. Then, the process proceeds to step ST6 to check whether the converted machining specifications satisfy the machining specifications of the conversion destination machine and tool. If not satisfied, an error is generated. If it is satisfied, the process proceeds to step ST7, and the command data 114 is given to the processing means 103 based on the converted processing information to perform the processing.

The processing information is converted according to the above procedure. At that time, the database 112 below is referred to. (1) Conversion destination database of processing machine (processing machine specifications,
(2) Data for each machining shape of the conversion source processing machine (including data related to the machining operation and its format) (3) For each machining shape of the conversion destination processing machine Database (including data relating to processing operation and its format) (4) Database showing conversion rules These will be described in detail in the following description of specific examples.

A specific example of the conversion of the processing program of the cutting machine will be described below with reference to FIG.
It will be described in detail along with the flowchart of FIG.

As a first specific example, an example in which a machining program for a machining center is changed to a program for a lathe when machining an outer circumference of a cylinder and machining is performed will be described with reference to FIGS. 3 to 11. .

FIG. 3 is a tool locus diagram when an end mill is used on a machining center. In the figure, 121 is a work, 122 is a work origin, 123 is an end mill, 1
24 is an approach point, 125 is a tool path, and 126 is a final machining shape. The cylindrical work 121 is attached so that its upper surface is parallel to the XY plane, and the center of the upper surface of the work 121 is set as the work origin 122. End mill 12
In No. 3, the workpiece 121 is first processed into the final machining shape 126 by approaching the approach point 124 by fast-forwarding and then performing cutting-feeding through the tool path 125 as shown in the figure. That is, the outer peripheral surface of the cylinder is processed.

FIG. 4 shows an outline of a machining program for performing the machining shown in FIG. Attribute information is described in (). The first line of the program describes the machining shape, the second line the type of the processing machine, the third line the type of the tool, and the subsequent functions each block. The order of these may be changed. At the beginning of the program conversion process, the attribute information is read according to the flowchart of FIG. Since the processing machine name of the conversion source is the machining center and the processing machine name of the conversion destination is the lathe, the two do not match and the step S
Move to T3.

At step ST3, the conversion destination processing machine (=
On a lathe, check whether the required machining shape (= cylindrical outer circumference) can be machined and whether a tool for that purpose is provided. Therefore, the function database of the conversion destination processing machine is referred to. FIG. 5 shows the contents of the lathe function definition database. In this function definition database, the specifications of the processing machine and the shape that can be processed are defined. That is, specifications such as stroke and spindle speed, machining possibility for each machining shape, and tool to be used when machining is possible are also defined. In the case of the outer circumference of the cylinder, it is found that the cutting can be performed using a cutting tool, so the process proceeds to step ST4. Incidentally, FIG. 6 shows the contents of the function definition database of the machining center. It is clear from this figure that it is possible to machine the outer circumference of the cylinder using an end mill.

In step ST4, the processing information is analyzed according to the format of the processing information of the conversion source, and the processing specifications are read. Therefore, the database regarding the processing of the processing shape of the conversion source processing machine is referred to. FIG. 7 shows the contents of the database describing the cylindrical outer peripheral cutting function in the machining center. In the operation name column, there are 4 series of approaches, entries, peripheral cutting, and exit that make up the cylindrical peripheral cutting.
Two operation names are written. The program format of each operation is listed in the format column. This format is not limited to one, and multiple formats are often allowed. Since this format is given and the attribute of each block is marked on the conversion program, it is possible to easily analyze the conversion source program and read the machining specifications. The interpretation method is shown in the processing specification column. When the program shown in FIG. 4 is interpreted according to the format shown in FIG. 7, it can be seen that, for example, the approach point is X = −150, Z = 10 in absolute coordinates, and the radius of the circle is 100. In addition,
Codes not specified in the format column follow the default conversion rules. FIG. 8 is a database showing conversion rules. In the figure, for example, it is specified that the feed rate uses the recommended tool conditions, and the spindle speed is changed so that the cutting speed becomes equal.

In step ST5, the processing specifications are developed according to the format of the processing information of the conversion destination, and the processing information of the conversion destination is created. Therefore, the database regarding the processing shape of the conversion destination processing machine is referred to. FIG. 9 shows the contents of the database describing the cylindrical outer peripheral cutting function in the lathe.
Similar to FIG. 7, a series of operation names constituting the cylindrical outer peripheral shaving, operation formats, and correspondences with machining specifications are described. Since the dimensions, the position, the processing conditions, etc. are known by the above-mentioned procedure, they can be easily programmed in the order of the operations. FIG. 10 shows the contents of the modified machining program.

In step ST6, it is checked whether or not the machining specifications converted in step ST5 satisfy the machining specifications of the conversion destination machine and tool. In this case, since the condition is satisfied, the process proceeds to step ST7. In step ST7,
Machining is performed according to the machining program converted in step ST5 shown in FIG. FIG. 11 is a tool trajectory diagram when machining is performed by the machining program of FIG. In the figure, 127 is a byte, and the other components are the same as those in FIG. The bite 127 first approaches the approach point 124 by rapid traverse, and then the tool path 12 as shown in the figure.
The workpiece is machined to the final machining shape 126 by performing the cutting feed in 5. As a result, it can be seen that equivalent processing can be realized with a lathe.

Next, a second specific example will be described with reference to FIGS.
Will be explained. The second specific example is an example in which a machining program for a machining center is changed to a program for a robot-type machine when machining a through hole. Figure 12 is a tool path diagram on the machining center,
FIG. 18 is a tool locus diagram on the robot processing machine. In these figures, 130 is a drill, 131 is a work, 1
32 is the work origin, 134 is the first arm, 135 is the second
It is an arm. As shown in FIG. 12, in this processing,
After approaching to the point of (X, Y) = (55,50) by fast-forward, move forward in the Z direction, perform drilling, and then move backward by fast-forward.

First, in step ST1, the attribute information is read from the conversion source machining program shown in FIG. It can be seen that the processing machine is a machining center. Next, in step ST2, a match / mismatch between the conversion destination and the conversion source processing machine is checked. Since this case is different, step ST3
Move on to. In step ST3, referring to the database of the conversion destination processing machine shown in FIG. 14, the possibility of processing the processing shape (through hole) in the conversion destination processing machine (robot type drill processing machine) is checked. In the case of this specific example, it is understood that the through hole can be processed using a drill.

In step ST4, the processing shape (through hole) of the conversion source processing machine (machining center) shown in FIG.
The database of the conversion source is referred to, the conversion source program shown in FIG. 13 is interpreted according to the conversion source program format, and the processing specifications are obtained. In step ST5, the database regarding the processing shape (through hole) of the conversion destination processing machine (robot type drill processing machine) shown in FIG. 16 is referred to, and the processing specifications obtained in step ST4 are expanded according to the conversion destination program format. By doing so, the conversion destination machining program shown in FIG. 17 is created. At this time, according to the conversion rule shown in FIG. 8, the orthogonal coordinates (X, Y) are converted into the joint coordinates (P, Q) based on the formula. At this time, the arm lengths L and M of the robot type drilling machine are referred to from the database shown in FIG.

In step ST6, it is checked whether or not the machining specifications converted in step ST5 satisfy the machining specifications of the conversion destination machine and tool. In this specific example, since the condition is satisfied, the process proceeds to step ST7. In step ST7,
Processing is performed according to the processing program converted in step ST5 shown in FIG. FIG. 18 is a tool trajectory diagram showing machining by the machining program of FIG. As a result, it can be seen that the robot-type drill processing machine can realize the same processing.

Next, a third specific example will be described with reference to FIGS.
Will be described with reference to. The third specific example is, when performing blind hole machining, from a machining program for a multi-axis drilling machine,
This is an example of changing to a program for a single-axis drilling machine and machining.

FIG. 19 is a tool locus diagram on a multi-axis drilling machine. In the figure, 140 is a four-axis drill, 141 is a work, and 142 is the work origin. Multi-axis drilling machine (X,
Y) = (0,0) After approaching fast forward,
Drilling is performed by advancing in the Z direction by a depth of 10 and then retreating by fast-forwarding. At this time, since the 4-axis drill 140 is mounted on the multi-axis drilling machine, the work 141
Holes are drilled in the top four places.

First, in step ST1, the attribute information is read from the conversion source machining program shown in FIG. It can be seen that the processing machine is a multi-axis drilling machine. Next, step ST
In step 2, the match / mismatch between the conversion destination and the conversion source processing machine is checked. Since this case is different, the process proceeds to step ST3. In step ST3, referring to the database of the processing machine of the conversion destination shown in FIG. 21, the possibility of processing the processing shape (blind hole) in the processing machine of the conversion destination (machining center) is checked. In the case of this example, it is understood that the blind hole can be processed using a drill.

In step ST4, the database of the processing source (multi-axis drilling machine) of the conversion source shown in FIG. 23 is referred to, and the conversion source program is interpreted according to the conversion source program format of FIG. Then, ask for processing specifications. In step ST5, the database regarding the machining shape (blind hole) of the conversion machine (machining center) shown in FIG. 22 is referred to, and the machining specifications obtained in step ST4 are expanded in accordance with the conversion destination program format. A conversion destination machining program as shown in FIG. 24 is created. At this time, according to the conversion rule shown in FIG. 8, each tool position of the multi-axis tool is set as an approach position and repeatedly developed for each tool position. That is, the tool position is (X, Y) = {(-25, -25),
(25, -25), (25,25), (-25,2)
5)}, which is repeatedly developed for each tool position. At this time, the overlapping S / T / M / F code is omitted. Here, S code means a spindle function, T code means a tool function, M code means an auxiliary function, and F code means a feed function. For example, the following symbols mean the contents in parentheses. S3000; (Spindle speed 3000 revolutions / minute) T23; (Replace with tool No. 23) M05; (Auxiliary function No. 5 = Spindle stop)

The tool position is obtained by referring to the tool database shown in FIG. In this tool database, the shape, size, recommended processing conditions, material, etc. of the tool are described.

In step ST6, it is checked whether or not the machining specifications converted in step ST5 satisfy the machining specifications of the conversion destination machine and tool. In this specific example, since the condition is satisfied, the process proceeds to step ST7. In step ST7,
Machining is performed according to the machining program of FIG. 24 converted in step ST5. FIG. 26 is a tool trajectory diagram showing machining by the machining program of FIG. In FIG. 26, 14
3 is a uniaxial drill. It can be seen that this makes it possible to achieve equivalent machining in a machining center.

Although the attribute information is written in the machining program in the above description, the attribute information may be separated from the machining program and configured as a separate program.

According to the production apparatus of the first embodiment, when processing the same shape, it is only necessary to create one piece of processing information for one processing means 103, and processing information for any other processing means. Can be obtained by converting the one processing information. Therefore, it is not necessary to recreate the processing information for each processing means, and the processing information creation efficiency is improved.

Reference numeral 151 is standard processing information. The other components are the same as those of the first embodiment shown in FIG. The standard processing information is standard information that does not depend on the types of the plurality of processing means 103, and is not prepared for a specific processing means 103.

Next, the operation will be described. First, standard processing information 151 that describes only information that does not depend on the type of processing means 103 is created. FIG. 28 shows an example of standard processing information. As shown in this figure, at least shape information is described in the standard processing information 151. The conversion unit 113 refers to the database 112 and converts the standard information 151 into information in a form applicable to the processing unit 103. Then, based on the converted processing information and measurement data 105, the processing control means 102 controls the processing means 103,
Perform processing.

Although only the shape information is described in FIG. 28, accuracy information about required accuracy such as surface roughness and tolerance may be included. In that case, it becomes possible to automatically select the processing conditions that satisfy the required accuracy.

According to the production apparatus of the second embodiment, when machining the same shape, if only one standard machining information in a simple format is created, it is converted into machining information for any machining means. can do. Therefore, it is not necessary to recreate the processing information for each processing means, and the processing information creation efficiency is improved.

Connect at 11. The numerical controller 202 reads the machining program 201 and checks the attribute information. If the processing machine name in the attribute information and the processing machine 203 shown in the drawing match, there is no need to convert, so the processing program 201 shown in the drawing
According to the above, the processing machine 203 is controlled to perform processing. on the other hand,
If the processing machine name in the attribute information does not match the illustrated processing machine 203, the conversion device 213 determines that the numerical control device 202
In response to a request from the processing program 210, the processing program 210 and the database 212 are referenced through the communication unit 211, the processing program 201 is automatically converted into a processing program for the processing machine 203, and the processing program is sent back to the processing control unit 202. Then, the numerical controller 202 controls the processing machine 203 according to the converted processing program to perform processing. In addition,
In FIG. 29, the database 212 is placed outside the numerical control device 202, but it may of course be provided inside the numerical control device 202. In addition, the machining program 20
1 may be described in a format for a specific processing machine,
It may be described in a standard format that does not depend on the type of processing machine.

Example 4. FIG. 30 is a block diagram showing an embodiment of the invention of claim 3. In the figure, 222 is a factory network, 202-1, 202-2, 202-3,
Reference numeral 202-4 is a CNC device (computer numerical control device) as a machining control means for controlling a machine tool which is a machining means. Each CNC networked in this way
The device has the following protocol (information format) as shown in FIG. (1) A protocol that specifies a specific CNC device and inquires about the data held by the CNC device. (2) A protocol that responds to the inquirer with the data held by itself in response to the inquiry in (1). (3) A protocol that specifies an unspecified CNC device and inquires about the data held by the CNC device. (4) In response to the inquiry in (3), a protocol for returning the data held by the user to the inquirer. Then, it is possible to communicate between the CNC devices by these protocols, obtain necessary processing conditions, and start the processing based on the acquired processing conditions.
Each protocol expresses in 2 bytes the identifier of the sender of the message and the receiver of the message that should receive the message, followed by a sequence of multiple bytes that is the body of the message, and the last 1 byte is an EOM character. is there. At this time, the originator / receiver identifier is 2 bytes, but a larger number of bytes may be allocated in an environment where many CNC devices are connected or when connecting to a wide area network. If the receiver is all devices, 2 bytes of the identifier are set to FFFF.

FIG. 32A is a flow chart showing the flow of processing of the CNC device. In this figure, when it is found that the machining conditions indicated in the NC program do not exist in the machining condition database of its own when the machining is started, an inquiry is made to all the CNC devices about their existence (step ST1). As a result, the existing CNC device replies. Based on the result of this reply, each CNC device is inquired as to whether or not it has the processing condition to be investigated (step ST2). The data included in the content of the inquiry is at least one of optimum machining conditions (feed, cutting speed, cutting) for each specific work material of a specific tool, or parameters of a machining characteristic mathematical model. Then, the reply to it is stored in the own database (step ST3).

In FIG. 32 (b), no machining work is performed,
It is a flow chart which shows the contents of processing performed at night, for example. In this process, each CNC device requests all connected CNC devices to transfer all the processing conditions, and operates so as to take in an object that is not in the CNC device. Unify.

C corresponding to different kinds of processing means
In the case of exchanging data between NC devices, that is, in the case where the data extracted from another cannot be applied as it is, the data is converted using the conversion means as necessary as in the first embodiment. After converting to an applicable form,
Store it in your own database.

By the way, in the networking of the CNC devices, when one CNC device having a large amount of storage devices is placed and a plurality of CNC devices having no storage device are connected, the above (1), ( It is effective to communicate with the protocol of 2). Further, in the case of connecting a plurality of CNC devices having storage devices of the same capacity, it is effective to communicate using the protocols (3) and (4). Furthermore, when there is a system for automatically determining the processing conditions in the network, it is effective to obtain the processing conditions by communicating with the protocols (1) and (2).

As a form of networking, a plurality of CNC devices may be connected to one bus as shown in FIG. 30, but in that case, messages from each CNC device may collide, It is necessary to provide a means for detecting this, but if the path of the ring-shaped network 222 as shown in FIG. 33 is assembled, the need for collision detection is eliminated. In this case, a message irrelevant to oneself may be transferred to the next CNC device, and a relevant one may give a predetermined reaction, and if it is a message sent by oneself, it may be stopped there.

Example 5. 34 is a block diagram showing an embodiment of the invention of claim 4. In FIG. In the figure, 301 is a tool main body and 302 is a tool holder. The tool body 301 and the tool holder 302 constitute a tool 300. Thirty
Reference numerals 3 and 304 designate a data exchange coupling unit for exchanging data by contact or non-contact, 305 a CNC device, and 306 a CPU as an active element embedded in the tool body 301.
(Central processing unit), 307 is a memory similarly embedded in the tool body 301. The memory 307 is the CPU 306
The signal line of the CPU 306 is connected to the data exchange coupling unit 303. The CPU 306 then sends the CNC device 30 via the data exchange coupling units 303 and 304.
It is designed to exchange information with 5. Although not shown in the figure, the CPU 306 which is an active element in the tool 300
The power necessary for the operation of the
It goes without saying that the operation is performed via 3, 304.

The memory 307 stores a machining path suitable for the tool 300 and a tool path relating to the shape to be machined, and the tool 30 is processed during or before machining.
When 0 is attached to the spindle or chuck, the CPU 306 passes through the data exchange coupling units 303 and 304.
And the CNC device 305 communicate with each other. Then, based on the communication result, the CNC device 305 determines the operation of each axis of the machine tool. The storage operation of the machining tool path in the memory 307 can be performed via the data exchange coupling units 303 and 304 in a programming station or the like provided outside the machining machine.

When the CPU 306 is built in the tool 300 as described above, the program of the CPU 306 is also stored in the tool 300.
Will be built into. Therefore, unlike the case where the program is outside the tool, it is not necessary to check the match between the tool and the program each time the tool 300 is mounted. Further, since the CPU 306 is incorporated, the processing conditions can be set automatically and surely. Further, it becomes possible to use information that could not be detected in the past as a control signal, and it becomes possible to perform high-level processing.

Example 6. FIG. 35 is a block diagram showing an embodiment of the invention of claim 5. In the fifth embodiment, the tool 300 in the fifth embodiment of FIG. 34 is added to the A / D converter 308,
A sensor 309 that detects a change in the state of the processing portion of the tool 300.
Is newly added. The detection signal of the sensor 309 is taken into the CPU 306 via the A / D converter 308, and is sent to the CNC device 305 as it is. Further, the detection data is stored in the memory 307 as needed.
A heat sensor, a vibration sensor, or the like can be used as the sensor 309. In this example, more heat is generated during processing,
When the machining portion of the tool body 301 reaches an abnormal temperature, it is detected that so-called chatter occurs due to the temperature rise or direct vibration increase, and the detected information is the CNC. It is designed to be sent to the device. Then, the CNC device resets the processing condition to a safer side based on the detection information, and prevents breakage of the tool and shortening of the life. According to this apparatus, information that could not be detected conventionally can be used as a control signal, in-process machining control can be realized, and advanced machining can be performed.

Further, when the sensor 309 is built in the tool body 301 and the sensor 309 is connected to the CPU 306, it becomes difficult to pick up noise. That is, there is a difference in the length of the signal line of the sensor 301, and the possibility of picking up noise is greatly reduced. Further, since the CPU 306 in the tool body 301 is involved in the data transfer, the transfer data amount can be reduced and the influence of noise can be easily avoided.

Example 7. FIG. 36 is a block diagram of a production apparatus according to an embodiment of the invention of claim 6. In this production apparatus, a plurality of CPUs 306 are embedded inside a long rod-shaped tool body 301 at regular intervals in the length direction. In this case, the CPUs 306 adjacent to each other are connected by a communication line, and each CPU 306 has a CP on the cutting edge side with respect to itself.
It receives a message from U306, and after a certain period of time, sends the message to the CPU 306 on the blade side of itself. This message is given here as an integer value. Then, 1 is added to the value coming from the cutting edge side and the result is passed to the cutting edge side. If the message from the CPU on the cutting edge side does not arrive for a certain period of time from itself, a value of 0 is sent to the cutting edge side. By doing so, the CPU 306 at the blade edge can determine where the tip is not moving by looking at the integer value that is the message, and thereby determining from which part of the tool body 301 the tip is broken. it can. In addition, multiple CPUs
Even if 306 is embedded, if the configuration is such that messages are sequentially transmitted from the blade tip side to the blade base side as in this embodiment, C
The number of wires from the PU 306 is minimized, and the number of wires at the blade base portion does not increase.

As a method of embedding a large number of CPUs 306, for example, as shown in FIG. 36, the tool body 301 is hollow, the CPUs 306 are sequentially inserted into the inner holes 351, and finally molded with resin. The configuration method is common. A sensor may be inserted in addition to the CPU 306.
As another method, a small-diameter hole 352 is formed in the center of the tool body 301 to allow a signal wire to pass through, and a side surface of the tool body 301 without a blade is selected to form a lateral hole 353 and the CPU 306 is embedded therein. Alternatively, the wiring of the CPU 306 may be extended to the blade base side through the small diameter hole 352.

FIG. 38 shows a circuit system diagram of this embodiment. A ROM 361 and a RAM 362 are attached to each CPU 306 and are connected to each other via a bus 363.
306 is connected to the adjacent CPU 306 by a communication line 365. FIG. 39 is a flowchart showing the contents of processing performed by each CPU 306. (A) shows the processing content of the CPU 306 on the left side (blade edge side), and (b) shows the processing content of the CPU 306 on the right side (blade base side). In each process, when the message from the left side is received,
When 1 is added to the value of the message, the message is sent to the CPU on the right side, and when there is no message from the left side for a certain period of time, the value of the message is reset to 0 and the CP on the right side is reset.
It sends a message to U and repeats this.

Example 8. 40 is a block diagram showing a production apparatus according to an embodiment of the present invention. In the figure,
801 is a machining program including machining information, 802 is analysis means, 803 is command generation means, 804 is drive means, 80
5 is a processing means, 806 is analysis data, 807 is command data, 808 is measurement data, and 809 is a non-program command, which are the same as in the conventional example. Further, reference numeral 810 is a large-capacity storage means for storing the command data 807, which is arranged between the command generation means 803 and the drive means 804.

Next, the operation will be described. First, prior to processing, the analysis unit 802 analyzes the processing program 801 and converts it into analysis data 806. Further, the command generation means 803 creates command data 807 from the analysis data 806 and stores it in the large capacity storage means 810. If there is a program command 809 such as override, the command data is changed. Up to this point, calculation is done offline. Next, at the time of processing, the driving unit 804 controls the drive of the processing machine 805 based on the command data 807 and the measurement data 808 while reading the command data 807 stored in the storage unit 810 online.

According to the production apparatus configured as described above, the on-line calculation by the analysis means 802 and the command generation means becomes unnecessary. Therefore, the calculation time at the time of machining is substantially the time to read the stored command data 807, and as a result, the machining control can be performed at extremely high speed. However, in this case, the non-program instruction 809
Is not processed online, it is not possible to process it in case of abnormality or change the override online. But,
Machining program 80 with no problems in past use
When machining is performed with No. 1, it is rare that an abnormality occurs or the override is changed online, so it is effective when machining is repeatedly performed with the same machining program 801.

Example 9. 41 is a block diagram showing a production apparatus according to another embodiment of the invention of claim 7. In FIG. In the figure, reference numeral 810 is a large-capacity storage means for storing the analysis data 806, which is arranged between the analysis means 802 and the command generation means 803. Other configurations are the same as those shown in FIG. Next, the operation will be described. First, prior to processing, the analysis means 802 performs off-line processing. That is, the analysis unit 802 analyzes the machining program 801, and saves the analysis data 806 in the large-capacity storage unit 810. Next, at the time of processing, the command generating means 803 and the driving means 804 perform online processing. That is, the command generation means 803 causes the storage means 810.
Command data 807 is created based on the analysis data 806 or the non-program command 809 stored in the drive data, and the driving means 804 causes the command data 807 and the measurement data 808.
Drive control of the processing machine 805 is performed in accordance with.

According to the production apparatus configured as described above, since the on-line calculation in the analysis means 802 is unnecessary, the calculation time can be shortened and the command generation means 80 can be shortened.
Since No. 4 performs online processing, it is possible to deal with the non-program instruction 809 online as in the conventional case.

In the seventh and eighth embodiments described above, the command data 807 or the analysis data 806 is stored in the storage means 810 as typical processing control information. You may save the information. For example, it may be used to store intermediate data (not shown) in the analysis unit 802 or the command generation unit 803. In that case, the intermediate data is calculated off-line, the intermediate data is stored in the storage means, and the subsequent calculation is performed online during processing.

Example 10. FIG. 42 is a configuration diagram showing an application example of the eighth embodiment. In the figure, 810 is command data 8
It is a large-capacity storage means for storing 07. Further, driving means 804A, 804B, ... 804N and processing means 805
A, 805B, ..., 805N are provided in pairs and are connected to one storage means 810. The other components are exactly the same as those shown in FIG.

Next, the operation will be described. The off-line calculation part is exactly the same as in the seventh embodiment. On the other hand, in the online calculation part, a plurality of driving means 804A-80
4N is the command data 807 stored in the storage means 810.
While reading, the drive control of each processing means 805A to 805N is performed based on this command data 807 and each measurement data 808A to 808N. According to this production apparatus, a plurality of processing means 805A to 805N
The processing can be controlled in parallel at extremely high speed.

Example 11. FIG. 43 is a configuration diagram showing an application example of the ninth embodiment. Reference numeral 810 is a large-capacity storage means for storing the command data 806. In addition, command generation means 803
A to 803N, driving means 804A to 804N, and processing machines 805A to 805N are provided in pairs and are provided in a plurality.
It is connected to the individual storage means 810. The other components are exactly the same as those shown in FIG.

Next, the operation will be described. The part of the off-line calculation is exactly the same as that of the eighth embodiment. On the other hand, in the online calculation part, a plurality of command generation means 803A-
N generates command data 807A to 807N based on the analysis data 806 stored in the storage unit 810 or the respective non-program instructions 809A to 809N. The drive means 805A to 805N uses this command data 807A.
~ 807N and respective measurement data 808A to 808N
Drive control of each processing means 805A to 805N is performed based on.

According to the production apparatus configured as described above, a plurality of machining means 805A to 805N can be controlled in parallel at a high speed, and the conventional method can be applied to the non-program instructions 809A to 809N. Can be addressed online as well.

Example 12. FIG. 44 is a configuration diagram showing a device in which the device of the eighth embodiment is further embodied. In the figure, 9
Reference numeral 20 denotes a large-capacity hard disk, and the command generation unit 90
7 and the drive unit 910. Other configurations are exactly the same as the conventional example shown in FIG.

Next, the operation will be described. First, prior to processing, the analysis unit 903 analyzes the processing program 901 and converts it into analysis data. Also, the command generation unit 907
Creates command data from the analysis data and the non-program command 915 and stores it in the large capacity hard disk 920. Up to this point, calculation is done offline. Next, at the time of processing, each drive unit 910 reads the command data stored in the hard disk 920 online while controlling the drive of the motor 913 to perform processing on the processing machine 914.

According to the production apparatus configured as described above, the same effect as that described in the eighth embodiment can be obtained. Since the calculation speed of the analysis processor 905 and the command generation processor 908 does not affect the processing time, a low-cost processor with a slow calculation speed may be used. Also,
As long as the machining control device has a function of converting the machining program 901 into command data and storing it in the hard disk 920, it is of course possible to use a device other than the numerical control device, for example, CA.
Various devices such as D / CAM, FA computer, EWS (engineering workstation), and personal computer can be used. In particular, since the calculation speed may be low because the calculation is performed off-line, a device having a low calculation speed can also be used. Therefore, a flexible system can be constructed.

Example 13 FIG. 45 is a block diagram showing a device in which the device of the eighth embodiment is further embodied. In the figure, 9
Reference numeral 20 denotes a large-capacity hard disk, which is arranged between the analysis unit 903 and the command generation unit 907. Other configurations are exactly the same as the conventional example shown in FIG.

Next, the operation will be described. First, prior to processing, the analysis unit 903 uses the offline processing program 9
01 is analyzed, converted into analysis data, and stored in the large capacity hard disk 920. Up to this point, calculation is done offline. Next, during processing, command data is created while reading the analysis data stored in the hard disk 920 online. Alternatively, the non-program instruction 91
If there is 5, the command data is created or changed. Based on this command data, the drive unit 910 causes the motor 91 to
3 is driven and controlled, and processing is performed on the processing machine 914.

According to the production apparatus configured as described above, the same effect as that described in the eighth embodiment can be obtained. Since the calculation speed of the analysis processor 905 does not affect the processing time, a low-cost processor with a slow calculation speed may be used. Further, as long as it is a machining control device having a function of converting the machining program 901 into analysis data and storing it in the hard disk 920, it is needless to say that it is not limited to the numerical control device. For example, CAD / CAM, FA computer, EW.
Various devices such as S and personal computers can be used. In particular,
Since the calculation speed may be slow because it is calculated off-line, equipment with low calculation speed can also be used. Therefore, a flexible system can be constructed.

Example 14. 46 is a block diagram showing a production apparatus according to another embodiment of the invention of claim 7. In FIG. In the figure, 920 is a large-capacity hard disk for storing command data, and 921 is a communication unit. A plurality of sets of the processing machine 914, a drive unit 910 having several drive shafts thereof, and a motor 913 are provided, and are connected to one hard disk 920 through a communication unit 921. Other configurations are exactly the same as the conventional example shown in FIG.

According to the production apparatus configured as described above, it is not necessary to provide one numerical control device for each processing machine 914. Therefore, the production apparatus as a whole can be processed with a simple and inexpensive structure.
Of course, data other than command data may be stored in the large-capacity hard disk 920. In that case, it suffices to provide each processing machine 914 with a portion required for online calculation. In particular, when storing analysis data, each processing machine 914 may be provided with a command data creation unit 907, a drive unit 910 for several control axes, and a motor 913.

Although a hard disk is used as a typical large-capacity storage device in the above, a similar large-capacity storage device such as a RAM, a ROM, an optical disk, or a CD-ROM is used. Has the same effect.

Example 14. FIG. 47 is a configuration diagram of an apparatus in which a CD-ROM 922, a CD-ROM changer 923, and a CD-ROM drive 924 are provided instead of the hard disk. Next, the operation will be described. CD-ROM
CD-R with command data recorded on changer 923
The OM 922 is stocked, and the CD-ROM 922 storing data necessary for processing is inserted into the CD-ROM drive 924. Based on the command data read by the CD-ROM drive 924, the drive unit 910 causes the motor 9
13 is driven and controlled, and processing is performed on the processing machine 914. Prior to processing, the CD-ROM 922 containing the necessary information does not even require offline calculation and is stored in the CD-ROM changer 923.
Just set it to. The CD-ROM 922 is classified and used for each processing machine, tool, work, shape or type of processing, for example.

In the fourteenth embodiment, the first embodiment is also used.
It is also possible to control a plurality of processing machines 914 at the same time based on the storage data of the CD-ROM 922 as in the case of 3. It goes without saying that the processing control information other than the command data may be stored in the CD-ROM 922.
