The carbon dioxide emissions of the target machine are estimated based on the predicted processing time.

According to this configuration, the calculation unit can replace the machining conditions of the actual machining machine with the machining conditions of the target machine, and then analyze the machining program used by the actual machining machine.

This carbon dioxide emission estimation system 1 includes an actual processing machine 2, a processing program DB4, a processing condition DB5, a target machine DB6, a performance DB7, a control device 8, a display device 9, and an input device 10.

The actual processing machine 2 is a processing machine that actually performs processing. In this embodiment, the actual processing machine 2 is a laser processing machine (laser cutting processing machine) that cuts a workpiece using a laser beam. The actual processing machine 2 is, for example, a fiber laser processing machine.

The actual processing machine 2 is provided with a power meter 20 that measures the amount of power consumed by the actual processing machine 2. The power meter 20 measures the amount of power consumed by a processing machine main body including a processing head that irradiates a laser beam, a moving mechanism that moves the processing head, and peripheral devices such as a laser oscillator.

The machining program DB4 stores a machining program for the actual machining machine 2 to cut a workpiece. FIG. 2 is an explanatory diagram showing a machining program. In the machining program, a plurality of codes, which are control instructions for controlling the actual machining machine 2, are written line by line. Each code includes a series of instructions for the actual processing machine 2 from the start of processing to the end of processing, such as setting processing conditions, starting laser beam injection, processing feed, stopping laser beam injection, and moving the processing head to the piercing position. The behavior is defined. The code written in the machining program includes a unique number called an E number (machining condition number), and the machining condition is specified by this machining condition number.

The actual processing machine processing condition DB5 stores processing conditions used for laser processing by the actual processing machine 2. The processing conditions are set for each actual processing machine 2, and if the type of actual processing machine 2 is different, the processing conditions will also be different. The processing conditions include at least the type of oscillator, specification of the focusing lens, nozzle type, nozzle diameter, material and thickness of the workpiece, processing method, processing speed, piercing time, laser output, pulse frequency, pulse duty, focal position, etc. Information is mentioned.

Information regarding the machining conditions of the actual machining machine 2 is mapped in a data table together with machining condition numbers. The machining conditions are called from the machining condition data table and made available when the control device 8 decodes the code (machining condition number) written in the machining program.

The target machine DB 6 stores data related to the target machine 3, which is a processing machine that is subject to a trial calculation of carbon dioxide emissions, which will be described later. The target machine 3 is a different type of processing machine from the actual processing machine 2 (a different type of processing machine that performs the same type of processing (for example, cutting processing)). The target machine 3 is, for example, a CO ₂ laser processing machine. The target machine DB6 stores processing conditions and machine parameters used for laser processing of the target machine 3. The processing machine parameters are parameters used by the control device 8 to control the target machine 3, and are parameters unique to the target machine 3.

The track record DB 7 is a database that manages the processing track record of the actual processing machine 2, estimated carbon dioxide emissions, and the like.

The control device 8 is configured by a computer having a hardware processor such as a CPU (Central Processing Unit), a memory, and various interfaces. Memory and various interfaces are connected to the hardware processor via a bus. Various functions are realized by causing a hardware processor to execute programs stored in memory.

In this embodiment, the control device 8 is a control device that controls the actual processing machine 2. The control device 8 includes a processing control section 80 and a calculation section 81.

The processing control section 80 controls the operation of the actual processing machine 2. Specifically, the machining control unit 80 executes a machining program and controls the operation of the actual machining machine 2 using NC (Numerical Control). The operation of the actual processing machine 2 is controlled according to a processing program and processing conditions read out according to the processing program.

The calculation unit 81 estimates the amount of carbon dioxide emitted when the target machine 3 performs processing according to the processing program used by the actual processing machine 2 . The calculation unit 81 can acquire various information held by the actual processing machine 2 by communicating with the actual processing machine 2 . This information includes the amount of power consumption measured by the wattmeter 20, and the like. Note that the calculation unit 81 may be realized by an independent computer without being incorporated into the control device 8.

The display device 9 is a device for displaying various information.

The input device 10 is a device for inputting information to the control device 8.

Hereinafter, with reference to FIG. 3, a carbon dioxide emission estimation method according to the present embodiment will be described. FIG. 3 is a flowchart showing the process for calculating the amount of carbon dioxide emissions. The processing shown in this flowchart is executed by the control device 8.

First, in step S10, the processing control section 80 executes processing. At this time, the machining control unit 80 reads the machining program used for machining the workpiece from the machining program DB 4, and executes the read machining program. The actual processing machine 2 operates according to a processing program and processing conditions read out according to the processing program, and performs a predetermined laser cutting process on the workpiece. When the machining program is executed by the machining control unit 80, the calculation unit 81 acquires and holds the time and power consumption at the time of execution each time the machining control unit 80 executes one line of code. When the machining is completed, the process moves to step S11.

FIG. 4 is a diagram illustrating the process of searching the target machine DB. In step S11, the calculation unit 81 searches the target machine DB 6, and finds machining conditions 50 of the actual machining machine 2 when the actual machining machine 2 performs machining according to the machining program (hereinafter referred to as "actual machining machine machining conditions 50"). It is determined whether there is a machining condition 60n of the target machine 3 (hereinafter referred to as "target machine machining condition 60n") that is common to the target machine 3.

Specifically, the calculation unit 81 searches the target machine DB 6 and determines whether there is a target machine processing condition 60n that satisfies the following three requirements.
(Requirement 1) The material of the workpiece matches the actual processing machine processing condition 50.
(Requirement 2) Matches the processing method of actual processing machine processing conditions 50.
(Requirement 3) The maximum plate thickness of the workpiece within the target machine processing conditions 60n is greater than or equal to the plate thickness of the workpiece under the actual processing machine processing conditions 50.

If there is no target machine processing condition 60n that satisfies the above three requirements (No in step S11), the calculation unit 81 ends the process shown in this flowchart.

On the other hand, when the above three requirements are satisfied, the calculation unit 81 performs a detailed search. Specifically, the calculation unit 81 searches for target machine processing conditions 60n that satisfy the following three requirements.
(Requirement a) Matches the workpiece thickness of the actual processing machine processing condition 50.
(Requirement b) Matches the nozzle type of actual processing machine processing condition 50.
(Requirement c) Matches the nozzle diameter of actual processing machine processing condition 50.

Note that even if the workpiece thickness under the actual machine processing conditions 50 and the workpiece thickness under the target machine processing conditions 60n do not completely match, the calculation unit 81 determines that the workpiece thickness satisfies the following requirement a1. The described target machine processing conditions 60n are treated as satisfying requirement a.
(Requirement a1) It is larger than the plate thickness of the workpiece under the actual processing machine processing conditions 50, and is the closest value to the workpiece thickness under the actual processing machine processing conditions 50.

If there is a target machine machining condition 60n that satisfies the three requirements from requirement a to requirement c (Yes in step S11), the calculation unit 81 moves to the process of step S12. On the other hand, if there is no target machine processing condition 60n that satisfies the three requirements from requirement a to requirement c (No in step S11), the calculation unit 81 ends the process shown in this flowchart.

In step S12, the calculation unit 81 extracts target machine processing conditions 60n that satisfy the above requirements.

In step S13, the calculation unit 81 determines whether or not the machining of the actual machining machine 2 has abnormally ended midway. If the machining of the actual machining machine 2 abnormally ends midway through, the calculation unit 81 proceeds to the process of step S14. On the other hand, if the machining by the actual machining machine 2 has been completed normally, the calculation unit 81 skips the process of step S14 and proceeds to the process of step S15.

In step S14, the calculation unit 81 identifies the last executed code among the codes written in the machining program.

Then, the calculation unit 81 predicts the machining time required for the target machine 3 to perform machining, assuming that the machining program is executed using the extracted target machine machining conditions 60n.

Specifically, the control device 8 divides each line of code written in the machining program into machining condition numbers. Then, the control device 8 analyzes the machining program and calculates the machining time for each divided code. In calculating the machining time, the length of the path for cutting the part, the number of piercings, the number of times multiple pieces are cut out to cut out a large number of the same part, etc. are taken into consideration.

The control device 8 can calculate the machining time required for cutting each part by multiplying the path length related to cutting the part by the cutting speed of the machining conditions. The control device 8 can calculate the processing time required for piercing by multiplying the number of piercings by the piercing time of the processing conditions. Furthermore, the control device 8 can calculate the machining time required for cutting multiple parts by multiplying the machining time required for cutting one part by the number of executions for multiple part machining.

At this time, the calculation unit 81 analyzes the machining program by replacing the actual machining machine machining conditions 50 with the target machine machining conditions 60n extracted in step S11. Therefore, the calculation unit 81 performs the above calculation based on the machining speed and piercing time described in the target machine machining conditions 60n.

The calculation unit 81 analyzes all the codes written in the machining program, from the first line of code to the last line of code, and performs the above calculation. Then, the calculation unit 81 predicts the machining time when the target machine 3 performs machining according to the machining program from the sum of all the calculated machining times.

In addition, if the machining of the actual machining machine 2 terminates abnormally in the middle, the calculation unit 81 analyzes the code from the first line of code written in the machining program to the last executed code. , perform the above calculation.

In step S16, the calculation unit 81 calculates the amount of power consumed by the target machine 3 during the machining time based on the predicted machining time and the parameters of the target machine 3. The parameter of the target machine 3 is the amount of power consumed by the target machine 3 per second, and is described in the target machine parameters of the target machine DB6.

In step S17, the calculation unit 81 estimates the carbon dioxide emissions of the target machine 3 based on the calculated power consumption. The arithmetic unit 81 holds an arithmetic formula or map for converting power consumption into carbon dioxide emissions, and uses this arithmetic formula or map to estimate the carbon dioxide emissions.

In step S18, the calculation unit 81 calculates the carbon dioxide emissions of the actual processing machine 2 during the period from when the actual processing machine 2 starts machining to when it ends, based on the power consumption measured by the wattmeter 20. calculate. Specifically, the calculation unit 81 subtracts the power consumption at the timing when the actual processing machine 2 starts machining from the power consumption at the timing when the actual processing machine 2 finishes machining (including abnormal termination). Calculate the power consumption. Then, the calculation unit 81 calculates the carbon dioxide emissions of the actual processing machine 2 based on the calculated power consumption.

In step S19, the calculation unit 81 manages the carbon dioxide emissions of the target machine 3 and the carbon dioxide emissions of the actual processing machine 2, as well as the machining results. At this time, the calculation unit 81 manages the carbon dioxide emissions of the target machine 3 and the carbon dioxide emissions of the actual processing machine 2 for each processing program, sheet, and part based on the analysis results of the processing program. can do. The carbon dioxide emissions of the target machine 3 and the carbon dioxide emissions of the actual processing machine 2, organized by machining program, sheet, and part, are recorded in the performance DB 7.

FIG. 5 is a diagram showing the amount of carbon dioxide emissions displayed on the display device. In step S20, the calculation unit 81 compares the carbon dioxide emissions of the target machine 3 and the actual processing machine 2 on the display device 9 based on the information stored in the performance DB 7. indicate. For example, as shown in FIG. 5, the calculation unit 81 displays the carbon dioxide emissions of the target machine 3 and the carbon dioxide emissions of the actual processing machine 2 vertically in the first display area 90 of the display device 9. It is as if to do so.

In addition, the calculation unit 81 displays, in the second display area 91 of the display device 9, the carbon dioxide emissions of the target machine 3 and the carbon dioxide emissions of the actual processing machine 2, along with the processing results, based on the information stored in the performance DB 7. Display carbon emissions. For example, the calculation unit 81 displays the carbon dioxide emissions of the target machine 3 and the actual processing machine 2 together with the processing results for each sheet.

Note that FIG. 5 shows a display example when the "sheet" tab is selected by the input device 10. When the "Parts" tab is selected by the input device 10, the calculation unit 81 displays the carbon dioxide emissions of the target machine 3 and the actual processing machine 2 along with the processing results for each part. You can also.

Predict. The calculation unit 81 estimates the carbon dioxide emissions of the target machine 3 based on the predicted machining time.
