Hereinafter, the machine tool of each embodiment will be described with reference to the accompanying drawings. The machine tool of each embodiment is exemplified by a machine tool including a laser beam machine. The laser processing machine here is a laser cutting processing machine that cuts a material with a laser. The material is, for example, a metal plate material.

The machine tool of each embodiment may be configured to include an arbitrary processing machine that processes materials. The processing machine may be a laser welding machine, a punching machine, a bending machine, a band saw machine or the like in addition to the laser cutting machine.

First, an example of the overall configuration of the machine tool of each embodiment will be described with reference to FIG. In FIG. 1, an NC device 2 for controlling the laser processing machine 1 is connected to the laser processing machine 1. Connected to the NC device 2 are a display unit 3 capable of displaying various types of information regarding the machine tool (laser processing machine 1) and an operation unit 4 for operating the laser processing machine 1.

The operation unit 4 may be a touch panel arranged on the display unit 3. The operation unit 4 may be an operation unit including a general operation button to be pressed. The operation unit 4 may include both operation buttons and a touch panel. In the present embodiment, it is assumed that the operation unit 4 is a touch panel.

A server device 5 and a CAM 6 are connected to the NC device 2. The server device 5 and the CAM 6 may be integrally configured.

The server device 5 collects and stores data indicating the operation status of the machine tool from the NC device 2 as described later. The CAM 6 stores various data necessary for processing the material. One of the data stored in the CAM 6 is data related to the board cutting when a product is cut out from the board material.

The NC device 2, the server device 5 and the CAM 6 may be connected via a network. The laser processing machine 1 and the NC device 2, the server device 5, and the CAM 6 may be installed at locations away from each other.

The operation display unit 7 is connected to the server device 5. As will be described later, the operation display unit 7 can display the operation status of the machine tool. As an example, it is assumed that the operation display unit 7 is a liquid crystal panel with a touch panel. The operation display unit 7 may be a tablet terminal.

The server device 5 and the operation display unit 7 may be connected by wire or may be connected wirelessly. The CAM 6 may include an operation unit or a display unit.

A schematic internal configuration example of the laser beam machine 1 will be described with reference to FIG. As shown in FIG. 2, the laser processing machine 1 includes a laser oscillator 11, a processing machine main body, a chiller 13 that is a water cooling device, and a dust collector 14.

The processing machine body 12 includes a servo mechanism 121, an actuator 122 for moving each part of the processing machine body 12, and an assist gas ejection unit 123. The servo mechanism 121 includes a motor.

The actuator 122 is moved by the air supplied from the compressor 1220 provided outside the laser processing machine 1. Assist gas is supplied to the assist gas ejection unit 123 from an assist gas supply unit 1230 provided outside the laser processing machine 1.

The chiller 13 is connected with a power meter 131 that measures the amount of power consumed when the chiller 13 operates. The dust collector 14 is connected to a wattmeter 141 that measures the amount of power consumed when the dust collector 14 operates.

The NC device 2 can calculate the power consumption when each unit such as the laser oscillator 11 and the servo mechanism 121 operates by calculation. Therefore, the NC device 2 can also obtain power consumption when each unit not connected to the

wattmeters

131 and 141 operates.

There is a part where the power consumption does not fluctuate so much depending on the operating conditions of the laser beam machine 1. For portions other than the laser oscillator 11 and the servo mechanism 121 where the power consumption does not vary so much, the power consumption can be regarded as a substantially constant value. The NC device 2 stores in advance a constant value indicating the power consumption amount of the portion where the power consumption amount does not vary so much. The NC device 2 considers the power consumption of the NC device 2 itself to be a constant value and holds it.

In FIG. 2,

power meters

131 and 141 are connected only to the chiller 13 and the dust collector 14, but instead of the NC device 2 calculating the power consumption by calculation, the power consumption may be measured by the power meter. .

As described above, the NC device 2 can obtain the power consumption of the machine tool when the machine tool operates. In each embodiment, the power consumption of the NC device 2 and the laser processing machine 1 is the power consumption of the entire machine tool. Of course, the total power consumption including other portions may be calculated.

The NC device 2 can cause the display unit 3 to display power consumption and a power charge when the machine tool operates.

Specifically, as shown in FIG. 3A, the NC device 2 displays instantaneous power information 301 indicating instantaneous power on the display unit 3 when a predetermined operation is performed by the operation unit 4. When the operator touches the position of the instantaneous power information 301, as shown in FIG. 3 (b), the NC device 2 displays the current power usage information on the current day instead of the instantaneous power information 301 on the display unit 3. 302 is displayed.

When the operator touches the position of the power usage information 302 on the current day, the NC device 2 displays the standby power fee indicating the standby power fee on the display unit 3 instead of the power usage information 302 on the current day, as shown in FIG. Information 303 is displayed.

The NC device 2 holds a conversion formula for converting the amount of power into a power rate. The NC device 2 can display the standby power charge information 303 by measuring the time when the laser beam machine 1 is in the standby state and obtaining the power consumption amount.

The NC device 2 may cause the display unit 3 to simultaneously display an arbitrary plurality of the instantaneous power information 301, the current day power usage information 302, and the standby power rate information 303.

Hereinafter, the information which makes the operator aware of the resource saving that the machine tool of each embodiment presents will be specifically described.

<First Embodiment>
The NC device 2 responds to a predetermined operation input to the operation unit 4 when processing the plate material by the laser processing machine 1, and displays the operation status information 304 on the display unit 3 as shown in FIG. Display. The operation status information 304 includes processing time, amount of power used, amount of assist gas, amount of air supplied to the actuator 122 by the compressor 1220, consumables cost, and maintenance cost.

Processing time, power consumption, amount of assist gas, and amount of air differ depending on the material and thickness of the plate material to be processed and depending on what kind of processing is performed on the plate material. The NC device 2 can calculate each value by obtaining data relating to the plate material and data relating to the processing applied to the plate material from the CAM 6.

Preferably, the NC device 2 converts the amount of power used, the amount of assist gas, and the amount of air into costs and displays them in the operation status information 304. The NC device 2 holds a conversion formula for converting the amount of assist gas and the amount of air into costs.

The laser processing machine 1 includes consumables that are exchanged in a relatively short period such as a lens, a mirror, and a filter, and consumables that are exchanged in a relatively long period such as an electrode inside the pump and the laser oscillator 11. The owner of the machine tool may have a maintenance contract for maintaining and managing the machine tool.

Therefore, the NC device 2 calculates the cost of the consumables corresponding to the machining time, and causes the display unit 3 to display the consumables cost as one item of the operation status information 304. For example, if the consumables are determined to be replaced in one year, the consumables cost corresponding to the cost of using the consumables only for the processing time is calculated by the calculation of (consumables cost) x processing time / year. Can be calculated.

The NC device 2 calculates the maintenance cost for the machining time and causes the display unit 3 to display it as one item of the operation status information 304. Similarly, since the maintenance cost is determined, for example, in one year, the maintenance cost for the machining time can be calculated.

Thus, in the first embodiment, not only the amount of power used and the amount of resources necessary for processing (here, assist gas and air), but also the consumables and maintenance costs that are actually incurred are reduced. It is displayed as an item of the operation status information 304. The operation status information 304 may be displayed on a display unit included in the CAM 6.

The operation status information 304 may be only consumables costs and maintenance costs. The operation status information 304 may be only one of consumables costs and maintenance costs. The machine tool of the first embodiment for displaying the consumables cost and the maintenance cost on the display unit 3 can be realized by configuring the NC device 2 as shown in FIG.

As shown in FIG. 5, the NC device 2 functionally includes a cost calculation unit 21 that calculates consumables costs or maintenance costs, and a display control unit that controls the display unit 3 to display the consumables costs or maintenance costs. 22. The cost calculation unit 21 and the display control unit 22 can be configured by software modules.

If the consumables cost or maintenance cost is low, it will result in resource saving. According to the first embodiment, the operator can be more aware of resource saving. Further, according to the first embodiment, it is possible to make the operator aware of cost.

In the first embodiment, when the machine tool is operated to process a plate material, the operation status information 304 is displayed on the display unit 3. After processing the plate material, the resulting operation status information 304 may be displayed on the display unit 3.

In the first embodiment, the cost calculation unit 21 calculates the consumables cost or the maintenance cost corresponding to the processing time for the laser processing machine 1 to process the plate material. The time for calculating the consumables cost and the maintenance cost is not limited to the processing time. The cost calculation unit 21 may calculate a consumable cost or a maintenance cost when the laser processing machine 1 is operated for a predetermined time or when it is operated for a predetermined time.

Second Embodiment
As shown in FIG. 6, the NC device 2 can compare the machine that is processing the plate material with a comparator that is another model when trying to process the plate material with the laser processing machine 1. The operation status information 305 is displayed.

The operation status information 305 includes the processing time, the amount of power used, the amount of assist gas, the amount of air, the cost of consumables, and the maintenance cost, like the operation status information 304. The operation status information 305 may not include all of these, and may include any one or more items.

CAM 6 holds data for calculating the processing time, the amount of power used, the amount of assist gas, the amount of air, the cost of consumables, and the maintenance cost when this machine and the comparator are operated. Therefore, the NC device 2 or the CAM 6 can calculate each value when the same processing as the processing to be performed on the plate material by this machine is performed by the comparator.

For example, when the owner of this machine also owns the comparator, the operator can select a machine tool with a shorter machining time or a machine tool that can be machined at a lower cost. Therefore, according to the second embodiment, the operator can be more aware of resource saving. Further, according to the second embodiment, it is possible to make the operator aware of cost.

Also, even when the owner of this machine does not own the comparator, it is possible to promote replacement with a machine tool that can save more resources.

Similarly, in the second embodiment, after the machine tool is operated to process the plate material, the resulting operation status information 305 may be displayed on the display unit 3. The operation status information 305 may be displayed on the display unit included in the CAM 6.

The machine tool of the second embodiment that displays the operation status information 305 on the display unit 3 can also be realized by configuring the NC device 2 as shown in FIG.

The cost calculation unit 21 operates the machine tool to perform predetermined processing on the plate material, or when the predetermined processing is performed, when the predetermined processing is performed on the plate material, The second cost required when a predetermined processing is performed on the plate material by the comparator is calculated. The display control unit 22 causes the display unit 3 to display the first cost and the second cost.

As mentioned above, according to 2nd Embodiment, it is a machine tool provided with the processing machine which processes material, and the machine tool provided with a cost calculation part and a display control part is provided.

<Third Embodiment>
The laser processing machine 1 has three states: an operation state that is actually operating to process a plate material, standby information that is waiting for processing, and a stop state in which the operation is stopped for some reason. Take. When the operator operates the stop button to stop the operation of the laser beam machine 1, the laser beam machine 1 is stopped. Further, when an alarm is generated and the laser processing machine 1 automatically stops its operation, the laser processing machine 1 is stopped.

The NC device 2 always supplies the server device 5 with data indicating whether the laser processing machine 1 is in an operating state, standby information, or a stopped state. The server device 5 continuously collects the state of the laser processing machine 1.

As illustrated in FIG. 7, the server device 5 generates, for example, operation status information 701 indicating the operation status of the laser processing machine 1 for one month, and displays the operation status information 701 on the operation display unit 7. When a specific day is specified by the operation display unit 7, the server device 5 generates operation status information 702 indicating the operation status of the specified day and displays the operation status information 702 on the operation display unit 7.

FIG. 7 shows that the data on October 17 in the operation status information 701 is displayed by, for example, a thick solid line and that October 17 is designated. The operation status information 702 indicates an operation time, a standby time, and a stop time on the first day of October 17th.

As shown in FIG. 8, the server device 5 may further cause the operation display unit 7 to display operation status information 703 indicating the standby power charge for this month (October in this case) and the processing power charge. The calculation of the standby power charge and the processing power charge may be performed by the server device 5 or the NC device 2. The CAM 6 may calculate the standby power charge and the processing power charge.

As shown in FIGS. 7 and 8, it is preferable to know the reason for the stop state when the

operation status information

701 and 702 are displayed on the operation display unit 7. If the reason for the stop state is known, the stop state can be shortened as much as possible, preferably the stop state can be eliminated, and the laser beam machine 1 can be operated efficiently. Efficient operation contributes to resource saving.

When an alarm is generated in the laser processing machine 1 and the machine is stopped, data indicating that the alarm has occurred is supplied from the NC device 2 to the server device 5. Therefore, the server device 5 can display the fact that the operation display unit 7 has been stopped due to an alarm.

However, when the laser beam machine 1 is stopped for a reason other than an alarm, the server device 5 cannot know the cause. Therefore, in the third embodiment, the operator operates the operation display unit 7 to register the cause of the laser processing machine 1 being stopped in the server device 5. The operator can cause the server apparatus 5 to register images such as option information, memos, and photographs that record the current situation.

When the operator stops the laser beam machine 1, the operator executes an input operation for the following cause. In response to a predetermined operation input to the operation display unit 7, the operation display unit 7 displays option information 704 for selecting the cause as shown in FIG.

The options shown in FIG. 9 are merely examples, and the operator can add new options, correct options, and delete unnecessary options. For example, when the assist gas is exhausted and the laser beam machine 1 is stopped, the operator selects “out of gas” from the options and touches the determination button 705 to determine the option.

Thereby, the cause of the laser processing machine 1 being stopped is registered in the server device 5. The information for confirming the cause as described above may be a memo or an image, or a combination thereof. If there are multiple stop states a day, the server device 5 may store, for example, the time during which the stop state is established and the time when the cause is registered. The method of associating each stop state with the cause is arbitrary.

When the operator performs an operation for confirming the cause of the operation display unit 7 being stopped, the operation display unit 7 reads data indicating the cause from the server device 5 and causes the operation display unit 7 to display the data.

As an example, when the operator touches a bar graph indicating the stop time of the operation status information 702, the cause is displayed on the operation display unit 7. As shown in FIG. 10, the operation display unit 7 displays the cause (here, out of gas) by, for example, a balloon.

If there are multiple stop states with different causes, it is also possible to display each stop state and cause in correspondence.

The machine tool of the third embodiment can be realized by configuring the server device 5 as shown in FIG. As shown in FIG. 11, the server device 5 functionally includes a totaling unit 51 and a registration unit 52. The totaling unit 51 and the registration unit 52 can be configured by software modules.

The counting unit 51 is within a predetermined period of time that the laser processing machine 1 is in an operating state for processing a plate material, and a standby time in which the laser processing machine 1 is in a standby state waiting for processing of the plate material. And the stop time when the operation is stopped are counted. The registration unit 52 registers the cause of the laser processing machine 1 being stopped.

The server device 5 supplies the operation display unit 7 with data indicating the counting result or the cause. The operation display unit 7 displays the total result or cause on the display unit. The counting result and the cause may not be displayed on the operation display unit 7 at the same time.

Here, since the operation display unit 7 has a display control unit, the server apparatus 5 may supply the operation display unit 7 with data indicating the total result or cause. You may provide the server apparatus 5 with the display control part which displays a total result and a cause on a predetermined | prescribed display part.

As described above, in the third embodiment, the operator can register the cause of the stop state in the server device 5 and confirm the cause by, for example, the operation display unit 7.

According to the third embodiment, the laser beam machine 1 can be operated efficiently with fewer stopped states. Therefore, according to the third embodiment, the operator can be more aware of resource saving.

The NC device 2 may cause the display unit 3 to display each piece of information shown in FIG. 7, FIG. 8, and FIG. The display unit that displays each piece of information illustrated in FIGS. 7, 8, and 10 is not limited to the operation display unit 7.

As described above, according to the third embodiment, the processing machine that processes the material, the counting unit that counts the operation time, the standby time, and the stop time within a predetermined period, and the processing machine are in a stopped state. There is provided a machine tool including a registration unit for registering a cause, and a display unit for displaying a totaling result and a cause by the totaling unit.

<Fourth embodiment>
When a predetermined product is cut out from a plate material, if the yield rate is low, the remaining material may be wasted. In consideration of resource saving, it is desirable to be able to confirm how much waste is generated when trying to process a plate material.

As shown in FIG. 12, the NC device 2 displays on the display unit 3, cutting information 306 indicating how the product is cut on the plate, and cost information 307 corresponding to the cutting information 306. Let It is also possible to display the planing information 306 and the cost information 307 on the display unit included in the CAM 6.

The plate cutting information 306 indicates a plate cutting state of the product P with respect to the plate material Ws. Here, a case is shown in which 16 products P having the shape shown in the figure are cut out from the plate material Ws. The NC device 2 can display the planing information 306 on the display unit 3 by reading data related to the planing from the CAM 6.

The NC device 2 holds information on the unit price and scrap price for each material of the plate material Ws. The NC device 2 can obtain data on the area and thickness of the plate material Ws from the CAM 6. The NC device 2 can obtain data indicating the yield rate from the CAM 6. Here, it is assumed that the yield rate is 60%.

As an example, the NC device 2 calculates the price of the plate material Ws as 10,000 yen. Since the yield rate is 60%, the remaining material price is 4,000 yen.

When the NC device 2 displays the cost information 307 including the remaining material price on the display unit 3, the operator can recognize how much is wasted.

The cost information 307 preferably includes a scrap price when the remaining material is sold as scrap. The NC device 2 calculates the scrap price as, for example, 300 yen. The NC device 2 causes the display unit 3 to display cost information 307 including the remaining material price and the scrap price.

When the NC device 2 displays the cost information 307 including the remaining material price and the scrap price on the display unit 3, even if the operator of the NC device 2 sells the remaining material, the difference between the remaining material price and the scrap price is useless. Can be recognized. If the cost information 307 is displayed on the display unit of the CAM 6, the operator of the CAM 6 can recognize the same thing.

The machine tool of the fourth embodiment can be realized by configuring the NC device 2 as shown in FIG. In FIG. 13, the same parts as those in FIG.

As shown in FIG. 13, the NC device 2 functionally includes a price calculation unit 23 and a display control unit 22. The price calculation unit 23 can be configured by a software module. The price calculation unit 23 calculates the remaining material price based on the price of the plate material and the yield rate when one or more products are cut out from the plate material. The price calculation unit 23 preferably calculates a scrap price in addition to the remaining material price.

The display control unit 22 displays the remaining material price on the display unit 3. Preferably, the display control unit 22 causes the display unit 3 to display a scrap price in addition to the remaining material price.

According to the fourth embodiment, the operator can be more aware of resource saving. Further, according to the fourth embodiment, it is possible to make the operator aware of cost.

The display unit for displaying the planing information 306 and the cost information 307 shown in FIG. 12 is not limited to the display unit 3 and may be displayed on the display unit included in the CAM 6 as described above. The remaining material price and scrap price calculated by the price calculation unit 23 of the NC device 2 may be supplied to the CAM 6, or the CAM 6 may calculate the remaining material price and scrap price.
