The machine tool of one embodiment is exemplified by a laser processing machine that cuts a metal material (for example, a plate material) with a laser. The machine tool may be an arbitrary machine tool such as a laser welding machine or a bending machine in addition to a laser beam machine.

  First, an example of the overall configuration of a machine tool will be described with reference to FIG. In FIG. 1, a display device 30, a mechanical operation switch 40, and a machine main body 50 are connected to the NC device 10.

  The NC device 10 is a control unit that controls the machine main body unit 50 and other units. The NC device 10 includes an operation setting unit 11 that sets and holds an operation in the machine main body unit 50 and a storage unit 20.

  The storage unit 20 stores a processing program MP for processing a material by the machine main body unit 50. The storage unit 20 is a rewritable nonvolatile memory, for example.

  The display device 30 is a liquid crystal panel, for example. A touch panel 31 is attached to the display device 30. In the machine tool of the present embodiment, an operation switch based on an image for operating the machine main body 50 or setting an operation in the machine main body 50 is displayed on the display device 30, and the operation switch is operated by the touch panel 31. I have to.

  In FIG. 1, the size of the touch panel 31 is smaller than the screen of the display device 30, but the touch panel 31 may be attached to the entire screen of the display device 30.

  When all the operation switches are operated by the touch panel 31, the mechanical operation switch 40 can be omitted. The machine tool of this embodiment may or may not include the mechanical operation switch 40.

  The machine main body 50 includes a processing related operation unit 51 that performs operations related to material processing, and a processing non-related operation unit 52 that is not directly related to material processing. An example of the processing unrelated operation unit 52 is a work lamp provided in the machine main body unit 50.

  The processing related operation unit 51 has, for example, a configuration as shown in FIG. As shown in FIG. 2, the machining-related operation unit 51 includes a movement axis 511 composed of an X axis and a Y axis for moving the material on the XY plane, and a Z axis for moving the laser head (not shown) up and down. And a shaft drive unit 512 for driving the moving shaft 511.

  The processing related operation unit 51 may be configured such that the material is fixed and the laser head moves.

  The processing related operation unit 51 includes a shutter 513 for enabling output of laser light from the laser head, and a shutter drive unit 514 for driving the shutter 513. The processing related operation unit 51 includes a pallet 515 on which a material is placed, and a pallet driving unit 516 that moves the pallet 515 in a plane or vertically.

  The shaft driving unit 512, the shutter driving unit 514, and the pallet driving unit 516 are controlled by the NC device 10.

  Returning to FIG. 1, the operation setting unit 11 sets the lighting or extinguishing state of the work lamp in the machining unrelated operation unit 52. The operation setting unit 11 sets whether or not the machining program MP is to be a single block that causes the machining-related operation unit 51 to execute line by line. The operation setting unit 11 can set an automatic power-off that shuts off the power of the machine main body 50 at a predetermined time.

<First example>
First, a first example of the touch panel 31 will be described. In the first example, the touch panel 31 is configured as shown in FIG. As shown in FIG. 3, the touch panel 31 is provided with two regions, a low sensitivity region 31L and a high sensitivity region 31H. The low sensitivity region 31L is a first operation region having a first sensitivity. The high sensitivity region 31H is a second operation region having a second sensitivity that is higher than the first sensitivity.

  It can be said that the low sensitivity region 31L is a region that requires a relatively long time to operate and requires a reliable operation. The high-sensitivity region 31H can be said to be a region that can be operated in a relatively short time and can be operated lightly. High or low sensitivity means lightness and ease of operation.

  As the touch panel 31, for example, a resistive film type touch panel or a capacitance type touch panel can be used. The NC device 10 detects whether or not a finger or the like has touched the touch panel 31 based on an output signal from the touch panel 31. The NC device 10 can set the low sensitivity region 31L and the high sensitivity region 31H by setting the sensitivity when detecting contact with a finger or the like in two stages by software.

  When the touch panel 31 is a resistive film type touch panel, the time until it is detected that the touch panel 31 is touched is set to a relatively long first time and a relatively short second time. The sensitivity region 31L and the high sensitivity region 31H can be set.

  When the touch panel 31 is a capacitive touch panel, the capacitance value until it is detected that the touch panel 31 is touched is set to a relatively large first value and a relatively small second value. Thus, the low sensitivity region 31L and the high sensitivity region 31H can be set.

  In general, a capacitive touch panel is more sensitive than a resistive touch panel. Therefore, a resistive touch panel may be used for the low sensitivity region 31L, and a capacitive touch panel may be used for the high sensitivity region 31H.

  A method of setting two sensitivity areas on the touch panel 31 is arbitrary. The touch panel 31 should just have the low sensitivity area | region 31L and the high sensitivity area | region 31H from which sensitivity differs mutually by arbitrary methods. The left and right positions of the low sensitivity region 31L and the high sensitivity region 31H may be reversed or may be aligned vertically.

  As shown in FIG. 4, the display device 30 displays the first operation switches (S1L, S2L, S3L, S4L) that are operation switches based on images and assigned to the function of operating the machining-related operation unit 51. ing. Further, the display device 30 displays the second operation switches (S5H, S6H, S7H, S8H, S9H) which are operation switches based on images and assigned to functions other than the function for operating the processing related operation unit 51. ing.

  The operation switches based on these images are configured to be operated by the touch panel 31.

  The second operation switch assigned to a function other than the function for operating the machining-related operation unit 51 is an operation switch for setting the operation in the machine main body unit 50 in the operation setting unit 11 or a processing non-related operation unit 52. It is an operation switch for operating. Since the operation setting unit 11 holds operation setting information, the machining-related operation unit 51 is not operated by the operation setting.

  In FIG. 4, a start switch S1L, a jog feed switch S2L, a shutter switch S3L, and a palette switch S4L are displayed in a display area (first display area) corresponding to the low sensitivity area 31L. These operation switches are examples of a first operation switch that is displayed in a display area corresponding to the low sensitivity area 31L.

  When the start switch S1L is operated, the NC device 10 starts the operation of the machine body 50. The start switch S1L may be an operation switch that starts processing the material by the machine main body 50. When the jog feed switch S <b> 2 </ b> L is operated, the NC device 10 controls the shaft driving unit 512 to operate the moving shaft 511.

  When the shutter switch S3L is operated, the NC apparatus 10 controls the shutter driving unit 514 to open the shutter 513 so that the laser light from the laser head can be output. When the pallet switch S4L is operated, the NC apparatus 10 controls the pallet driving unit 516 to move the pallet 515.

  In FIG. 4, the display area (second display area) corresponding to the high sensitivity area 31H includes a single block setting switch S5H, an automatic power-off setting switch S6H, a time setting switch S7H, a work light switch S8H, and an emergency stop. Switch S9H is displayed. These operation switches are examples of the second operation switch displayed in the display area corresponding to the high sensitivity area 31H.

  When the single block setting switch S5H is operated, the NC apparatus 10 sets the operation setting unit 11 to set the operation in the machining related operation unit 51 to a single block. When the automatic power-off setting switch S6H is operated, the NC device 10 sets the operation setting unit 11 to cut off the power of the machine main body 50 at a predetermined time. When the time setting switch S7H is operated, the NC apparatus 10 sets the time of automatic power-off and causes the operation setting unit 11 to hold it.

  When the work light switch S8H is operated while the work light is turned off, the NC device 10 controls the non-processing related operation unit 52 so that the work light is turned on. When the work lamp switch S8H is operated while the work lamp is lit, the NC device 10 controls the non-working operation unit 52 to turn off the work lamp.

  When the emergency stop switch S9H is operated, the NC device 10 controls the machine main body 50 so as to emergency stop the operation in the machining related operation unit 51.

  As described above, in the first example shown in FIG. 4, the first operation switch for performing the operation related to the machining in the machine main body 50 is displayed corresponding to the low sensitivity region 31 </ b> L having relatively low sensitivity. It is displayed in the area.

  Further, in the first example shown in FIG. 4, the second operation switch for performing an operation not related to machining in the machine main body 50 or setting the operation in the machine main body 50 is relatively sensitive. Is displayed in a display area corresponding to the high sensitivity area 31H.

  In the low sensitivity region 31L, a reliable operation is required as compared with the high sensitivity region 31H. Therefore, the possibility that the first operation switch is inadvertently operated can be reduced, and the safety when operating the machine tool can be ensured.

  On the other hand, in the high sensitivity region 31H, a lighter operation can be performed as compared with the low sensitivity region 31L. Therefore, the second operation switch can be operated easily and with good operability.

  According to the first example, various operations can be executed by the touch panel 31 while achieving both operability and safety.

  As shown in FIG. 4, the emergency stop switch S9H is an operation switch for stopping the machine body 50 that is operating, and is required to respond immediately, so that a second operation that is not related to machining is performed. It is preferable to handle it as an operation switch. By displaying the emergency stop switch S9H in a display area corresponding to the high sensitivity area 31H, further safety can be ensured.

The third sensitivity of the high sensitivity region 31H in FIG. 5 is preferably higher than the second sensitivity of the high sensitivity region 31H in FIG.

  The NC device 10 can set the low sensitivity region 31L, the medium sensitivity region 31M, and the high sensitivity region 31H by setting the sensitivity when detecting contact with a finger or the like in three stages by software.

  When the touch panel 31 is a resistive film type touch panel, by setting the time until it is detected that the touch panel 31 is touched to three times, the low sensitivity region 31L, the medium sensitivity region 31M, and the high sensitivity region 31H Can be set.

  A method of setting three sensitivity areas on the touch panel 31 is arbitrary. The touch panel 31 may have a low sensitivity region 31L, a medium sensitivity region 31M, and a high sensitivity region 31H having different sensitivities by an arbitrary method. The positional relationship among the low sensitivity region 31L, the medium sensitivity region 31M, and the high sensitivity region 31H is not limited to FIG.
