The movement amount calculation unit 103a calculates the movement distance of the tool 31 based on the calculated number of pixels and the value of the scale (scale) set in the storage unit 2 of the numerical control device 100. The movement amount calculating unit 103a obtains the movement speed of the tool 31 from the speed of drawing of the portion of the machining program 1 displayed on the display unit 101 and the value of the scale set in the storage unit 2. At the same time, the movement amount calculating unit 103a performs forward control for executing the blocks described in the machining program 1 in the same order as the automatic operation or backward control for sequentially returning the blocks whose execution has been completed, in accordance with the direction of drawing.
The movement distance of the tool 31, the movement speed of the tool 31, the reverse control of the machining program 1, and the forward control of the machining program, which are calculated by the movement amount calculation unit 103a, are transmitted to the drive mechanism 26 as a drive command 100a via the communication unit 103 b. The drive mechanism 26 that has received the drive command 100a performs machining on the workpiece 300 by the tool 31. As described above, the numerical control device 100 has a function of generating the drive command 100a for machining the workpiece 300 in accordance with the machining program 1 and controlling the machining device 200.
Fig. 2 is an external view of the processing apparatus shown in fig. 1. The machining device 200 shown in fig. 2 is an example of a vertical type machine tool having orthogonal 3 axes, and the machining device 200 includes: a stand 21; a saddle 22 provided on the mount 21 and driven in the y-axis direction; a table 23 provided on the saddle 22; and a column 24 fixed to the mount 21 and extending above the mount 21. A ram 25 is attached to the column 24, and a workpiece 300 is set on the table 23.
The processing apparatus 200 shown in fig. 2 includes: an x-axis drive mechanism 26x which is an actuator for driving the table 23 attached to the saddle 22 in the x-axis direction; a y-axis drive mechanism 26y that is an actuator for driving the saddle 22 attached to the mount 21 in the y-axis direction; and a z-axis drive mechanism 26z which is an actuator for driving the ram 25 attached to the column 24 in the z-axis direction. The x-axis drive mechanism 26x, the y-axis drive mechanism 26y, and the z-axis drive mechanism 26z correspond to the drive mechanism 26 shown in fig. 1, respectively.
The x-axis drive mechanism 26x includes: an x-axis motor 27 x; a feed shaft 28x driven by an x-axis motor 27 x; and a rotation angle detector 29x that detects the rotation angle of the feed shaft 28 x. The y-axis drive mechanism 26y has: a y-axis motor 27 y; a feed shaft 28y driven by a y-axis motor 27 y; and a rotation angle detector 29y that detects the rotation angle of the feed shaft 28 y.

The ram 25 and the spindle 30 are driven by a z-axis drive mechanism 26z attached to the column 24, and the workpiece 300 is machined by a tool 31 attached to the tip of the spindle 30. As a result, the 2-degree-of-freedom motion in the xy plane of the workpiece 300 and the 1-degree-of-freedom motion in the z-axis direction of the tool 31 are combined, and the material of the surface of the workpiece 300, which is the portion where the tool 31 and the workpiece 300 interfere with each other, is removed in the 3-dimensional space of xyz, that is, in the 3 degrees of freedom. Thereby creating a 3-dimensional shape.
Next, the operation of the numerical control device 100 shown in fig. 1 will be described. After the currently executed machining block is temporarily stopped, a destination block, which is a machining block to which the user is going to go to, is designated by a touch operation performed by the user on a display portion of the machining program 1 on the display unit 101. Then, by drawing the display portion of the machining program 1 of the block temporarily stopped and the destination block on the display unit 101, the movement amount calculation unit 103a calculates the number of pixels drawn on the display portion of the machining program 1 on the display unit 101 based on the length of the drawing and the number of pixels per unit length. Then, the moving distance calculating unit 103a calculates the moving distance and moving speed of the tool 31 based on the calculated number of pixels and the value of the scale set in the storage unit 2 of the numerical control device 100.
The operation of the movement amount calculating unit 103a will be described in detail with reference to the following symbols.

Fig. 3 is a diagram for explaining an outline of an operation according to a comparative example corresponding to a numerical control device according to an embodiment of the present invention. Fig. 4 is a diagram for explaining an outline of an operation of the numerical control device according to the embodiment of the present invention.
As shown in fig. 3, the machining program 1 has a plurality of block numbers "N1", "N2", and "N3", and commands corresponding to the respective block numbers. The numerical control device 100A according to the comparative example includes: the mechanical dial 40 and the pulse signal generator 41 operate the dial 40 by a person, and thereby the pulse signal generator 41 generates a pulse signal corresponding to the amount of rotation of the dial 40. The numerical control device 100A generates a signal indicating the rotation amount corresponding to the number of pulses of the pulse signal and a signal corresponding to the direction in which the turntable 40 rotates as a drive command along the machining program 1, and thereby determines the movement amount and the movement direction of the tool 31 in the machining device 200 by the drive command.
As described above, in the numerical control device 100A according to the comparative example, by operating the dial 40 in the clockwise or counterclockwise direction, the plurality of blocks described in the machining program 1 can be executed in the same order as the automatic operation according to the machining program 1, and the plurality of blocks described in the machining program 1 can be executed in the reverse order to the above order. In fig. 3, the clockwise rotation of the dial 40 is referred to as "forward control", and the counterclockwise rotation of the dial 40 is referred to as "reverse control". The forward control means that the plurality of blocks described in the machining program 1 are executed in the same order as the automatic operation according to the machining program 1, and the reverse control means that the plurality of blocks described in the machining program 1 are executed in the reverse order of the order. As shown in the lower side of the drawing of fig. 3, in the case of the "forward control", the instructions corresponding to the respective blocks are executed in the order of block numbers "N1", "N2", and "N3", and in the case of the "reverse control", the instructions corresponding to the respective blocks are executed in the order of block numbers "N3", "N2", and "N1".
However, in the numerical control device 100A of the comparative example, the mechanical dial 40 is necessary, and the degree of freedom in the arrangement of the interface such as the display and the operation buttons, not shown, constituting the numerical control device 100A is restricted in order to install the dial 40. In addition, when the number of blocks described in the machining program 1 is several tens of thousands of rows, in the numerical control device 100A of the comparative example, it takes a lot of time to rotate the turntable 40 many times to trace back to a block located before several thousands of rows to several tens of thousands of rows, and a lot of time is taken for the feeding operation of the machining device 200.
As shown in fig. 4, the numerical control device 100 according to the embodiment of the present invention is configured such that the user 50 selects a destination block of the display unit 101, and by drawing a display portion of the machining program 1 of the display unit 101, the number of pixels of the display unit 101 per unit time is calculated based on the length of drawing and the speed of drawing, and the moving distance and the moving speed of the tool 31 operating in accordance with the machining program 1 are determined based on the value of the scale set in the storage unit 2 of the numerical control device 100. Then, the backward control or forward control of the machining program 1 is determined according to the direction of the stroke of the display unit 101. The calculated movement distance of the tool 31, the movement speed of the tool 31, the reverse control of the machining program 1, and the forward control of the machining program 1 are configured to be output to the machining device 200 as the drive command 100a, and therefore the turntable 40 shown in fig. 3 is not required.
Fig. 5 is a flowchart illustrating an operation of the numerical control device according to the embodiment of the present invention. In S11, the numerical control device 100 displays the machining program 1 on the display unit 101, and the machining program 1 is in an execution state. In S12, the user temporarily stops the execution of the machining program 1. In S13, the user specifies a destination block. In S14, the user selects whether or not to draw the display region of the machining program 1 from the block in S12 at which the execution of the machining program 1 is temporarily stopped to the destination block specified in S13.
When the user has scribed the display portion in S14 (S14: Yes), the movement distance of the tool 31 up to the middle of the block of the machining program 1 corresponding to the length of the scribe line of the display portion is calculated in S16. In S18, the backward control or forward control of the machining program 1 is determined according to the direction in which the display portion is drawn up and down. In S21, the moving speed of the tool 31 is calculated from the speed of drawing the display region.
In S14, if the user does not draw a stroke of the display region (S14: No), in S15, the moving distance of the tool 31 is determined to be up to the destination block selected by the user in S13.
In the case where the user selects the magnification of the feed speed (S17: Yes), in S20, the moving speed of the tool 31 is calculated from the feed speed instructed by the machining program 1 and the magnification selected in S17.
If the user does not select the magnification of the feed speed (S17: No), the feed speed instructed by the machining program 1 is selected as to the moving speed of the tool 31 in S19. Then, in S22, the numerical control device 100 automatically executes the machining program 1 according to the specified conditions.
Fig. 6 is a diagram showing a state in which a machining program display portion from a current block to a destination block of a display unit is drawn upward, and a plurality of blocks are executed by forward control. As shown in fig. 6, the user selects the destination block "N10" of the machining program 1 displayed on the display unit 101, and the machining program display portion from the current block to the destination block of the display unit 101 is drawn upward, and the drawing ends between "N3" and "N4". Then, the tool 31 moves the tool 31 from 0mm to 10mm halfway on the X axis in accordance with the instructions of the blocks "N3" and "N4" in accordance with the length of the drawing of the display portion of the machining program. The details are explained by the following examples.

[ formula 2 ]
When the length of the stroke of the display portion of the machining program 1 on the display unit 101 is 10mm, the speed of the stroke of the display portion of the machining program 1 on the display unit 101 is 600mm/min, the scale of the movement distance set in the storage unit 2 is 1/100, the scale of the movement speed set in the storage unit 2 is 1, and the number of pixels per unit length is 3.37, the movement distance from the currently executing block, i.e., "N3" to "N4", is 10mm, and therefore, the movement distance of the tool 31 is 3.37mm and the movement speed of the tool 31 is 600mm/min are obtained from the above expression (2). Therefore, the cutter 31 is moved from 0mm to 3.37mm along the X-axis at a moving distance of 3.37mm and a moving speed of 600 mm/min.
Fig. 7 is a diagram showing a state in which a machining program display portion from a current block to a destination block of a display unit is drawn downward, and a plurality of blocks are executed by reverse control. As shown in fig. 7, the user selects the destination block "N0" of the machining program 1 displayed on the display unit 101, and the machining program display portion from the current block to the destination block on the display unit 101 is drawn downward, and the drawing ends between "N1" and "N2". Then, the tool 31 moves the tool 31 from 0mm to a middle of 50mm on the Z axis in accordance with the instructions of the blocks "N1" and "N2" in accordance with the length of the drawing of the display portion of the machining program. The details are explained by the following examples.

The number of pixels drawn in the display portion of the machining program 1 of the display unit 101: and (3) Pt.
Number of pixels per unit length of the display portion 101: pul 3.37 pix/mm.
Currently, the moving distance from the executing block "N1" to "N2": z is 50 mm.
[ formula 3 ]
When the length of the stroke of the display portion of the machining program 1 on the display unit 101 is set to 5mm, the speed of the stroke of the display portion of the machining program 1 on the display unit 101 is set to 300mm/min, the scale of the movement distance set in the storage unit 2 is set to 1/100, the scale of the movement speed set in the storage unit 2 is set to 1, and the number of pixels per unit length is set to 3.37, the movement distance from the currently executing block, i.e., "N1" to "N2" is 50mm, and therefore, the movement distance of the tool 31 is determined to be 8.43mm and the movement speed of the tool 31 is determined to be 300mm/min according to the above expression (3). Therefore, the cutter 31 is moved from 0mm to 8.43mm along the Z axis with a moving distance of 8.43mm and a moving speed of 300 mm/min.

In the case where the magnification of the feed speed is not selected, the moving speed is determined by the feed speed instructed by the machining program 1, and the machining program 1 is executed in order from the block "N1" to the block "N4".

The processor 62 performs arithmetic and control by software using the received data, and the memory 61 stores the received data or data and software necessary for arithmetic and control by the processor 62. The coordinate movement amount described above is input to the input/output unit 63, and the input/output unit 63 outputs the drive command 100a to the machining device 200. The display unit 60 corresponds to the display unit 101 shown in fig. 1. In the case of realizing the display control unit 102 and the drive command output unit 103 shown in fig. 1, the display control unit 102 and the drive command output unit 103 are realized by storing programs for the display control unit 102 and the drive command output unit 103 in the memory 61 and executing the programs by the processor 62.
In the present embodiment, the touch panel display unit 101 is used, but any input device may be used as long as it can receive an operation by a user, and an input device other than the touch panel display may be used. Examples of the input device other than the touch panel type include a mouse, a touch panel, and a track pad. By using these general-purpose input devices, it is possible to perform forward control and backward control without using the mechanical jog dial 40 even in the numerical control apparatus 100 having the non-touch panel type display unit 101.

The calculated moving distance of the tool 31, moving speed of the tool 31, reverse control of the machining program 1, and forward control of the machining program are transmitted to the driving mechanism 26, and machining of the workpiece 300 is performed by the tool 31 of the driving mechanism 26. With this configuration, the numerical control device 100 does not need the mechanical dial 40 provided in the numerical control device 100A of the comparative example, and the degree of freedom in the arrangement of interfaces such as a display and operation buttons, not shown, is improved. Even when the number of blocks described in the machining program 1 is several tens of thousands of lines, the blocks can be easily traced back to blocks located several thousands of lines to several tens of thousands of lines by touch operation, and the time required for the feeding operation of the machining apparatus 200 can be shortened.
The configuration described in the above embodiment shows an example of the contents of the present invention, and may be combined with other known techniques, and a part of the configuration may be omitted or modified without departing from the scope of the present invention.
