Each was output independently. The details will be described below.

FIG. 6 is a configuration block diagram of a conventional numerical control information creation device.

As shown in the figure, in the conventional case, first, the key input data SA input from the keyboard 1 is input to the processed data input unit 2, and the processed data input unit 2 processes the processed data SB.
Is output to the processing condition calculation unit 3 and the processing locus calculation unit 5. The processing condition calculation unit 3 calculates the processing condition SC based on the input processing data SB and outputs it to the auxiliary function control information creation unit 4 and the axis movement control information creation unit 6. The auxiliary function control information creation unit 4 creates the auxiliary function control information SD based on the input processing conditions SC and outputs it to the numerical control information output unit 7.

On the other hand, the machining trajectory calculation unit 5 calculates the machining trajectory SE based on the machining data SB input from the machining data input unit 2 and outputs it to the axis movement control information creation unit 6. The axis movement control information creation unit 6 creates axis movement control information SF based on the input machining conditions SC and machining locus SE and outputs it to the numerical control information output unit 7.

Numerical control information output unit 7 receives the input auxiliary function control information SD
Also, the shaft movement control information SF is output as numerical control information SG to the outside in the form of the paper tape 8 or the magnetic disk 9.

(Problems to be Solved by the Invention) However, in the conventional numerical control information generation device as described above, regarding the numerical control information to be output,
Since auxiliary function control information and axis movement control information are output separately, there was a situation in which unnecessary time was used during non-cutting when actually used in a numerical controller. .

Hereinafter, the above-mentioned problems will be described with reference to the drawings in accordance with a specific example.

FIG. 7 is a diagram showing a non-cutting portion of the numerical control information output by the conventional numerical control information generating device.
FIG. 8 is a diagram showing a numerical control (NC) program format corresponding to the numerical control information in FIG. Figure 9 shows
It is a figure for demonstrating operation | movement at the time of using the numerical control information in FIG. 7 with a numerical controller. In FIG. 7, the axis movement control information is underlined.

The numerical control device executes the numerical control information line by line and operates based on it. For example, after the actual cutting is performed up to the sequence number N9, the row N10 is executed. 7th
In the figure, N10 to N15 are control information during non-cutting.

Therefore, first in N10, since the movement type is fast-forward and the positioning position is X = 110, the X-axis is moved to the position 110 by fast-forward by the NC program G00 X110 corresponding to this. Run N11 after N10 is complete. In N11, the spindle rotation is stopped and the cutting fluid is off, so the NC program M05 M09 corresponding to this stops the spindle and stops the cutting fluid. Run N12 after N11 is complete. In N12, the movement type is fast-forward and the positioning position is X = 300,
Since Z = 300, NC program equivalent to this is G00 X3
00 Use Z300 to move the X axis to the 300 position in rapid traverse and move the Z axis
Move to position 300. Run N13 after N12 is complete. In N13, the spindle speed is constant at 347 rotations and the gear is M4.
Position 1; spindle rotation is reverse; cutting fluid is input; turret is tool position 7; NC program G9 corresponding to this
7 S347 M41 M04 M08 T07 Designate a constant rotation speed of 347 rotations, set the gear to M41 position to rotate the spindle in the reverse direction, and insert cutting fluid to swivel the turret to the 7th tool position. Run N14 after N13 is complete. In N14, the movement type is fast-forward and the positioning position is X = 110, Z = 103
Therefore, the equivalent NC program G00 X100 Z10
By 3, the X-axis is moved to the position 110 and the Z-axis is moved to the position 103 by rapid feed. Run N15 after N14 is complete. N1
In 5, since the main rotation speed is the constant peripheral speed 120, the constant peripheral speed is designated by the NC program G96 G110 S120 corresponding to this, and the peripheral speed is set to 120. After N15 is completed, actual cutting is restarted.

As described above, in the conventional numerical control information creation device,
Since the created axis movement control information and auxiliary function control information are output separately, the axis movement during non-cutting (dashed line portion in FIG. 9) and auxiliary function control (9th embodiment) are performed even when the numerical control device is executed. They are done separately in time, since the black circles in the figure (which are done with the axis stopped) are not done at the same time and one does not work unless the other is done.

However, in most cases, there is no problem even if the axis movement during non-cutting and the control of the auxiliary function are performed at the same time. Therefore, there is a problem that the time saved by executing them at the same time is wasted. It was

The present invention has been made under the circumstances as described above, and an object of the present invention is to perform numerical control capable of creating numerical control information that reduces unnecessary operation time during non-cutting and shortens overall processing time. An information creating device may be provided.

(Means for Solving the Problem) The present invention relates to a numerical control information creation device that creates numerical control information based on input processing data, and the above-mentioned object of the present invention is to provide the input processing. Spindle stop based on data, turning of the turret,
Auxiliary control information separating means for separating auxiliary function control information concerning auxiliary functions such as turning on / off of cutting fluid into information concerning functions performed during actual cutting and information concerning functions performed during non-cutting, and based on the machining data. Axis movement control that separates the axis movement control information related to the axis movement functions such as the movement path, positioning position, and feed speed of the tool created by the information into the information about the functions performed during actual cutting and the information about the functions performed during non-cutting This is achieved by comprising an information separating means and a synthesizing means for synthesizing auxiliary function control information and axis movement control information regarding the function performed during the non-cutting.

(Operation) In the present invention, the auxiliary function control information regarding the auxiliary function created based on the machining data is separated into the information regarding the function performed during the actual cutting and the information regarding the function performed during the non-cutting, and In addition, similarly, the axis movement control information about the axis movement function is separated into the information about the function performed during actual cutting and the information about the function performed during non-cutting, and the auxiliary function control information about the function performed during non-cutting and By synthesizing axis movement control information, auxiliary function control information and axis movement control information related to functions performed during non-cutting can be performed so that axis movement control and auxiliary function control can be performed in parallel during non-cutting. Numerical control information on the same line can be created.

(Example) Hereinafter, the Example of this invention is described in detail based on drawing.

FIG. 1 is a block diagram showing the configuration of the numerical control information generating apparatus according to the present invention. The same components as those of the conventional device are designated by the same reference numerals and the description thereof will be omitted.

In the figure, the auxiliary function control information SD output from the auxiliary function control information creating unit 4 is input to the auxiliary function control information separating unit 10, and the auxiliary function control information separating unit 10 receives the input auxiliary function control information SD. Is separated into auxiliary function control information SI during actual cutting and auxiliary function control information SH during non-cutting, and auxiliary function control information SI during actual cutting is output to the numerical control information output unit 7 for auxiliary function control information SH during non-cutting. Is output to the control information synthesizer 12.

Further, the axis movement control information SF output from the axis movement control information creation unit 6 is input to the axis movement control information separation unit 11, and the axis movement control information separation unit 11 receives the input axis movement control information SF.
The axis movement control information SK during actual cutting and the axis movement control information during non-cutting
Separated into SJ, the actual cutting axis movement control information SK is outputted to the numerical control information output section 7, and the non-cutting axis movement control information SJ is outputted to the control information synthesizing section 12.

The control information synthesizing unit 12 having the non-cutting auxiliary function control information SH and the non-cutting axial movement control information SJ input together can perform the auxiliary function control and the axial movement control at the same time by non-cutting numerical control. The information SL is created and output to the numerical control information output unit 7.

FIG. 2 is a diagram showing a processing procedure of the control information combining unit.

In the control information synthesis unit 12, first, the auxiliary function control information separation unit 10
Further, all the non-cutting auxiliary function control information SH is input (step S1). Subsequently, one piece of non-cutting axis movement control information SJ is input from the axis movement control information separating unit 11 (step S2), and the non-cutting auxiliary function control information SH input in step S1.
It is determined whether or not there is information that can be output simultaneously (step S3). If it is determined that there is information that can be output simultaneously in step S3, the non-cutting auxiliary function control information SH and the non-cutting axis movement control information SJ that can be output simultaneously are combined and output (step S4), If it is determined that there is not, the axis movement control information SJ during non-cutting is independently output (step S5).

Next, it is determined whether or not the non-cutting axis movement control information SJ still remains (step S6), and if there is remaining, the process returns to step S2 and repeats the processing. On the other hand, when there is no remaining, it is judged whether or not there is any one of the non-cutting auxiliary function control information SH input in step S1 that requires independent output (step S7). The time auxiliary function control information SH is output (step S8), and the process returns to step S7. On the other hand, if not, the process ends.

Hereinafter, a specific example based on FIGS. 3 to 5 will be described.

In this example, after performing the actual cutting up to the sequence number N9, the operation is performed based on the control information during non-cutting from N10 to N12.

Therefore, first, in N10, since the movement type is fast-forward and the positioning position is X = 110, the X-axis is moved to the position 110 by fast-forward by the NC program G00 110 corresponding to this. After this N10 is completed, execute N11. With N11, the traverse type is fast-forward, and the positioning position is X = 300, Z = 3
00, Spindle rotation stopped, cutting fluid off, Spindle operation confirmed after axis movement, NC program equivalent to this is G00 X300 Z
It becomes 300 M05 M09 M63. If these numerical control information are simply on the same line, the numerical controller will move the axis after confirming that the spindle has stopped.Therefore, M63, which is a command to confirm the spindle operation after the axis movement, also has auxiliary function control information. Add as. As a result, the X-axis is moved to the position of 300 and the Z-axis is moved to the position of 300 by rapid feed, and the spindle is stopped in parallel to cut off the cutting fluid.

Run N12 after N11 is complete. With N12, the moving type is fast-forwarding, the positioning position is X = 110, Z = 103, and the turret is 7
Tool position, tool rotation speed is constant peripheral speed 120, gear position is M41, spindle rotation is reverse rotation, cutting fluid is input, and spindle operation and axis movement are performed in parallel, so spindle operation is confirmed after axis movement. Yes, the equivalent NC program is G00 X110 Z103 T0
7 G96 G110 S120 M41 M04 M08 M63 As a result, the X-axis is moved to the position of 110 and the Z-axis is set to 1 by rapid traverse.
Move to the position 03, and in parallel, turn the turret to the 7th tool position, specify the constant peripheral speed of the peripheral speed 120 for the tool, set the main shaft gear to the position of M41 and reverse the main shaft, Use cutting fluid. When N12 is completed, the next actual cutting starts.

According to the above-described embodiment, the numerical control information generation device outputs the axial movement control information and the auxiliary function control information, which are performed during non-cutting, of the numerical control information to the same line as shown in FIG. When this is executed by the numerical control device, the axis movement without cutting (broken line in FIG. 5) is performed in parallel with the peripheral control, so unnecessary waste of time can be eliminated. .
