Description

Technical Field

[0001] The present invention relates to the field of intelligent manufacturing, in particular to the field of dust-free cutting of industrial cutting software, and specifically refers to a method, device, processor and computer-readable storage medium thereof for realizing intelligent four-way air blowing operation of cutting based on a motion control system. Background Art

[0002] During the panel processing, furniture factories have increased their environmental protection requirements and require chip-free production during the processing. In addition, if the wood chips on the surface of the workbench of the cutting machine are not clean, it may lead to poor adsorption of the panels, affecting the processing effect. At present, cutting machine manufacturers usually use four-way air blowing. During the spindle cutting process, the opposite blowing is turned on to blow up the wood chips in the slit, making it easier to suck the wood chips away. However, due to the difference in cutting routes, only the opposite blowing of the cutting route may not be able to completely blow up the wood chips, resulting in poor dust collection effect. (For example: if there are intersecting or overlapping cutting routes, turning on the blowing in only a single direction will blow the wood chips into the same direction or intersecting cut grooves, resulting in the dust collection effect not meeting expectations). However, if the blowing in four directions is turned on at the same time during the cutting process, the machine tool air pressure will be reduced, which may easily cause the machine tool air pressure detection alarm to affect the normal operation of other air pressure sensitive mechanisms.

[0013] (2.4) Record the starting point direction of the current cutting segment and the result of the above calculation.

[0014] Preferably, the step (2.3) specifically includes the following steps:

[0015] If the cutting is vertical or horizontal in the XY coordinate system, only the air blowing port in the cutting direction needs to be opened; if the cutting is oblique, two air blowing ports in the oblique direction need to be opened; if the cutting is an intersecting line segment, the air blowing ports in the horizontal positive and negative, vertical positive and negative, or all directions need to be opened according to the horizontal, vertical, or oblique direction of the intersecting line segment.

[0018] (3.2) Find the corresponding entry in the record based on the starting direction of the cutting point, and then find the starting and ending points of the intersection and the coincident line segments in the record;

[0019] (3.3) According to the parameters, the advance amount of opening the additional air blow is determined, and during the cutting process, whether the position where the air blow port needs to be opened is reached to open the port in the corresponding air blow direction, and whether the position where the air blow port needs to be opened is exceeded to close the additional air blow port.

[0037] As a preferred embodiment of the present invention, the step (2.3) specifically includes the following steps:

[0038] If the cutting is vertical or horizontal in the XY coordinate system, only the air blowing port in the cutting direction needs to be opened; if the cutting is oblique, two air blowing ports in the oblique direction need to be opened; if the cutting is an intersecting line segment, the air blowing ports in the horizontal positive and negative, vertical positive and negative, or all directions need to be opened according to the horizontal, vertical, or oblique direction of the intersecting line segment.

[0039] As a preferred embodiment of the present invention, the step (3) specifically includes the following steps:

[0040] (3.1) Open the opposite blowing ports according to the direction of the current cutting line segment. If the current cutting is an oblique cutting, open the blowing ports in the two opposite directions of the cutting direction at the same time;

[0044] a processor configured to execute computer-executable instructions;

[0045] The memory stores one or more computer executable instructions. When the computer executable instructions are executed by the processor, the various steps of the method for realizing the intelligent four-way blowing operation of cutting material based on the motion control system are implemented.

[0046] The processor of the present invention is used to realize the intelligent four-way air blowing operation of material cutting based on the motion control system, wherein the processor is configured to execute computer-executable instructions. When the computer-executable instructions are executed by the processor, the various steps of the above-mentioned method for realizing the intelligent four-way air blowing operation of material cutting based on the motion control system are realized.

[0048] In a specific embodiment of the present invention, the woodworking machine tool achieves dust-free cutting during the cutting process of large panels through spindle dust suction and air blowing devices in the four directions of spindle movement. The spindle dust suction is not effective in sucking dust from the debris in the cutting groove, so air blowing devices in the four directions of the spindle are added. The air blowing in the cutting movement direction is turned on during the cutting process to blow up the debris that falls into the cutting groove, and then the spindle dust suction will suck away the blown debris to achieve a dust-free table. The cutting trajectories of large woodworking panels often overlap and intersect. At this time, according to the existing solution, the cut debris will be blown into the gaps between the opposite grooves and the cross-cutting grooves, resulting in poor dust suction effect.

[0049] While maintaining the original opening of the opposite-direction air blowing in the cutting direction, this solution will pre-analyze the processing path before processing to obtain all the cutting segments to be processed. By calculating whether the segments intersect, overlap, or are parallel, the relationship data of each cutting segment and the already cut segments is obtained based on the existence of parallelism and the parallel spacing being less than the given parameter value and the overlap of the projections of the two segments in the parallel direction. If the current cutting segment in this tool path and the previous cutting segment have an intersection or overlap or are parallel and the spacing is less than the given parameter value, according to the associated feature information, an additional air blowing port is opened during the actual cutting to ensure that the current cutting debris will be blown away even if it falls into the groove of other cutting lines, so that the dust collection effect reaches the "dust-free" level.

[0050] During the cutting process of large panels, woodworking machine tools achieve dust-free cutting through spindle dust suction and air blowing devices in the four directions of spindle movement. The spindle dust suction is not effective in collecting dust from the debris in the cutting grooves, so air blowing devices in the four directions of the spindle are added. During the cutting process, the air blowing in the cutting movement direction is turned on to blow up the debris that falls into the cutting grooves, and then the spindle dust suction will suck away the blown-up debris to achieve a dust-free table. The cutting trajectories of large woodworking panels often overlap and intersect. At this time, according to the existing solution, the cut debris will be blown into the gaps between the opposite grooves and the cross-cutting grooves, resulting in poor dust suction effect.

[0051] While maintaining the original opening of the opposite-direction air blowing in the cutting direction, this solution will pre-analyze the processing path before processing to obtain all the cutting segments to be processed. By calculating whether the segments intersect, overlap, or are parallel, the relationship data of each cutting segment and the already cut segments is obtained based on the existence of parallelism and the parallel spacing being less than the given parameter value and the overlap of the projections of the two segments in the parallel direction. If the current cutting segment in this tool path and the previous cutting segment have an intersection or overlap or are parallel and the spacing is less than the given parameter value, according to the associated feature information, an additional air blowing port is opened during the actual cutting to ensure that the current cutting debris will be blown away even if it falls into the groove of other cutting lines, so that the dust collection effect reaches the "dust-free" level.

[0052] The Phoenix software platform is used as the motion control system as the basis, and the trajectory control is used to perform the pre-analysis operation of the tool path file; during actual processing, the parser sends an instruction to obtain the current point, and it is judged whether the current point reaches the starting point of the additional air blowing port that needs to be opened obtained in the pre-analysis and whether the processing direction is the same. If the same, the corresponding air blowing is performed according to the additional air blowing port that needs to be opened obtained in the pre-analysis.
