[0053] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0054] When CNC drills cut sheet metal, large pieces of scrap material are generated. If these scrap materials are not promptly and effectively handled, they can not only affect the normal operation of the CNC drill but can even cause safety accidents. Traditional methods of waste disposal, such as pausing the machine and manually removing the scrap material, are not only inefficient but also pose safety risks.

[0055] In order to solve the problems in the prior art, the present invention proposes a method for shredding processing waste to achieve efficient and safe shredding of waste. The shredding of the processing waste is described below. Figure 1 As shown, including but not limited to the following steps:

[0056] Step 110: Obtain a processing waste pattern from the plate processing data, wherein the plate processing data is used to control a numerical control drill to perform cutting processing on the plate.

[0057] In step 110, obtaining the machining waste pattern from the plate processing data is a key step that can help the CNC drill perform more precise and efficient cutting of the plate. By combining the Green formula to calculate the clockwise or counterclockwise direction of the pattern, the position and shape of the waste portion can be more accurately determined, thereby better controlling the machining path and parameters of the CNC drill, reducing waste generation, and improving material utilization. Regarding the identification of machining waste patterns, it is understood that when the starting point of the groove given by the machining file is equal to the end point and the machining depth is greater than or equal to the plate thickness, the groove will eventually be cut off and fall off, and the fallen portion is then determined to be waste.

[0058] Step 120: Determine a processing direction of the processing waste graphic according to the processing trajectory of the processing waste graphic.

[0059] In step 120, the machining trajectory corresponding to the waste pattern is extracted to clearly determine the position and shape of the waste pattern. For a waste pattern, which is a continuous and closed segment of vertices, Green's formula is used to calculate whether the pattern is clockwise or counterclockwise. This is done by integrating the plane vector v = P(x, y)i + Q(x, y)j along the edge of the pattern, i.e., the loop of the plane vector v = P(x, y)i + Q(x, y)j along the boundary L of the pattern D = [a, b] x [c, d]. A positive integral indicates a counterclockwise vertex order, a negative one indicates a clockwise order, and a zero integral indicates an invalid pattern.

[0060] Step 130: Determine the tool offset direction according to the machining direction.

[0061] In step 130, because the tool has a radius, if cutting is performed according to the originally set processing path, errors will inevitably occur in the processed graphics. Therefore, it is necessary to consider the radius of the tool and offset the original processing path. The final processed size after the tool diameter is adjusted is equal to the size of the original graphics, and no part outside the graphics will be cut. Among them, the tool diameter comes from the machine tool magazine configuration, and is filled in by the operator when adding a tool to the tool magazine after measuring the actual tool radius. When the equipment uses the corresponding tool to process the waste material, it offsets the graphics by a corresponding distance according to the radius of the tool.

[0062] Step 140 : offset the machining trajectory of the machining waste pattern according to the tool offset direction to obtain a target machining pattern.

[0063] In step 140 , the machining trajectory of the machining waste pattern needs to be offset according to the determined tool offset direction. The offset is a translation offset along the trajectory direction, and the direction of the translation depends specifically on the integral result of the above Green's formula.

[0064] Step 150: chopping the processing waste according to the target processing pattern.

[0065] In step 150, the method for cutting the waste material is determined based on the shape and size of the target processing pattern. Cutting can be performed using a tool or other equipment for crushing. The waste material is cut according to the determined cutting method. Ensure cutting accuracy and efficiency to avoid additional damage to the panel. The waste material is then processed and can be recycled or otherwise disposed of to minimize environmental impact. The processing area is then cleaned to ensure no waste remains and maintain a tidy work environment.

[0066] The present invention provides a method for shredding processing waste. This method obtains a processing waste pattern from plate processing data; then, based on the processing trajectory of the processing waste pattern, determines the processing direction of the processing waste pattern; then, based on the processing direction, determines a tool offset direction; then, offsets the processing trajectory of the processing waste pattern according to the tool offset direction to obtain a target processing pattern; and shreds the processing waste according to the target processing pattern. This method enables automatic, efficient, and safe waste shredding, improves CNC drilling efficiency, reduces equipment downtime and manual intervention, and eliminates safety hazards.

[0067] As a further optional embodiment, the step of obtaining a processing waste pattern from the plate processing data specifically includes:

[0068] extracting processing trajectory data from the plate processing data;

[0069] If the groove starting point of the processing trajectory data is equal to the end point and the processing depth is greater than or equal to the plate thickness, the processing trajectory data is a processing waste graph.

[0070] In this embodiment, machining trajectory data is extracted from the plate processing data, including information such as the coordinates of each cutting point, cutting depth, and cutting speed. The extracted machining trajectory data is then evaluated. If the starting and ending positions of a cutting point are identical, and the cutting depth is greater than or equal to the plate thickness, the machining trajectory data is marked as a machining waste pattern. The machining trajectory data marked as a machining waste pattern is then saved for subsequent waste disposal and processing.

[0071] As a further optional embodiment, the step of determining the processing direction of the processing waste pattern according to the processing trajectory of the processing waste pattern specifically includes:

[0072] determining a boundary loop amount of the processing waste graphic according to a processing trajectory of the processing waste graphic;

[0073] determining a processing direction of the processing waste pattern according to the boundary loop amount;

[0074] The specific method of determining the boundary loop amount of the processing waste graphic according to the processing trajectory of the processing waste graphic is as follows:

[0075]

[0076] Where D is a closed graphic area, the function P(x,y) has a first-order continuous partial derivative on D, L is the positive boundary curve of D, represents the double integral over the region D. When it is greater than zero, it means that the path sequence direction of the current description graphic is counterclockwise, when it is less than zero, it is clockwise, and when it is equal to zero, it is an invalid graphic.

[0077] Specifically, it is necessary to define a path and perform integration along the boundary of the waste graphics. This path can be a closed curve that circles along the edge of the waste graphics. Then, according to Green's formula, the plane vector v=P(x,y)i+Q(x,y)j is integrated along the defined path. The specific formula is ∮v·ds, where ds represents the infinitesimal arc length along the path. Subsequently, the boundary order of the waste graphics is determined based on the calculated circulation results. If the circulation is a positive number, it means that the vertex order is counterclockwise; if it is a negative number, it means clockwise; if it is zero, it means that the graphics are invalid or incompletely closed.

[0078] As a further optional embodiment, the step of determining the tool offset direction according to the machining direction specifically includes:

[0079] When the machining direction is clockwise, the tool offset direction is to the right of the machining direction;

[0080] When the machining direction is counterclockwise, the tool offset direction is to the left of the machining direction.

[0081] Specifically, refer to Figure 2 , when the order of the given vertices of the scrap graph is described clockwise, then the inward deviation is right-biased; refer to Figure 3 , on the other hand, if it is described counterclockwise, then the inward deviation is the left deviation. It can be understood that the left deviation and right deviation here refer to the left and right along the forward direction of a given vertex.

[0082] As a further optional embodiment, the step of offsetting the machining trajectory of the machining waste pattern according to the tool offset direction to obtain the target machining pattern specifically includes:

[0083] Determining a tool radius according to a waste processing side length, wherein the waste processing side length is less than a maximum waste side length that can be processed;

[0084] According to the tool offset direction, the processing waste pattern is offset by the tool radius to obtain the target processing pattern.

[0085] In this embodiment, the tool radius must be determined based on the length of the waste material to be processed. Ensure that the waste material side length is less than the maximum waste material side length that can be processed, so that the tool can fully process the waste material pattern. For example, if the maximum allowable side length of the fragments is n, since the tool diameter itself will cut more, a gap of n + tool diameter can be used to ensure that the fragments are at most square pieces with a side length of n.

[0086] Then, according to the tool offset direction, the machining waste pattern is offset by a tool radius. The offset can be a translation along the trajectory direction or a curve offset, depending on the shape of the tool and the offset requirements. By offsetting the machining trajectory, the target machining pattern can be obtained. This pattern is the version of the machining waste pattern after the tool offset, which can be used for CNC drilling processing control. Specifically, the offset method can be referred to Figure 4 First, offset each segment of the graphic. After the offset, there may be disconnection or intersection. Take the previous segment after the offset to the next segment for judgment. If it is disconnected, insert an arc with a radius of the tool radius to connect it. If it intersects, take the intersection point as the point after the inner offset. Until all the offset segments are processed, the inner offset graphic is finally obtained. Figure 5 .

[0087] It is understandable that if the original data is directly processed along the outer contour of the given shape, the final processed shape will be larger due to the influence of the tool diameter. Therefore, it is necessary to perform an internal offset to reduce the original shape as a whole.

[0088] As a further optional embodiment, the step of shredding the processing waste according to the target processing pattern specifically includes:

[0089] Performing grid segmentation on the target processing graphics to obtain a tool cutting path;

[0090] According to the tool cutting route and the target processing pattern, the processing waste is chopped.

[0091] In this embodiment, reference Figure 6 , it is necessary to decide how to cut the waste into smaller pieces based on the given waste graph (i.e. continuous vertices) and the maximum fragments that the machine can handle. Since the final fragments need to fall into the gap of the machine and be sent out through the automatic conveyor belt, the maximum size of the fragments is required to be controlled within a limited range. For example, when the maximum side length allowed for the fragments is required to be n, since the tool diameter itself will cut more, a gap of n + tool diameter can be used to ensure that the size of the generated fragments is controlled to a maximum of square blocks with a side length of n.

[0092] As a further optional embodiment, the step of performing grid segmentation on the target processing pattern to obtain a tool cutting route specifically includes:

[0093] Performing grid segmentation on the target processing pattern to obtain processing grid lines;

[0094] The endpoints of the processing grid lines are sorted to obtain a tool cutting route.

[0095] In this embodiment, reference Figure 7 、 Figure 8 , the cutting results are processed from small to large, with odd points as the entry point and even points as the exit point. When the cutting line is collinear with the contour line segment, the two end points of the line segment are taken as the intersection points; when it is tangent to the arc, it is recorded as two intersection points. In this way, there must be an even number of intersection points in the end, thus ensuring that the processing segment from the odd point to the even point is within the graphics or on the contour line of the graphics, and will not exceed the graphics. After each cutting line is processed, select the connection point closest to the next segment (such as Figure 7 、 Figure 8 At the same time, the next section of the cutting line cannot be skipped, otherwise large pieces will fall off and the actual size limit of the fragments cannot be met.

[0096] It is understandable that the minimum and maximum dimensions Xmin / Xmax / Ymin / Ymax of the target processing figure obtained after calculating the internal offset need to be calculated. For any figure, it is composed of straight lines and arcs. The maximum and minimum of the straight line are the maximum and minimum of the starting point and the end point. Since the arc has a protruding part, the minimum and maximum values ​​are not necessarily the starting point and the end point. The extreme points of the arc appear at the point where the tangent derivative is zero or the point where it is not differentiable. Therefore, the minimum and maximum values ​​of the arc can be initially set as the starting point and the end point of the arc. At the same time, check whether the angle swept by the arc passes through 0 / 90 / 180 / 270 degrees. If it passes through the above specific angles, the minimum and maximum values ​​will need to be compared with the initial minimum and maximum values. If it is greater than the initial maximum or less than the initial minimum, it will be updated to the position value of the above angle. The target processing figure is grid-segmented to obtain the processing grid lines: from Ymin to Ymax, Xmin to Xmax, the target processing figure is segmented using a distance interval of n + tool diameter.
