[0046] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0047] Figure 1 A flowchart showing a method for arc machining according to an embodiment of the present application is shown. Exemplarily, the arc machining method includes the following steps:

[0048] S110, import the workpiece image and the graphic data of the workpiece, wherein the graphic data includes the layer machining speed of the workpiece.

[0049] Specifically, the cutter system is a numerical control machining technology. During the process of machining a workpiece, it is necessary to perform layer processing on the workpiece image and set different machining speeds for different layers to achieve the best machining effect and quality. The layer machining speed of the workpiece refers to the way of adopting different machining speeds for different parts of the workpiece model in the cutter system to achieve the best machining effect. Since the structural complexity, strength requirements, machining difficulty and other factors of different parts are different, different machining speeds need to be adopted for different parts to ensure the best balance between machining efficiency and quality.

[0050] S120, determine the target arc in the workpiece image.

[0051] Exemplarily, the arc machining method performs sampling analysis on the detection points on any curve according to the geometric characteristics of the arc, and compares several groups of sampling results to quickly eliminate the curves that do not conform to the geometric characteristics of the arc. The arc machining method also samples again to take the midpoint of the detection points to distinguish a regular polygon from an arc.

[0052] For example, in one embodiment, as Figure 2 shown, the arc machining method performs sampling analysis on all curves of the workpiece image to determine the target arc in the workpiece image, including the following steps:

[0053] S121, evenly divide each curve into multiple detection points.

[0054] S122, initially extract multiple groups of detection points as the first detection points according to different sampling ratios to determine the initial arc based on the first detection points.

[0055] In one embodiment, the arc machining method initially extracts multiple groups of detection points as the first detection points according to different sampling ratios to determine the initial arc, including: respectively determining the centroid of the curve according to the first detection points of each group; judging whether the first error of the distance from the first detection points of each group to the centroid of the curve conforms to the first error interval; initially determining the curve whose first errors all conform to the first error interval as the initial arc.

[0056] Specifically, the arc machining method takes the average value of the distances from the first detection points to the centroids calculated for each group as the true value, the first error is the absolute error of the distances from the first detection points of each group to the centroids calculated for each group, and the geometric characteristics of the arc include: the distances from the detection points on the arc to the center of the circle are equal; the center of the arc coincides with the centroid of the arc. First, assume that the selected curve is an arc, then any selected detection points should conform to the characteristics of the points on the above arc; in order to avoid that some local points are not very regular, after determining the position of the first sampling detection point, sample the detection points evenly according to a certain sampling ratio. For example, the sampling ratio can be 30%. If a curve has 100 detection points and now 3 points need to be sampled for inspection, according to the point quantity ratio, the detection points at the 0%, 33%, and 66% positions should be taken, that is, the 1st, 33rd, and 66th detection points. To prevent special points from being sampled in a single draw, several groups can be sampled, and also sample the points evenly according to a 30% sampling ratio. The second group: 10%, 43%, 76%; the third group, 20%, 53%, 86%. Calculate the centroid of the arc according to the first detection points of each group respectively, and then calculate the distance from each first detection point to the centroid of the arc. If the errors of the distances from the first detection points of each group to the centers of each group are within the first error interval, then it can be considered that the curve is an arc. Among them, the first error interval is set according to the actual application situation.

[0057] S123, extract the midpoints between the first detection points and their adjacent points again as the second detection points to determine the target arc based on the second detection points.

[0058] In one embodiment, the arc machining method further extracts the midpoint between the first detection point and its adjacent point as the second detection point to determine the target arc according to the second detection point, including: determining the centroid of the initial arc according to the second detection point of each group; judging whether the second error of the distance from the second detection point of each group to the centroid of the initial arc conforms to the second error range; and determining the curve with the second errors all conforming to the second error range as the target arc.

[0059] Specifically, the arc machining method takes the distance from each first detection point to the centroid calculated for each group as the true value, and the second error is the error between the distance from the second detection point of each group to the centroid calculated for each group and the true value. If the points on the curve have passed the preliminary sampling analysis, then it can be considered that the points on the curve are all on a common arc or the vertices of a regular polygon. The arc machining method still takes points in the original sampling manner, such as 0%, 33%, 66%, but does not directly take the coordinates of the original first detection points, but takes the midpoint between the selected first detection point and its adjacent point; for example, if the total number of points on the curve is 100, the selected points are the 1st, 33rd, and 66th points; then the adjacent points are the 2nd, 34th, and 67th points; the second detection points are regenerated, and the coordinates of the second detection point can be the average of the coordinates of the 1st and 2nd detection points, and so on. The arc machining method calculates the centroid of the second detection point and the distance from each second detection point to the centroid, and judges whether the error between this distance and the distance calculated according to each first detection point conforms to the second error range. If it conforms, it is judged that the curve is the target arc; otherwise, the curve is not an arc.

[0060] S130, determine whether to limit the machining speed of the target arc according to the diameter of the target arc and the comparison result between the machining speed of the target arc layer and the target speed limit.

[0061] In one embodiment, the arc machining method performs circle fitting on the target arc by least squares fitting to calculate the diameter of the target arc.

[0062] Specifically, the specific calculation steps for determining the diameter of the target arc by least squares fitting are as follows: First, collect the coordinates of multiple points on the target arc, that is, the known data points, and plot them on the plane rectangular coordinate system to form a series of discrete data. Then, based on the collected data points, determine the starting point and ending point of the target arc, as well as the radian. After that, establish the parametric equation of the target arc, and calculate the distance from each data point on the target arc to the center of the circle through the parametric equation. Let the formula of the target arc be (x - a)² + (y - b)² = r², where a and b are the coordinates of the center of the circle, and r is the radius of the target arc. Then, define the error function, and the goal is to minimize the error function, that is, to minimize the sum of the squares of the differences between the distances from all discrete data points on the fitted target arc to the circumference and the actual distances. Using the least squares method, optimize the error function into a quadratic form. Finally, solve the optimal solution of the error function, and find the parameters of the target arc when the error function reaches the minimum value through an optimization algorithm (such as the Levenberg-Marquardt algorithm), that is, the diameter and the coordinates of the center point of the target arc.

[0063] Exemplarily, the arc machining method determines whether to limit the machining speed of the target arc according to the diameter of the target arc and the machining speed of the layer of the target arc, and limits the machining speed of the target arc with different diameters according to the target speed limit specified in the speed limit table.

[0064] For example, in one embodiment, as Figure 3 shown, the arc machining method determines whether to limit the machining speed of the target arc according to the diameter of the target arc and the comparison result between the machining speed of the layer of the target arc and the target speed limit, including the following steps:

[0065] S131, look up the speed limit table to determine whether the diameter of the target arc is within the speed limit range of the speed limit table, where the speed limit table includes the target speed limits corresponding to arcs with different diameters.

[0066] S132, compare the machining speed of the layer with the target speed limit to determine whether the machining speed of the layer of the target arc is greater than the target speed limit.

[0067] S133, if the diameter of the target arc is within the speed limit range and the machining speed of the layer is greater than the target speed limit in the speed limit table, then limit the machining speed of the target arc.

[0068] S134, if the diameter of the target arc is within the speed limit range and the machining speed of the layer is less than or equal to the target speed limit in the speed limit table, then do not limit the machining speed of the target arc.

[0069] Specifically, the target speed limit is the maximum machining speed that arcs or circles with different diameters can withstand. The software tool of the cutting system includes a small circle speed limit list, such asFigure 4 As shown, test according to the actual machine type to obtain a list of arc diameters and the maximum tolerable speeds. The maximum value of the speed limit range is the diameter of the arc with the largest diameter in the speed limit table, and the minimum value of the speed limit range is the diameter of the arc with the smallest diameter in the speed limit table. If the diameter of the target arc is within the speed limit range and the speed of the target speed limit is less than the layer processing speed, it is necessary to limit the speed of the current target arc, and then compare the layer processing speed of the target arc with the target speed limit specified in the speed limit table.

[0070] In one embodiment, the arc machining method further includes: if the diameter of the target arc is less than the speed limit range, limit the machining speed of the target arc to the target speed limit corresponding to the arc with the smallest diameter; if the diameter of the target arc is greater than the speed limit range, do not limit the machining speed of the target arc.

[0071] Specifically, the arc machining method also determines whether the diameter of the target arc is within the range of the smallest and largest arc diameters specified in the speed limit table. If the diameter of the target arc exceeds the maximum limit diameter range, the machining speed of the target arc is not limited; if the diameter of the target arc is less than the smallest speed limit circle diameter, it is limited according to the target speed limit corresponding to the smallest speed limit circle diameter in the speed limit table. If the diameter of the target arc is within the speed limit range, but the speed limit value corresponding to the diameter of the target arc is not specified in the speed limit table, the corresponding speed limit value can be obtained by linear interpolation. For example, Figure 4 It is stipulated that the target machining speed of an arc with a diameter of 1.1 mm is 15 mm / s, the target machining speed of an arc with a diameter of 2.1 mm is 20 mm / s, and the target machining speed of an arc with a diameter of 3.1 mm is 25 mm / s. Then, according to the proportional relationship between the diameter of the arc and the target machining speed, the target machining speeds corresponding to arcs with diameters of 1.5 mm, 1.6 mm, 2.0 mm, etc. can be calculated.

[0072] S140, limit the machining speed of the target arc that needs to be speed-limited to the target speed limit.

[0073] In this embodiment, the machining order of the arc is related to the path planning. Whether speed limit is executed or not, the machining order is executed according to the rules of the path planning. The speed limit only acts on the arc to be machined currently. If speed limit is required, the machining speed of the arc is forced to be modified. If speed limit is not required, it is executed according to the machining speed set in the original layer of the curve. The purpose of speed limit is to affect the machining speed because the general machining speed set according to the layer exceeds the machining speed that the current arc can bear. The speed limit only affects the speed of running the arc and does not affect the idle running speed from the current curve to the next curve.

[0074] The present application also provides an electronic device, which can be a computer or a numerical control system, for automatically controlling a knife cutting system and can implement graphical programming and preprocessing functions.
