[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The milling method provided in the embodiment of the present application can be applied in the application environment shown in FIG. 1. The terminal 102 communicates with the server 104 through the network. The data storage system can store the milling data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices.

[0052] In an exemplary embodiment, as shown in FIG2 , a milling method is provided, which is described by taking the method applied to the terminal 102 in FIG1 as an example, and includes the following steps 202 to 210. Among them:

[0053] Step 202, obtaining the shape of the workpiece to be processed, and determining two planes to be processed based on the shape.

[0054] The included angle α between the two planes to be processed satisfies 110°≤α≤180°.

[0055] In some embodiments, the shape of the workpiece to be processed is acquired, and two planes to be processed whose included angles satisfy a condition are determined on the workpiece to be processed according to the shape of the workpiece to be processed.

[0056] Step 204, determining plane processing lines on two planes to be processed respectively.

[0057] In some embodiments, plane processing lines are respectively determined on the two planes to be processed, and the plane processing lines in the two planes to be processed correspond to each other. In this embodiment of the present application, the number of plane processing lines on each plane to be processed is not limited.

[0058] Step 206: Determine a transition curve based on the plane processing line.

[0059] In some embodiments, the transition curve is determined according to the plane processing lines of the two planes to be processed, wherein the plane processing line on each plane to be processed includes a vertical line perpendicular to the intersection line of the two planes to be processed.

[0060] Step 208, clamping the workpiece to be processed on a three-axis machining center.

[0061] For example, a workpiece to be processed is clamped on a three-axis machining center, which is a CNC machine tool that can control the movement of three axes, X, Y, and Z.

[0062] Step 210, controlling the flat-bottom milling cutter to perform processing according to the processing path.

[0063] Among them, the processing path is the plane processing line on the plane to be processed of the current flat-bottom milling cutter in the two planes to be processed, the transition curve and the plane processing line on the remaining planes to be processed in the two planes to be processed; the diameter D of the flat-bottom milling cutter satisfies 0.01mm≤D≤1mm.

[0064] In some embodiments, the plane to be processed by the currently aligned flat-bottom milling cutter is used as a reference plane, and the flat-bottom milling cutter is controlled to perform processing according to the plane processing lines, transition curves and paths of the remaining plane processing lines on the plane to be processed of the currently aligned flat-bottom milling cutter in the two planes to be processed.

[0065] Among them, the flat-bottom milling cutter is a cutting tool with a flat bottom of the cutter head and a straight blade.

[0066] In the above-mentioned milling method, the shape of the workpiece to be processed is obtained, and two planes to be processed are determined based on the shape; plane processing lines are determined on the two planes to be processed respectively; based on the plane processing lines, a transition curve is determined; the workpiece to be processed is clamped in a three-axis machining center; the flat-bottom milling cutter is controlled to perform processing according to the processing path; the processing path is sequentially the plane processing line on the plane to be processed of the currently aligned flat-bottom milling cutter in the two planes to be processed, the transition curve and the plane processing line on the remaining planes to be processed in the two planes to be processed; the diameter D of the flat-bottom milling cutter satisfies 0.01mm≤D≤1mm. In this way, by processing on the plane to be processed that meets the requirements according to the pre-set processing path, the wear of the flat-bottom milling cutter is reduced and the processing quality of the plane to be processed is improved.

[0067] In an exemplary embodiment, there are multiple planar processing lines on the plane to be processed, and any two planar processing lines on the same plane to be processed are parallel to each other; and an angle β between any planar processing line on one plane to be processed and any planar processing line on another plane to be processed satisfies -5°≤β-α≤5°.

[0068] In actual implementation, there are multiple planar processing lines on each plane to be processed, any two planar processing lines on the same plane to be processed are parallel to each other, and the angle β between any planar processing line on one plane to be processed and any planar processing line on another plane to be processed satisfies -5°≤β-α≤5°.

[0069] In the above embodiment, by controlling the angle between the planar processing lines on the two planes to be processed within a certain range, it is ensured that the processing path is not too steep, so that the milling processing method in the present application is more effective.

[0070] In an exemplary embodiment, a transition curve is determined based on a plane processing line, including: selecting preset points on the intersection line of two planes to be processed according to a preset spacing; for each preset point, determining a perpendicular line to the preset point on the intersection line on the two planes to be processed; determining a point on each perpendicular line that is a preset distance from the preset point as a tangent point, and determining a transition curve that passes through the two tangent points at the same time.

[0071] In actual implementation, on the intersection line of two planes to be processed, preset points are selected according to preset spacing. For each preset point, perpendicular lines to the preset points on the intersection line are determined on the two planes to be processed. A point at a preset distance from the preset point is determined on each perpendicular line as a tangent point, and an arc passing through the two tangent points is determined as a transition curve.

[0072] Wherein, each plane processing line on the plane to be processed includes a vertical line on the corresponding plane to be processed.

[0073] In the above embodiment, the transition curve is designed by a preset method, which ensures that the squeezing effect of the chips is reduced while maintaining the consistency of the processed shape, helps the tool to remove chips, reduces tool wear, and weakens the impact of cutting on the processed surface.

[0074] In an exemplary embodiment, all transition curves are parallel to each other; each planar processing line on the plane to be processed includes a vertical line on the corresponding plane to be processed; and the preset distance M satisfies 0.01D≤M≤0.5D.

[0075] In actual implementation, the transition curves corresponding to each set of perpendicular lines passing through the preset points are parallel to each other, and each plane processing line on the plane to be processed includes the perpendicular line on the corresponding plane to be processed. At the same time, the preset distance M from the preset point to the tangent point needs to satisfy 0.01D≤M≤0.5D.

[0076] In the above embodiment, the curvature of the transition curve is limited by limiting the preset distance from the preset point to the tangent point, so that the processing effect of the flat-bottom milling cutter is better.

[0077] In an exemplary embodiment, the plane to be processed by the aligned flat-bottom milling cutter is perpendicular to the main axis of the flat-bottom milling cutter.

[0078] In some embodiments, when the workpiece to be processed is clamped on a three-axis machining center, the plane to be processed of the flat-bottom milling cutter needs to be aligned to be perpendicular to the main axis of the flat-bottom milling cutter.

[0079] In the above embodiment, when the workpiece to be processed is clamped in the three-axis machining center, one of the planes is perpendicular to the tool spindle of the three-axis machining center. Under this condition, the plane to be processed is perpendicular to the flat-bottomed milling cutter and can be converted into plane processing, and the surface quality of the workpiece to be processed is good.

[0080] In an exemplary embodiment, the distance between any two adjacent planar processing lines is equal; the distance L between any two adjacent planar processing lines and the diameter D of the flat-bottom milling cutter satisfy L≤0.1D.

[0081] In actual implementation, the distance between any two adjacent plane processing lines is equal, and the distance L and the diameter D of the flat-bottom milling cutter need to satisfy L≤0.1D.

[0082] In the above embodiment, when the distance between any two adjacent planar processing lines is equal and within a preset range, the single processing volume is small and the interval between two adjacent processing paths is small, the tool wear is small and the tool mark depth is small, and the surface quality is good.

[0083] To explain the milling processing method in the present application in detail, an embodiment is applied to FIG3 for illustration. By way of example, the present application is illustrated by the milling processing method in a specific processing scenario.

[0084] As shown in FIG3 , the workpiece to be processed is clamped on the fixture of the three-axis machining center, and the cutter axis of the flat-bottomed milling cutter is perpendicular to a processing plane of the workpiece to be processed, and the flat-bottomed milling cutter is controlled to process the workpiece to be processed according to the processing path.

[0085] First, the shape of the workpiece to be processed is obtained, and two planes to be processed are determined according to the shape of the workpiece to be processed. Plane processing lines are respectively determined on the two determined planes to be processed, and the plane processing lines in the two planes to be processed correspond to each other one by one.

[0086] On the intersection line of two planes to be processed, select several preset points according to 0.05D. For each preset point, determine the perpendicular line of the preset point on the intersection line on the two planes to be processed respectively. Determine a point on each perpendicular line that is 0.02D away from the preset point as the tangent point, and determine the arc that passes through the two tangent points at the same time as the transition curve.

[0087] Wherein, each plane processing line on the plane to be processed includes a vertical line on the corresponding plane to be processed.

[0088] The workpiece to be processed is clamped on the three-axis machining center, and the processing plane of the flat-bottom milling cutter is aligned perpendicular to the spindle of the flat-bottom milling cutter.

[0089] Taking the plane to be processed of the currently aligned flat-bottom milling cutter as the reference plane, according to the plane processing lines on the plane to be processed of the currently aligned flat-bottom milling cutter in the two planes to be processed, the transition curves and the paths of the plane processing lines on the remaining planes to be processed in the two planes to be processed, the flat-bottom milling cutter is controlled to perform processing by running the processing program in the terminal.

[0090] The present application uses a flat-bottomed milling cutter to process the plane to be processed. At the same time, the slope of the micro-bevel processed by the flat-bottomed milling cutter on the same plane to be processed is consistent at every moment, so that the tool marks on the plane to be processed are small and the surface quality is good.

[0091] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
