[0061] In the specific implementation process of this step, first, the special gauge caliper measurement, the standard column measurement, the gauge measurement method is used to measure the to-be-milled conical hole or directly based on the design drawing reading to obtain the first parameter information of the to-be-milled conical hole, such as the to-be-milled conical hole large end radius value, the to-be-milled conical hole small end radius value, and the conical hole angle value.

[0063] In the specific implementation process of this step, based on the to-be-milled conical hole large end radius value and the to-be-milled conical hole small end radius value of the to-be-milled conical hole, a target tool is matched for the to-be-milled conical hole, the tool radius size of the target tool is smaller than the to-be-milled conical hole small end radius value, and the tool length is greater than the end mill depth of the to-be-milled conical hole.

[0065] In the specific implementation process of this step, based on the first parameter information and the second parameter information, the target tool running per degree angle corresponding diameter reduction, the target tool milling rotation total degree number, and the target tool center point running starting point are calculated and obtained; based on the to-be-milled conical hole and the tool center point running starting point, a milling three-dimensional rectangular coordinate system is constructed; based on the diameter reduction, the target tool milling rotation total degree number, the tool center point running starting point, and the three-dimensional rectangular coordinate system, the to-be-milled conical hole is processed by spiral line milling to obtain a target conical hole meeting the surface processing quality.

[0066] The first parameter information of the to-be-milled conical hole includes at least a large-end radius value of the to-be-milled conical hole, a small-end radius value of the to-be-milled conical hole, and a conical hole angle value; the second parameter information of the target tool includes at least a radius parameter value of the target tool, a per-week diameter reduction of tool operation, and a milling initial angle value; and the to-be-milled conical hole is subjected to spiral line milling processing based on the first parameter information and the second parameter information, so that the target conical hole meeting the surface processing quality is obtained. The milling processing method can improve the surface quality of the milled conical hole, improve the processing efficiency, and obtain the target conical hole meeting the design requirements.

[0067] In another embodiment of the present application, another milling method is provided, as shown in the following. Figure 2

[0068] Step S201: obtaining first parameter information of a to-be-milled conical hole, the first parameter information including at least a large-end radius value of the to-be-milled conical hole, a small-end radius value of the to-be-milled conical hole, and a conical hole angle value;

[0069] In the specific implementation process of the present step, the to-be-milled conical hole is first obtained, and the first parameter information of the to-be-milled conical hole, such as the large-end radius value BB1 of the to-be-milled conical hole, the small-end radius value BB2 of the to-be-milled conical hole, and the conical hole angle value HH8, is obtained by measuring the to-be-milled conical hole using a special gauge caliper, measuring using a standard column, measuring using a gauge, or directly reading on a design drawing.

[0070] Step S202: matching a target tool for the to-be-milled conical hole based on the first parameter information of the to-be-milled conical hole, and obtaining second parameter information of the target tool, the second parameter information including at least a radius parameter value of the target tool, a per-week diameter reduction of tool operation, and a milling initial angle value;

[0071] In the specific implementation process of the present step, a target tool is matched for the to-be-milled conical hole based on the large-end radius value BB1 of the to-be-milled conical hole and the small-end radius value BB2 of the to-be-milled conical hole, the tool radius size of the target tool is smaller than the small-end radius value BB2 of the to-be-milled conical hole, the tool length is greater than the end mill depth of the to-be-milled conical hole, and an end mill is used as the target tool of the to-be-milled conical hole. In actual application, the target tool has specifications such as φ12 mm, φ16 mm, and φ18 mm end mills, which are selected according to actual needs.

[0072] ​Step S203: based on the first parameter information and the second parameter information, a calculation process is performed to obtain a diameter reduction amount corresponding to each degree of target tool operation, a total number of target tool milling rotations, and an operation starting point of a target tool center point;

[0073] In the implementation process, the diameter reduction amount HH1 corresponding to each degree of target tool operation is obtained based on the diameter reduction amount BB3 of each revolution of tool operation; the diameter reduction amount is shown in the following formula 1:

[0074] HH1=BB3 / 360 (1)

[0075] Based on the large end radius value BB1 of the to-be-milled conical hole, the small end radius value BB2 of the to-be-milled conical hole, and the diameter reduction amount BB3 of each revolution of tool operation, a calculation process is performed to obtain the total number of target tool milling rotations HH2; the total number of target tool milling rotations HH2 is shown in the following formula (2):

[0076] HH2= (BB1-BB2) / BB3x360 (2)

[0077] Based on the large end radius value BB1 of the to-be-milled conical hole and the radius parameter value WR of the target tool, a calculation process is performed to obtain the operation starting point corresponding to the target tool center point. The distance of the operation starting point corresponding to the target tool center point from the center point of the large end surface of the big vertebral column is shown in the following formula (3):

[0078] HH3=BB1-WR (3)

[0079] Step S204: based on the to-be-milled conical hole and the operation starting point of the tool center point, a milling three-dimensional rectangular coordinate system is constructed;

[0080] In the implementation process, the X-axis of the three-dimensional rectangular coordinate system is determined along the starting point of the large end surface of the to-be-milled conical hole and the operation starting point corresponding to the tool center point; the Y-axis of the three-dimensional rectangular coordinate system is determined along the starting point of the large end surface and perpendicular to the X-axis; the Z-axis of the three-dimensional rectangular coordinate system is determined based on the starting point and perpendicular to the large end surface of the to-be-milled conical hole, thereby obtaining the milling three-dimensional rectangular coordinate system. This lays a foundation for subsequent control of the target tool to rotate to a predetermined position according to a preset angle increase.

[0081] Step S205: based on the diameter reduction amount, the total number of target tool milling rotations, the operation starting point of the tool center point, and the three-dimensional rectangular coordinate system, a helical line milling process is performed on the to-be-milled conical hole, thereby obtaining a target conical hole that meets the preset surface processing quality requirements.

[0082] In the specific implementation process, based on the three-dimensional rectangular coordinate system, the initial coordinate value (HH3, 0, 0) corresponding to the running starting point of the target tool is determined; as shown in Figure 4 、 Figure 5 and Figure 6 , point A in the figure is the running starting point of the target tool, based on the milling initial angle value and the preset angle increase, the first cumulative angle value when the target tool rotates to the first position is determined; specifically, for example: the position of point B in the figure is the first position, and point C in the figure is the position of one rotation of the target tool. When the preset angle increase a is 1°, the milling initial angle value b is 0°, the first cumulative angle value HH4=a+b=1° after the target tool rotates the preset angle increase 1° is calculated and obtained; based on the initial coordinate value and the first cumulative angle value, the first coordinate value of the target tool rotating from the initial coordinate value position to the first position according to the preset angle increase is obtained; first: based on the initial coordinate value (HH3, 0, 0), the preset angle increase a, the milling initial angle value b, the first cumulative angle value HH4, and the diameter reduction amount HH1 corresponding to each degree angle of tool running, the X-axis coordinate value HH5 corresponding to the rotation of the target tool from the initial position to the first position is obtained; the X-axis coordinate value HH5 corresponding to the rotation of the target tool from the initial position to the first position is shown in the following formula (4):

[0083] HH5=(HH3-HH4×HH1)×cos(HH4)(4)In practical application, the preset angle increase a and the milling initial angle value b can be set according to actual needs, for example: the preset angle increase can be selected as 2°, 5°, 8°, etc., and specifically, a suitable angle is selected according to the actual surface quality requirement to be milled, and the milling initial angle value b can also be 45°, 30°, etc., and is set according to actual needs. Then: based on the initial coordinate value (HH3, 0, 0), the preset angle increase a, the milling initial angle value b, and the diameter reduction amount HH1 corresponding to each degree angle of tool running, the Y-axis coordinate value HH6 corresponding to the rotation of the target tool from the initial position to the first position is obtained; specifically, the Y-axis coordinate value HH6 corresponding to the rotation of the target tool from the initial position to the first position is shown in the following formula (5):

[0084] HH6=(HH3-HH4×HH1)×sin(HH4)(5)

[0085] Then: based on the tool running each week diameter reduction amount BB3, the taper hole angle value HH8 and the preset angle increase amount a, the calculation processing is carried out to obtain the Z axis coordinate value HH9 corresponding to the target tool rotating from the initial position to the first position, so as to obtain the first coordinate value when the target tool rotates to the first position. The Z axis coordinate value corresponding to the target tool rotating from the initial position to the first position is shown in the following formula (6):

[0086] HH9=BB3 / tan(HH8) / 360×HH4 (6)

[0087] Thus, the first coordinate value when the target tool rotates from the initial position to the first position is (HH5, HH6, HH9). The size relationship between the first cumulative angle value HH4 and the total number of degrees HH2 of the target tool milling rotation is judged to obtain a judgment result; in actual application, the size of the total number of degrees HH2 of the target tool milling rotation is determined according to the first parameter information of the to-be-milled taper hole and the radius information of the target tool, for example: when it is determined based on the first parameter information and the radius information of the target tool that the target tool needs to rotate 10 times to complete the milling process of the to-be-milled taper hole, the size of HH2 is 360°×10=3600°. Based on the judgment result, the target tool is controlled to mill the to-be-milled taper hole to obtain a milling result. Specifically, when the judgment result is that the first cumulative angle value is less than the total number of degrees of the target tool milling rotation, the target tool is controlled to carry out helical line milling processing on the to-be-milled taper hole, so that the target tool rotates to the first position corresponding to the first coordinate value; specifically, HH4=1°<3600°, the target tool is controlled to carry out helical line milling processing on the to-be-milled taper hole, so that the target tool rotates to the first position corresponding to the first coordinate value. Based on the first coordinate value (HH5, HH6, HH9), the second coordinate value when the target tool rotates from the first position to the second position according to the preset angle increase amount is determined; based on the first cumulative angle value and the preset angle increase amount, the second cumulative angle value when the target tool rotates to the second position is determined; the second cumulative angle value is obtained by adding the first cumulative angle value and the preset angle increase amount, for example, when the first cumulative angle value is 1° and the preset angle increase amount is 1°, the second cumulative angle value HH4'=2° is obtained. First: based on the initial coordinate value (HH3, 0, 0), the preset angle increase amount a, the milling initial angle value b, and the diameter reduction amount HH1 corresponding to each degree angle of the tool running and the second cumulative angle value, the X axis coordinate value HH5' corresponding to the target tool rotating from the first position to the second position is obtained; the X axis coordinate value HH5' corresponding to the target tool rotating from the first position to the second position is shown in the following formula (7):

[0088] HH5' = (HH3 - HH4' x HH1) x cos(HH4') (7)

[0089] Then: based on the initial coordinate value (HH3, 0, 0), the preset angle increase a, the milling initial angle value b, the second cumulative angle value and the diameter reduction amount HH1 corresponding to each degree angle of tool running, the calculation processing is carried out to obtain the Y axis coordinate value HH6' corresponding to the target tool rotating from the first position to the second position. Specifically, the Y axis coordinate value HH6' corresponding to the target tool rotating from the first position to the second position is shown in the following formula (8):

[0090] HH6' = (HH3 - HH4' x HH1) x sin(HH4') (8)

[0091] Then: based on the tool running per week diameter reduction amount BB3, the taper hole angle value HH8, the preset angle increase a and the first cumulative angle value, the calculation processing is carried out to obtain the Z axis coordinate value HH9' corresponding to the target tool rotating from the first position to the second position, so as to obtain the second coordinate value of the target tool rotating to the second position. The Z axis coordinate value corresponding to the target tool rotating from the first position to the second position is shown in the following formula (9):

[0092] HH9' = BB3 / tan(HH8) / 360 x HH4' (9)

[0093] Thus, the first coordinate value when the target tool rotates from the initial position to the first position is (HH5', HH6', HH9'). When the second cumulative angle value is less than the total number of milling rotations of the target tool, the target tool is controlled to perform helical line milling processing on the taper hole to be milled, so that the target tool rotates to the second position corresponding to the second coordinate value. For example: when the second cumulative angle value HH4' = 2° < HH2 = 3600°, the target tool is controlled to perform helical line milling processing on the taper hole to be milled, so that the target tool rotates to the second position corresponding to the second coordinate value. The helical line milling processing process is repeatedly executed until the target cumulative angle value when the target tool rotates to the target position is greater than or equal to the total number of milling rotations of the target tool, the milling processing process is ended, the target tool is controlled to rotate to the milling initial position, and the target taper hole is obtained. For example: when HH2 = 3600°, when the target cumulative angle value is greater than or equal to 3600°, the milling processing process is ended, the target tool is controlled to rotate to the milling initial position, and the target taper hole is obtained.

[0094] The application obtains first parameter information of a to-be-milled conical hole, the first parameter information at least including a large-end radius value of the to-be-milled conical hole, a small-end radius value of the to-be-milled conical hole, and a conical hole angle value; based on each of the first parameter information of the to-be-milled conical hole, a target tool is matched for the to-be-milled conical hole, second parameter information of the target tool is obtained, the second parameter information at least including a radius parameter value of the target tool, a diameter reduction per revolution of the tool in operation, and a milling initial angle value; based on the first parameter information and the second parameter information, a diameter reduction per degree angle corresponding to the target tool in operation, a total number of degrees of rotation of the target tool in milling, and a running starting point of a center point of the target tool are obtained; based on the to-be-milled conical hole and the running starting point of the tool center point, a milling three-dimensional rectangular coordinate system is constructed; based on the diameter reduction, the total number of degrees of rotation of the target tool in milling, the running starting point of the tool center point, and the three-dimensional rectangular coordinate system, the to-be-milled conical hole is processed by spiral line milling, and a target conical hole meeting a preset surface processing quality requirement is obtained. The milling method of the application can improve the milling surface quality, obtain a target conical hole meeting a design requirement, and improve the milling efficiency and save the cost.
