[0042] Embodiment 1

[0043] Figure 1 It is a flowchart of a method for analyzing the detection error of a small conical taper shown according to an exemplary embodiment. This method is used in a terminal and includes the following steps:

[0044] Step S101, when receiving an error analysis request, respectively obtain the small conical related data, the offset error of the origin of the measurement coordinate system along the Y-axis direction from the workpiece axis, and the angle offset error angle between the measurement coordinate system and the workpiece plane coordinate system in the error analysis request.

[0045] Among them, as Figures 2-3 shown, the relevant data of the small cone include: the minor diameter D1 of the frustum of the small cone, the major diameter D2 of the frustum of the small cone, the angle θ1 of the frustum of the small cone, and the height H of the frustum of the small cone. The detection error value of the taper of the cone includes: the offset error L of the origin of the measurement coordinate system along the Y-axis direction from the axis of the workpiece and the angle offset error θ3 between the measurement coordinate system and the workpiece plane coordinate system, which are respectively measured by a Taylor Hobson high-precision roughness profiler.

[0046] Step S102: Obtain the detection compensation value of the taper of the small cone based on the relevant data of the small cone and the detection error value of the taper of the cone.

[0047] Among them, the detection compensation value of the taper of the small cone includes: the cone line angle of the frustum after the offset of the origin of the measurement coordinate system along the Y-axis direction from the axis of the workpiece and the cone line angle of the frustum after the angle offset between the measurement coordinate system and the workpiece plane coordinate system.

[0048] When the detection error value of the taper of the cone is the offset error of the origin of the measurement coordinate system along the Y-axis direction from the axis of the workpiece, the relevant data of the small cone and the offset error of the origin of the measurement coordinate system along the Y-axis direction from the axis of the workpiece are used to obtain the cone line angle of the frustum after the offset of the origin of the measurement coordinate system along the Y-axis direction from the axis of the workpiece through formula (1):

[0049]

[0050] Where: D1 is the minor diameter of the frustum of the small cone, D2 is the major diameter of the frustum of the small cone, θ1 is the angle of the frustum of the small cone, H is the height of the frustum of the small cone, and θ2 is the cone line angle of the frustum after the offset of the origin of the measurement coordinate system along the Y-axis direction from the axis of the workpiece;

[0051] When the detection error value of the taper of the cone is the angle offset error between the measurement coordinate system and the workpiece plane coordinate system, the relevant data of the small cone and the angle offset error between the measurement coordinate system and the workpiece plane coordinate system are used to obtain the cone line angle of the frustum after the angle offset between the measurement coordinate system and the workpiece plane coordinate system through formula (2):

[0052]

[0053] Where, θ3 is the angle offset error between the measurement coordinate system and the workpiece plane coordinate system, and θ4 is the cone line angle of the frustum after the angle offset between the measurement coordinate system and the workpiece plane coordinate system.

[0054] When the taper detection error values of the small cone are the angles of the frustum cone line after the origin of the measurement coordinate system is offset along the Y-axis direction from the axis of the workpiece and the angles of the frustum cone line after the angle offset between the measurement coordinate system and the workpiece plane coordinate system, first obtain the angle θ4 of the frustum cone line after the angle offset between the measurement coordinate system and the workpiece plane coordinate system through formula (2). Substitute the angle θ4 of the frustum cone line after the angle offset between the measurement coordinate system and the workpiece plane coordinate system into formula (1) to replace θ1 with the small cone frustum angle. The angle of the frustum cone line after the origin of the measurement coordinate system is offset along the Y-axis direction from the axis of the workpiece is the small cone taper detection compensation value common to both cases.
