specific Embodiment approach 1

[0022] Specific embodiment 1: The UG4.0-based spherical fine Archimedes spiral processing method of this embodiment includes the following contents:

[0023] 1. Planning the trajectory of the spiral machining tool;

[0024] 2. Select and confirm the structure and parameters of the tool;

[0025] 3. Correct the trajectory of the spiral processing tool in step 1, and then perform fine Archimedes spiral processing on the spherical surface according to the corrected trajectory;

[0026] Fourth, the spherical Archimedes spiral line edge trimming obtained in step 3 completes the spherical fine Archimedes spiral line processing method based on UG4.0.

[0027] Effects of this implementation:

[0028] This embodiment adopts Mitterrand's five-axis machining center and uses UG4.0 three-dimensional software to construct a spherical Archimedes through the establishment of three-dimensional spheres, the establishment of the mathematical equations of Archimedes spirals, and the parameterization of sphe...

specific Embodiment approach 2

[0030] Specific embodiment two: This embodiment is different from the specific embodiment one in that the specific process of planning the trajectory of the spiral machining tool in the step one is:

[0031] (1) Establish a sphere model: Set the center of the sphere as the origin of the sphere coordinate system through the UG4.0 software, and perform Boolean operations on the inner hole and end face of the sphere according to the requirements of the drawing to initially complete the establishment of the sphere entity;

[0032] (2) Establishment of spiral line:

[0033] Set the sine curve equation in UG4.0 software:

[0034] theta=t*360

[0035] xt=t

[0036] yt=sin(theta)

[0037] zt=0; where t represents the variable, xt represents the position of the curve on the X axis, yt represents the position of the curve on the Y axis, and zt represents the position of the curve on the Z axis;

[0038] (3) Establish the mathematical equation of Archimedes spiral: Archimedes spiral, when point P mov...

specific Embodiment approach 3

[0068] Specific embodiment three: This embodiment is different from specific embodiment one or two in that the selection and determination of the structure and parameters of the tool in the second step are specifically as follows:

[0069] The tool adopts imported cemented carbide rod material, the tool angle is 55°, the tool nose radius is ≤SR0.05, and a single cutting edge passing through the center is processed at the tool nose. The tool angle is related to the cutting speed of the machine tool. When the machine speed reaches 20,000 rpm / Min, the tool can choose a 30° angle, when the number of revolutions is less than 10000 revolutions / min, the angle of the tool cannot be less than 50°. Other steps and parameters are the same as those in the first or second embodiment.

Abstract

The invention relates to a spherical fine Archimedes spiral line machining method, in particular to the spherical fine Archimedes spiral line machining method based on UG4.0. The method aims to solve the problem that a conventional method can not meet the requirement for machining spherical fine Archimedes spiral lines based on the UG4.0. The spherical fine Archimedes spiral line machining method based on the UG4.0 comprises the steps of compiling a numerical control machining program, selecting and determining structures and parameters of cutters, machining the spherical fine Archimedes spiral lines, and carrying out edge rounding on the line scribing edges of the Archimedes spiral lines, so that the spherical fine Archimedes spiral line machining method based on the UG4.0 is completed. The spherical fine Archimedes spiral line machining method based on the UG4.0 belongs to the technical field of complex space curve numerical control machining.

Description

Technical field [0001] The invention relates to a spherical fine Archimedes spiral processing method, and belongs to the technical field of numerical control processing of complex spatial curves. Background technique [0002] In order to improve the service life of the ball bearing of the key parts of the oil-air suspension device, the design requires that the processing depth of the outer ball surface of the ball bearing is not more than 0.05mm, and the edge should be rounded with Archimedes sine spiral marking (such as figure 2 As shown), it is used to store lubricating oil, so that the parts are fully lubricated during work and improve the service life of the parts. [0003] Because the Archimedes spiral is a fine three-dimensional curve, it cannot be processed by conventional methods, and it is difficult to investigate many large domestic enterprises and research institutes. At present, there is no archimedes spiral engraving method that can be used for reference in China. The...
