Embodiment 1
[0068] The method for performing zoom laser precision machining of deep grooves using the above-mentioned device specifically includes the following steps:
[0069] (1) The workpiece is clamped on the zoom laser precision machining deep groove and deep hole device, and 6 focusing lenses are evenly arranged and installed on the focusing lens seat, so that it meets the following conditions:
[0070] 1) The laser beam is incident on the central axis of a focusing lens on the focusing lens seat, vertically incident along the Z direction and focused on the surface of the workpiece;
[0071] 2) The workpiece can be driven by the worktable to do translational movement in the X-Y direction, that is, the focused spot of the laser beam moves relatively on the surface of the workpiece;
[0072] 3) XYZ forms a Cartesian coordinate system;
[0073] 4) The diameter of the focus lens seat is 180mm. The diameter of the six focus lenses installed on it is 25mm, and the focal lengths are 120.0...
Embodiment 2
[0079] The method for performing zoom laser precision machining of deep holes using the above-mentioned device specifically includes the following steps:
[0080] (1) Clamp the workpiece and 8 focusing lenses on the zoom laser precision machining deep groove and deep hole device, so that it meets the following conditions:
[0081] 1) The laser beam is incident on the central axis of a focusing lens on the focusing lens seat, vertically incident along the Z direction and focused on the surface of the workpiece;
[0082] 2) The workpiece can be driven by the worktable to do translational movement in the X-Y direction, that is, the focused spot of the laser beam moves relatively on the surface of the workpiece;
[0083] 3) XYZ forms a Cartesian coordinate system;
[0084] 4) The diameter of the focusing lens seat is 250mm, and the diameters of the 8 focusing lenses installed on it are all 30mm, and the focal lengths are 100.0mm, 120.2mm, 120.4mm, 120.6mm, 120.8mm, 121.0mm, 121.2...
