Problems solved by technology

When skipping, the back-and-forth reciprocating skipping trajectory is used for processing. Although UG and other software have various trajectory optimization methods, they cannot meet the special requirements for sorting multi-ring wave group hole data. Therefore, it is necessary to invent a laser processing method. Data Acquisition and Optimization Method of Multiwave Group Holes

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0027]The data acquisition and optimization method for laser processing multi-wave group holes described in this embodiment, a small part of the part is intercepted, and hole B is taken as an example to illustrate. Five coordinate data are required for CNC machining of five coordinate equipment, that is, three point coordinates data and two rotation axis data, for the X, Y, Z coordinate data of the hole, that is, the X, Y, Z coordinate point of point B, the processing program can directly use the data in the ".txt" file, and the ".txt" The vector data, that is, the X vector data B1A1, the Y vector data B2A2, and the Z vector data B3A3, cannot be converted into the rotation axis data recognizable by the CNC equipment. Using the LASERDYNE-780 laser processing system, the C axis data is vector data in XY The angle between the plane projection and the X-axis...

Abstract

The invention relates to a data acquisition and optimization method for laser processing of multiwave group holes. The acquisition method comprises the steps of acquiring by the selection modes of all holes on a conducting surface of UG software and storing a file with the extension name of '.txt'. The optimization method comprises the following steps: (1), opening the stored file with the extension name of '.txt' by using WORD software; (2), performing WORD edition for the first time; (3), performing optimal sequencing; (4), performing optimal operation; and (5), arranging into a processing program file. The invention particularly provides the data acquisition and optimization method for laser processing of the multiwave group holes, which solves the problems of high-efficiency programming and high-efficiency processing of the multiwave group hole processing program, successfully finishes multi-ring wave heat screen micro group holes and high-efficiency laser processing, and has the advantages of high processing efficiency and low cost.

Description

technical field [0001] The invention relates to the optimization of laser processing multi-wave group holes, in particular to a data acquisition and optimization method for laser processing multi-wave group holes. Background technique [0002] The heat shield of the afterburner cylinder of the aero-engine is a complex stamping and forming part of a thin-walled plate, and the schematic diagram of a typical part is as follows figure 1 shown. Its shape is a multi-ring wavy conical segment, the radius of the large end is 509.25mm, the radius of the small end is 434.2mm, the length of the part is 1006.2mm, and the fan angle is 45°. There are more than 10,000 smiles with a diameter of only 1mm distributed on the surface of the part. The design of the gas model group holes requires that the normal direction of these holes is perpendicular to the part surface, so the space coordinate points and space angles of each hole on it are different. The five-coordinate laser equipment is us...
