specific Embodiment approach 1

[0018] Specific implementation mode one: combine figure 1 , figure 2 , image 3 , Figure 4 The present embodiment is described. The numerical control programming method for steam turbine blade machining provided in the present embodiment specifically includes the following steps:

[0019] Step 1, carry out secondary development to UG (Unigraphics NX) three-dimensional software, compile plug-in, utilize the RBS, RES, SLG file that the RCS programming of numerical control program RCS programming needs of automatic output of plug-in; Described RBS file is used for defining steam path data, as figure 1 shown; the RES file is used to define the characteristics of the root cap of the blade and the data of each surface, such as figure 2 As shown; the SLG file is used to define the blade groove characteristics, such as image 3 shown;

[0020] Step 2: Replace the output RBS, RES, SLG files with the corresponding files in the NC program RCS, replace the original files, and then...

specific Embodiment approach 2

[0023] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the described compiling plug-in, utilizes plug-in to realize the step of RBS, RES, SLG file required for automatic output numerical control program RCS programming specifically includes:

[0024] Step 11, extract the data parameters of the three-dimensional model; these data include the four sides of the root crown of the blade, the conical surface of the blade transfer, straight grooves, arc grooves, steam channels, and blanks.

[0025] Step 1 and 2, filter out the required data;

[0026] Step 13: According to the data file format of the software, perform data calculation and logical judgment, and output the obtained results to the corresponding RBS, RES, SLG files.

[0027] UGAPI+C language is used to compile the UG plug-in, and the program code part is as follows:

Abstract

The invention provides a numerical control programming method of processing steam turbine blades and belongs to the technical field of numerical control programming. The method comprises the followingsteps of: firstly, carrying out a secondary development on a three-dimensional software, compiling a plug-in, and realizing automatic output of RBS, RES and SLG files required by RCS programming of anumerical control program by using the plug-in; and then replacing the output RBS, RES and SLG files by the corresponding files in the numerical control program RCS. The numerical control programmingmethod of steam turbine blade processing solves the problems of low efficiency and easy error caused by complex numerical control program programming in the processing of the existing turbine blades.The invention is capable of being used for numerical control programming of steam turbine blade processing.

Description

technical field [0001] The invention relates to a numerical control programming method for steam turbine blade processing, and belongs to the technical field of numerical control programming. Background technique [0002] A steam turbine is a rotary prime mover that uses steam with a certain temperature and pressure to work. It is widely used in industries such as driving generators, blowers, water pumps, gas transmission, and ships. As the heart of the whole unit, the steam turbine blade is its main rotating part. The quality of the blade directly affects the energy conversion efficiency of the steam turbine. At the same time, with the rapid development of science and technology, the market competition is becoming increasingly fierce. However, the technical preparation cycle is getting shorter and shorter, which puts forward new requirements for blade programming. The domestic blade industry generally uses special software to compile CNC machining programs. The more popula...
