Description

Technical Field

[0001] The present invention relates to the technical field of aero-engine technology, and in particular to a control method for machining a blade disk using adaptive software. Background Art

[0002] Adaptive machining software is now being used more and more widely in CNC machining. Adaptive software has two control modes: roughing to improve efficiency and finishing to ensure machining quality. Control is easy for conventional machining methods because roughing and finishing can be programmed separately. However, this is difficult for blade discs, which combine roughing and finishing for an integrated process. While roughing control can be added within the roughing program segment and finishing control within the finishing program segment, the blade disc program size approaches 0.8GB, and the program mixes hundreds of layers of mixed roughing and finishing. Manually adding control methods for each layer is a significant workload and can also lead to errors. If part quality is ensured during roughing and program efficiency is maintained during finishing, this will have a significant negative impact on the part. Summary of the Invention

[0003] The purpose of the present invention is to enable the hybrid milling program to automatically determine which adaptive control method should be used by formulating certain logical relationships, and to reduce the workload of process personnel.

[0004] This invention provides an adaptive software control method for machining blisks. Analysis reveals that blisk hybrid milling uses different cutting parameters during the roughing and finishing stages, with spindle speed variations being most pronounced. Spindle speeds below 3000 rpm are considered roughing, while those above 6000 rpm are considered finishing. Therefore, the spindle speed is used to determine the machining stage and invoke the corresponding adaptive control method.

[0006] Step 1: Prepare adaptive machining program;

[0007] 1.1 Design program architecture

[0008] 1.1.1 Set the program parameters, which are program parameters that control whether the program is in the control stage or the learning stage. For example: DEF INT XUEXI = 0 / 1 (0, for control; 1, for learning)

[0009] 1.1.2 Design program logic:

[0010]

[0011]

[0012] Step 2: Define the M instruction;

[0015] 2.3. Restart the CNC system and activate M104

[0016] Step 3: How to use M104;

[0017] 3.1. Change the program template, put the M104 command into the tool change and give the spindle rotation command.

[0018] 3.2. Re-output the blade disk hybrid milling program

[0019] 3.3、Adaptive software learning, enter the ZISHIYING program, and modify the parameter DEF INT XUEXI=0. Change it to XUEXI=1

[0020] 3.4. After learning, perform adaptive processing control, enter the ZISHIYING program, and modify the parameter DEF INT XUEXI=1. Change it to XUEXI=0

[0022] Advantages of the present invention:

[0023] The control method for machining a blade disk using adaptive software according to the present invention effectively applies the adaptive machining software to the machining of the blade disk and can reduce the workload of the process personnel.
