[0074] Take the go-Mill350 blade five-axis machining center program post-processing with TNC530 as the control system and dual-rotating table as an example, including:

[0075] (1). Read the tool location source file.

[0076] (2) Processing of comment sentences. Treat the comment statement as a statement with the symbol ";" and write it into the NC program file.

[0077] (3). Processing of tool change character segment. Extract the tool number and tool change character segment and write it into the NC program file.

[0078] (4). Spindle speed S and rotation direction character segment processing: extract the spindle speed S and rotation direction character segment and write it into the NC program file.

[0079] (5) Processing of machine tool motion statements:

[0080] ●Extract tool position coordinate values ​​X, Y, Z and tool axis vector coordinate values ​​I, J, K in the machine tool motion statement;

[0081] The APT code format is as follows, where each data represents X, Y, Z, I,...

Embodiment 2

[0121] Take the A156 blade five-axis machining center program post-processing with the control system E580 and the structure of a turntable + a swing head as an example, including:

[0122] (1). Read the tool location source file.

[0123] (2) Processing of comment sentences. Put the comment statement in the bracket "()" and write it into the NC program file.

[0124] (3). Processing of tool change character segment. The tool number and tool change character segment are extracted, processed as comment sentences, and written into the NC program file.

[0125] (4). Spindle speed S and rotation direction character segment processing. Extract the spindle speed S and rotation direction character segment and write it into the NC program file.

[0126] (5). Processing of the tool information character segment. Extract the tool tip fillet character segment ToolRadius, and write the tool tip fillet value into the Cr variable.

[0127] (6) Processing of machine tool motion statements.

Abstract

The invention discloses a blade five-axis machining programming processing method and device. The method comprises the following steps: obtaining a cutter location source file corresponding to a first blade five-axis machining device; and carrying out post-processing on the cutter location source file to generate a numerical control program for a second blade five-axis machining device, wherein the post-processing comprises converting cutter location coordinates and cutter-axis vector coordinates in a coordinate system where the cutter location source file locates into corresponding rectilinear coordinates and rotational coordinates in the coordinate system of the second blade five-axis machining device, and converting each machining data in the cutter location source file into numerical control codes capable of being recognized by the second blade five-axis machining device. The method simplifies the programming process where the same part is machined by blade five-axis machine tools in different structures, thereby saving software purchase cost and training and learning time of technicians, reducing programming workload, and improving blade numerical control processing and programming efficiency.

Description

Technical field [0001] The invention relates to the field of aeroengine blade processing, in particular, to a five-axis blade processing programming method and device. Background technique [0002] The compressor blade of an aero engine is one of the key components of the engine. The blade profile is generally completed by milling processing using a five-axis blade machining center. The preparation of the NC machining program of the blade profile adopts special programming software. Commonly used blade processing machine tool manufacturers have their own dedicated programming software, such as Ferrari (Ferrari) machine tool application Ts85 programming software, Liechti (Liechti) machine tool application Turbosoft programming software, and Starrag (Strrarag) machine tool application RCS programming software. If the same part is to be processed on five-axis blade machining machines of different manufacturers and structures, it is necessary to purchase, train and learn a variety o...
