Description

RCS-based method for acquiring cutter list

Technical Field

The invention relates to the field of numerical control machining of blades, in particular to a method for acquiring a cutter list based on RCS.

Background

The blade is a key part in mechanical equipment such as a steam turbine, a water turbine, an air turbine and the like. The mass of the blades directly affects the energy conversion efficiency of the turbine. The basic structure of the blade is roughly divided into four parts: blade root, blade profile, lacing wire boss and blade shroud. According to the characteristics of each part of the blade, the corresponding cutter is required to finish machining, and the technological requirements of the blade are met, so that the numerical control program for machining the blade consists of a multi-step program and a plurality of cutters.

The RCS software developed by the company StarragHeckert, swiss, is a five-axis numerical control machining programming software dedicated to blades, which is a numerical control machining programming tool composed of a plurality of module software packages, and the data models of the software are blades, holes, slots, and the like. Programming a numerical control program with the RCS generates a variety of files such as DAT, RCL, TEC, TOL, NC, etc., and the numerical control machine recognizes only NC program codes. The numerical control program for each step of the blade is composed of a main program and a plurality of sub programs, and the tool names used by the programs are contained in the respective NC files. The main data information file in the RCS only contains the program processing contents of english, the processing time, the tool name, and the tool length.

Before the blade is machined, an operator in a workshop needs a detailed cutter list table, wherein the table needs information such as a cutter name, a cutter length, a blade length, a taper and the like, so that the cutter is distributed and placed on a cutter library frame of a numerical control machine tool before a certain procedure of the blade is produced, and the debugging time is shortened; the tool manager also needs the machining time of a certain process to arrange a production plan. The existing tool list table is manually filled by workers, the processing time of a certain procedure is also manually calculated, and therefore the efficiency is low and errors are prone to occurring.
