Abstract

The invention provides a three-dimensional impeller variable-axis plunge milling semi-finishing cutter location planning method. The method comprises the following steps of: planning a cutter location according to three-dimensional impeller variable-axis plunge milling cutter location planning characteristics and geometric characteristics of a three-dimensional impeller; judging, screening and extracting the position types of cutter location points; after classifying all the cutter location points, calculating to obtain a cutter feeding location and a cutter lifting location corresponding to each cutter feeding termination cutter location point; outputting a cutter location file; and writing an MATLAB program according to the output cutter location file. According to the three-dimensional impeller variable-axis plunge milling semi-finishing cutter location planning method, the machining efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of numerical control machining tool position planning, in particular to a tool position planning method for semi-finishing milling with variable axis of a ternary impeller. Background technique [0002] The centrifugal three-way impeller is the core component of the centrifugal compressor, which is widely used in many fields such as metallurgy, petrochemical industry, and coal chemical industry. Its processing efficiency has been widely concerned by scholars at home and abroad. 60% to 90% of the material of the ternary impeller is removed during processing. In order to improve production efficiency, enterprises often use the processing method of three-axis high-speed milling in different areas, but this The remaining machining allowance of this machining method is uneven, and when dividing the machining area, in order to ensure as much cutting material as possible, in the machining area of ​​each impeller fl...
