Abstract

The invention provides a five-axis tool path transfer fairing transition method, a medium and numerical control equipment of a five-axis machine tool, and the five-axis tool path transfer fairing transition method comprises the following steps: obtaining instruction information from a processing file of a workpiece, and analyzing the instruction information to obtain a five-axis track when the workpiece is processed; performing track preprocessing on at least two sections of tracks in the five-axis track; constructing a transfer transition curve between two adjacent sections of preprocessed tracks; and optimizing the tool machining path according to the speed constraint and the interpolation point of the transfer transition curve. The invention provides a transition method for transfer fairing, which can ensure the machining precision of a workpiece and ensure that the feeding speed / acceleration / jerk of a cutter is within a range allowed by a system.

Description

technical field [0001] The invention belongs to the technical field of five-axis machining, and relates to a transition method for transition from smooth to smooth, in particular to a transition method for smooth transition from five-axis tool paths, a medium and numerical control equipment for five-axis machine tools. Background technique [0002] In industries such as aerospace, automobile manufacturing, and shipbuilding, the processing of more complex mechanical parts is involved, and the application of free-form surfaces is becoming more and more extensive. Due to the introduction of the rotary axis, the five-axis CNC machine tool enables the tool to process the workpiece from multiple angles, greatly improving the flexibility of part processing, and is an effective way to achieve high-speed and high-precision machining of free-form surfaces. [0003] Currently, linear toolpaths are the most conventional NC code format for industrial applications. At the junction of two...
