NUMERICAL CONTROL MACHINING PATH PLANNING METHOD, AND NUMERICAL CONTROL MACHINING SYSTEM AND METHOD

摘要

A numerical control machining path planning method, and a numerical control machining system and a numerical control machining method. The planning method comprises: acquiring data of a first track section AB and a second track section BC that are adjacent before planning, wherein the first track section AB and the second track section BC intersect to form a corner; and according to a position relationship between the two known track sections, calculating a circle centre distance L and circle centre coordinates of a transitional arc EF as well as coordinates of endpoints E and F by virtue of the radius of the transitional arc EF and the radius of at least one known track section, thereby planning the corner as numerical control machining path data of the transitional arc by combining the track section data of the transitional arc EF and the data of the two known track sections. By using the above-mentioned technical solution, arc transition is performed between adjacent machining sections, so that the machining efficiency is improved, the impact on a machine tool is also avoided, and the machining quality is improved.
