Construction method of machining track corner transition arc, machining equipment and storage medium

Abstract

The invention discloses a construction method of a machining track corner transition arc, machining equipment and a storage medium. When the track corner type is LC or CL type, a track inflection point is set as O, and OBt is a vector pointing to the circle center of the arc track from the point O; the internally and externally tangent relation between the transition arc and the arc track is judged according to the included angle between the direction vector of the linear track and the OBt. When the track corner is in a CC type, two tracks are set as CD and CE respectively, ODt is a vector pointing to the circle center of the CD from a point O, OD is a direction vector of a tangent line of the CD at the point O, OEt is a vector pointing to the circle center of the CE from the point O, and OE is a direction vector of a tangent line of the CE at the point O; the internally and externally tangent relation between the transition arc and the CD and the CE is judged according to the angle DOE, the angle DOEt and the angle DtOEt. The method can quickly and accurately judge the internally and externally tangent relation between the constructed arc and the track, and construct the transition arc.

Description

technical field [0001] The present application relates to the field of processing technology, and in particular, to a construction method, processing equipment and storage medium for processing a corner transition arc of a processing track. Background technique [0002] During the machining process of CNC machining equipment (such as laser cutting equipment), the workpiece is generally processed according to the machining track pre-existing in the equipment. During the processing, if there is a sharp corner at the connection point of the two processing tracks, it will cause the processing head to vibrate strongly at the corner, which will affect the stability of the equipment. Although the vibration of the machining head can be mitigated or avoided by reducing the moving speed of the machining head at the corners, slowing down reduces the machining efficiency. Therefore, this problem is generally solved by adding a transition arc at the corner of the two trajectories, and t...

Problems solved by technology

In related technologies, the judging method for judging the inscribed relationship between the transitional arc and the arc track is not universal, and it cannot be guaranteed that the inserted transitional arc exists and is valid within the range allowed by the cutting accuracy, and it cannot be guaranteed that the constructed transitional arc is true. exist
