Abstract

The invention relates to an intersecting line digital cutting programming method for a round pipe with unequal wall thickness. The intersecting line digital cutting programming method is characterized by comprising the steps of a. lofting a pipe to be cut according to the model, programming the cutting program of the pipe at one end and determining the farthest cutting point; b. determining the groove angle at the farthest cutting point; c. taking the internal diameter as a benchmark side, and working out the length difference of the internal diameter and the external diameter after making the groove; d. programming the cutting program at the other cutting end and determining the farthest cutting point; e. determining the length difference of the internal diameter and the external diameter of the other end in the same style; f. calculating the cutting arc start point of the other end according to cutting start distance existing in the program. The intersecting line digital cutting programming method has the advantages that the aim of cutting the pipe with unequal thickness and the different pipe diameters can be realized after the cutting arc start point at the other end on the external diameter of the pipe is found.

Description

Do not wait wall thickness pipe intersecting lines number to cut program composition
Technical field
The present invention relates to a kind of wall thickness pipe intersecting lines number that do not wait and cut program composition.
Background technology
At present; known intersection cutting software can only satisfy the pipe cutting with the caliber stack pile; and for the pipe of different thick caliber and wall thickness; this type of software just lacks solution; and at ship domain; oceanographic engineering in construction steel structure and the petroleum pipe line production and construction, need be done the intersection cutting through the different thick pipe that regular meeting's discovery is stitched together.
Summary of the invention
The purpose of this invention is to provide a kind of wall thickness pipe intersecting lines number that do not wait and cut program composition.
The technical solution used in the present invention is:
Do not wait wall thickness pipe intersecting lines number to cut program composition, may further comprise the steps:
A. go out pipe to be cut according to modeling loft, work out the cutting process of an end pipe, establish cut point farthest;
B. determine the groove angle at cut point place farthest;
C. with internal diameter as reference side, in CAD, make the length difference of external diameter in holding successfully behind the groove;
D. work out the cutting process of an other cut end, establish cut point farthest;
E. determine the length difference on the interior external diameter of this end in the same way;
F. the cutting that carries according to program begins distance, calculates the cutting arcing point of the other end.
Advantage of the present invention is: the cutting that just can realize cutting different thick pipe and different thick caliber after finding out the cutting arcing point of an other end on the tube outer diameter.
Embodiment
The wall thickness pipe intersecting lines number that do not wait of the present invention is cut program composition, may further comprise the steps:
A. go out pipe to be cut according to modeling loft, work out the cutting process of an end pipe, establish cut point farthest;
B. determine the groove angle at cut point place farthest;
C. with internal diameter as reference side, in CAD, make the length difference of external diameter in holding successfully behind the groove;
D. work out the cutting process of an other cut end, establish cut point farthest;
E. determine the length difference on the interior external diameter of this end in the same way;
F. the cutting that carries according to program begins distance, calculates the cutting arcing point of the other end.
