Embodiment Construction

[0044] The following embodiments can make those skilled in the art understand the present invention more comprehensively, but do not limit the present invention to the scope of the described embodiments.

[0045] The fitting method applied to the sponge cutting file of the present invention is specifically realized through the following steps:

[0046] S1 data preprocessing: read the data in the cutting file, convert the data type, convert the string type to floating point type, remove the spaces in the cutting file, rewrite the cutting file into a data list with fixed format characteristics, define after rewriting The list of data is the first list.

[0047] S2 closed figure split: There are several patterns to be cut on the same sponge. Based on the principle that a single sponge cutting pattern must be a closed figure, the starting point and the end point of the closed figure have the same coordinates, and there will be many more in the first list. Set the coordinates of t...

Abstract

The invention relates to a fitting method applied to a sponge cutting file, which comprises the following steps of: firstly, preprocessing the cutting file, applying a Helen's formula to obtain coordinates of each point when the area of a triangle is minimum, then giving an error range during straight line fitting, judging whether a multi-section line formed by connecting the points can be subjected to straight line fitting or not, and if a condition is met, judging whether the multi-section line is subjected to straight line fitting or not. The method comprises the following steps of: fitting each multi-section line meeting conditions, solving an error list by adopting an arc fitting straight line method, solving an error precision list, giving an error range during arc fitting, judging whether the arc fitting straight line can be carried out or not, fitting the fitted multi-section straight line into an arc if the conditions are met, and completing the overall fitting of the sponge cutting graph. The method has the advantages that the small line segments are firstly fitted into the long straight line, then the multiple straight lines are fitted into the arc, the length of a cut file is reduced as much as possible, the acceleration and deceleration processes of a numerical control cutting machine in the cutting process are reduced, and the speed and smoothness of the sponge cutting process are improved.

Description

technical field [0001] The invention relates to the field of sponge cutting, in particular to a fitting method applied to sponge cutting files. Background technique [0002] When using the sponge cutting machine to cut the sponge, firstly, according to the shape to be cut, use the graphics drawing software to draw the cutting graphics, generate the cutting file, and then import the cutting file into the sponge cutting machine CNC software for processing. One of the functions of the sponge cutting machine is to process the cutting files generated by the automatic typesetting method. Such cutting files are converted in a single way during the graphic scanning and typesetting, which will cause the cutting pattern in the cutting file to become composed of polylines after scanning, specifically: such as: figure 1 A cutting method shown, the straight line or arc in the cutting graph is composed of several small straight lines after being enlarged, and there are certain corners bet...
