Method for interpreting feeding position of mechanical arm from machining file of cutting machine

Abstract

The invention discloses a method for interpreting the feeding position of a mechanical arm from a machining file of a cutting machine. The method comprises the following steps that S1, a NC file is traversed line by line, and all movement instructions are extracted; S2, according to the movement instructions, a feature method is used for determining endpoint coordinates of all cutting line segments, wherein endpoints comprise starting points and ending points; S3, the endpoints are used to compose non-repeating rectangles through a vertex method; and S4, the center position of each rectangle is calculated according to the four vertices of the rectangle, and a feeding position result is output to the mechanical arm. In this way, the machining file can be embedded in a numerical control system of the cutting machine, and the intervention of external computer software is not needed; the specific position for completely machining a small plate can be directly calculated through the currently commonly-used NC file, and seamless upgrading is realized for a furniture factory without special modification of NC file contents; the position of the plate is calculated through the file used bya machine table in real time and sent to the mechanical arm, and the accuracy is high; and compared with the method for obtaining a coordinate file to the arm through the software, the matching degreeis higher, and more safety is achieved.

Description

technical field [0001] The invention belongs to the field of interpreting computer files, and relates to a control method of a mechanical arm, in particular to a method for interpreting the cutting position of the mechanical arm from the processing file of a cutting machine. Background technique [0002] Woodworking cutting machine is a kind of numerical control equipment specially used for cutting boards. The raw material plates used to manufacture wardrobes and other cabinets are cut by cutting machines to form rectangular plates of different sizes, and then processed by subsequent equipment to become assembly parts of the cabinet. The NC file of the processing file refers to the CNC processing program used by the woodworking cutting machine; since most of the cutting machines on the market do not have complicated processes for cutting plates, such NC files are all cut by G01. The G code composition. [0003] Blanking refers to the process of removing the small plates cu...

Problems solved by technology

This method requires re-communication and development with the software developer, which is costly and time-consuming. Multiple files are generated at the same time and imported multiple times, which may cause confusion and unexpected errors; if the files loaded by the cutting machine and the arm system do not match, there may even be collisions. machine risk
