Method and system for automatically generating numerical control machining code based on capacitor detection technologies

Abstract

The invention discloses a method and a system for automatically generating a numerical control machining code based on capacitor detection technologies. The method comprises the steps of detecting a workpiece by using a capacitance principle so as to acquire the actual dimension of the workpiece; comparing the acquired actual dimension with the standard dimension of a standard component and calculating the geometrical deviation of the workpiece which does not conform to dimension requirements; automatically generating the numerical control machining code of the workpieces which does not conform to the dimension requirements according to the calculated geometrical deviation, the processing work type, the processing procedure and the processing method; and carrying out conversion and output processing on the automatically generated numerical control machining code. The method disclosed by the invention combines the capacitor detection technologies with the numerical control technology, can realize damage-free online detection for injection molding products, and is high in detection efficiency and detection precision; and meanwhile, the method can realize full automation of the process from detection, flash or raw edge removing and secondary processing and amendment of the products, is high in efficiency and low in cost, and can be widely applied to the field of numerical control machining of the injection molding products.

Description

technical field [0001] The invention relates to the field of numerical control machining of injection molded products, in particular to a method and system for automatically generating numerical control machining codes based on capacitance detection technology. Background technique [0002] During the injection molding process, the product often has problems with flashes or burrs due to defects caused by injection molding control (such as excessive injection pressure) or poor mold sealing, and special workers are required to check the flashes or burrs The products are scraped and corrected. [0003] In addition, when affected by factors such as external disturbances, some defective products will appear in the injection molding system (such as the surface size and smoothness of the product do not meet the requirements). In actual production, injection molding companies generally select defective products through manual inspection by workers and deal with them accordingly. F...

Problems solved by technology

However, when the current CNC machining system for injection molded products is programmed before processing, it generally can only generate CNC codes from the drawn 3D digital model through computer-aided software.

The NC code automatically generated by the computer-aided manufacturing software is different from the code of the NC machining system in format, so it needs to be manually edited and corrected, and then transferred to the NC system for processing, which is not convenient and efficient enough

Moreover, the current NC machining system for injection molded products still has to rely on the results of manual inspection to generate NC machining codes for secondary correction of defective products, which cannot fully automate the process from inspection to NC machining code generation. lower
