Embodiment Construction

[0021] The system of the present invention first learns the working condition characteristics and accuracy of a certain part processed in large batches, wherein the working condition information includes cutting load and vibration. During the learning process, the learning module embedded in the numerical control system needs to obtain the corresponding processing instructions in real time. Collect the processing load and vibration corresponding to the instruction running, and at the same time obtain online or offline (manually input) the machining accuracy of the geometric position of the relevant parts, and the system automatically determines the processing instruction code corresponding to the geometric position of the part.

[0022] Then, analyze the error between the precision of the machined parts and the actual machining precision and the vibration characteristics, find the problematic machining position, determine the reasons that affect the precision and cause the vibra...

Abstract

The invention relates to a machining load control system based on instruction sequence optimization, which has a structure as follows: a parameter setting module is used for setting machining parameters, a machining constraint condition, a CAD (computer-aided design) data of machining parts and machining codes, providing a geometrical model of the parts and a machining instruction sequence code data, and generating a corresponding parameter file; a learning module is used for learning the cutting load, vibration and machining precision corresponding to the machining instruction sequence of the parts, generating a data file containing the parameter setting information and learning result of the learning module, and providing the cutting load, vibration and machining precision to an analysis module; the analysis module is used for confirming a to-be-optimized position and the machining instruction sequence code and graphically displaying the to-be-optimized position and the machining instruction sequence code; and an optimizing module is used for optimizing the machining instruction sequence, generating the machining instruction sequence code, performing statistic analysis, and generating an optimized machining instruction sequence code file. By using the machining load control system based on instruction sequence optimization, the high-precision machining is realized under the existing condition.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tool processing load control, in particular to a processing load control system embedded in a numerical control system based on command sequence analysis. Background technique [0002] CNC machine tool is an efficient automatic processing equipment. It strictly follows the processing program and automatically processes the workpiece to be processed. The program directly used for processing input from the outside of the CNC system is called the CNC processing program. It is a series of processing instructions. A collection of sequences, the NC machining program represents all the actions to be completed by the NC machine tool. [0003] Since the current NC machining program is only based on the geometric contour features of the machined parts when designing and writing, it is the geometric information expression of the machining trajectory, without considering the dynamic characte...
