Method of machining complicated surface efficiently

Abstract

The invention discloses a method of machining a complicated surface efficiently, which comprises the following steps: (1) collecting cutter parameters, machining parameters and part information before improvement; (2) building a part simulation model to simulate the actual machining state before improvement; (3) getting the cutting force, cutting temperature and spindle load of the machining state through simulation; (4) changing the cutter information of the simulation model, and adjusting the geometric parameters of the cutter; (5) re-simulating a new simulation model to get the cutting force, cutting temperature and spindle load after adjustment; (6) comparatively analyzing the indicators before and after adjustment; (7) with constant cutting load as a criterion, adjusting the cutting machining parameters to ensure that the machining indicators of the cutter after adjustment are the same with those in the original state, and getting the cutting parameter values after adjustment; (8) simulating an improved machining model, and optimizing the cutter path with cutting load balancing as a goal; and (9) performing trial cutting machining. By balancing the cutting load, the machining process is stable, the efficiency of complicated surface machining based on a single process is improved, and machining chatter is eliminated.

Traditional processing methods are mostly based on trial cutting processing parameters. Through staged optimization of processing parameters, it is expected to achieve the best balance between processing efficiency and quality, but the effect is not ideal, and processing is often accompanied by phenomena such as processing chatter and surface torsion. Occurs, affecting the processing quality of parts, and the rough and fine stage in the processing process lacks clear boundaries, the same situation exists in most of the processing tools, each stage is only slightly different in processing parameters, the tool wear is more serious, and the overall processing efficiency Due to the constraints of parts processing status and tool wear, it is difficult to achieve effective improvement
