Abstract

The invention discloses a process design method for milling precision consistency, and belongs to the technical field of milling cutters. Due to the fact that in the prior art, design indexes are incomplete, targets are unclear, accurate control over error distribution of the machined surface cannot be achieved, and the milling process design method is improved aiming at the problems. According tothe method, evaluation indexes of processing precision evaluation are increased, and precise control of processing error distribution is realized. The method comprises: designing a milling vibrationtest, extracting vibration test data, carrying out whole-process dynamic detection on milling vibration, and analyzing the milling vibration and the machining precision by using an improved grey correlation analysis algorithm; and analyzing the dynamic change of each parameter of the precision of the machined surface along with the cutting stroke through a grey correlation algorithm. According tothe process design method, the optimization design, the dynamic design and the collaborative design are comprehensively applied, the original process design method is optimized through the evaluationmethod for the precision consistency of the machined surface, and the machining precision and the consistency level of the machining precision are improved.

Description

technical field [0001] The invention relates to a method for designing consistent milling precision, in particular to a process design method for consistent milling precision, belonging to the technical field of milling cutters. Background technique [0002] The size and distribution characteristics of the milling surface accuracy directly affect the performance of the bonding surface on large structural parts. The existing milling process design methods aim at controlling the maximum value of the milling surface accuracy, without considering the consistency control of the milling surface accuracy , leading to the diversity and uncertainty of the machining accuracy distribution on the milling surface, which cannot meet the machining quality requirements of the joint surface on large structural parts. Therefore, on the basis of the existing milling process design method, the process design method of milling precision consistency can realize the effective control of the proces...
