Embodiment Construction

[0073] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0074] The present invention is aimed at micromachining (mesoscopic scale) which requires higher processing quality and compensation, and both the scale of the workpiece and the scale of the required features are relatively small. By building a micro-groove processing system, calibrate the cutting force and each cutting force coefficient and compare it with the measured micro-cutting force, and use the theoretical model of the micro-groove as a reference standard to calculate the total deformation value during the micro-grooving process in real time. The total deformation value obtained by real-time measurement and calculation is used to adjust the processing parameters and offset, so as to complete the online deformation prediction and compensation requirements of micro groove workpiece processing.

Abstract

The invention relates to the field of machining, in particular to a method for predicting and compensating a machining deformation error of a miniature trough. A device form predicting and compensating the machining deformation error of the miniature trough comprises a machine tool working table, a micro milling cutter, a miniature groove piece, a dynamometer and a support, and the dynamometer and the support are arranged on the machine tool working table in parallel. According to the method, a displacement sensor is utilized to online monitor machining deformation of the miniature groove piece in real time, a sensing working table is utilized to transmit the adjusting information so as to conduct real-time adjustment on the miniature groove piece, uncertain factors caused by manual adjusting and radial undercut caused by workpiece deformation are eliminated, and accordingly the machining accuracy and the workpiece quality are improved. An adjuster is independent of a machine tool control system, a tool path planed by an existing program cannot be affected, the programming time is saved greatly, and accordingly the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of machining, in particular to a method for predicting and compensating machining deformation errors. Background technique [0002] Micro-groove parts are widely used in various fields, such as aerospace, medical equipment, biomedicine, communication information and fuel cells and other micro-machines. The structure of micro-machines is complex and requires high precision in shape and position. Micro-slots are an important part of micro-machines, and it is of great significance to ensure their machining accuracy. The deformation caused by force, heat, stiffness change, flutter and eccentricity during processing is the main cause of machining errors in micro-groove machining. Usually, this part of the error is reduced by selecting reasonable processing parameters and using cutting fluid. However, this method requires too much experience, and the selection of parameters usually consumes a relatively large amount of tim...
