Abstract

The invention relates to a control method, in particular to an intelligent control method for a plunge milling cutter. The intelligent control method aims to solve the problems that in the machining process of an existing plunge milling tool, a vibration-damping and cooling control method is complex in operation and poor in universality, pollution is caused to the environment, the temperature measurement is not accurate, the cooling process is single, and the temperature and the vibration are not considered together. The intelligent control method comprises the following steps that the plungemilling cutter is arranged; and an acceleration sensor, a first displacement sensor, a second displacement sensor, a third displacement sensor, a fourth displacement sensor and a fifth displacement sensor transmit detected acceleration signals and displacement signals to a vibration signal controller, the vibration signal controller sends an instruction to a current controller according to the acceleration signals and the displacement signals, and the current controller adjusts currents in a first electromagnet, a second electromagnet, a third electromagnet, a fourth electromagnet and a fifthelectromagnet. The intelligent control method belongs to the field of machining.

Description

technical field

[0001] The invention relates to a control method, in particular to an intelligent control method for a plunge milling cutter, which belongs to the field of mechanical processing. Background technique

[0002] As the mainstream milling method in mechanical processing, plunge milling has the advantages of high metal removal efficiency and high processing quality, and is widely used. However, when processing the root of the water bucket of a power generation turbine, it is necessary to use a slender shape of the tool holder. The increase of the length-to-diameter ratio will inevitably produce obvious flutter, and it is difficult to achieve high-precision machining. In addition, the amount of metal removal is not constant during the processing of the water bucket, which will inevitably lead to constant changes in the vibration frequency of the cutter bar. , so there is a need for an intelligent tool holder that can automatically adjust according to different cutt...
