Abstract

In the first place, the characteristic frequency of a workpiece before machining and the one at after machining are input (Step S1). In the next place, a region between the characteristic vibration of a workpiece before machining and the one after machining is set in a Campbell diagram (Step S2). Furthermore, the vibration components of a machining tool during machining are input (Step S3). Subsequently, the vibration components of a machining tool during machining are set in the Campbell diagram (Step S4). Thereafter, with respect to the region between the characteristic vibration of a workpiece before machining and the one after machining, the Campbell diagram is used to determine the rotational speeds (operating condition) of the machining tool outside the ranges where the vibration components of the machining tool resonate (Step S5). In the last place, workpiece machining is executed on the basis of the rotational speeds (operating condition) of the machining tool (Step S6). For this reason, the machined surface roughness of the workpiece can be improved, and the machining cost can be reduced.

Description

technical field [0001] The present invention relates to a control method and control device for an operating machine, which prevents chattering during machining of workpieces in an operating machine that performs cutting and the like. Background technique [0002] For example, in cutting machining, chattering occurs when the vibration of the machining tool resonates with the natural vibration of the workpiece. When chattering occurs, the roughness of the machined surface of the workpiece is poor and the cutting edge of the machining tool is worn due to the vibration. [0003] As a countermeasure against chattering, there is a method described in Patent Document 1, for example. In this method, the vibration data of the workpiece is obtained in the current process, and the vibration data is used to predict whether chattering will occur in the next process with higher machining accuracy. Based on the predicted chattering results, modify the following Processing data of a work...
