Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the examples.

[0043] The invention provides a method for identifying the processing depth according to the value of the spindle acceleration sensor during the rectangular plane cutting process of the milling machine. According to the goals to be achieved in different stages of the method, the method is divided into two stages: the offline training stage and the online matching stage. The offline training stage mainly consists of five steps: training sample data collection, data preprocessing, feature extraction, fuzzy clustering, and knowledge base formation. The online matching stage consists of five steps: data collection, data preprocessing, feature extraction, and knowledge base comparison. consists of steps. Such as Figure 4 , Figure 5 shown.

[0044]Offline training stage: specify the maximum and minimum values ​​of the depth of the rectangular processing plane to be identi...

Abstract

The invention relates to a rectangular plane processing depth identification method for numerical control milling machine. The method comprises the following steps that in an offline training phase, adepth parameter of a rectangular processing plane which needs identification is set; in the processing scene, A processing tasks are designated to each scale in the measuring range, a sensor recordsan acceleration sequence in the processing process, and after that data preprocessing and feature extraction are carried out on the collected acceleration sequence of each processing task and a task vector is formed, all task vectors are clustered in a fuzzy way to form a knowledge base; and in an online matching phase, the rectangular planes are processed in different processing depths, in the processing scene, an accelerometer records the acceleration sequence in the processing process, and a characteristic vector obtained after data preprocessing and feature extraction is compared with theknowledge base to obtain the processing depth.

Description

technical field [0001] The invention relates to an automatic recognition method of machine tool processing engineering parameters, in particular to automatic recognition of processing depth in the processing process of a numerically controlled milling machine. Background technique [0002] With the rapid development of the new generation of information and communication technology and the continuous deep integration with advanced manufacturing technology, a new round of industrial transformation represented by intelligent manufacturing has emerged around the world. Germany proposed the "Industry 4.0" strategy, the United States proposed the "National Strategic Plan for Advanced Manufacturing in the United States", and the United Kingdom proposed the "British Industry 2050 Strategy". In order to meet the challenges of the new industrial revolution, China proposed "Made in China 2025" to vigorously promote the innovation-driven development of "smart manufacturing", and compreh...
