Monitoring and diagnosing system of operation and process state of numerically controlled cylindrical grinding machine

Abstract

A monitoring and diagnosing system of operation and a process state of a numerically controlled cylindrical grinding machine comprises a monitoring device of the operation and the process state of a grinding machine and a diagnosing device of the operation and the process state of the grinding machine. The monitoring device of the operation and the process state of the grinding machine comprises a monitoring sensor, a data collecting platform and a computer, the monitoring sensor is connected with the data collecting platform which is connected with the computer, and the monitoring device of the operation and the process state of the grinding machine is connected with the diagnosing device of the operation and the process state of the grinding machine. The functions of the diagnosing device of the operation and the process state of the grinding machine are achieved on the basis of the computer, the monitoring and diagnosing system of the operation and the process state of the numerically controlled cylindrical grinding machine carries out diagnosis according to measuring and analysis of the key signals in a grinding machine processing process, improves the quick response ability of a machine tool manufacturing enterprise to user malfunctions, and achieves the diagnosing of machine on-line faults by integrating an intelligent diagnosing module with the numerically controlled system part of an existing precision machine tool.

Description

technical field [0001] The invention relates to the technical field of monitoring and diagnosis, in particular to a system for monitoring and diagnosing the operation and process status of a numerically controlled cylindrical grinding machine. Background technique [0002] The core technology of CNC machine tool intelligent equipment is online detection technology and intelligent monitoring and diagnosis technology, which has the ability to monitor the processing process and judge the process state. In 2006, Japan's MAZAK Corporation exhibited the world's first intelligent machine tool at the IMTS exhibition. However, judging from the current development of intelligent machine tools at home and abroad, there is still a long way to go to achieve a mature "adaptive control" machine tool level, and there is still a long way to go. Carrying out a lot of in-depth research work, especially in the automatic collection, storage, adjustment and control of machine tool processing para...
