Intelligent management method for numerical control machine tool

Abstract

The invention discloses an intelligent management method for a numerical control machine tool. The intelligent management method for the numerical control machine tool comprises machine tool operation authority management and machine tool real-time status monitoring. Used equipment comprises a control computer, a Siemens PLC (Programmable Logic Controller), buttons, an IC (Integrated Circuit) card reader, identity cards, numerical control machine tools with a barcode respectively, a barcode scanning gun and a numerical control machine tool controller, wherein the IC card reader and the barcode scanning gun communicate with the control computer through a USB (Universal Serial Bus), the control computer communicates with the Siemens PLC through an Ethernet based on an OPC (OLE for Process Control) method, and the Siemens PLC communicates with the numerical control machine tool controller through a Profibus DP (Decentralized Periphery). Through operation authority management, only authorized personnel can operate the machine tool and the intelligent management method is suitable for school teaching factories with large flow of people. Through the intelligent management method, by using a computer for recording the status data of the machine tools during operation, the statistical data is accurate and a reference is provided for fault diagnosis. The intelligent management method for the numerical control machine tool has the characteristics of high practicability, easiness in popularization and the like.

Description

technical field [0001] The invention relates to a method for intelligent management of a numerically controlled machine tool, in particular to a method for controlling the servo enable of the numerically controlled machine tool and monitoring the real-time running state of the machine tool by using an identity card. Background technique [0002] The modern machinery manufacturing industry uses a large number of CNC machine tools as industrial master machines, but lacks effective management of machine tool operation rights. At present, machine tool authority mainly includes program editing authority and parameter setting authority. Taking FANUC CNC system as an example, the former can limit the addition, deletion and modification of processing programs through the key switch on the machine tool. The latter takes Siemens CNC system as an example. By typing Authorization password SUNRISE, CUSTOM, etc., to access or change machine data. But at present, there is no method to res...

Problems solved by technology

[0003] In addition, the actual running time of CNC machine tools is an important indicator to measure the utilization rate of equipment, and the statistics of equipment utilization rate by artificial means has the disadvantages of inaccuracy and other shortcomings

[0004] In addition, machine tool operators generally do not have the ability to diagnose faults in CNC systems and machine tools. Often because machine tool maintenance technicians are not on site and lack records of machine tool real-time status data, it is difficult to quickly locate machine tool faults. As a result, maintenance time is prolonged and maintenance costs are increased. Reduced equipment utilization
