Method for calculating operation rate of machine tool based on OPC technology

Abstract

The invention discloses a method for calculating the operation rate of a machine tool based on an OPC technology. The method comprises the folleoing steps: A, the machine tool operation state is redefined as the fault state, the abnormal state, the idle waiting state, the processing state, the debug state and the shutdown state; B, the definition of each operation state of the machine tool in the step A is written into the software in the form of a mathematical model; the software calculates the actual operation time of each operation state of the machine tool through the mathematical model and makes statistics and storage; and then the time operation rate and the efficiency operation rate are calculated; and C, multiple calculation results of the step B are transmitted to an application/display terminal. The operation state of the machine tool is redefined into six more accurate states and the accurate operation state data of the machine tool are obtained through calculation of the real-time data; all the data are collected and calculated automatically in real time; and the time operation rate and the efficiency operation rate of the machine tool are more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of machine tool state monitoring, in particular to a method for calculating the utilization rate of machine tools based on OPC technology. Background technique [0002] Traditionally, the operation status data of CNC machine tools, robots, and automated production lines collected by DNC or NI technology use the three-color light signal as the basis for calculation. However, the judging conditions for the signal output of the three-color light are set by the programmer of the equipment manufacturer, and there is no uniform standard, which is relatively random. Generally, the three colors of the tri-color light are: red for failure, green for processing, and yellow for idle. However, such a definition cannot correctly reflect the actual situation of the machine tool, and the error is relatively large. For example: the machine tool is in the state of automatic operation, the spindle is rotating, but the feed ...

Problems solved by technology

However, such operations of workers are actually working or preparing for production effectively. For discrete manufacturing, this kind of machine tool operation data is the basis for employees' performance working hours. Since the existing methods cannot solve this problem, the real performance working hours are only It can be recorded manually, and there is a problem of data error or data falsification

[0003] The utilization rate of the machine tool has a great relationship with the operating state of the equipment, and the existing definition of the operating state cannot fully reflect the operating state of the machine tool, which makes the recording and statistics of the operating state data inherently flawed, resulting in the existence of the machine tool utilization rate. inaccurate question
