Method for online managing cutting tool of numerically controlled lathe

Abstract

The invention discloses a method for online managing a cutting tool of a numerically controlled lathe, which comprises the following steps: firstly, setting up a device for online managing the cutting tool of the numerically controlled lathe, establishing a database on a cutting tool management server and developing a corresponding functional module interface on a lathe tool magazine terminal; formulating a subprogram on the numerically controlled lathe according to programming rules adopted by the numerical control system; and by using the cutting tool management server, receiving and transmitting information between the lathe and the cutting tool management server by calling a function in a serial port server, processing read program data, modifying or querying the database and transmitting the queried information to the corresponding numerically controlled lathe. Through the method, the information about the cutting tool is accurately recorded and queried by networking all machining centers and lathe tool magazine terminals so as to shorten cutting tool replacing time, make full use of the residual life of the cutting tool, save human resources and improve production efficiency.

Description

technical field [0001] The invention relates to industrial automation management, in particular to an online management method for CNC machine tools. Background technique [0002] With the development and wide application of CNC machine tools (machining centers), the tool management of CNC machine tools has attracted people's attention day by day. A machining center or CNC machine tool usually stores dozens of tools in its tool magazine. In addition, in order to cope with different processing needs and tool wear and damage, a considerable number of spare tools must be stored in the workshop's central tool storage. Cutting tools, if an enterprise has more than five machining centers, then at least hundreds of cutting tools need to be managed. Generally, an enterprise has thousands of tools to manage, and the annual cost of tools is as high as several million yuan. [0003] Tool management includes the registration and search of tool information, the record of tool configura...

AI Technical Summary

Problems solved by technology

The traditional tool management method mainly relies on manual registration, which has problems such as heavy workload, poor real-time performance, and inability to record online information, resulting in too much time spent on tool management, which seriously affects the improvement of production efficiency

Foreign companies use computer management and barcode technology in tool management to manage information such as workshop tool magazines and tool sending and receiving, but there is still no online information about tools installed in machining centers or CNC machine tools, especially tool usage status information. management records

The online information of the tool reflects the real state of the tool. Without the online information of the tool, real tool management cannot be realized
