Embodiment Construction

[0050] The present invention will be specifically described through embodiments below in conjunction with the accompanying drawings.

[0051] Note: For the sake of brevity, the machining centers and CNC machine tools are collectively referred to as "machine tools".

[0052] Process flow of the present invention is as follows:

[0053] (1) set up as figure 1 The CNC machine tool online management system shown is composed of a machining center (NC machine tool), a serial port networking device, an RS232 cable, a network switch, an Ethernet cable, a tool management server, and a tool library terminal in a workshop. The tool management server and the tool magazine terminal in the workshop are respectively connected to the network switch, and each CNC machine tool is also connected to the network switch through the serial port networking equipment. The serial port networking device is connected to the CNC machine tool through RS232 cable, and the serial port networking device is ...

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...
