Embodiment Construction

[0029] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Note: For the sake of brevity, the machining centers and CNC machine tools are collectively referred to as "machine tools".

[0031] Process flow of the present invention is as follows:

[0032] One, set up as figure 1 The CNC machine tool monitoring system shown.

[0033] The system consists of a machining center (NC machine tool), a single serial port server, RS232 cable, network switch, Ethernet cable, server and client. The server and the client are respectively connected to the network switch, and each processing center is also connected to the network switch through a single serial port server. The single serial port server is connected to the processing center by RS232 cable, and the single serial port server is connected to the network switch by Ethernet cable.

[0034] There is an RS232 interface on the machining center, ...

Abstract

The invention provides a method for monitoring a numerical control machine, which comprises the following steps of: firstly, building a numerical control machine monitoring system; then establishing a database which is in a table format on a server; developing a corresponding functional module interface on a client; programming a numerical control program on the numerical control machine according to an adopted programming rule of a numerical control system; receiving information sent by the numerical control machine by the server through calling a function in a single serial port server; processing according to read program data; recording a workpiece drawing number and start time into the database; and recording a workpiece drawing number and completion time into the database. Accordingto the invention, the work of recording the workpiece drawing numbers, the machining start and completion time and machining working hours of workpieces when the workpieces are machined on the numerical control machine can be completed, the automatic recording is realized, and the has advantages of high speed, manpower resource saving and low cost are achieved.

Description

technical field [0001] The invention relates to industrial automation control, in particular to a monitoring method for a numerically controlled machine tool. Background technique [0002] The value of CNC machine tools is high. To give full play to their utilization, we must try our best to arrange the processing process to reduce the waiting time, that is, to optimize production scheduling. However, this requires real-time grasp of the processing status of each CNC machine tool and the working hours of the workpieces that need to be processed in the future. Different man-hours must be recorded for each workpiece processed on different machines. Moreover, in order to ensure the on-time delivery of the contract, it is necessary to predict the delivery time of the workpiece, and it is also necessary to record the actual processing time of all workpieces on the relevant equipment. [0003] At present, in order to obtain the processing time, the technical quota method, the sta...
