Control program modularization system for numerical control machine

Abstract

The invention discloses a control program modularization system for a numerical control machine. The system comprises a human machine interface (HMI). The system is characterized in that: a numerical control machine control program system in a numerical control unit (NCU) is subdivided according to each functional program and reflected in a module form; a function selection parameter number checkmodule is stored and set inside a programmable logic controller (PLC) of the system; a basic function library module contains control logic programs of corresponding sub functions after the function of the numerical control machine is decomposed; a storage data and system start module, an axis control module and an auxiliary function selection module in the PLC are called for data processing and selection and start of corresponding functions; and an input / output signal mapping module is used for logic processing between the internal storage data and the actual input / output signals. The related functional modules are called by function selection on the HMI, so that a certain functional program can be complemented or modified, the production efficiency of the numerical control machine is improved, the fault rate of the numerical control machine is reduced, and the reliability of the numerical control machine in actual use is enhanced.

Description

technical field [0001] The invention relates to the field of automatic control, and is used for a control program modular system for numerical control machine tool control and motion control. technical background [0002] In the control process of CNC machine tools, a lot of control program compilation work is often required, and there is a contradiction between the current traditional programming methods and advanced control application requirements. At present, there is no clear and unified standard for the inspection of the quality of control programs. In actual projects, the control quality is often judged based on the final execution results. As a result, the compilation of control programs has become a very personalized work, and each control program has a lot of randomness. This has caused great obstacles to the mutual exchange of CNC machine tool control programs. This situation is even more serious when a CNC machine tool hardware structure is divided into several d...

At present, there is no clear and unified standard for the inspection of the quality of control programs. In actual projects, the control quality is often judged based on the final execution results. As a result, the compilation of control programs has become a very personalized work, and each control program has a lot of randomness. This creates a big obstacle to the mutual exchange of CNC machine tool control programs. This situation is even more serious when a CNC machine tool hardware structure is divided into several different functional parts and programmed by different personnel.

This state greatly hinders the improvement of the level of control programming and the later production debugging and equipment maintenance. At the same time, the control effect of CNC machine tools is also difficult to be well guaranteed at the programming level.
