The teaching experiment of teaching type CNC engraving machine

According to the specific requirements of nc practice teaching of higher education, combining with the characteristics of the structure of the CNC engraving machine experiment system, follow the principle of unit 1, step by step, the following two experiments is designed. 1) CNC programming experiment. Practice has proved that the use of the numerical control processing equipment effect depends largely on the nc machining program compiling level. Mechanical professional colleges and universities graduates on jobs, there are quite a number of engaged in the operation of nc machine tools. To cultivate and improve the students' programming ability, in this engraving machine experiment system, open nc code programming experiment. This system used in engraving software with functions of automatic programming and manual programming. Among them, the manual programming support routine G code, M code output, convenient students use theory class programming practice what they have learned content. Software main interface with simulation function, that is, by means of computer graphics, to simulate the process of machining tool and parts cutting. In the process of simulation, the student can also be from the main interface display real-time observation of the coordinates of the tool coordinate change. So that the students can see the engraving process in advance, found in the process of carving, effectively predict the reliability of the nc machining and cutting process. 2) Carving machining experiment. CNC engraving machine experiment system design in accordance with the requirements for engineering use, can complete calligraphy, small circuit board processing, etc. When making sculpture processing, students need to master the workpiece installation, sculpture, parameter Settings, processing software, and other important link of the operation, the experiment can provide students with training from the practice of numerical control programming to nc machining. After a series of parameter setting, to introduce the process of programmed application area, carving processing can start. Students in the process of tool operation, through the simulation function combination processing field, real-time attention to the whole machining process. In an emergency, can press 'stop' button of main interface, the processing and pause.
