The implementation of programming training CNC programming is an important part of CNC technology teaching. CNC lathes are programmed using common G codes. First of all, the instructions of the G code must be explained clearly, so that the boring CNC instructions become an interesting symbol game, and stimulate students' interest in learning. Through continuous programming exercises, practice makes perfect and strengthens the cultivation of students' programming skills. Of course, the procedures written by students for the same part may be varied, and teachers should carefully correct student assignments and identify problems to correct errors in a timely manner.
Test the program and run it empty or test it with a nylon rod. Because the cost of the CNC equipment is relatively high, the program must be inspected before processing, otherwise it is prone to accidents. First enter the program into the CNC machine, then let it run empty, observe the change of the machining position of the tool along the defined trajectory. Since this type of CNC lathe can not be simulated, we use nylon rod for trial processing. During the trial processing, students can observe the whole process of CNC machining. Students can check whether there is a problem with their programmed program and deepen their understanding of the machining process.
Practical machining with a CNC lathe After all the preparations are ready, we will actually machine the parts. First of all, it is necessary to accurately match the knife and input the value of the tool so that the processed parts can meet the requirements. Set the machine to "automatic" and the CNC lathe is machined. The traditional mechanical processing technology is linked with the modern numerical control technology, which makes the students feel that the previously learned knowledge is no longer isolated, which not only deepens the students' knowledge of the processing technology, but also achieves the purpose of numerical control teaching.
