加工中心编程技巧和安全（Machining center programming skills and safety） Machining center programming skills and safety release date: 2011-01-19 source: mechanical expert network With the development of science and technology and the progress of the society, the technology of numerical control machine tools has been developing continuously, the function is becoming more and more perfect, the use is more and more convenient, the reliability is higher and higher, the performance price is higher and higher. The application of CNC machine tool has been popularized to a certain extent, and the high performance high efficiency machining center has gradually become the requirement of society. Through the practical application and teaching practice of several years of processing center, I will share some accumulated experience with readers. If there is any mistake, please criticize it. 1. Programming skills of several commonly used instructions in the processing center 1. Differences and connections between M00, M01, M02 and M30 When students are programming in the process center, it is easy to confuse the above M code, mainly because of the lack of knowledge of the processing center and the details of the individual textbook. Their differences and links are as follows: The M00 pauses the instruction for the program. The program executes this feed to stop, the main axis stops. Repress the start button to continue the program section later. Mainly used for programmer to suspend machine tool (inspection piece, adjustment, etc.) in machining. M01 gives the program selective pause instructions. This function can only be valid if the select stop key ON the control panel is in the ON state when the program executes, otherwise the directive is not valid. The effect is the same as M00, often used for critical size inspection or temporary suspension. M02 is the end of program instruction. Execute to this command, feed to stop, spindle stop, coolant shutoff. But the program cursor stops at the e
