加工中心编程说明资料2（Machining center programming instructions 2） With the development of science and technology and social progress, people on the performance and product quality requirements are increasingly high, so that the application of NC machine tool has gained popularity to a certain extent, and the processing center of high performance and high efficiency has become a social need. Through the actual application and teaching practice and exploration of the processing center for several years, the author summed up his experience and experience, hoping to enlighten the readers. 1. pause instruction G04X (U) _/P_ refers to the tool pause time (feed stopped, spindle does not stop), the address P or X is the value of the pause time. The value behind X should be accompanied by a decimal point. Otherwise, 1/1000 of this value is calculated in seconds (s), and the value in P cannot be followed by decimal points (i.e., integer representations), in milliseconds (MS). For example, G04 X2.0; or G04 X2000; pause for 2 seconds G04 P2000; But in some holes processing instructions (such as G82, G88 and G89), in order to guarantee the roughness of the bottom of the hole, when the cutter to the bottom of hole required when the pause time, at this time can only use the address of P said that if that address X, then the control system that X is to carry out the value of the X axis. For example, G82X100.0Y100.0Z-20.0R5.0F200P2000; drilling (100.0100.0) to the bottom of the hole for 2 seconds G82X100.0Y100.0Z-20.0R5.0F200X2.0; drilling (2.0100.0) to the bottom of the hole will not be suspended. The differences and connections between 2.M00, M01, M02 and M30 M00 is a program with unconditional pause instruction. The program executes to this end of the feed, and the spindle stops. Restart the program, you must first return to the JOG state, press CW (spindle is turned) to start the spindle, and then return to the AUTO state, press the START button to start the program. M01 suspends instruc
