数控宏程序入门（Introduction to NC Macro Program） Macro program order Everyone is asking the macro program ~ in fact macro is used the formula to machining parts, such as ellipse, if there is no macro, we want to point out a point on the curve, and then slowly with a linear approximation, if a workpiece finish demanding it, then the need to calculate a lot the application of the macro point, but after we put the ellipse formula into the system and then we give the Z coordinate and 10um so every macro will automatically calculate X coordinate and cutting, actually a macro to mainly in the program operation is generally divided into a macro. Macro and B macros. Macros are class a G65 Hxx P#xx Q#xx R#xx to the input format, while B is a macro program A direct formula and language input, very similar to the C language, is widely used in 0I systems because of the large amount of B class macro programs With a lot of books have been introduced here, I will not repeat it, but in some of the old system, such as Frank OTD system because there is no formula symbols of the MDI keyboard, equal numbers are not even the most simple, so if the application class B macro program it in the computer numerical control system through the good RSN-32 interface, but if we do not PC and RSN-32 cable it, so only through a macro program for the macro program, I introduced the following quote a macro; G65 Hxx P#xx is a macro Q#xx R#xx or G65 Hxx P#xx Qxx Rxx XX means the input format is input to UM value, the amount of, if you enter 100 that is 0.1MM~~~~~.#xx is variable, a variable number and do not know what is the meaning of the words I do not rule, but or teach me, is put into the numerical variables, a fixed address, a fixed address is variable, the general OTD system in #0~~~#100~#149~~~#500~#531 power off when the variable #100~#149 is initialized to empty, and keep the variable #500~#531 data. If we say #100=30 now #100 address within the data is 30 that is so simple. Now I look at the H code,
