Vad är m99 cnc M99 has three main uses: M99 is used at the end of a subprogram, local subprogram, or macro to return back to the main program. An M99 Pnn jumps the program to the corresponding Nnn in the program. An M99 in the main program causes the program to loop back to the beginning and execute until [RESET] is pressed. Haas. calling program. 1 g-koder 2 Nearly everyone has used an M99 in their CNC programs, but chances are, you didn't know that it has several different uses. That's right, not only does an M99 LOOP back to the beginning of your program, but it can also JUMP to another spot in your program, or RETURN back from a sub-program. 3 cnc programmering utbildning 4 M98 and M99 G-Codes: Subprogram Calls Let’s start out with Subprogram Calls, because they’re a little simpler to understand than Macro Calls, albeit less powerful. A subprogram call is pretty straightforward. 5 M98 and M99 G-Code subprogram call W e can call upon subprograms within our main CNC program to run tasks. This saves time by running a task that is often repeated by storing it in memory. 6 M Subprogram call function. M Subprogram end function. Subprogram call function M98 must always be followed by the subprogram number P–. Subprogram end function M99 terminates the subprogram and transfers processing back to program it originated from (a main program or a subprogram). 7 cnc-fräs 8 Nästa alla har använt en. 9 M99, Subprogramåterhopp eller slinga. 10 de typer av kommandon som är programmerade i en CNC-maskin. M-koder är en viktig del av driften av en CNC-maskin. Medan G-koder beskriver positioneringen för en operation, ger M-koder data för en maskins handlingar. För att en CNC-maskin ska fungera korrekt måste g-och M-koder anges. 11 As an unconditional branch command (like a GOTO statement) In a main program (not a sub-program), an M99 can be used to change the order of program execution. A P word within the M99 command tells the machine the sequence number (acting as a statement label) to which to branch. The command. N M99 P 12
