Need Help!- REWIND AND REPEAT PROGRAM

[CNCBEN]

I WAS WONDERING IF INSTEAD OF GIVING AN M30 COMMAND I COULD GIVE A COMMAND THAT WILL ALLOW THE MACHINE TO REPEAT THE PROGRAM X NUMBER OF TIMES BEFORE IT STOPS. IM USING A BAR PULLER SO IT WOULD BE VERY HELPFULL IF I COULD PUSH GO AND WALK AWAY.

Make your program a subprogram or a subroutine and then call it with an L count.

It depends on the machine which is easiest for instance on a Haas this works:


O00000(Bar puller progra,)
All the normal stuff to set up initial conditions
M97 P1000 L10
G28
M30
-----
N1000

This is the part program including the bar pull operation.

M99


This cycles through the part program 10 times and then stops.

Hi

Below is the solution. Use macro call below codes will run the program for 10 times

N0....start of the program
.
.
G65 H02 P#100 Q#100 R1 ( this balock will add 1 input in the variable #100)
G65 H82 P0 Q#100 R10 ( this block will see that variable #100 is equal to 10 or not
if it is not equal then it will go to N0
if it is equal then it will go to next block)
G65 H01 P#100 Q0 ( in this variable #100 is made equal to zero)
M30 (end of the program)

The above sample i had used for running the program 10 times i.e. for 10 jobs.
H02 is for addition
H01 is for equal
H82 is for conditional divergence.
