I have a 1999 Romi M17 with a 21iT control. I use a Dorian wedge-style toolpost. I am using a tool which one side is used to turn the OD, then the other side turns the ID. The problem I'm having is the machine stops and waits for a tool change when I would like it to just automatically change the offsets and continue machining. I'll give an example of the spot in the program:

T1111 (OD);
M3;
M8;
G42 GO X1.30 Z.05;
G70 P1 Q2;
G40 G30 UO WO;
T1212 (ID);
M3;
M8;
G41 G0 X1.00 Z.05;
G1 ZO.O F.002;
X.96;
X.942 Z-.009;
Z-.250;
G40 X.880;
G0 Z.5;
G30 U0 W0;
M1;
M30;
%

Usually, I would add a M1 after the G30 U0 W0, and this stops the machine.
I just always thought that was what it did.
Any ideas on what I'm doing wrong? Do I need to adjust a parameter?
I would really like to have the machine continue on it's own without having to push the tool change button.

Thanks

Usually when you use two offsets for one tool, only the last 2 digits change (so it doesn't index). Try

T1111 (OD)
T1112 (ID)

dcoupar, I am pretty sure that I tried that on Friday. I'll make sure that I try it tomorrow and see where it goes.
Thanks

Usually the last (rightmost) two digits of a T-word specify the geometry as well as wear offset numbers (which are row numbers of the respective offset tables), and the remaining digits (one or two) at the left designate the tool number on a lathe. The numbering scheme for geometry offset, however, depends on a parameter setting. Though the leftmost two digits always designate the tool number, a different parameter setting will cause these digits to be interpreted as geometry offset number also. The rightmost two digits are always wear offset numbers.

Hi,

May I know if you have got the solution. I am interested in it. Please do let us know how did you address this problem.

Thank you,
