hello all im currently uing a kia superturn 28 with a fanuc controller and ive run into a problem regarding trying to cut an inverse angle using a g71 canned cycle. for ex (cutting / as opposed to \). first ill show you my trial program then explain what it is doing.
G96 S400 M3;
G0 X5.1 Z0.05 M8;
G71 U0.075 R0.01;
G71 P101 Q102 U.01 F.01;
N101 G0 X4.98;
G01 G42 Z0.0;
G03 X5.0 Z-0.01 R.01;
N102 G0 G40 Z0.05
Basically instead of breaking up the machining of this piece up into the depth of cut specified (0.075) it tries to cut the whole angle at once. I had someone tell me to add a Z0.05 on the N101 line and removing the Z on the N102 line he got it to work on his machine. he was using a HASS. i tried that myself but i kept getting an illegal g code alarm. if anyone knows how to accomplish this on a kia it would be greatly appreciated. as of now i use that canned cycle but manually change the offset on the X geometry of the tool being used and make my own depth of cuts. on smaller pieces i use a g72 canned cycle with a groove tool to do such an angle. there must be a way to get a turn tool to do this on my kia. any insight on this matter would be greatly appreciated.
The addition of a Z or W on the start line continued to alarm the machine out. Keeps telling me illegal use of gcode alarm. Could it b this machine is too old?
I'm using a t of 3 for the tool being used on the geometry offset page could this b why? Other then that I'm running out of ideas.
Tried the same program on one of our newer machines a super kia turn 15lms and it worked like a charm. Any idea why it wouldn't work on the other machine.?
Have you ever run a G71 - G76 on the machine? Maybe the option isn't turned on?
Yes I have ran g71 g72 g74 g75 and g76 on this machine. taking out the z on the first line runs the program but all in one shot. Adding the z causes an alarm on this machine. U may b right, perhaps a key parameter is not turned on in this machine.
