Stuck getting a G83 to work.
Stuck getting a G83 to work.
(OP)
I'm trying to get a parametric program running on our Mazak Integrex 200Y, and I'm struggling to get a G83 cycle to run on it.
Here's the code I'm using:
T0600.0
M169
M212 (LOCK C AXIS)
M13 (SWITCH TO MILLING MODE)
G00 X0.0 Z5.0 (START POSITION)
G83X0.H0.Z[#7+5]R5.Q1400.P0F150L1M210
G00 X0.0 Z5.0 (BACK TO SAFE POSITION)
G80 (CANCEL HOLE CYCLE - RESETS MODAL VALUES)
It's a mill-turn machine, so the 'H' in the G83 controls the C axis. The #7 value is -38.42, and the M210 locks and unlocks the C axis at the beginning and end of the cycle. (The M212 in in there as that's what the operators recognise as spindle lock)
What happens is the tool comes in as far as the G00 line, starts rotating, and begins the G83. The position screen comes up with how far the tool has to go, but it just sits there without moving. I'm fairly new to using canned cycles as our post processors are set up to throw everything out 'long hand' so I'm a bit stumped why this doesn't work. Any suggestions?

Right, off for another play...

Isn't Q the amount you want to cut in with each peck? If so, the value of 1400 doesn't seem to relate to the depth of the hole at -38.42 to me. That might also explain why the feed seemed so slow (1400/150=9.3minutes).

One of those 'doh' moments. I didn't have a spindle speed in there: added M203 S180 at the top, and off it went quite happily.
Surpised it worked on the machined backplotter though, and just hung (with the tool rotating?
Thanks everyone.
