Okuma P300 Fast-tract Tapping cycle; changing retract plane causes dwell.

[danielm]

 

I'm trying to optimize cycle times and have found that if the retract height gets changed between holes, the G284 (fast tapping cycle) gets interrupted, causing a short dwell.

Has anyone run into this?  Does anyone know of a parameter in the P300 control that will prevent the G284 from hiccuping resulting in a dwell?

 

heres a snip of the code:

 

G284 X1.4 Y-198.8 Z114.75 R128.95 F4000. M53
G71 Z97.5
G284 X-11.05 Y-36. Z83.3 R97.5 F4000. M53

 

 

Thx!!

Dwell is needed to synchronize the Spindle to the Z axis since that has changed. That is pretty much the same thing on a lot of machine where they establish an encoder position to a set position on one of the axis. You make a change the machine needs to re sync the encoder to the position and go from there. Not sure you really want to change what you think you want to change.
