Bridgeport ROMI Powerpath G-code question

Hello all,

Let me begin by saying I am by no means an experience programmer.

I’m hoping someone with a little more knowledge and experience than I can help me out. I run the machine mentioned in the title most days and I’ve been trying to figure out the G-code for CSS. Of course I know that G96 should enable CSS and G97 should turn it off, but I’m not having any luck with this actually working. It is the dx-32 control and a google search brought up mostly g code for milling, so not much help.

I would really appreciate it if someone could provide some insight, or even better a couple lines of known working code for me to reference.

I'm just flipping shit at you as I have no knowledge of that control. Are you calling an "S" with your G96? G96 S400 normally sets the constant surface feed at 400. Sometimes depending on the control you need to give a diameter along with the G96. On an Acromaitc control you call a G96R2.S400 the "R" is the diameter at which the tool is sitting when you turn on sfm.

G97 is a constant speed, G97 S400 will spin at 400 rpm regardless of what diameter the tool is sitting at. The most important thing to know about G96 is to limit your rpm at something your gripping or work holding situation will comfortably handle, typically with a "G50 S800" or "G92 S800" depending on the control.

You have no books or examples of working programs?

If running in DX32 mode -

G38 is Spindle Speed Clamp
G37 is Constant Surface Speed
G36 is Constant RPM

If running in Fanuc mode -

G92 is Spindle Speed Clamp
G96 is Constant Surface Speed
G97 is Constant RPM

And until you get a good feel for the machine, just stay away from G28/G53. It's an oddball handling that most people crash it with.

Good luck.

A huge thanks to both of you who replied. I really appreciate the help. As I’m sure you understand, it’s hard to find time during the day to experiment on the machine (ie waste time), so this info will save quite a bit of trial and error.

Again, thank you.

Edit: g36 g37 and g38 did the trick. Running perfectly.
