curve 5 axis

The lead in move on my curve toolpath is using my plunge feedrate? Anyone ever seen this before?

It is happenning on multiple curve toolpaths, I see the plunge feedrate on my lead in move in backplot and in the posted code....

Hi Keith,

 

Yes, the toolpath should use the Plunge Feedrate for the entry move into the cut. If you turn off "Rapid Retract", then the toolpath will use your "Retract rate" for the Lead Out move.

It is using the plunge feedrate for the approach (which is correct), and the lead in move (where cutter comp would be applied during a standard 2d contour, which is not correct), but the lead out move runs at programmed feedrate (not the plunge feed.)

I want it to use the programmed feedrate for the lead in move, the cut, and the lead out....

here is a file, backplot the path and watch the feedrate for the lead in move.....

Keith,

 

What you are describing is the way it works. The Curve 5X Path applies the Plunge Feedrate to the Lead In move, and the Retract Rate to the Lead out move (but only when the 'Rapid retract' checkbox is disabled). Try disabling the 'Rapid retract' checkbox and you will see the difference in backplot and in the posted code.

 

That is the way the 'Curve 5X' path works.

 

If you want different options than that, then use the 'Wireframe' option in the toolpath selection dialog, and choose 'Cuts along curve'. This is like a 'Curve 5X' path, but the underlying code is from ModuleWorks, instead of the older CNC Software developed 'Curve 5X' path.

 

With the 'Cuts along curve' path, you get all the different 'Linking' options. These options give you the ability to override the feedrate value on the entry move, as a percentage of the cutting Feedrate.

Thank you Colin, do you agree that this seems wrong?

 

Also, If you still have the file, it seems to be ignoring the feed plane and rapiding to the retract height, then feeding down from the retract...... weather I have clearance checked or not....

No big deal, easy to get what I want.

 

I never paid attention to weather or not it did what I thought was right, always just throwing stuff at it to get what I want in the posted code. LOL

I think there is room for an enhancement, so I would suggest sending in an enhancement request to QC to add a separate feedrate control (or maybe just a checkbox: use plunge rate in Lead In?) for the Lead In/Out moves.

She is definitely not respecting the feed plane.
