IPM in g-code is same as tool spec

[steveBKDRW]

I'm cutting (wood) 3D adaptive using a 1/4" ball nose with supplier spec of 160 ipm and 0.004 feed per tooth. My passes are at 0.0375" stepover. In the g-code it is still 160 ipm when the tool isn't working much. Is there a way to get the ipm to use chipload based on the amount of material?

No

Adaptive only has one feed rate available for all cutting moves.

Do any of the other toolpaths vary feed rate based on the cutting load?

FWIW, I have manually turned up the feed rate at the machine and not had a problem. Although I still don't know if I'm optimum.

Rethinking, is there any manual calculation to adjust the feed rate in the setting of the file to account for the step over?

[a.laasW8M6T]

No

All the toolpaths have one cutting feed, the lead in and ramp and transition feeds can be different but you cannot vary the cutting feed based on load or other factors.

I believe this is possible in some software's that cost many 10 of thousands of dollars(Hypermill)

[a.laasW8M6T]

Yes

 You can do that however

I use this app https://app.fswizard.com/ for calculating feeds and speeds based on different tool stepovers/DOC.

I haven't ever cut wood though so don't really know how well that would go.

160ipm means nothing without spindle RPM

I'd easily run a 1/4 EM in wood at 200ipm 16k rpm at a much wider stepover. 15% isnt going to give you a good finish, so I think youre just roughing anyway? Just manual over ride on your controller until a tool breaks then back off 15%
