CNC opeator can calculate feedrate for inside arcs using this formula:

Fi = Fl * (R - r) / R;

where
Fi - Feedrate for inside arc,
Fl - Linear feedrate,
R - Inside radius on the part,
r - Cutter radius.

To calculate the feedrate for inside arc enter the linear feedrate, inside radius on the part, cutter radius and click the CALCULATE button.

The program will calculate the feedrate for inside arc.

  Fl =       

 R  =     

 r  =      

 Fi =
