arc & cutter compensation was created by MaxEkb77
Hello i try use cutter compensation with g2/g3 arc.
Hole 10mm diameter cutter 9.9mm
In tooltable say we create a tool diameter.
I look into interp_convert.cc convert_arc_comp1 i got tool_radius = settings->cutter_comp_radius;
in convert_cutter_compensation_on radius = USER_TO_PROGRAM_LEN(settings->tool_table[idx].diameter) / 2.0
.
ok fine

This discussion may shed some light on the matter:

Not sure what exactly you are trying to mill but if you want to mill out a circular pocket then I would recommend using a helix with a tangential lead in. This will give you a much better surface finish.

Interesting link.
my problem - many program from fanuc - to much time to rewrite it all.
Linux have many shortway aka g2i3z-10p10 on fanuc more 300lines code.
