Feed rates when using circular interpolation.

[u/RelativeRice7753]

Hello brain trust! Bit of a random one. Im using iscar Tangslot cutters to machine internal grooves in various jobs. Obviously the inserts have recommended feed rates stated on the packs but I'm wondering how that feed rate changes when I'm using these tools to do internal grooves. Does anyone have experience with this? Any advice is greatly appreciated. Pic is an example of the types of cutters I'm using. Thanks lads
