I would like to hear opinions on the use of RAMP, SPIRAL and PLUNG as lead-in to interior pockets. I have almost exclusively used the Spiral technique mostly due to small pockets with limited space but recently I have been working on parts with large interior pockets and started wondering what advantage (if any) using a Ramp technique would have. Plung does not seem very practical unless there is no choice because it is so hard to clear the chips from the cutter. Plung might make more sense if I had a high velocity flood coolant delivered through the tool but I only use a Fog Buster type. Thanks for your thoughts on this?
