It would be great if someone can help me with the cutting parameters, peck depth (Q) and things like that to produce a hole of size 15.870mm(.6248"). This is a thru hole and the depth is 101.6(4.0"). HSS Drill size is15.5mm(.61") and brazed carbide reamer is 15.870mm(.6248"). Material is 4130 QTT. Which drilling cycle would be good?? Inputs on feed, speed, peck depth are welcome so that the cutting time is reduced.
