I have a part to machine that is Maraging steel 300 which is like 17-4PH. My plan is to use a Sandvik VCGX 11 02 02-AL H10 which has a small radii and sharp. We only have to rough the part as it will be finished with several OD grinding ops. Probably leave .015 on each surface. The material is .500"Ø and in the soft state. The plan is to hold in a steel jaw air chuck and a center in the tailstock and machine from the center to the chuck, then flip and repeat. Final diameter in the center is about .220". My concerns are chatter and tool life. Sandvik recommends 200-300 SFM and .004"-.008" feed. Not sure on depth of cut but it can't be too much because of cutting pressure. Just 15 parts so speed not and issue only tool life. Any thoughts?
The image shows the tool path and insert cutting one half just over 4.000" long. The total length of the part is just under 9.000" long.
