Feeds and speeds for engraving tool in titanium

[FTI2007]

I need to cut a cross hatch pattern that is .200 wide by about 6" long .017" deep with a .125 x 90deg (2 flute .005 tip) AITiN coated engraving tool. I will be plunging off of the part. What should I use for a depth of Cut. According to Harvey Tools site I was going to start with 10,000rpms and 5ipm which is .0003 fpt. Not sure if I should go slow and deeper or faster and lighter. Only have 1 Part to make and have 4 cutters to get thru it. Thanks

I'd go 3 depth cuts roughing at the speeds and feeds listed leaving a .002" finish depth of cut. If you have thru spindle coolant available you could probably double your chip load no problem.

well I tried .007 doc and that didnt work to well. I am now runing .0035 depth of cut and so far so good. Also looks like the engineer was wrong about the .017 depth and it is only about .009-.01 so thats good. I will update more later.

I had to run at 12000rpm and 4ipm at 3.5doc and that seemed to work. just real slow.
