Terry   While I don't have experience cutting it I do have the machining data handbook so it's a place to start... I've got the 3rd edition and it's a few years old but so is our equipment. the HD17 isn't in the list so here's a rundown of what there is with C2 carbide. If these don't work for you the cutting tool manufacturers will likely have something that will perform better and many are happy to visit and help solve a problem with you.   hardness 180-320 Bhn they say 200 sfm with .020 radial depth of cut .003 itp for cutters larger than 3/4 dia 180-320 Bhn they say 150 sfm with .060 radial depth of cut .003 itp for cutters larger than 3/4 dia   alloys anviloy 1100 - 1150 - 1200 290-320 Bhn they say 550 sfm with .020 radial depth of cut .001 itp for cutters 3/8 dia and up to .003 ipt for 1" dia 290-320 Bhn they say 425 sfm with .060 radial depth of cut .0025 itp for cutters 3/8 dia and up to .004 ipt for 1" dia 290-320 Bhn they say 365 sfm with dia/4 radial depth of cut .0015 itp for cutters 3/8 dia and up to .003 ipt for 1" dia   hope it helps, Jeff   -----Original Message----- From: Terry Keene [mailto:[EMAIL PROTECTED] Sent: Thursday, March 25, 2004 11:32 PM To: SmartCam Forum Subject: [mfg-smartcam] Machining help Since the traffic on this system has been so light.  How about some help with an off-subject question.  We have to mill some tungsten alloy HD17.  It's some kind of a heavy metal material.  Anyone have any experience with the material?  Some help with speeds and feeds on profile milling with powdered metal or carbide tooling would sure help. -Terry
