Re: [mfg-smartcam] Machining help

could not find HD17 but all of the Tungsten groups call for In the Machining Data Handbook.   .020 depth of cut 200 fpm  carbide only .060 depth of cut 150 fpm  carbide only   drilling carbide grade C-2 150-200 fpm at .002 IPR   Note:     Due to the brittleness of refractory alloys, cracking, chipping, flaking and breakout tend to occur, particularly on the edges of the machined surfaces.   Hope this helps I never worked with it.   Dave Wolfgang CNC Programmer/Supervisor www.hrindustries.net ----- Original Message ----- From: Terry Keene To: SmartCam Forum Sent: Friday, March 26, 2004 2:32 AM 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
