I am machining some low carbon steel (around 15 Rockwell C) and for some reason it is giving me absolute hell. I am using the dynamic area milling toolpath, using a 3/4 AlTin coated carbide with a 1.5 L.O.C.. As far as my parameters, I have my D.O.C. at 1.375 and my W.O.C. at about .060. What should I be running my feeds and speeds at with that low radial engagement? Or should I adjust my W.O.C.? Also I am using a Haas TM-2 so not a whole lot of power.
Hello. I am extremely new to Mastercam, so forgive me if I don't make a lot of sense. I am working on a lathe part that also requires multi-axis milling. I've been tackling it for quite some time now. It is very important to note that I am doing this for work and on a company laptop. Said laptop is also being used by other programmers, for other machines (I am trying to program this part for an OKUMA.) When I tried to post my G-code yesterday, I noticed that the feeds for the multi-axis milling portion of the job had drastically changed. I am talking a difference of about 100-150 (I am not quite sure where to see what the units are). I did not make any changes to the program, I even tried posting the code from a similar (almost identical) project that I know was using the correct feeds before. Same thing happened. My theory is that one of the other programmers made a change to the software that I am not aware of. The code, however, seems to be ok- seems to be generated for OKUMA. Any ideas?
Newby here - first post. We purchased a Hardinge GX1000 with a Okuma OSP200M controller, and MasterCam for Solidworks. Went to training. Wrote some good programs in MasterCam for SW. Posted them to G codes. Speed and feeds are always wrong. Seems that the feed is 10X faster than the spindle speed cutting tool than what MasterCam says. We have broken a few $50 bits, so no one is really happy. Seems we just can't get our speeds and feeds correct from MasterCam. So we purchased the CNC Cookbook calculator for $70. The CNC Cookbook helps us with correct speeds and feeds, but is really addressing the symptoms, but not the root problem. Anyone else have this type of problem? I hear that our Hardinge/Okuma machine is a one of a kind hybrid at this point and this might be part of the problem. Any help if fully appreciated. - Phil
