Hi
I'm working on a little engine project where we plan to use normal tool grade carbide to balance a crankshaft.
But to get the design as close to reality as possible we need to know the density of carbide. I've found many different spec depending on the carbide type. I just the the density of the type you get from your normal tool grinder as this is the type we plan to use.
Metric values are prefered
CNC din't drop support for Volumill. They just cancelled the free mastercam seat Volumill had in order to develop their c-hook. Volumill could have continued development if they just purchased their own seat of mastercam. I guess volumill calculated that this seat would cost more than what they could earn on selling new volumill c-hooks.
Adaptive clearing is being developed by Cimco who is a mastercam reseller. They have all they need in order to continue developing their c-hook.
Best output for a Röders is pure line segments. Then the spline interpolation works best. Don't use any smoothing.
Röders
I would use a finishing tolerance between 0.01 - 0.0005mm. depending on part size and needed surface finish and accuracy.
Let's see if this post clears the sensorship
Some CAD/CAM maintenance percentage:
Mastercam 10%
Powermill 12%
Edgecam 16%
SolidWorks 25%
Siemens NX 22%
These numbers can of course vary from country to country.
Interesting.
PowerMill forum
Delcam has released service packs for Powermill 2011 even after releasing 2012. Powermill 2011 reached service pack 11 in its lifecycle.
I don't think Powermill has more bugs than Mastercam, I just think Delcam puts more pride in fixing problems.
Just remember that these 140 developers are split over many softwares. Powermill, powershape, partmaker, featurecam + more.
I'm quite sure the powermill dev team is <50.
Please check page 12.

Original HST toolpaths are from NC Graphics.
Cimco's HSM Performance Pack is also from NC Graphics.
With a good post from In-House or Cimco with support for TWP and TCPC you don't have to program from centre of rotation. Just put your work piece zero point on the machine in the same place as your mcam zero point and you're ready to cut.
I tested a 3X Volumill program on a Matsuura MX-520 with iZ-1/30 ( Ai Contour Control-II ) Programmed feedrate was 7200mm./min. and Highfeed 20000mm./min.
Mastercam backplot time 4m36s
G131 R1 time 7m 5s
G130 ( no highspeed active ) time 5m32s
If you setup your fanuc nc-format with G68.2 (TWP) for indexing and G43.5 (TCPC type 2) for simultaneous, you could actually use the exact same nc-program on both AC and BC table kinematics.
More accurate yes, faster no.
Because of the more accurate path control the machining time will in most cases also be longer because the controller slows down the feedrate to stay on the correct path.
I've done some test on new Matsuura's with 30i/31i and the fastest running time was without highspeed active. But this was very unaccurate so it could only be used for roughing.
CNC sure isn't very informative on this matter.
What about all the user who already upgraded to X6. Should they go back to X5?
An official statement from CNC could be nice.
If you checked Omoe's links you would see it was a CNC download and not some pirate site.
