people,
i am running a citizen m32 and trying to mill a simple post/boss on a part and the darn thing is eggshaped. a half thou wouldn't bother me, but i am looking at .003" i have reprogrammed this thing 6 ways to sunday and nothing has worked. my tools are on center, new endmills, different speeds and feeds. any ideas?
What diameter are you trying to mill? I ask so I can understand what percentage of the total dimension that .003" represents. Which axiis are you using to make the feature?
Hello
Sounds like your Y to Z axis ratio is out. If not code specific this could be caused by you programming Y axis co-ordinates in radiall as opposed to diametrical. Citizen M32 series 2 used radiall values on Y1 axis whilst series 3 and newer the user can select via MC Strct page
If this is not the case then then if you let me know code and size required i can hopefully help
it is milling in the yz plane. it is a .125Ø post in 303ss material.
If you are using Z1 it could be that the Guide Bushing needs tweeked...
If the feature seems good in Y but smaller in Z then GB too tight.
If the feature seems good in Z but large in Y the GB is too loose.
When everything is right, they still do not produce perfect round post or holes.
HTH, Good Luck!
Sometimes the radius in the program might need to be tweeked, are you using G12.1, or are you selecting the proper plane select (G19 Y-Z plane).

If you could post the code we could rule that out.
ALSO the "R" and "P" values you are using.
