quick question

[ghostlx]

in mastercam when i select a machine (mill) and i get my fly out box for machine def.

i have a question about what certin things mean

example : machine 10 says c:\mcamx\cnc_machine\mill 3 axis hmc.mmd
if i am understanding what i have read this ih a horazontal 3 axis mill

example 2 machine 9 says c:\mcamx\cnc machine\3-axis mill hmc-mm.mmd
here is the question what does the extra mm stand for?

these are the original posts for mastercam x mr2 and i am just looking to improve myself
thanks
