The Roland PNC line made it's debut in 1986 with the PNC-3000 "CAMM-3" milling machine. It was followed in 1987 by the first "CAMM-2" PNC-2000 engraving machine, and in 1988 with the first "CAMM-1" PNC-1000 cutting machine.
The numerical model numbers roughly reflect the number of axis dimensions controlled - 3D has 3, engraving has 2, and cutting has one. The 3xx models are milling machines, and the 9xx models are cutters. Just to make things interesting, the PNC-2500/R/G/H/HG models are also a "CAMM-3" machine even though it is in the 2xxx series.
The CM, CX, and GX cutter series still refer to the "CAMM-1" nomenclature, but the Engravers (CAMM-2) and Milling Machines (CAMM-3) have dropped this title since the introduction of the EGX and MDX series respectively. The "PC" inkjet printer series is referred to as "ColorCAMM". The PNC-5000 is a color printer and is included as a ColorCAMM machine.
