This paper presents models, computational primitives and procedures, describing the behaviour of machines, distortions of parts, assembles and movements; where the state of such machines may be launched to CAD browsers through interfaces, constituting a whole system named by us virtual multiaxis machine (VMM). Although similar concepts appeared more than 13 years ago for aiding calibrations, their modelling was so difficult to understand for most people in the field of metrology, design and manufacturing. The focus of this research is to look for easier alternatives than conventional ones, for calibrating coordinate measuring machines (CMMs) or similar instruments, and for mapping their errors. The VMM system allows verifying measures on scales, intermediate states of assembles among bodies, or final states in probes, without ambiguity. Linked to CAD, the system help us to use the VMM as an equivalent laboratory, where scales, guide-ways, and assembles, may be changed and verified. The VMM may also be used for teaching, for doing geometrical meaning to parameters of calibration, and for judging cases of controversy in calibrations.
