Abstract: A technique for compensating the errors of coordinate measuring machines (CMMs) with low stiffness is proposed. Some additional
items related with the force deformation are introduced to the
error compensation equations. The research was carried on a
moving column horizontal arm CMM. Experimental results show that
both the effects of systematic components of error motions and
force deformations are greatly reduced, which shows the
effectiveness of proposed technique.
