Abstract
A co-ordinate measuring machine (1) comprising a machine bed (2) provided with guides along a first axis, and a mobile unit (4) comprising at least one main carriage (5) mobile along the guides (16a, 16b, 16c); the machine bed (2) comprises a closed perimetral metal frame (15) provided with guides (16a, 16b, 16c) and a worktable (17) housed within the frame (15); the worktable (17) and the frame (15) are constrained to one another by constraint means (35) that uncouple the deformations thereof.
Claims14
A co-ordinate measuring machine comprising:
- a machine bed defining guide means along a first axis;
- and
- a mobile unit comprising at least one main carriage mobile along said guide means, wherein said machine bed includes a closed perimetral frame provided with said guide means and a worktable at least partially housed within said frame, said worktable and said frame being constrained to one another by constraint means that uncouple deformations thereof, wherein;
- said constraint means are statically determined;
- and
- said constraint means comprise a first constraint that eliminates three degrees of freedom, a second constraint that eliminates two degrees of freedom, and a third constraint that eliminates one degree of freedom.
