Abstract
A hexapod CMM or hexapod-like CMM has a base structure and a movable structure connected to each other by at least three telescopically extendable legs via spherical joints. Each of the telescopically extendable legs comprises a linear first member and a linear second member having countersliding surfaces and are designed in such a way that allows a relative, linear movement of the first linear member and the second linear member. Further each of the telescopically extendable legs has an air cushioning mechanism, which comprises at least one air supply system connected to at least one source of compressed air and having at least one air escape. The air escape is arranged in such a way that compressed air escaping the air escape flows into a gap between the countersliding surfaces of the at least two linear members of the leg cushioning the two linear members against each other.
