  • Patent number: 5657549
    Abstract: A method for improving accuracy of dimensional measurements of a touch trigger probe. The method includes moving a touch trigger probe in an approach direction toward an object, contacting a contact point on the object with a portion of the touch trigger probe, generating a trigger signal corresponding to coordinates of the contact point after the touch trigger probe travels a pretraveled distance, and adjusting the coordinates to compensate for the pretravel. The adjusting step compensates for bending of the touch trigger probe and the bending is calculated as a function of trigger force derived from contact forces of a kinematic seating arrangement of the touch trigger probe. The method is effective in compensating for variations in trigger force due to the approach direction commonly referred to as lobing. The method is applicable to straight and non-straight touch trigger probes.
