|Title:||INTERNAL DIMENSION DETECTION USING CONTACT DIRECTION SENSITIVE PROBE|
A robotic coordinate measurement machine (CMM) having a contact direction sensitive (CDS) probe is usable to detect internal dimensions for an object of interest. A robot arm may contact a surface with the CDS probe which may then detect a magnitude and direction of the resulting reaction force. The robotic CMM may monitor the magnitude and/or direction of the reaction force while the CDS probe is being slide across a surface to determine dimensions for the surface. Changes in the reaction force sensed by the CDS probe may be used to identify contact with other surfaces of contours in the surface the CDS probe is being slid across. A path of the CDS probe may be altered based on the contact with other surfaces or the contours.
