A method and apparatus for measuring a part with a contact probe mounted on a coordinate positioning machine. The method includes measuring a plurality of points on the part when both the part and contact probe are moving continuously between different positions within the coordinate positioning machine. The probe moves, relative to the part, along a scan path such that substantially coincident points that are closely located together along a curve or surface being measured are measured at relatively far apart positions in the machine and at relatively far apart positions along the scan path.

A method of determining a radius of a cutting end of a tool for a turning machine using a touch probe is provided. One of the cutting end and the touch probe is movable relative to a reference frame having a first axis and a second axis and having a reference point trackable in the reference frame. The method comprises establishing a first contact point and recording a first coordinate of the reference point on the first axis; establishing a second contact point and recording a second coordinate of the reference point on the second axis; establishing a third contact point and recording a third coordinate of the reference point on the first axis and a fourth coordinate of the reference point on the second axis upon contact; and determining a radius of the cutting end based on the first, second, third and fourth coordinates.

Described herein are systems and techniques for estimating a shape of a structure undergoing dynamic stress. In some embodiments, a method includes: for each of a plurality of nodes distributed along a length of the structure, obtaining, from an accelerometer located at the node, a tilt angle corresponding to an angle between a local axis of the structure and a direction of gravity; calculating, by a microcontroller, vertical displacements between adjacent pairs of the plurality of nodes using the respective tilt angles obtained for the adjacent pairs; and calculating, by the microcontroller, a depth of each of the plurality of nodes relative to a proximal end of the structure by adding the vertical displacements calculated for adjacent pairs of the plurality of nodes between the node and the proximal end of the structure.
