obtained The includes a third step of determining the point group of the combination of the focus evaluation value and the moving distance, and a fourth step of applying the reference curve to the point group to determine the pitch on the basis of the position-fitting of the reference curve....
Noncontact Method for Measuring Pitch of Gear Teeth and Screw A method for measuring the pitch in a noncontact way in a short time with high precision by using a simple device. The method includes a first step of moving an object () having shape-of-interest portions () of generally the ...

The pitch diameter of a screw thread may be measured very accurately by means of some form of dial caliper or micrometer and three wires of equal diameter. This method is extensively used in checking the accuracy of threaded plug gages and other precision screw threads. Two of the wires are...

The principle of "indirect measuring" on CNC-controlled machines is based on the assumption that the leadscrew pitch is constant at every point within the traversing range. This means that the actual position of the axis can be derived from the position of the drive spindle (ideal situation)....
This means that the actual position of the axis can be derived from the position of the drive spindle (ideal situation). Manufacturing tolerances in ball screw production, however, result in large dimensional deviations to a lesser or greater extent (referred to as leadscrew pitch errors). ...
broad spectrum of screw and thread measurements. Whether you are working with fine-pitched screws or larger, coarser ones, this tool has got you covered. The clear markings and easy-to-read numbers facilitate quick and accurate identification of the correct pitch, making it an essential ...
