Data for evaluating circularity error can be obtained from coordinate measuring machines or
form measuring instruments. In this article, appropriate methods based on computational …

Evaluation of form error is a critical aspect of many manufacturing processes. Machines such
as the coordinate measuring machine (CMM) often employ the technique of the least …

A common problem of quality control and inspection of circular parts is the measurement of
their roundness. Recently, the coordinate measuring machines (CMMs) have been used to …

The coordinate measuring machines (CMMs) have proven to be reliable, flexible and very
much suitable for determining the acceptability of manufactured parts. In this paper …

In this paper, we propose anew procedure for measuring roundness errors by computong
apaor of concentric corcles with the minimum tsdial separation for assessing the srrors by …

Estimating any geometric tolerance requires to sample a cloud of points on the feature to
check, and then to fit an ideal substitute geometry respect to which to evaluate errors …

This paper presents a novel algorithm for evaluating roundness from discrete coordinate
data measured by a coordinate measuring machine (CMM). The main feature of this …

In this paper the authors present an original methodology aiming at the automation of the
geometric inspection, starting from a high-density acquired surface. The concept of intrinsic …

The evaluation of roundness based on the maximum inscribed circle method is an important
method suitable for the circle with the maximum material condition like an internal bore. The …

An iterative neighborhood search approach (INSA) was proposed to precisely evaluate the
circularity error under minimum zone conditions without directly solving nonlinear equations …
