The Influence of Selected Parameters on Evaluation of the Geometrical Shape Deviation – Cylindricity in 3D Measuring Machine Workspace

Abstract

Each part as a final product and its surface is composed of various geometric elements, although at first glance seem as smooth and shiny. During the manufacturing process, there is a number of influences (e.g. selected manufacturing technology, production process, human factors, the strategy of measurement, scanning speed, shape of the measurement contact tip, temperature, or the surface tension and the like), which hinder the production of component with ideally shaped elements. From the economic and design point of view (in accordance with determined GPS standards), there is necessary fast and accurate analyze and evaluate these elements. Presented article deals with the influence of scanning speed and measuring strategy for assessment of shape deviations.

Identification and Analysis of Defect in Forging Tools by Non-Destructive Detection Method

“…Detection of the nature or orientation of the defect is based on the directivity of ultrasonic transmission. The reflective property of these components, and thus the shape of the echo, depends on the nature and size of the defect [6,9].…”

Skiving as Substitution of Tooth Grinding

“…In picture 1 -Shape of tools -there is comparison of tool tooth for soft hobbing and skiving. [3,5,6] …”

The Influence of the Size Styles for the Touching Probe for the Roundness of the Deviation

“…The reference circle is defined by ISO 4291: 1995 as the circle bound to the circularity profile in accordance with the specific properties of the deviations of the circularity as well as the circular parameters given [4,5].…”

“…Standard ISO 6318 provides next four assembling elements: Least Square Circle (LSC), Minimal Circumscribed Circle (MCC), Maximal Inscribed Circle (MIC), and Minimum Zone Circles (MZC)". [5,6] The circularity variations were measured in the plane of the cut z = 8 mm from the upper plane of the measured pcomponent ø 37.50 mm. Evaluation using the LSC reference circle.…”
