One of the parameters most commonly used in the control of workpieces complex form is
roundness. Increasing requirements to the workpieces form accuracy determines the …

Today, the quantitative evaluation of the quality of circular or cylindrical workpieces is
becoming increasingly important for the relevant industrial production sectors. Although …

Contact between two highly loaded flat surfaces is examined. In these experiments, a
polished, hard metal surface was pressed against a rough aluminium alloy surface. The goal …

The production of two-wheeled rolling stock represents, at first glance, a simple assembly
process that significantly affects the overall functionality and safety of the vehicle. This is due …

A new metering and data-processing method for the centerless roundness measuring, using
corrective adjustment, is scientifically developed. In this paper, a mathematical model based …

The sphericity error is one of the most important tolerances to evaluate the dimensional
accuracy of bearing balls. A continuous dynamic measurement system based on an …

This study proposes a high speed and accurate evaluation method for minimum zone
roundness (MZR) using an optimal solution guidance algorithm (OSGA). The least-square …

Spherical surfaces are utilized widely in precision bearing, MEMS and parts of precision
engineering. Constantly growing needs in the high motion performance of spherical parts …

The article describes a method for diagnosing the accuracy of the vehicle scale without
using standard weights. The novel method defines the possibility to estimate whether the …

Progress in the advanced branches of technology has caused the need to manufacture parts
of highly complex shapes that are often found through experimenting and only later is …
