Analysis of Eccentricity in the Ball Bar Measurement

Journal of Mechanical Science and Technology, 2010
The ball bar is widely used in machine tool measurement because it is convenient and cost effective. Eccentricity exists due to machine errors and installation errors during a ball bar test, and the coordinate transformation method is used to remove eccentricity.

Effects of Lifter Bars on the Ball Motion and Aluminum Foil Milling in Tumbler Ball Mill

Materials Letters, 2002
Effects of lifter bars on the ball motion during ball milling and characteristics of aluminum flake powders prepared by the ball milling of aluminum foil scraps were studied. When rotation speed of milling jar without lifter bar is below 75% of critical revolutions per minute (rpm), balls slide in the jar.

Properties of Free-Standing Ball Bar Systems

Precision Engineering, 1993
Abstract This article offers recommendations to coordinate-measuring machine (CMM) buyers, sellers, and users on the design of free-standing ball bar systems used to evaluate the volumetric performance of CMMs according to the ANSI/ASME B89.1.12M standard. These systems are more widely used today than earlier methods such as magnetic ball bars.

Robot Accuracy Evaluation Using a Ball-Bar Link System

Robotica, 2011
SUMMARYRelatively large errors can exist in industrial robots as a result of mismatch between the controller model and the corresponding physical model. The paper outlines a novel approach for accuracy assessment and adjustment of multiaxis industrial robots through a low-cost ball-bar link system.

An extensible ball bar for evaluation of robots' positioning performance

Journal of Robotic Systems, 1987
AbstractThis article describes the development of a one‐dimensional extensible ball bar designed to measure the positioning accuracy and repeatability of industrial robots. The ball bar has a linear travel of 5 cm (2 in) that is monitored by a built‐in electronic transducer having a resolution of 2.5 μm (0.0001 in).
