Measurement and Analysis of Brushing Tool Performance Characteristics, Part 1: Stiffness Response

In the first part of this paper, an experimental system is described which was developed and used for measuring compliant tool performance characteristics. Elementary mechanics considerations and signal-response characteristics of the experimental apparatus for orthogonal brushing are briefly outlined and discussed. The fundamental nature of wire brush stiffness properties and kinetic friction coefficients for orthogonal brush-workpart contact are determined for a range of rotational speeds, and the results are compared to those obtained on the basis of a recently developed (quasi-static) theoretical solution. Discussion is provided concerning three-dimensional filamentary forces which are developed within the contact zone during brush rotation.
