Abstract Rotationally symmetric components (such as gears and axels) are ubiquitous to modern devices, their precision manufacture is necessary keep costs time down, well reduce waste possibly hazardous component failure. The manufacturing errors, which affect the shape in rotation axis, grouped together into common term “runout". Here we present a potential updated standard for characterising runout of rotationally machined parts three-dimensions, evaluated using virtual instrumentation,...
Abstract A new method for performance validation of surface texture parameter calculation software is introduced, focussing on field parameters. Surface height functions are defined mathematically, either using Fourier series or polynomials, and then input into the definitions to obtain mathematical values. user-adjustable parametric that correspond each parameter, enabling users create a variety surfaces assess their whilst still retaining traceability. This expanded include complex...
A new method for performance validation of surface texture parameter calculation software is introduced, focussing on functional parameters. Material ratio curves are defined algebraically and used to calculate parameters mathematically. Discrete datasets created from the material input into three third-party packages. Comparisons made between software-obtained values mathematical values, identifying significant differences them. Work carried out highlight inaccuracies introduced by sampling...
This paper reports on an in-depth analysis of ISO 5436 part 2 type F2 reference software for the calculation profile surface texture parameters that has been performed input, implementation and output results developed by National Physical Laboratory (NPL), Institute Standards Technology (NIST) Physikalisch-Technische Bundesanstalt (PTB).Surface have calculated a selection seventeen test data files obtained from F1 sets offer NPL NIST.The parameter show some disagreements between methods...
Abstract A novel method for the validation of surface texture filtration software is introduced. Mathematically traceable reference pairs linear Gaussian are developed, utilising Fourier series definitions in conjunction with frequency dependent transmission characteristic filter.

The performance of measurement or manufacturing systems in high-precision applications is dependent upon the dynamics system, as vibration can be a significant contributor to uncertainty and process variability. Technologies making use accelerometers laser vibrometers are available rapidly measure structural dynamic data but software infrastructure yet an open source standardised format allow rapid inter-platform use. In this paper, we present novel condition monitoring which uses...
A framework for the validation of surface texture parameter calculation software is proposed. The utilises mathematically defined surfaces and calculated values to produce a reference against which third-party can be compared; in principle, free from approximations that are intrinsic when applying numerical methods algorithms discrete data order realise continuous definitions. This paper provides proof-of-concept new using simple two-term cosine surface. required steps enable meaningful...
