Abstract

Standards are available only for the evaluation of simple surfaces like planes and cylinders to evaluate flatness and circularity. For many other surfaces like spheres and elliptical surfaces, methods have been developed by the author. In this paper, it is proposed to develop a method for the evaluation of simple torus surfaces like ring doughnut for which there are no standards or methods. The torus surface (torus of revolution) has application in chemical and enzymatic modifications of plant proteins. The CMM or flexible CMM like ROMER is suitable for measuring the surface data. Data measurement at equally spaced locations on the surface is preferred for better results. MATLAB has been used to simulate the measured data and test the developed mathematical model for its evaluation and a new term toricity is used to define the error.

Keywords
