Abstract: The paper considers a point algorithm for specifying a cylinder, with a guiding axis in the form of a circular sine wave and a generatrix in the form of a circle, based on the MPS (mobile simplex method). The paper uses point equations of a circle and a circular sinusoid, obtained on the basis of graphical algorithms for constructing these curves by methods of BN-calculus (Balyuba-Naydysh point calculus). A computational algorithm for constructing a circular sinusoid with an axis in the form of a circle using polar parametrization of the plane is presented. An algorithm for obtaining a point equation of a circular cylinder with a sinusoidal axis based on the MSM is considered. Examples of constructing a circular sine wave in the plane of the general position and a circular cylinder with a sine axis at different values of the coefficient specifying the number of periods using the Maple software package are given. Such a surface can be used when specifying shells of various technical forms.

Keywords: point algorithm, evolvent, ellipse, BN-calculus, mobile simplex method (MSM).
