PREFACE

250
Optimization of surface microgeometry is proved to be advisable for provision of its specific functional properties; conditions for the optimization to be fulfilled are defined. Using concrete examples, microgeometry optimization on the base of parametric criteria of its assessment and control is shown to be practically impossible because of a wide range of parameters necessary for a processed surface description to be applied in serial production. A method is proposed for deduction of microgeometry being optimal (practically – the best of all feasible) for a specified property of a given workpiece surface. Technological ways for realization of the microgeometry in manufacturing process and fast, reliable, and low-cost control of the workpiece surface are developed. Computer programs using profiles and microtopographic data for control over a surface microgeometry on the base of graphic criteria are created. Examples of practical applications of the methods and programs are presented to demonstrate effectiveness of the proposed approach.
