The effect of the point sampling to the result of coordinate measuring of free-form surface
(Національний технічний університет "Харківський політехнічний інститут", 2022) Varga, B.; Mikó, Balázs
The coordinate measuring technique appropriates to measure dimensional and geometric properties of a machine part. The result of the measuring is effected by several parameters, like the measuring method, the point sampling technique, and the mathematical processing of the measured coordinates. The current article investigates the effect of the point sampling methods in case of a freeform surface. Two methods are compared: the uniform matrix method, and the Halton-Zaremba quasirandom method. The number of measured points is investigated also. The free-form test surface was produced by ball-end milling, and the radius, the cylindricity and the surface profile error were assessed.
