Back to the envelope system with morphological operations for the evaluation of surfaces

“…2 are identical to the results of Weingraber and others [1][2][3] after the tracing of the profile of a surface with different tip radii representing the envelope system. Parallel to the considerations of Weingraber and others the classification of the geometrical properties based on wavelength has been developed (see Fig.…”

“…In the envelope system investigated by Weingraber and others [1][2][3] the discussion of the surface properties were based on the dilatation only (see Fig. 2).…”

“…Over 50 years ago Weingraber [1][2][3] and others recognized the deficiency of the mean line system for the assessment of surface properties. They tried to implement the envelope system as a more practical approach but failed due to the dependability on mechanical probes of different diameters, the lack of computational power and the availability of software.…”

Calibration and verification of areal surface texture measuring instruments

“…The history of surface texture measurement can be found elsewhere [11,71,118,145,189,193] and this section will highlight some of the important developments, specifically in calibration and performance verification. One of the earliest attempts at controlling surface texture was made in the USA by a company that mounted samples of textures produced by different methods in cases [157] which were given to the machinist, who was expected to obtain a texture on his or her workpiece as near to that specified as possible.…”

“…Wenn nichts anderes angegeben ist, bezieht sich der Wert für Rz auf fünf Einzelmessstrecken. Diese Einzelmessstrecken bilden die Messstrecke und zusammen mit einem Vor-und einem Nachlauf die Taststrecke [17]. Figure 10: Envelope System of v. Weingraber [17].…”
