Summary of Roughness ParametersCommonly UsedArithmetical mean deviation of the profile Ra (ISO 4287, DIN 4768)

The arithmetical mean deviation Ra is the mean value of the absolute valueof the profile departure y within the reference length l.

Max. profile valley depth Rmax (DIN 4768)

Among the existing single roughness depths Zi, the max. profile valley depthRmax counts for the most significant within the total measuring length lm.

According to ISO 4288 and DIN 4287 - Part 1, this parameter is also specified as Ry max.

Mean roughness depth Rz DIN (DIN 4768)

The mean roughness depth Rz is the arithmetical mean of the single rough-ness depths of successive sampling lengths le.

According to ISO 4287 and DIN 4762, the parameter Rz DIN is also specified as Ry5.

Because Rz is named differently in DIN 4768 and ISO 4287, this para mater isalso specified as Rz DIN or Rz ISO.

When the parameter Rz is measured according to DIN, it is generally admit-ted that the extreme value ISO is also matched providing thatRz ISO is not exceeding Rz DIN .

Application of Roughness Comparison SpecimensThese specimens for testing the surface finish quality have long proven theirvalue in practical use.

They serve for touch and/or sight comparisons with the surface of the work-pieces that are manufactured using the same method. Condition is thatmaterials have to be comparable.

The comparison of the roughness of theworkpiece surface is not quantitativelyexpressed. The extent to which the surfacesof both the specimen and the workpiece arematched is appreciated subjectively only.

Sight comparison requires optimum lightsource angle. For small surfaces, the use ofa magnifying glass with up to 8x magnifica-tion is recommended.

Touch comparison is made using the fingernail or a small copper piece like a coin, forinstance.

Pocket Surf® Gage The Pocket Surf gage is a pocket-sized, economically priced, completelyportable instrument for performing traceable surface roughness measurementson a wide variety of surfaces (including small inside diameters). The PocketSurf gage is solidly built with a durable cast aluminum housing to provide years of accurate, reliable surface finish gaging. Designed for use in a shopenvironment or in the laboratory, the Pocket Surf works on both horizontal andvertical surfaces. It can be used at any angle and can even be held upside-down. For even greater versatility, it operates in four probe positions – closedor with the probe at 90˚, 180˚ or 270˚. Use the Pocket Surf for flat surfaces ofboth, inside and outside diameters, as well as many difficult-to-gage surfaces.

CapabilitiesThe Pocket Surf can measure any one of four switch-selectable parameters.

• Ra Average Roughness• Ry Maximum Roughness Depth• Rmax Maximum Roughness Depth (DIN)• Rz Mean Roughness Depth (DIN), also called Rtm

Rmax and Ry are convenient “burr” and “scratch” control parameters and valu-able additions to Ra and Rz. The gage’s digital display is conveniently locatedon the top of the unit for optimum visibility. The easy-to-read LCD readoutpresents the measured roughness value, in microinches or micrometers, withinhalf a second after the surface is traversed. Out-of-range (high or low) and“battery low” signals are also displayed.

Selectable Traverse Length 1, 3, or 5 cutoffs of .030" (0.8 mm) each, permit checking surface lands as shortas .075" (1.9 mm). The start switch is centrally located for optimum stability.

Pocket Surf Measurement ParametersRa — Roughness AverageThe arithmetic average height of roughness irregularities measured from a mean line within the evaluation length (L).

Rmax — Maximum Roughness Depth (per DIN)The largest of the 5 maximum peak-to-valley roughness depths in 5 succes-sive sampling lengths. In the illustration below, Rmax (DIN) = Ry 4

Rz — Mean Roughness Depth (per DIN), also known as Rtm

The mean of 5 maximum peak-to-valley roughness depths in 5 successivesampling lengths

Note: To fully meet the requirements of DIN 4768 for Rmax and Rz, probes having a stylus radius of .0002" (5 µm) are available.

Ry — Maximum Roughness DepthFor the evaluation length equaling one cutoff, it is the vertical distance betweenthe highest peak and the deepest valley within the sampling length. For theevaluation length equaling 3 cutoffs, it is the largest of the 3 maximum peak-to-valley roughness depths in 3 successive sampling lengths.

Probe VarietyA variety of probes are easily interchangeable, increasing the gage’s capabilityfor a wide range of applications, such as flats, O.D.s, I.D.s (including smallbores), sharp edges, inside “O” ring grooves, short lands and shoulders.

Built-in Digital OutputWith built-in digital output, the Pocket Surf gage is designed for SPC applications and is compatible with most major SQC datacollection systems. Although it provides powerful flexibility for a portable sur-face finish gage, the Pocket Surf gage uses a regular, consumer-type, 9 voltalkaline battery. Data can be output through an RS-232 port and printed on aBrown & Sharpe SPC printer.

Portable Vee FixtureThe Portable Vee Fixture simplifies themeasurement of small outside diameterparts up to 1" (25mm). This optionalaccessory comes complete with a PS-145 setting pin.
