5 Summary of Roughness Parameters Commonly Used Arithmetical mean deviation of the profile Ra (ISO 4287, DIN 4768) The arithmetical mean deviation Ra is the mean value of the absolute value of 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 depth Rmax counts for the most significant within the total measuring length lm. According to ISO 4288 and DIN 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 roughness 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 is also specified as Rz DIN or Rz ISO. When the parameter Rz is measured according to DIN, it is generally admitted that the extreme value ISO is also matched providing that Rz ISO is not exceeding Rz DIN. Application of Roughness Comparison Specimens These specimens for testing the surface finish quality have long proven their value in practical use. They serve for touch and/or sight comparisons with the surface of the workpieces that are manufactured using the same method. Condition is that materials have to be comparable. The comparison of the roughness of the workpiece surface is not quantitatively expressed. The extent to which the surfaces of both the specimen and the workpiece are matched is appreciated subjectively only. Sight comparison requires optimum light source angle. For small surfaces, the use of a magnifying glass with up to 8x magnification is recommended. Touch comparison is made using the finger nail or a small copper piece like a coin, for instance. l t 1 Z 2 Z 3 Z R max 4 Z 5 Z y m R a 0 x Ie 5 x l e = lm l J-4 Pre-course Post-course

The Pocket Surf gage is solidly built with a durable cast aluminum housing to provide years of accurate, reliable surface finish gaging. Designed for use in a shop environment or in the laboratory, the Pocket Surf works on both horizontal and vertical surfaces. It can be used at any angle and can even be held upsidedown. For even greater versatility, it operates in four probe positions closed or with the probe at 90, 180 or 270. Use the Pocket Surf for flat surfaces of both, inside and outside diameters, as well as many difficult-to-gage surfaces. Capabilities The 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 valuable additions to Ra and Rz. The gage s digital display is conveniently located on the top of the unit for optimum visibility. The easy-to-read LCD readout presents the measured roughness value, in microinches or micrometers, within half 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 short as.075" (1.9 mm). The start switch is centrally located for optimum stability. 4 possible measuring positions of the stylus 3000 h Durable cast aluminum housing F to 113 F - 4 F to 149 F closed Basic instrument without probe: 5.5 x 3 x 1 in Basic instr. without probe: 435 g Plastic case Declaration of conformity.

11 Pocket Surf Measurement Parameters Ra Roughness Average The 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 successive 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 successive sampling 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 Depth For the evaluation length equaling one cutoff, it is the vertical distance between the highest peak and the deepest valley within the sampling length. For the evaluation length equaling 3 cutoffs, it is the largest of the 3 maximum peak-to-valley roughness depths in 3 successive sampling lengths.

13 Battery Operated Probe Variety A variety of probes are easily interchangeable, increasing the gage s capability for a wide range of applications, such as flats, O.D.s, I.D.s (including small bores), sharp edges, inside O ring grooves, short lands and shoulders. Built-in Digital Output With built-in digital output, the Pocket Surf gage is designed for SPC applications and is compatible with most major SQC data collection systems. Although it provides powerful flexibility for a portable surface finish gage, the Pocket Surf gage uses a regular, consumer-type, 9 volt alkaline battery. Data can be output through an RS-232 port and printed on a Brown & Sharpe SPC printer. Built-in Digital Output Portable Vee Fixture The Portable Vee Fixture simplifies the measurement of small outside diameter parts up to 1" (25mm). This optional accessory comes complete with a PS-145 setting pin. Height Stand Compact and convenient, an optional height stand with bracket is available as a holding fixture for the Pocket Surf gage. This optional accessory holds the Pocket Surf both horizontally and vertically, making it easy to take measurements on a surface plate or on any suitable, flat working surface Swivel Fixture for Mounting on Height Gage DP. For added flexibility, the Swivel Fixture allows the Pocket Surf to be moved and locked into position at any angle. Complete with a T-Bar attachment fixture, the Swivel Fixture will work with most standard column gages and height stands. Height Stand with Swivel Fixture For maximum convenience and flexibility, purchase the Height Stand together with the Swivel Fixture. This complete set will give you a fully functional holding fixture for your Pocket Surf gage, allowing you to position the tool horizontally, vertically, or at any angle in between. J
