ROUNDTEST/ROUNDTEST EXTREME ...The best in its class roundness/cylindricity measuringsystem for the ultimate in accuracy and ease-of-use.The RA-2100series is available in two types: the RA-2100AS/AH/DS/DH models, and the RA-2100S/H CNC machines thatfeature detector orientation control (see pages 3 and 4 fordetails).Eachmodel incorporates an automaticturntable to allow workpiece centering/levelingto be performed simply and accurately. This is a vital,but usually time consuming element of workpiece setupfor roundness/cylindricity measurements (see pages4 and 6 for details).2

Manyoptional accessories, such asstyli, chucks and calibration standards,are available to make it easy to measure awide variety of workpieces (see pages10 and 11 for details).Detector orientation control in 1°increments (unique to RA-2100CNC)The ROUNDPAK dataanalysis software allows a wide rangeof analyses to be performed easily (seepages 8 and 9 for details).Surface roughnessmeasurement (Optional)RA-2100CNC RA-2100AS/AH/DS/DHPhoto: RA-2100H CNC3

ROUNDTEST EXTREME RA-2100S/H CNCCNC Roundness/Cylindricity Measuring Systems...Greatly Enhancing Productivity and EfficiencyTurntable features high accuracy and ease-of-useHigh turntable rotational accuracy, in both the radial (0.02 + 3.8H/10000µm) and axial (0.02 + 3.8X/10000 µm) directions, allows high accuracyflatness testing to be performed in addition to roundness and cylindricitymeasurements. The automatic alignment feature of the turntable enhancesproductivity by eliminating time-consuming workpiece centering and levelingoperations.Detector orientation control in 1° increments tosupport CNC automatic measurementDetector holder arm orientation (vertical/horizontal) and detector rotation(within a range between 0 to 270°, in increments of 1°) are automaticallycontrolled to provide automatic and continuous measurement of OD, ID, andtop and bottom surfaces. Also, the powerful off-line teaching function allowsa part program to be created with ease.Mitutoyo linear scales ensure high accuracy CNCmeasurementsMitutoyo linear scales are used in the X/Z drive unit to guarantee the highprecision positioning so vital for automatic CNC operation.External dimensions RA-2100S/H CNCUnit:mm (inch)475 (18.70 )405 (15.94")¿235 (9.25")667 (26.26 )Max.940 (37.01 )RA-2100S CNC:900 (35.43")RA-2100H CNC:1100 (43.31")380 (14.96 ) 420 (16.54 )221 (8.70 )Detector rotationmechanism(0 to 270˚, increments of 1˚)AAT (Automatic Adjustment Table): Automatic workpiece centering/levelingTurntable axisleTurn tabBAInitial misalignment of axesWorkpieceHolder-arm orientation switching(vertical position - horizontal position)leTu rn tabTurntable axisWorkpieceInitial misalignment ofcenters at turntable surfacePreliminary measurementPreliminary measurement of twocross-sections A and B .Centering/leveling completePreliminary measurement isfollowed by automatic centeringand leveling4

Roundness/cylindricity measurement/analysis softwareROUNDPAK ®Software to simply control preliminary setup, measurement, analysis, andresult output.Preliminary setupCentering/leveling the workpieceMitutoyo’s unique AAT functionality (which measures initialmisalignment and automatically centers and levels the workpiece)and DAT functionality (which measures and displays the amountof adjustment needed to center and level the workpiece) havebeen highly commended by customers as superb solutions to thebothersome preliminary setup work of centering/leveling.Simulating part programsThe part program (automatic measurement procedure) can besimulated in 3D form on screen displays generated by the designdata generation function.3D simulation screens (work-viewwindows) can be generated afterentering CAD data (in IGES, DXFform) and text data.MeasurementMeasurement modeTwo modes are available for selective use: ‘Simple mode’ to simplymeasure and ‘Part program mode’ for measurement and analysis ofmultiple items.Convenient measuring functions(1) Edge detection functionA coordinate system can be set up for aworkpiece. This allowsmeasurements to berepeated easily onidentical workpieces.(2) Continuous OD/ID measuringfunctionBoth the OD and ID of a workpiece can bemeasured in succession without the need forchanging the traverse direction of the stylus.(3) Partial arc measuring functionThis enables measurements to be performedon a workpiece having a projected section orincomplete circumference.8

Analysis, results outputA variety of parameters and analysis functionsA variety of parameters, not only for roundness and cylindricity, but also for flatnessand parallelism, can be handled. Also included are functions for design data best-fitanalysis, harmonic analysis and circumferential peak-bottom detection, etc.*1: For further information about parameters, refer to the ROUNDPAK catalog.Measurement data utilization(1) Re-calculation functionIt is possible to re-calculate ananalysis using measurement datapreviously obtained but usingchanged measurement conditions(filter-cutoff values, etc.), or differentanalysis parameters.Result outputResult output is possible in the customer’s original format accordingto the layout prescribed for the location, size, etc., of the analysisresults including graphics and drawings. The original layout, ifsaved, allows automatic operation from measurement to calculation(automatic saving, results display, and printing) just by pressing themeasurement start button.(2) Data deletion functionThis function allows calculation/analysis to be performed with only theremaining data after deleting unnecessary point data (from a notchedsection, or from anarea outside the targetarea on the workpiece)from that obtained bymeasurement.Graphical display of resultsResults of analyses, such as for cylindricity or coaxiality, can bevisually represented by a 3D graphical display. This 3D graphic canbe pasted into a report.Normal displayWire-frame displaySurface map displayShading display9
