Surface roughness- a measurement  of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If the deviations are large, the surface is rough, if they are small, the surface is smooth.

PRECISION DEVICES, INC. MicroAnalyzer 2000

The MicroAnalyzer 2000 is a total profiling system designed for detailed surface texture analysis.

           

Being a computer-based system, the MicroAnalyzer 2000 is capable of meeting your current and future surface texture requirements. The system offer the high accuracy of an optical flat reference combined with the most advanced surface texture profiling software available. Our profiling software operates under Microsoft Windows, providing a system with great flexibility that is easy to use.

 

System Features:

The system offers many unique features which are not available on other instruments:

● Single stroke operation allows multiple profile evaluation without retracing the part

● Compare profiles directly using the comparison window 

● View multiple profiles on the screen at the same time

● Selectable roughness filters - 2RC (ANSI), 2RC Phase-Correct, Gaussian, Pk or No Filter 

● Select from over 50 roughness, waviness, texture and form parameters

● Detailed material ratio curve analysis and tables 

● Straightness, slope and radius calculations          

● Export text, graphics, and data into other Windows applications or documents   

● Zoom, pan and measurement commands permit detailed surface evaluation    

● Automatic or ajustable graphic appearance   

● Single stroke inch/metric conversion

Components and Accessories

The part alignment fixture allows the part to be positioned precisely below the tracer. The part can be rotated and translated relative to the tracer without being disturbed on the top mounting plate.

MicroAnalyzer 2000 Software

The software for the MicroAnalyzer 2000 includes a number of features for making surface texture measurements accurately, quickly, and with great flexibility.

Instrument set up consists of joystick positioning assisted by interactive on-screen feedback. With the optional motorized column, tracer centering is semi-automatic. Change tracers in the software with a mouse click; there is no need to recalibrate every time you change tracers or stylus tips. Trace speed and data spacing are fully customizable for the right balance of data collection time versus accuracy.

Data analysis is very powerful and includes a fully configurable roughness filter (none, Gaussian, 2RC, phase-correct 2RC, or Rk) with any standard or arbitrary cutoff. The "form" of the part (tilted line or circular crown) is removed automatically by fitting over a user-specified interval. Use the mouse to specify the interval or enter specific constraints to make the specification repeatable in the presence of differences from part to part. If you trace off one or both edges of a part, these edges can be detected fully automatically with all subsequent results restricted to the part itself.

All the profiles in the analysis (unleveled and unfiltered, leveled, waviness, roughness, etc.) can be quickly displayed, either alone or in any combination. Each can be interactively measured by positioning "measuring lines" with the mouse on-screen.

Material ratio curve (bearing area curve) analysis is comprehensive. The instrument operator can control how the curve is displayed, what potion of the roughness goes into the curve, and weather and how outlying peaks and valleys are removed from consideration. Both the ordinary roughness and the Rk-filtered roughness participate in material ratio curve and amplitude distribution function analysis.

A full range of roughness, waviness, and texture parameters is available. The desired parameters may be selectively enabled, simply statistics may be reported for successive measurements, and the naming of parameters may be switched between ANSI/ASME'85 and ASME'95 standards or ISO standards. Control the interval over which parameters are calculated with simple on-screen mouse movements.

Output information from the program in may ways. Print full or selected results; export profiles or parameters to the Windows clipboard to be pasted into an external document; send repeated measurement (parameter) results to a file for import into an SPC program or spreadsheet; export the raw data in an ASCII format for treatment by any external program.

When data files are saved in their ordinary forma the entire reading along with all setting for instrument set up and data analysis are saved, ready to measure the same part in the same way at any later time. If desired, files may be password locked so that inexperienced operators may take new measurements but not change the data acquisition and analysis settings.

The software runs under Microsoft Windows and includes the usual Windows software features: mouse and menu-driven control, icons, point-and-click dialogs, and information sharing with other applications.

View multiple measurements in separate sub-windows or bring two measurements into the same window for comparison. Interactively measure the difference between two profiles, or compare two material ratio curves on-screen or in laser printed output.

Advanced Capabilities Package

Purchase the advanced capabilities package will add to thee above features: waviness filtering, material probability curve analysis, and power spectral analysis.

Waviness filtering (sometime called band pass filtering) restricts the waviness to wavelengths above the roughness cutoff but less than a waviness cutoff. Waviness is thus separated from long wavelength form error. By selecting cutoffs appropriately, measure the different aspects of a surface production process by looking at specific horizontal size scales.

Material probability analysis is most useful for "plateaued" or two-process surfaces. Two roughness parameters give the roughness of the plateaus and the roughness of the process that produced the valleys, along with the relative proportion of plateaus and valleys. Parameters are calculated according to emerging international standards.

Power spectral density analysis allows you to look at your surface (roughness, waviness, or both) in the frequency or wavelength domain. Look for machining problems at specific frequencies, or confirm  a surface is truly random.

Special Applications

We have a team of engineers who provide a design service for dedicated metrology solutions. This can involve customizing standard PDI instruments to meet our specific requirements or designed unique products.

Precision Devices regularly writes special software for specific customer needs. For example, you may wish to measure part crowning or deviation from a desired shape. Or you may need to measure special parameters not already in the large selection of built-in parameters. Or you may have a need to export your data in specific way for outside analysis or storage.

PDI is able to rapidly develop custom additions to the MicroAnalyzer 200 software to meet your precise specifications. Or, we cab recommend an approach and develop specifications interactively to meet your underlying need.

Field Service

To ensure that all our products are maintained to the standards you require, we offer after sales service. They include an on-site calibration/certification, field service and upgrades.
