Dynamic Displacement Acquisition System

  Dynamic Displacement Acquisition System         NEW SELBERⅢ


RM-3000 is newly developed system to measure dynamic accuracy of press machines based on the know-how which has been developed by the conventional machine with improved function and operability.It performs under Windows7(64-bit) circumstances.It performs data acquisition more flexibly and performs waveform regeneration. It has the function to export the data to other applications as well. RM-3000

RM-3000 offers the following modes for a variety of measurement.
  • Mode 1 It enables to measure the changes over time of
                  bottom dead center at each stroke or first bound.
  • Mode 2 The measurement (observation) of bottom dead center displacement waveform is
                  available at each stroke.
  • Mode 3 It can be used like a digital recorder.

It achieved easy data conversion.

  1. Measuring data at Mode 2 is able to represent 3 dimensions.
  2. The data measured by RM-3000 can be converted to CSV files.
    It enables to handle the data by using other spreadsheet applications.
Example of the use

  1. Data acquisition to know the characteristics between no loading and loading conditions. Such data will help to select better dynamic accuracy press machines.
  2. Measurement in 3 dimensions (X, Y, Z) by combination of bottom dead center and displacement (slide).
  3. Comparison measurement among bottom dead center displacement, press machine frame, temperature of stamping die and temperature of oil.
  4. Quality improvement of stamped products with existing press machines by utilizing their characteristics.
  5. Measurement of bottom dead center displacement at press machine start time by temperature variation and its countermeasures.
  6. Data acquisition for periodical maintenance of press machines and stamping tools.
  7. Measurement of changes of bottom dead center dynamic accuracy due to changes of press machine SPM. (To know optimum SPM)
  8. Feedback of the data to stamping tool design process and to stamping process to improve the quality. (From the feeling to numerical expression)
  9. Creation of stamping tool design data by considering center of the mass and balance of the wait. (The difference of impact waveform for each press machine and stamping tool)
  10. Selection of effective setting place of slug detecting sensors by detecting the stripper plate surface with sensor.
    Effective utilization of the first bound mode.
