MeasurLink Real-time is the Statistical Process Control (SPC) MeasurLink module that collects data from Mitutoyo and third-party measuring devices and systems to provide analysis functionality in real-time by displaying control charts or process capability indexes. Three versions are offered so that a customer can choose the version that best suits the requirements, from a standard version providing basic functionality through to the full-spec version offering data handling using Hoops 3D graphics.

MeasurLink Real-Time common functions

Various data views

The measurement results are displayed in various views, including statistical analysis results, data lists, and work process imaging. The display can be switched instantly according to the needs of the operator.

 

Traceability information for each workpiece can be added, for example, serial no., lot no., inspector name, machine no., or cause of problems and remedies.
This information can be used as search criteria when extracting data using the filtering function (RT Pro / RT Pro 3D) when a problem occurs.

The operator is notified when an “Out of Tolerance” or “Out of Control Limit” situation occurs.
The method of notification can be selected from a pop-up window, e-mail (Fig. 1), or log file recording.

Measurement data can be exported to an Excel file. This function is useful if the data needs to be used in a department that does not have MeasurLink.

MeasurLink Process Management for Administrators

MeasurLink Process Manager enables centralized monitoring of real-time measurement information and checking of detailed information from all MeasurLink data collection terminals networked together on the shop floor. Measurement results can be checked in real-time to enable minimizing defects without visiting the shop floor. In addition to simple GO/NG judgments, use of tools such as Manager View, histograms, process capability indexes, etc., make it possible to find abnormal process trends easily.

Displays various types of charts as an at-a-glance guide. The administrator can narrow down all items of data currently being measured into a specific monitoring range of those of critical importance or sort those data (in ascending or descending order) on the basis of process capability index.

Displays bar graphs that can determine
good or bad process capability indexes at a glance. This allows the administrator to sort all current measurement data (in ascending or descending order) on the basis of process capability index, measurement date and time, part name, etc.

Displays various types of events that occur during measurement. This allows the administrator to grasp the state of measurement operation (measurement start/termination, etc.) and the occurrence of an abnormal event (out-of-tolerance, etc.) for all current measurement data.

Events possible to be logged :-

Plant view

Displays a process capability index for each measuring instrument on the plant layout drawing. This allows the administrator to quickly identify the location where an abnormality has occurred.

MeasurLink Evaluation / Analysis Software for Measurement System Analysis (MSA)

This is evaluation and analysis software conforming to Measurement System Analysis (MSA) required in ISO/TS 16949. Implementing MSA evaluation can be performed easily and quickly. ISO/TS 16949 requires that a proper measurement system be achieved by analyzing the accuracy of each instrument and variations in operator effects on repeatability using statistical methods.

This allows the operator to simply input an evaluation method/evaluation condition and measurement data with the Wizard function. The operator can implement MSA evaluation simply by selecting an “investigation type option”, “gage option”, “data input source option”, “parameter option”, etc. Measurement results, charts, and statistical calculation results are presented with the look and feel of Windows Explorer.

• Evaluation method compliant with MSA (fourth edition)

The software can implement evaluation using the following methods compliant with MSA (Measurement System Analysis).

  1. Measurement value tolerance gage R&R variance analysis method
  2. Measurement value tolerance gage R&R range&average method
  3. Measurement value branching gage R&R variance analysis method
  4. Measurement value branching gage R&R average&range method
  5. Measurement value range method
  6. Measurement value simplified method
  7. Measurement value MSA4
  8. Deviation
  9. Linearity
  10. Stability

Analysis chart view

Various charts such as the control chart are effective for analysis/judgment on variations due to operator, the adequacy of gage accuracy, etc., and remedies for problems.

Registration of gage-specific information

  1. Registration of information on gages within the system :-
    This allows registration of gage information on the following items and association with evaluated results. Registration items: Gage name, maker, model, resolution, unit, measuring range, etc.
  2. Information link between MeasurLink Gage Management and this software :-
    This software can use gage information that has been registered in Gage Management directly as options.
    Additionally, since R&R evaluation results are also linked with gage information, the schedule of gage R&R expiry dates can be managed by Gage Management.
