Analysis of measuring system MSA methods GRR, Cg / Cgk, VDA 5
The MSA Module is determined for the analysis and processing of the measurement process by methods according to requirements within the automotive industry and their long time archiving.
MSA methods
Software allows analysis processing according to requirements from AIAG, VDA and others:
- RM/ARM - Range method and Average Range Method
- ANOVA Analysis of Variance
- Linearity of measurement system
- Attribute Study
- Methods Cg/Cgk according to Ford, Bosch and VDA
- Measurement uncertainty by EA-4/02
- Measurement and Inspection Processes according to VDA 5
- RM/ARM - Range method and Average Range Method
- ANOVA Analysis of Variance
- Linearity of measurement system
- Attribute Study
- Methods Cg/Cgk according to Ford, Bosch and VDA
- Measurement uncertainty by EA-4/02
- Measurement and Inspection Processes according to VDA 5
Linkage to other modules in PALSTAT CAQ
Module MSA can uses linkage to other modules in the system, especially:
Information regarding dimension of product and tolerance can be used from the Parts database and Control plan modules.
Information about the measurement device in use can be found in the module Measuring instruments.
Information regarding dimension of product and tolerance can be used from the Parts database and Control plan modules.
Information about the measurement device in use can be found in the module Measuring instruments.
Method selection
A newly created analysis can be chosen from the available methods in the MSA module. A method is assigned parameters which are designed by the selected method e.g. number of Controllers, number of Samples etc.
Entry of measured values
Based on the chosen method a table is prepared for the entry of measured values. Some methods allow the entry of reference values for each sample. Measured values can be loaded by drivers into the PALSTAT CAQ system from digital devices or machines.
Results of analysis
After entering the data the results of the measured process analysis can be shown. Each method has indicators dependent on its method (Cg, Cgk, GRR, ndc, Qmp and others).Statistic indicators (R, X, LCL, UCL, ...) are also available.
The entered data can be visualized using a range of graphs and analytical tools.
The entered data can be visualized using a range of graphs and analytical tools.
Reports
One of the components in the MSA module is a series of print reports prepared for different methods. The reports are blank and values can be input by hand. Reports are available in foreign languages (English)
Print reports can be modified or created according to each customer's requirements in the print report editor.

VDA 5: Capability of Measurement Processes
One of the methods in the MSA module is VDA 5 2.edition Capability of Measurement Processes. When entering analysis data into VDA 5 it is possible to chose one from the prepared types of measured processes with a combined model which defines the influence of uncertainties on the measured process. Results of VDA 5 analysis are: - Uncertainty of measured device Ums and coefficient Qms - Uncertainty of measured process Ump and coefficient Qmp - Least measured tolerance Tmin-Ums / Ump
