Trouble spots, trends, and potential assembly problems become crystal clear when you use powerful MeasureFit fitting software. This capable software package analyzes all part features at the same time and compares them to a nominal design template that is automatically created from the metrology software inspection routine. The result is a best-fit match between the template and measurement results. MeasureFit's graphic presentation lets you instantly see how well the data fits, since deviations are exaggerated and color-coded.
Multiple fit methods are automatically performed, including Datum Reference Frame Evaluation, Least Squares Best-Fit Analysis, and Minimization of Maximum Errors. All fit methods are performed with complete knowledge of material condition of the feature being evaluated.
MeasureFit automatically performs the most valid fit method based on absence or presence of datum features and geometric tolerances. GD&T results, statistical summaries, and color-coded graphic results of individual data points are immediately displayed.
MeasureFit uses datum alignment and geometric tolerance evaluation based on ASME Y14.5, including material condition knowledge. This allows you to perform detailed MMC analysis on groups of features, as well as take advantage of MMC qualifiers on circular datum features. Profile tolerances may be performed with and without datum references, as per ASME Y14.5. Since the visual appearance of the deviations may be exaggerated, the need for tool offset or process adjustment is easily seen. Parts with multiple datum reference frames are easily accommodated, as features related to each frame are displayed on separate worksheet tabs.
A truly innovative feature of MeasureFit is its ability to automatically construct a SoftGage® nominal design template from a measurement routine. These SoftGages can be applied to the measured geometries. Element gages, such as plug and ring gages, are generated within MeasureFit. Simply drag and drop a gage to the respective feature in the model. Groups of element gages can be combined to create a virtual composite gage.
Kotem developed MeasureFit to conform to the ASME Y14.5M-1994 standard on Dimensioning and Tolerancing, equipping it with these powerful GD&T calculations:
- Implementation of fitting methods – All fitting methods are performed with complete knowledge of material condition of the feature being evaluated
- Construction of datum reference frames
- Calculation of applied tolerances
- Automatic performing of the most valid fit method based on absence or presence of datum features and geometric tolerances
- SoftGages™ calculations.
