Standard Pattern Measurement To perform a standard pattern measurement (teach): 1 Select the Standard Pattern Tool and then press and drag to completely enclose the desired pattern.
The pattern will be shown in the feature list, and the current stage position and angle will be shown in the detailed view window.
Note Standard pattern features are typically used when a datum alignment will be constructed from two or more pattern features.
Pattern Recognition in Program Playback Once a fully registered datum pattern has been measured (taught) and other features have been probed, the measuring program can be played back. To play the program: 1 Position the datum pattern anywhere in the field of view and then press anywhere in the Live Video window to execute the program. The program will recognize the datum pattern, register the coordinate system and measure any remaining features.
Notes In CNC-enabled systems, a message will be displayed asking for playback confirmation prior to any potential stage movement. Important note for CNC systems The angle of a given pattern is used as a temporary skew in program playback. Because the repeatability of the pattern angle is good only to 1°, subsequent features, particularly when located far from the initial pattern, may not be found automatically. To use the pattern finder most effectively in this case, choose an initial pattern that is located as close to the intended datum features as possible.
