Model 50C has three axes of automated motion plus a fourth manual axis.
As shown in the schematic below, the manual tilt axis can be moved into three
position: vertical, angled and horizontal. In the vertical position, the
machine best measures flat parts such as electronic packages (see
Applications). In the angled position, 3D parts are best measured.
The horizontal position is suitable for tubular parts.
Figure 1. Tilt Positions
The three automated axes are X, Y and Rotation. As shown below, the
sensing beam of the Optimet confocal optics sensor is reflected into two mirrors.
Just like a laser marking machine, the mirrors move the beam in two
directions. In addition the part is rotated by the part turntable.
Software compensates the sensor output with the mirror position to produce
an accurate datacloud.
Figure 2. Three Automatic Axes
In the close up shown below, the Model 50C is set in horizontal tilt to
inspect a jet engine compressor blade. The sensing beam emitted by the
confocal optic sensor reflects off the Y mirror, then the X mirror and onto
the part. The part rotates four times in 90 degree increments to scan
it from all sides.
