Impact of a Robot Manipulation on the Dimensional Measurements in an SPC-Based Robot Cell

In our study a robot was used to deliver objects for measurement into the Equator gauging system. To investigate robot’s manipulation influence on dimensional measurements, tasks were divided basic functions. Based these functions, nine different robot-manipulation scenarios defined, i.e., from zero full manipulation, two measuring (named Magnet and PKR) six characteristics (rectangular spherical). The determined basis of statistical parameters Cp, R, 6σ obtained system analysis (MSA) type-1 study. results show that degree implemented affects scattering data. However, effect is much more pronounced in case length measurements than with spherical geometries. Different methods (touch-triggering or scanning mode, number sampling points) used, which showed similar This directly indicated R 6σ. Increasing decreases Cp value increases values measurements. There no such course geometries, where remain approximately same. main influential factor decreasing increasing angular misalignment object’s orientation fixture.
