BASIC PRINCIPLE OF MEASUREMENT Measurements are made in a traversing frame with 3 orthogonal axis (X,Y,Z) Displacement along the axes are read by length measuring system (Phocosin) and transferred to an electronic control cabinet Function (Phocosin) to take measurement point determined by the probe head & represent it in a Cartesian coordinate system
Length-measuring systems (Phocosin) These systems consist of incremental encoders using a grating scale as a measurement standard.

Principle of forming the measured value The travel movements of CMM in all axes are recorded by incremental path measuring systems and store in a counter as position. When a probing is made the measured value of each axis is formed from the position stored and the remaining deflection of the probe system
Principle of forming the measured value The probe head does not have to be in the zero position during probing, as the deflection in a probe head axis is exactly copied in the length measuring system of the corresponding CMM axis The probe head output and the CMM length measurement values are added in all 3 measuring axis. Correlation between probe head output, length measuring data, and resulting measurement value ( MC ) : MC = machine coordinate, PH = probe head output
