  4. High Accuracy Universal and Flexible Versatile in any Workpiece Dimensions Reverse Engineering Reduce Measuring and Setting-up Time Allow Dimensional and Geometrical Simultaneously WHY CMM Zeiss - Vista

  5. 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

  6. These systems consist of incremental encoders using a grating scale as a measurement standard. Length-measuring systems (Phocosin)

  7. DESIGN OF CMM • BRIDGE • HORIZONTAL ARM • GANTRY • ARTICULATING ARM Gantry CMM Inspects Huge Auto Stamping Dies

  13. CMM-UMM550

  14. Probe Head Compressed air unit Min requirement 5 bar X,Y,Z Measuring System (Phocosin) CMM Table – Granite X,Y,Z Motor Air Bearing - 6µm high air slit STRUCTURE OF CMM-UMM550

  15. 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

  16. Correlation between probe head output, length measuring data, and resulting measurement value ( MC ) : MC = machine coordinate, PH = probe head output 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. Principle of forming the measured value
