Measuring the kinematic
The kinematics measuring cycle CYCLE996 of the SINUMERIK 840D enables the measurement of the axis kinematics of machine tools with several rotary axes, without the previous large expenditure of time and costs.
The requirements for multi-axis machining can only be fulfilled with precisely working machines. In order to fulfill this criterion, the rotary axes must be correctly oriented to one another. For this purpose, the kinematics of the rotary axes are measured and thus the vectors recorded for digitally or manually adjustable rotary axes, and any corrections entered in the controller. Previously this was only possible with considerable time and technical effort.
With the measuring cycle CYCLE996, a special cycle is available for this application, which can automatically measure the rotary axis vectors with the aid of just a calibration ball and a calibrated probe. In practice, the cycle facilitates checking and improves the process quality as corrections to the rotary axis vectors, e.g. due to temperature fluctuations, mechanical damage of other factors, can be checked automatically.
