Overview

This cycle measures a rotary axis in the current coordinate system by scanning a calibration sphere. The result permits a check of the direction of the rotary axis and the angle travelled in the cycle. With stationary rotary axes, the position of the rotary axis can also be determined.

The cycle can measure both manual axes and NC-controlled axes.

Effectiveness

The examples below define conceivable application cases.

• Detecting incorrect positions of the rotary axis, for example after start-up
• Determining the position of a stationary rotary axis, for example a round table or a stationary rotary axis
• Checking the actually traversed angles of the rotary axis

Condition

To ensure that the successful measurement of the rotary axis, the following requirements must be met.

• Calibrated touch probe
• Mounted calibration sphere whose diameter significantly exceeds the touch probe tip
• During the measurement, the measured rotary axis may not be involved in a kinematic transformation (RTCP / complete transformation)
• During pre-positioning within the cycle, only linear axes and rotary axes involved in a complete kinematic transformation may be moved
