Method and device for controlling the measuring operation of a contour measuring instrument

摘要

An approach controller (234) of a coordinate measuring instrument enables a position control loop (RP) and drives an actuator (133) so that a force sensor (1) is brought to a close position under a position control. When recognizing that the force sensor (1) reaches the close position, a contact controller (235) controls a switch (227) to enable a force control loop (RF) and drives the actuator (133) to bring the force sensor (1) into contact with a workpiece under a force control.
