1. A coordinate measuring machine (CMM) having:
- a measuring head provided with a measuring probe;
one or several measurement axes;
one or several actuators designed to displace said measuring head along said measuring axes;
one or several encoders designed for supplying one or several measurement coordinates of the part to be measured;
a control unit for controlling said actuator or actuators,wherein the measuring machine includes a programming mode in which said control unit controls said actuator or actuators to uncouple said actuator or actuators from said measuring head when in said programming mode such that said measuring head can be displaced by an operator through manual actions on said measuring head and said control unit is designed to record the displacements of said measuring head and memorize the measurement points during contact between said measuring probe and said part to be measured;
wherein the measuring machine includes a measuring mode in which said control unit is designed to control said actuators and reproduce the displacements of said measuring head recorded during said programming mode.
