Abstract
A coordinate measuring machine for determining at least one spatial coordinate of a measurement point on an object, comprising a structure movably connecting a probe head to a base, the structure comprising a plurality of rotary joints and a plurality links, wherein each rotary joint comprises at least one driving unit, wherein the coordinate measuring machine comprises a control unit configured to control the driving units for driving the probe head relative to the base for approaching the measurement point, to receive angular data, and to determine the at least one spatial coordinate of the measurement point based on the angular data.
Claims17
A coordinate measuring machine for determining at least one spatial coordinate of a measurement point on an object, the coordinate measuring machine comprising a structure movably connecting a probe head to a base, the structure comprising a plurality of rotary joints and a plurality of elongate components, the components comprising a plurality of links, wherein each rotary joint comprises at least one driving unit comprising a motor, and at least one measuring unit comprising one or more sensors to determine at least one angle and to generate angular data, wherein the coordinate measuring machine comprises a control unit configured
- to control the motor of each driving unit for driving the probe head relative to the base for approaching the measurement point,
- to receive the angular data, and
- to determine the at least one spatial coordinate of the measurement point based on the angular data,
- characterized in that
- a first rotary joint provides movability of a first link relative to the base about a first axis of rotation and about a second axis of rotation;
- a second rotary joint provides movability of a second link relative to the first link about a third axis of rotation;
- and
- a third rotary joint provides movability of a third link and/or the probe head relative to the second link about a fourth axis of rotation and about a fifth axis of rotation.
