Method for machine measurement

摘要

The method involves performing laser-interference measurements such as distance measurements, by reflectors (15a-15e). A mechanical and electrical spindle-exchanging interface (10) is associated to a machine head (3) i.e. fork head. A laser-interferometer (11) is exchanged against a motor spindle by the spindle-exchanging interface and aligned by numeric control (NC)-linear axes (4-6) and NC-pivot axes (7, 8) for the laser-interference measurements. The laser-interferometer is provided with another interface, which corresponds to the spindle-exchanging interface. An independent claim is also included for a system for machine measurement of a NC-machining machine.
