Vertical machining center accuracy characterization using laser interferometer

Reduction of machining errors of a three-axis machine tool by on-machine measurement and error compensation system

“…(1), the measurement data of 21 error components should be required. Laser interferometer system is widely used to measure those errors with high accuracy, but it requires long calibration time and cost [5]. To assess the positioning errors in a more quick and easy way, the volumetric error model is parameterised using the model parameters, which can be easily determined using a touch probe and an artifact.…”

Improving a real milling machine accuracy through an indirect measurement of its geometric errors

“…However, new studies are based on non-rigid behaviour to describe the error structure of the CMM [5]. New geometric error measurements use different laser interferometer techniques based on diagonal displacement, such as in Chen et al [6], Okafor et al [7] and Yang et al [8], taking into consideration thermal influences also.…”

Errors crosstalk analysis and compensation in the simultaneous measuring system for five-degree-of-freedom geometric error

“…The errors will directly influence the machining accuracy or measuring accuracy of the equipment. Measurement of the geometric errors is important [1][2][3][4][5][6][7]. Commonly, a laser interferometer is used to measure the linear errors and an electronic level is used to measure the rotational errors.…”
