DIAGNOSTICS AND CONTROL OF THE ACCURACY OF AXIS DRIVES FOR AUTOMATICALLY CONTROLLED MULTICOORDINATE METAL CUTTING MACHINES

摘要

It is shown that when estimating the positional accuracy of axial drives in automatically controlled machines, the accumulated and periodic components along a single axis can be estimated separately. Analysis of a circular path along two coordinates makes it possible to determine 17 of the most important machine parameters, including the clearances along each axis, lateral clearances, desynchronization of the drive speeds, off-perpendicular deviations of the axes, and off-parallelism along each axis.
