Outline
In ordinary pitch error compensation, compensation is applied to a specified compensation
axis (single axis) by using its position information. For example, pitch error compensation is
applied to X-axis by using the position information of X-axis.
Three-dimensional error compensation is a function that adjusts the current position by
calculating compensation data (for three axes) from the compensation amounts at surrounding
compensation points (eight points) on the basis of the interior division ratio in the
compensation area (rectangular parallelepiped) containing the current position on up to three
compensation axes.
It is possible to change data such as compensation data and compensation magnifications
from a part program by using the programmable parameter input function (G10).
