Overview:
Machine
parameters
Critical points for filtering on contour paths are corners, circles and curvature
changes. To optimize the contour accuracy and surface quality at those points,
the following machine parameters are essential.
The individual parameters are described in detail on the page indicated in the
"Page" column. There you will also find further tips for parameter setting.
A guideline on how to set the nominal position value filters and the look-ahead
parameters is provided after the table under "Selection criteria for setting the
mode of operation" on page 1133.
Sometimes different values apply to axis movements at rapid traverse (=
programmed feed rate exceeds the value in MP_maxG1Feed) than to
movements when the tool is engaged. This permits higher dynamics during
rapid-traverse movements.
Parameters that apply to movements at rapid traverse are identified
by the extension "Hi".
