When setting the jerk and acceleration values, as well as selecting the
suitable filters, take into account
• the running noises of the machine
• the mechanical load (wear)
• the desired machining speed.
Function of the
nominal position
value filters
The function of the filters for rotary axes depends on TCPM (see figure):
TCPM is not active:
• The filters of the "cutter location" type are not active
• The filters of the "position" type are active for all axes
TCPM is active and MP_isAng = TRUE (not available on lathes):
• The filters of the "cutter location" type are automatically activated for all
rotary axes
• The filters of the "position" type are not active for rotary axes
This method provides the following advantage:
Filtering by CLP filters (Cutter Location Point filters) changes the actual
positions of the rotary axes. Based on the kinematics, these changed rotary
axis positions result in changes in the nominal X, Y and Z positions before
the position filter.
